We must stress that the subject of airport operations is very broad, so keep that in mind as we discuss it. Here, we are just beginning to scratch the surface by providing you with a high-level overview of the fundamental building blocks. But as with any journey, knowing the fundamentals is the key to making future decisions that are well-informed. So buckle up and get ready to fly as we set out on this informative journey through the crucial world of airport operations. In this topic, you will gain knowledge in the following areas: Components and role players within flight operations: Ensuring all elements involved in take-off, in-flight, and landing processes function harmoniously. Specialists and systems play a crucial role. Airport regulations and regulatory bodies: Specific authorities establish and oversee rules and standards to maintain safety, security, and efficiency. Types of airports: Various classifications of airfields exist, differentiated by aspects like size, function, or location. Airport economic management: Optimising financial operations ensures profitability, encompassing revenue generation, cost control, and strategic investments. The role of air traffic service providers: Coordinating aircraft movements within controlled airspace and on the ground ensures a safe and orderly flow of air and ground-based traffic. Auxiliary services: Support functions include measures for security, ground handling, passenger transport, refuelling, weather data provision, and customs processes. Airport capacity management: Optimising the utilisation of infrastructure like runways and terminals accommodates increasing flight operations efficiently and safely. Let us get started with unravelling the mysteries behind that magical place where aviation becomes visible to the outsider – the airport. 4.2 COMPONENTS AND ROLE PLAYERS WITHIN FLIGHT OPERATIONS Whether a busy international hub or a sleepy regional airstrip, the coordination of flight operations is a fascinating dance of many parts and role players working together. The pilots and flight crews are the backbone of every flight. These individuals are not just the pilots of the aircraft, but also the linkages between various © STADIO (Pty) Ltd Fundamentals of Aviation Management AVM152 107 departments, ensuring that their flight plans are understandable, that they are aware of the weather conditions, and that the aircraft is mechanically prepared for the journey. Beyond just flying the aircraft, they keep in constant contact with ground staff to make sure the luggage is loaded safely and that passengers board in comfort. Air traffic controllers (ATCs) control the airspace and direct these pilots in the background. These experts are the choreographers of the airport, stationed in control towers. Their main responsibility is controlling aircraft movements, both on the runways and in the surrounding airspace, ensuring that routes are safe and clear, and providing pilots with crucial information. Flight dispatchers are often the unsung heroes who make sure that flights can even take place in the first place, even though pilots are ultimately responsible for flights. They carefully plan the routes, taking into account a number of factors such as the current weather, the amount of fuel required, and particular aircraft performance data. They work closely with the pilots, which is essential for efficient and safe flight operations. There may be a lot of action in the air, but there is just as much activity on the ground. Teams involved in ground operations include baggage handlers who make sure all bags arrive at their destinations, refuelling crews who make sure aircraft are ready for take-off, and maintenance teams who inspect and guarantee each aircraft's mechanical integrity. The pushback operators, who make sure that aircraft are safely positioned for their next move, should also not be overlooked. The frontline of airport operations for the majority of passengers is the customer service and terminal staff inside the bustling terminals. They take care of checkins, oversee the boarding procedures, and respond to a wide range of passenger questions. Given the customised nature of charter flights, these roles assume a higher significance in the charter spectrum. The charter coordinators are designed specifically for charter services. They play a crucial part in communicating with various airport departments. They coordinate with ground support services, guarantee timely takeoff and landing slots, and frequently tailor services to the needs of particular clients. A variety of service providers support these main operations. In-flight meal preparation services, specialised businesses that provide essential aircraft maintenance, and even suppliers of essential aircraft parts are among them. © STADIO (Pty) Ltd Fundamentals of Aviation Management AVM152 108 Finally, the additional but equally significant auxiliary services serve as the foundation for airport operations. The security teams watch over each passenger's safety and the integrity of each aircraft. While ramp services and weather service providers make sure that both the environment inside the airport and the conditions above it are conducive for operations, customs and immigration officials streamline border control procedures. Additionally, for those airports with a larger footprint, organisations devoted to managing passenger transportation are crucial for ensuring timely and secure terminal transfers. Understanding this complex interplay is more than just a matter of knowledge for a beginning aviation manager working in a charter environment. It involves tying these threads together to form a seamless whole, ensuring the smooth operation of flights, and providing each passenger with service of the highest calibre.

It sets forth standards, and two critical ones impacting airports are in its Annexes 9 and 14. Think of airports as the meeting points where aviation kisses the boundaries of the nation it is situated in. While planes soar across borders, airports remain grounded, and hence, must follow both aviation rules and national laws. On the flying side of things - what we term the 'air side' - airports everywhere, be it Johannesburg's OR Tambo or a smaller airfield in Mpumalanga, adhere to © STADIO (Pty) Ltd Fundamentals of Aviation Management AVM152 109 ICAO's Annex 14. If you have ever wondered about runway specifications, how navigational equipment should function, or even the way taxiways are marked and lit, this annex has the answers. The FAA calls its compliance proof the AOC (Airport Operating Certificate) while EASA tags it as ADR (Airport Design Certificate). One crucial takeaway here is the emphasis on safety. Every airport must possess a detailed Safety Management System (SMS), describing its proactive and reactive measures during accidents and incidents, and this extends to having a structured fire department and a clear chain of command. Inside the terminals, or the 'land side', the environment changes. Here, the rules of the South African land apply. Whether it is the South African Police Service, the military, or private security firms overseeing routine safety checks, national rules reign. While ICAO's Annex 9 offers guidelines on how to manage passengers and cargo, remember, it is just that – a guideline. Once passengers step into a terminal, they have essentially entered South African territory, and our national customs and immigration agencies oversee their movement and goods. A growing concern for many is the environmental impact of airports. Noise and emission regulations are primarily influenced by the local environment. So, ICAO's Annex 16 sets the tone with noise measurement standards and classifications, but local authorities can adapt based on their specific needs. For instance, Cape Town might have different noise abatement measures when compared to Upington. Finally, ever noticed those unique codes assigned to each airport? ICAO gives a 4-letter code, guiding you to all aeronautical data of that particular airport. For example, while most passengers recognise Johannesburg's OR Tambo International by its IATA code, JNB, its ICAO code is FAOR. It is a simple yet essential distinction, especially when seeking specific operational information. 4.3.2 Other aspects An airport is like a bustling intersection where the world of flying meets the world of driving. Now, imagine this intersection having two sides: one, where all the airplanes move about, known as the "air side", and the other where passengers and visitors go about their business, called the "land side". Think of the King Shaka International or the Cape Town International Airport. When you are walking around where all the planes are parked, refuelled, and maintained, you are on the air side. This side is strictly governed by international aviation laws, under what is known as ICAO Annex 14. But, once you step into the terminals, where passengers are waiting for their flights, grabbing a snack, © STADIO (Pty) Ltd Fundamentals of Aviation Management AVM152 110 or shopping, you are on the land side. This is under the control of local or national authorities, taking recommendations from Annex 9. Even though there is a clear divide between the air and land sides, the boundary can be a tad blurry. You see, even after passengers have gone through security checks in the terminal, they are still on the land side until they cross into the airplane. This is why security and clearance are so vital. Depending on the airport, security checks can be at different points, but no matter where they are, once you are beyond them, you are endorsed to enter the air side. Shifting gears a bit, let us touch on the topic of nationality and jurisdiction. Just like South Africa has its rules within its borders, so does every other country. Now, when a South African plane lands in, let us say, France, it has to respect French rules. However, when it is up in the air flying in French airspace, the laws on board are still South African. It is a fine balance between international respect and sovereignty. Example Imagine a flight from Cape Town to London. Over the Atlantic Ocean, a South African woman gives birth. The baby's nationality is not determined by where over the ocean the birth happens. Instead, the aircraft's South African registration might influence the baby's nationality, as planes are often seen as extensions of their home country. Moreover, South Africa typically grants nationality based on the parents' citizenship, not the birthplace. So, in this scenario, the baby would most likely be South African, given the parents' nationality, regardless of being born in international airspace. Always consult legal experts for specifics, as laws can vary. Next up: security. Now, given the global nature of aviation and, unfortunately, the threats that have arisen over the years, ensuring security has become paramount. ICAO introduced Annex 17 in 1974, focusing on aviation security. While flight safety is about preventing accidents, security is about stopping deliberate harm, like acts of terrorism. Most of this security focus is on airports since, logically, an aircraft is easiest to secure while on the ground. However, security is not solely an aviation concern. In many places, security decisions involve major government departments beyond just aviation authorities. Each country determines its security rules, but they generally follow ICAO guidelines or make them even stricter. An important thing to remember is that any country is responsible for the security of all flights departing from its © STADIO (Pty) Ltd Fundamentals of Aviation Management AVM152 111 airports, not just its own national airlines. This means, for example, that OR Tambo International Airport in Johannesburg must make sure all its departing flights, regardless of where they are headed, meet the security criteria of their arrival destinations. Lastly, the rules of security evolve. As threats change, so do regulations. Over the years, international conventions have been established to address various security concerns, from hijackings to the transport of harmful goods. And while new security measures might sometimes seem inconvenient or stringent to passengers and airlines, they are implemented with safety as the top priority. In a nutshell, airports are complex hubs of movement, rules, and responsibilities, and understanding the difference between air side and land side, as well as the intricate rules of security and jurisdiction, is crucial for anyone stepping into the world of charter aviation management in South Africa. Activity Write down five aspects that illustrate the difference between airport safety and airport security. Prescribed reading Read page XX-XX of your prescribed book before continuing. 4.4 TYPES OF AIRPORTS Airports are far more than just places for planes to depart and arrive. They are critical components of both national and international transportation frameworks, serving as crucial nodes that facilitate movement for both cargo and passengers. For charter operations, whether it is for business or leisure, having a keen understanding of airport types ensures smoother operations and better service. There are several different types of airports: O+D (Origin and Destination) airports: Located predominantly in major cities or capitals, like OR Tambo International Airport in Johannesburg, O+D airports are primarily meant to serve passengers travelling to or © STADIO (Pty) Ltd Fundamentals of Aviation Management AVM152 112 from that specific city. Most passengers at these airports in South Africa either commence or end their journeys here. Regional airports: Situated in secondary cities, these airports might have started small, but many have grown substantially over time. Bram Fischer International Airport in Bloemfontein is a good example. The popularity of low-cost carriers in South Africa, like the defunct Kulula or currently flourishing FlySafair, has boosted passenger volumes at these airports, with some carriers even using them as primary bases. Leisure airports: These airports, like King Shaka International Airport in Durban, cater predominantly to vacationers. The airport's location in Durban draws numerous tourists to the KwaZulu-Natal coast. While they are often the destination for many flights, airlines usually do not have these airports as their primary hubs. Cargo airports: Mainly focused on goods rather than people, cargo airports are vital trade points, strategically situated near significant transport routes or commercial zones. OR Tambo International Airport, for example, plays a dual role. Apart from being an O+D airport, its location and connectivity make it indispensable for cargo movement. Upington International Airport is another example. Refuelling Airports: Historical refuelling points for long-distance flights, these airports, like Lanseria International Airport, still sometimes serve as refuelling stops, especially for specific charter operations. In Africa specifically this is still a relevant category of airport, because of the remoteness of most destinations. 4.4.1 Airports & airlines – a symbiotic relationship: Beyond just being mutually dependent, the relationship between airports and airlines has the power to influence both organisations' growth and day-to-day operations. Significant manifestations of this symbiotic relationship frequently occur. The long-standing relationship between South African Airways (SAA) and OR Tambo International Airport is a notable example in the South African context. Their respective histories are intertwined, and the successes and failures of one frequently have an effect on the other. As we delve further into the history of South African aviation, we come across another informative instance involving Comair and Lanseria Airport. Although it is no longer in business, Comair changed the game at the time. Particularly © STADIO (Pty) Ltd Fundamentals of Aviation Management AVM152 113 noteworthy is the proactive RNAV (Area Navigation) flight procedures that Comair designed and implemented at Lanseria. The main goal of this decision was to improve their own operations and guarantee faster, safer flights. By implementing these cutting-edge navigation systems, Comair could improve schedules, cut fuel use, and optimise flight paths. Comair made a legacy-building decision, but it did not just help them. Long after Comair ceased operations, Lanseria Airport is still benefitting from these RNAV procedures. These updated navigational routes can be used by other airlines flying out of Lanseria, enhancing the airport's reputation for cutting-edge facilities and effective operations. Comair's strategic move highlights how airlines can have a long-lasting positive impact on the airports they operate from when they innovate and invest, highlighting the two parties' mutually beneficial relationship. 4.4.2 The impact of airports on local areas: Airports have vast implications beyond transportation. They act as catalysts for economic development, drawing businesses, and advancing technological growth. Tourism, a sector crucial for regions like Cape Winelands, heavily relies on airports. Cape Town International Airport, for instance, has elevated Cape Town's global status, attracting tourists and businesses. However, it is essential to acknowledge that airports also come with environmental consequences, ranging from noise disturbances to pollution. Balancing these economic advantages with environmental considerations remains a constant challenge. Activity Can you think of another example of an airport benefitting the local community? Write down five benefits that the airport you are thinking of has brought to the local area and people.

There is more to airport economic management, which this section will illustrate in very broad strokes. 4.5.1 Airport ownership In the realm of aviation, the question of airport ownership is multifaceted and varies from country to country. Your textbook elaborates on this from a more global perspective, but let us contextualise it for the South African charter aviation environment. In South Africa, just as internationally, there are not stringent air laws that dictate airport ownership. Instead, ownership is largely governed at the state or local level. As a budding manager in the South African charter sector, you will encounter different kinds of ownership structures, and understanding them will be pivotal in navigating operational intricacies. Privately owned airports: Here, entities or individuals have taken the initiative to own and manage an airport. A prime example is Lanseria Airport, which stands out not just for its private ownership but also for its modern amenities and capacity to handle both commercial and charter flights. Rand Airport is another private facility predominantly serving the general aviation community. Municipally owned airports: Municipally owned airports, such as Margate, Plettenberg Bay, and Wonderboom, occupy a unique space within the South African aviation landscape. Governed by local municipalities, these airports rely on the local government's administrative and financial efficiency to function effectively. However, the South African municipal system, in several regions, has been beleaguered by challenges stemming from corruption and administrative inefficiencies. As a result, municipally owned airports often bear the brunt of these challenges, impacting their operations, development, and overall sustainability. This directly affects you as a charter aviation manager, when for instance an airport you are planning to fly to does not have fuel available or the runway lights are non-functional during the night-time. ACSA-owned airports: The Airports Company South Africa (ACSA) is a state-owned entity that owns, manages, and operates a significant network of major airports across the nation. ACSA's primary objective is to provide world-class airport services that drive economic growth and © STADIO (Pty) Ltd Fundamentals of Aviation Management AVM152 115 tourism in South Africa. The nine airports managed by ACSA include OR Tambo International Airport in Johannesburg, Cape Town International Airport, King Shaka International Airport in Durban, Port Elizabeth International Airport, Upington International Airport, East London Airport, George Airport, Kimberley Airport, and Bram Fischer International Airport in Bloemfontein. For a charter manager operating in South Africa, it is essential to be aware that flying to and from ACSA-operated airports usually involves higher fees than municipal airports. Consequently, when planning charter flights, this can lead to increased costs, influencing flight routing and pricing decisions. Irrespective of who owns an airport in South Africa, there are common threads tying them all. Much like the international model, where landside operations adhere to ICAO annex 9 and airside to ICAO annex 14, South African airports, regardless of their ownership, have to conform to these standards. This means that the overall structure and safety protocols are consistent. A significant takeaway is that, much like their global counterparts, South African airport managements do not hold much sway in deciding which airlines operate from their facilities. This is dictated by international treaties and agreements. Local governments play a pivotal role in environmental regulation of airports. South African airports, like many worldwide, have to be environmentally compliant, adhering to regulations set at the national or local level. In essence, while ownership might differ, the foundational principles of operation, safety, and regulations remain consistent across the board in South Africa. As you delve deeper into the charter environment, understanding these nuances will be instrumental in forging effective partnerships and ensuring smooth operations. 4.5.2 New airport planning Airport planning is a critical component in the aviation world, requiring forwardthinking amidst ever-evolving circumstances. In the South African charter environment, you will find that airport planning becomes an intricate dance of anticipating future needs while adapting to the current demands of the aviation sector. In South Africa, while we have historically boasted several significant airports, there have been moments where the pace of airport planning has lagged. The unpredictable nature of the aviation industry, combined with shifts in airline business models and the broader societal importance of aviation, has occasionally caught planners off guard. Factors such as changing business models of airlines, the balance between domestic and international traffic, and © STADIO (Pty) Ltd Fundamentals of Aviation Management AVM152 116 catering to diverse airline categories like full-service versus low-cost carriers all play pivotal roles. The challenge lies in creating a balance. On one side, you do not want an airport that is too large for its demand, leading to unmet costs due to insufficient passenger income. On the other, an airport too small would result in consistent chaos and disruptions, leading to inefficiencies and dissatisfaction among both passengers and airline operators. The sweet spot, then, is somewhere in the middle, where the infrastructure can manage peak demands without being burdensome during lean periods. Often, planners would use a method of looking at moments of peak demand, such as the average of the busiest hours, to guide their designs. This idea of flexibility is crucial. Airports must be designed to accommodate a variety of factors – from different types of flights (domestic vs. international) to the kind of traffic (business vs. leisure) and even the everchanging specifications of aircraft. Considering these challenges, there is exciting news on the horizon for South African aviation with a plan for a new major airport in the Vaal area (Moneyweb, 2023). This new development will undoubtedly have to integrate all these principles of flexibility and forward-thinking to ensure its relevance and efficiency. Such an airport would not only support the region's growing demands but also set a benchmark for modern, adaptable airport planning in South Africa. For a charter manager, it means potential opportunities for business growth, but it also implies staying updated with new regulations, fees, and operational nuances that such a major hub would introduce.

The air traffic control (ATC) for that airport, commonly known as the cower Control (TWR), manages this CTR and everything happening on the airside of the airport. Their primary job is to ensure all air traffic in and out of the airport flows smoothly and safely, adhering to the © STADIO (Pty) Ltd Fundamentals of Aviation Management AVM152 117 necessary separation standards. In South Africa, ATC operates under the authority of the Air Traffic and Navigation Services (ATNS). Take O.R. Tambo International Airport in Johannesburg, for example. Here, the TWR manages a plethora of incoming and outgoing flights daily. It is split into two main sectors: ground control and approach control. 4.6.1 Ground movement control (GMC) and tower control (TWR) Ground Control (GMC) is all about managing movements on the ground. It as the team that ensures aircraft, vehicles, and even ground support are moving in harmony. You know those tall control towers you see at airports? That is where GMC operates from, giving them a bird’s eye view of everything. Major airports like Cape Town International and OR Tambo even employs ground radar or Surface Movements Radar (SMR) to help them during bad weather. Having an SMR can significantly impact an airport’s ability to function during poor visibility. One of GMC’s main challenges is preventing runway incursions. This is when an unauthorised aircraft, vehicle, or even person finds themselves on an active runway – a leading cause of accidents. Now, at smaller international airports, the ground control might be remotely managed. This system, called RVT (Remote and Visual Tower), enables a major airport's GMC to oversee a smaller airport's operations using live video or SMR. This is not applicable to any South African airport yet. The whole dance starts when a plane preps for departure. Clearance Delivery (CLD) makes sure everything is set for the flight. From pushing back from the gate to taxiing to the runway, GMC orchestrates it all. Once the aircraft reaches the runway's mouth, it is time for Tower Control (TWR) to take over. They clear aircraft for take-off and landing, and hand them over to Approach Control after take-off. 4.6.2 Approach control Surrounding the airport, there is a chunk of airspace known as the Terminal Control Area (TMA). Here, Approach Control takes the reins. Busy hubs, like OR Tambo International Airport, even split this space: one for planes taking off and another for those landing. Aircraft leaving the ground must follow a particular route, the SID (Standard Instrument Departure), while incoming flights adhere to the STAR (Standard Terminal Arrival Route). Both these routes ensure safety, especially since most accidents occur during take-off or landing. © STADIO (Pty) Ltd Fundamentals of Aviation Management AVM152 118 In instances where there is an overflow of incoming aircraft, some might be placed in a Holding Area, circling in a precise pattern until it is safe to land. And if a pilot decides to abandon a landing, there is a go-around procedure ready to ensure the aircraft remains safe. 4.6.3 Landing devices Speaking of safety, ATNS also manages various navigational devices around the airport, including the essential Instrumental Landing System (ILS). An ILS aids pilots as they approach runways, especially under challenging conditions. The ILS is graded in categories based on how much they can assist during limited visibility. There are other landing guidance systems as well, which can be broadly grouped as precision approach guidance systems and non-precision approach guidance systems. Precision approach guidance: This provides the most accurate flight path for an aircraft during its approach for landing. These systems can be so precise that they allow for automatic landings even under severely limited visibility, sometimes as low as 75 meters. That is incredibly limited – on the road, that kind of visibility would bring traffic to a standstill, hence termed as 'zero visibility'. Non-precision approach guidance: While these systems assist pilots during their landing approach, they do not offer vertical guidance. Thus, they are not as exact as their precision counterparts but are still valuable, especially in airports that do not have the infrastructure for advanced systems. The ability to maintain traffic flow during poor visibility conditions is a significant benefit to any airport. If an airport is equipped with advanced landing systems that can handle such conditions, disruptions due to fog or rain can be minimised. Cape Town International airport is an example of this, as they have the best ILS system in South Africa due to Cape Town’s frequently terrible weather conditions. However, there is a catch. Setting up and maintaining these state-of-the-art landing systems does not come cheap. For many airport operators, the financial weight of supporting these high-end systems can be hard to bear. Often, the potential benefits might not seem to justify the hefty investment required. Hence, not every airport can boast of 'zero visibility' auto-landing capabilities. Instead, they strike a balance between safety, efficiency, and cost. © STADIO (Pty) Ltd Fundamentals of Aviation Management AVM152 119 In conclusion, while managing the day-to-day traffic in and around an airport is a complex task, ATC, with the help of advanced systems and procedures, ensures the seamless and safe movement of aircraft. For a budding aviation manager, understanding these nuances can be invaluable in ensuring smooth operations, especially in challenging environments. Understanding the services and facilities of the airport where you are planning for your crew to fly to with will ensure that you make good decisions when it comes to organising charter operations. Activity Write down three examples each of precision and non-precision approach guidance. Prescribed reading Read page 80-83 of your prescribed book before continuing. 4.7 AUXILIARY SERVICES There are several additional services in and around the airport that is essential to its efficient and safe functioning. 4.7.1 Aviation security In the aviation world, security is of utmost importance, and South Africa is no exception. Think about OR Tambo International Airport in Johannesburg, one of Africa's busiest airports. Security measures here are implemented to ensure the safety of passengers, crew, and the aircraft. It involves everything from screening passengers and their luggage to safeguarding against potential threats like terrorism. Procedures might remind you of the security checks you go through before boarding, with X-ray machines, metal detectors, and sometimes even sniffer dogs. For a charter aviation manager, understanding the nuances of aviation security is critical. Even though charter flights might be perceived as more private or exclusive, they are not exempt from stringent security measures. The safety and © STADIO (Pty) Ltd Fundamentals of Aviation Management AVM152 120 well-being of every passenger, crew member, and the integrity of the aircraft lie in the hands of the management. By being well-versed in aviation security protocols, a charter aviation manager can ensure that the entire flight process, from boarding to disembarkation, is seamless and hassle-free. For instance, ensuring that security screenings are efficient can help avoid unnecessary delays, and being aware of the latest security threats can guide the manager in implementing preventive measures. Moreover, customers who choose charter flights often prioritise privacy and exclusivity; a manager who guarantees robust security practices enhances the company's reputation and customer trust. 4.7.2 Ramp services Ramp services are the various operations that occur on the ground when an aircraft is at the terminal but not in motion. For instance, at Cape Town International Airport, after a plane lands and taxis to its designated spot, several services kick into action. These include offloading and loading of luggage, catering services bringing in fresh food for passengers, and technicians checking the aircraft's technical health. It is a well-coordinated dance to ensure quick turnaround times. Ramp services are equally essential in charter aviation. While the scale might differ from commercial airlines, the need for efficiency remains. A charter aviation manager should ensure that luggage is handled with care to prevent damages or losses, that the aircraft is well-maintained and ready for the next flight, and that any onboard requirements specific to charter passengers (like specialised catering or equipment) are taken care of. A smooth turnaround process can lead to better flight schedules, improved customer satisfaction, and ultimately, more business. 4.7.3 Passenger transport This does not only mean transporting passengers by air. Once you have landed at, say, OR Tambo International Airport, and you are making your way to the terminal building, what about those shuttle buses or trams that transport you? They are also a part of passenger transport services. It ensures that passengers get from the aircraft to the terminal safely and efficiently. Charter flights often cater to a niche clientele that expects punctuality and efficiency. Knowing the ins and outs of passenger transport ensures that passengers move from the terminal to the aircraft swiftly and comfortably, enhancing their overall experience. It is not just about transport, but about ensuring the journey is in line with the exclusive nature of charter services. © STADIO (Pty) Ltd Fundamentals of Aviation Management AVM152 121 4.7.4 Fuelling services Just like cars need petrol, aircraft need fuel. At airports, specialised vehicles, often referred to as 'bowsers', provide this essential service. They are responsible for refuelling aircraft so that they are ready for their next journey. These services have to be swift and safe, ensuring that there is no fuel spillage, and the correct type and amount of fuel is delivered. At larger airports, the fuel is stored in massive tanks under the tarmac of the ramps, and pumped directly to the aircraft via connectors at each parking stand. Efficient fuelling services mean timely departures. For a charter aviation manager, understanding the fuelling process, knowing the right contacts, and ensuring that there are no delays in this process can lead to better operational efficiency. Additionally, being aware of fuel costs and consumption rates can aid in budgeting and operational decisions. 4.7.5 Weather services Weather plays a crucial role in aviation. Pilots need to be updated about current and expected weather conditions for safe flying. For this reason, airports like OR Tambo International Airport will have meteorological services. These services offer real-time data on weather conditions, forecasts, and any sudden changes that could affect flight operations. At smaller airports, these services can usually be accessed online via the provider’s website. In South Africa, the official meteorological provider for aviation services is the South African Weather Services (SAWS). Charter flights might sometimes operate from smaller airports or aerodromes that do not have extensive meteorological services. A charter aviation manager, equipped with knowledge of weather services, can proactively seek out relevant weather information, ensuring the safety of flights. It also aids in effective communication with passengers about potential delays or changes in schedules due to weather conditions. 4.7.6 Customs and immigration If you have ever taken an international flight, you have interacted with customs and immigration services. When a flight from London lands at OR Tambo, for example, passengers have to go through immigration where their passports and visas are checked. Customs officials are also present to ensure that goods entering or leaving the country comply with South African laws, checking for prohibited items or ensuring the correct duties are paid on imported goods. © STADIO (Pty) Ltd Fundamentals of Aviation Management AVM152 122 If the charter company operates international flights, even occasionally, it is imperative for the manager to be well-acquainted with customs and immigration processes. This knowledge ensures a hassle-free experience for passengers and can prevent potential legal complications. Being adept in this area can also facilitate smoother interactions with immigration officials and expedite processes, which is especially valuable for charter clients who might be on tight schedules.

Airports are increasingly turning out to be the limiting factor given the aviation industry's explosive growth in terms of both passengers and aircrafts. It is challenging to simply construct new airports or expand existing ones. It is a protracted process that requires significant resources and, most importantly, everyone's consent. This is especially true in populated areas where it can be difficult to locate suitable locations for new airports. Additionally, there is a clear pattern that most travellers prefer to fly around the same times, leading to peak travel times at airports. Because these times coincide with peak travel demand, every airline wants to accommodate them. Airports may therefore be underutilised during other times of the day, despite © STADIO (Pty) Ltd Fundamentals of Aviation Management AVM152 123 being busy and overcrowded during these peak times which illustrates how important it is to use airport space wisely. This presents a challenge because an airport has many logistical components, each of which operates under unique dynamics and capacity restrictions. Example An airport may be accommodating a large 600-seat A380 at the same time as a small propeller plane with 30 passengers. Both are regarded as one aircraft movement, but they have very different effects on the resources at the airport. The intricacies continue when an aircraft is stationed. The processes that begin on the landside, like passengers boarding or luggage being loaded, move to the airside. Juggling all these operations smoothly is quite a task. This is why many airports have centralised their daily operations into an Airport’s Operations Control Centre. It ss like the brain of the airport, ensuring everything runs seamlessly. Airports perform an intriguing balancing act. Everything must be quick to move passengers through the airport efficiently. However, from a financial standpoint, airports profit when visitors stay longer inside and make purchases from a variety of shops and restaurants. This period, also known as "dwell time," creates a paradox for airport management. To maximise operational efficiency, they want passengers to move quickly, but they also want them to spend more time dining and shopping, which increases non-flight related revenue. In essence, managing an airport's capacity entails more than just handling planes and travellers. It involves a delicate balancing act between operational, logistical, and financial factors. Understanding these subtleties as a member of the South African charter industry can help you gain knowledge of how airports operate and how your operations fit into the bigger picture. 4.8.1 Airside capacity: aircraft movements In the realm of international aviation, various factors play a pivotal role in ensuring smooth operations at airports. Aircraft stands, essentially the parking spots for planes at the terminal, dictate how many aircraft an airport can handle simultaneously. Their design caters to various aircraft sizes, with wide-body stands being the most expansive. In some airports globally, the number of these © STADIO (Pty) Ltd Fundamentals of Aviation Management AVM152 124 stands is limited, causing potential operational delays, especially if an aircraft needs technical maintenance. Furthermore, the fuelling capacity of an airport is crucial. While some airports close to seaports or with pipeline connections to refineries have a constant supply, others, particularly in remote or high-altitude locations, might face challenges. Fuel is typically stored at a 'fuel farm' and then distributed either via underground pipelines leading to hydrant wells at the aircraft stand or by fuel trucks. The number of aircraft stands and fuel trucks determines an airport's fuelling capacity. At some international airports, larger, long-haul aircraft relying on trucks for fuelling can significantly impact this capacity – imagine how many trucks would be needed to fill up an Airbus A380 with fuel! For aircraft to move from their parked position, especially when facing the terminal, a pushback procedure is needed. This is where towing capacity comes into play. Traditionally, tow bars, specific to each aircraft type, were used. However, modern towing vehicles can universally lift the aircraft's nose wheel, allowing flexibility in handling any aircraft. Airport slots are essentially permissions for an airline to access an airport within a set timeframe. Some airports, especially busy ones, have restrictions on how many Aircraft Traffic Movements (ATMs) they can handle, which leads to slot coordination. Within the EU, for example, independent coordinators manage these slots at full or coordinated airports. Airlines operating at such airports get 'grandfather rights' which means that once a slot is assigned to them, they retain it provided they keep using it. These slots become especially valuable at major hubs, so much so that airlines have bought other airlines mainly to acquire their slots! In South Africa, all slots are managed by the ATNS Central Airspace Management Unit (CAMU). Weather, as you can imagine, is a major factor in airport operations. While we might not deal with snow or extreme cold in South Africa, understanding the international context is essential. Strong winds can restrict take-offs and landings. Heavy fog impacts visibility, making instrument landing systems (ILS) and ground radar crucial. If vehicles or aircraft move within the ILS protected area during fog, it drastically reduces the runway's landing capacity. Heavy rainfall can slow down ground operations, affecting the Turnaround Time (TAT) for aircraft. In colder regions, snow can render an airport inoperative, with operations resuming only after snow clearance. A significant concern in frosty conditions is the de-icing of aircraft before takeoff. It is very important, because ice formation on wings can be deadly, © STADIO (Pty) Ltd Fundamentals of Aviation Management AVM152 125 compromising flight safety. This procedure involves spraying a glycol-based fluid onto the aircraft to melt ice and prevent further formation. While it is unlikely you will face such challenges in South Africa's temperate climate, it is a routine in colder countries. Some airports have specific areas for de-icing to avoid stand pollution, and ideally, these are located close to the runway because the glycol's effectiveness diminishes over time. Lastly, it is essential to understand that airports are optimised based on their prevailing weather conditions. Those in windy areas might have multiple runways in various orientations, and those in colder regions have vast de-icing capacities. They are designed to handle typical adverse conditions, but unforeseen weather events can still pose challenges. In conclusion, as a charter aviation manager in South Africa, while you might not deal with every single issue mentioned above, having a comprehensive understanding of the intricacies of airport operations internationally will undoubtedly broaden your perspective and better equip you for challenges and opportunities in the evolving aviation landscape. 4.8.2 Landside capacity: passenger movements At its core, effective airport management revolves around smart planning and efficient coordination. A key component is gate planning, which deals with ensuring that aircraft are allocated the right spaces at airports. Just like how at bus stations there are designated stops for different buses, aircraft, depending on their size, get assigned specific gates. Larger aircraft, like those used for international flights, need more space, so they are allocated wide-body gates, whereas smaller domestic flights use narrow-body gates. In South Africa, as is the case globally, the quick turnaround at these gates is crucial. An aircraft occupying a gate longer than necessary due to unforeseen issues can cause a domino effect of delays. Think of it like traffic in Johannesburg during peak hours - one car breaking down can lead to a whole jam! Similarly, gate congestion can have ripple effects. Plus, with our country being a popular long-haul destination, the unpredictability of exact arrival times for such flights can pose a challenge. Additionally, each gate has two parts: one that interfaces with the aircraft (airside) and the one where passengers wait (land-side). Given the trend of increasing seating capacities in aircraft, often the waiting lounges on the landside might feel a bit cramped, especially if we are talking about a charter flight packed to capacity with tourists eager to experience South African wonders. © STADIO (Pty) Ltd Fundamentals of Aviation Management AVM152 126 Moving on to luggage handling, it is more than just throwing bags onto a conveyor belt. Passengers entrust airlines with their belongings, which are labelled and sorted in the belly of the plane or in containers. A significant chunk of the process occurs underground, in what can be termed as the airport's 'cellar'. Security screenings, customs checks for international flights, and sorting based on destination and flight class are all part of this meticulous process. For charter operations in South Africa, ensuring luggage reaches its intended destination, especially when dealing with tourists who have connecting flights, becomes paramount. Then we have the cargo terminal. While passenger terminals are bustling with people, cargo terminals handle goods - from perishable foods to electronics. Some airports in South Africa may focus mainly on cargo, given our country's rich export industry. While the aircraft handling remains largely the same, the nuances of managing different types of cargo are unique. For example, transporting wines from the Cape Winelands requires temperature-controlled storage. Likewise, if we are exporting local crafts or importing electronics, the infrastructure has to support it. And, given the limited space at many airports, finding enough room for these large cargo terminals can be akin to playing a game of Tetris. One of the challenges here, especially relevant for a charter aviation manager, is the constant time pressure. Just as with passenger flights, cargo needs to be appropriately packaged, balanced, and scheduled for transportation to its next destination, often within tight timelines. Moreover, considering South Africa's geographical layout and the need for goods to be transported across the country, good road infrastructure becomes essential. This ensures lorries carrying cargo do not interfere with the regular inflow and outflow of passengers, much like ensuring trucks and cars use separate lanes on highways to avoid congestion. Whether it is efficiently managing the gates, ensuring luggage gets to the right flight, or handling diverse cargo, the key lies in planning, foresight, and adapting global best practices to the unique South African context. As a charter aviation manager here, understanding these nuances and tailoring them to fit our local needs will be your daily mission. Welcome to the thrilling world of aviation! © STADIO (Pty) Ltd Fundamentals of Aviation Management AVM152 127 Summary Airport operations are a vast and complex network, requiring a synergy of many components and role players. At the heart of these operations lie flight processes - take-off, in-flight, and landing - all of which need a seamless orchestration of specialists and integrated systems to ensure smooth functionality. It is much like a well-rehearsed orchestra, where every instrument needs to play its part perfectly to create a harmonious symphony. Like all major industries, aviation does not function in isolation. There are regulatory bodies and authorities that lay down the rules of the game, ensuring that safety, security, and efficiency are paramount. They act as the watchdogs of the skies, making sure every flight adheres to global standards and protocols. Airports themselves come in various shapes and sizes. Some are vast international hubs, facilitating global travel and commerce, while others are more localised, serving specific communities or functions. Factors such as location, size, and functionality differentiate these airports, catering to diverse needs from commercial passenger flights in metropolitan areas to cargo operations in industrial zones. Money talks, even in aviation. Economic management is crucial, as airports are more than just transit points; they are businesses. Financial operations need to be optimised for profitability, striking a balance between generating revenue, controlling costs, and making strategic investments. An airport that does not manage its finances well is like a aircraft without fuel—it will not go far. Air traffic service providers play a pivotal role in this intricate dance of the skies. Their task is to ensure that every aircraft, both in the air and on the ground, moves in a safe and orderly manner. Their eyes and tools keep a constant watch, guiding planes much like traffic policemen guide vehicles on a busy intersection. Additionally, airports offer a suite of auxiliary services. These range from the visible - like passenger transport and baggage handling - to the behind-thescenes operations like security measures, refuelling, weather data provision, and customs processes. It is a vast machinery where each cog has a role to play. Lastly, with the ever-increasing volume of flights, managing airport capacity has emerged as a crucial task. It is all about making the best use of available infrastructure, ensuring that runways, terminals, and gates can handle the surge of operations both safely and efficiently. Understanding these facets is crucial for making informed decisions in entry-level airport management. © STADIO (Pty) Ltd Fundamentals of Aviation Management AVM152 128 Self-Assessment Questions The purpose of these self-evaluation questions is to see how well you understand and can use key ideas from the topic.

Demonstrate the ability to articulate the diverse factors inherent to the entry level management of aircraft operations in an aviation environment. Managing aircraft operations in a charter environment is more than just ensuring aircraft take off and land safely. Understanding the intricate dance that begins before an aircraft even takes to the sky is key. From rigorous processes that ensure an aircraft's legality and safety to the strategic considerations involved in using different aircraft types efficiently, aircraft operations management is complex. Of course, every aircraft is thoroughly inspected before flying to ensure its safety and suitability. But after take-off, the aircraft becomes a production unit and an economic entity with far-reaching effects. To ensure not just the aircraft's operational efficiency but also its economic viability, prudent decisionmaking is required. Beyond the aircraft, the operational ecosystem is crucial. Original equipment manufacturers (OEMs) influence operational strategies for maintenance, repairs, and overhauls, not just part supply. OEMs, in conjunction with aircraft maintenance organisations (AMOs) act as partners to keep aircraft running smoothly, reduce downtime, and maintain performance. However, operations are not isolated. From changing weather to global navigation, the skies are unpredictable. A good manager must be aware of these factors and plan around them. The topic of operations management is vast and varied. While we aim to provide a foundational understanding of these complexities, you must recognise that we are painting in broad strokes - we are barely scratching the surface of aircraft operations management, a complex field. This topic simply aims to round out the entry-level aviation management knowledge obtained in the previous three topics with a very swift aircraft operations overview, providing a basic © STADIO (Pty) Ltd Fundamentals of Aviation Management AVM152 130 understanding of the many factors that go into taking an aircraft to the skies. In this topic, you will gain a basic knowledge in the following areas: Aircraft certification: The process through which aviation authorities verify that an aircraft meets safety and performance standards. The aircraft as production unit: Viewing the aircraft as a unit that generates revenue through its operational use. Aircraft economics: The study of financial factors influencing the operation, buying, and selling of aircraft. Managing operations with different aircraft types: Coordinating flight operations that involve various models and sizes of aircraft. Managing aircraft operations in terms of supply and maintenance: Overseeing the logistical and upkeep needs of an aircraft to ensure its continuous safe operation. The role of original equipment manufacturers: Entities responsible for producing and supplying initial equipment parts for aircraft. Management of processes related to maintenance, repair and overhaul (MRO) suppliers: Overseeing the services and supplies needed to maintain, fix, and refurbish aircraft. Managing operations with awareness of meteorological and navigational aspects: Coordinating flight operations with a foundational understanding of technical aspects related to weather conditions and navigational challenges.

Consider purchasing a car. That car must pass several safety inspections before being allowed to drive. Similarly, certification is required for aircraft before they can fly. Who is responsible for ensuring the safety of these aircraft now? The National Aeronautical Authority (NAA) of the nation where the aeroplane was manufactured is responsible. This organisation issues what is known as a © STADIO (Pty) Ltd Fundamentals of Aviation Management AVM152 131 Certificate of Airworthiness (CoA), which is essentially a seal of approval that states, "This aircraft meets all safety regulations and is good to fly." But that is not where the story ends. An Airworthiness Review Certificate (ARC), which needs to be renewed every year, is also required for each individual aircraft. Consider this to be the yearly inspection for your car. Without these certificates, an aircraft is not permitted to fly. Just like that. Big players like the FAA (for US-made aircraft like Boeing) or EASA (for Airbus) may be names you are familiar with. These organisations guarantee the safety of the aircraft made in their region. However, their impact is widespread. To ensure that they can sell their aircraft internationally, other nations frequently align their standards with those of these major players. The following are some key terms you will come across when it comes to aircraft operational regulations: 1. Original type certificate (OTC): When a completely new type of aircraft is made, it needs this certificate. If there are changes later, like a new engine, it gets an Amended Type Certificate (ATC). Minor modifications, like a new system, might get a Supplemental Type Certificate (STC). 2. Parts manufacturing approval (PMA): If someone wants to produce a part that was not in the original certification, they need this. 3. Airworthiness directive (AD) note: If there is a flaw detected in an aircraft, this note orders a fix. If the flaw is big enough, an entire fleet can be grounded. 5.2.1 The role of the South African Civil Aviation Authority The South African Civil Aviation Authority (SACAA) is the main body responsible for regulating aviation safety and security in South Africa. Its functions include overseeing airports, aircraft operations, crew, and technical personnel. Their regulations and standards are developed to align with international best practices and standards set by the International Civil Aviation Organisation (ICAO). They implement the above regulations as follows: 1. Certificate of airworthiness (CoA) in South Africa: Any aircraft that wishes to operate in South African airspace must possess a CoA issued by the SACAA. This certificate ensures that the aircraft has been inspected and meets all the required safety and technical standards. It is similar to a vehicle roadworthiness certificate, but for aircraft. © STADIO (Pty) Ltd Fundamentals of Aviation Management AVM152 132 2. Regular inspections: Aircraft in South Africa are required to undergo periodic inspections to ensure they maintain the standards set out in their CoA. These inspections can be regular maintenance checks, annual reviews, or surprise inspections by SACAA officials. 3. Licensing and training: The SACAA oversees the licensing of pilots, engineers, and other technical personnel. They ensure that all individuals involved in aircraft operations have the necessary training and meet the set criteria to hold their licenses. Continuous training and periodic reevaluations are mandatory. 4. Enforcement: If airlines, operators, or individuals fail to adhere to the regulations set by the SACAA, there are consequences. These can range from fines to license suspensions, grounding of aircraft, or even criminal prosecution in severe cases. 5. Airworthiness directives (AD): The SACAA also issues AD notes, similar to other countries. If a design flaw or other issue is detected in an aircraft model operating in South Africa, the SACAA can order fixes or even ground entire fleets until the issue is resolved. 6. Collaboration with international Entities: Given the global nature of aviation, the SACAA frequently collaborates with international entities like the FAA, EASA, and ICAO. This ensures that South African aviation standards are in line with global best practices and that aircraft operating in and out of the country meet international standards. Every component of an aircraft, from the engines to the smallest parts, must pass stringent inspections and obtain various certifications. To ensure aviation safety, a complicated but essential system is in place. Additionally, approvals are required for companies that create and manufacture aircraft parts, ensuring that the entire process - from design to manufacturing - is checked for efficiency and safety.

This combination of the potential cargo and the distance it can be moved establishes the productivity of the aircraft. However, the charter company's planning and operations will determine how efficiently this potential is used. 5.3.1 Aircraft weights and their implications Unique to aircraft, compared to other vehicles, is the challenge of overcoming gravity, which makes the weight of the aircraft and its load critical. This weight is typically measured in kilograms or pounds. Additionally, the distance an aircraft can travel, its range, depends on the weight of the fuel needed for that journey, making the understanding of various weights essential to grasp the productivity of an aircraft. The first of these weights is the manufacturer’s empty weight (MEW), which is the weight of the aircraft ready to fly but without any customisations like the interior design or any additional equipment chosen by the charter company. Ideally, each aircraft of the same model will have a consistent MEW, indicating consistent quality and production standards from the manufacturer. Following this is the operating empty weight (OEW), which pilots might sometimes refer to as the dry empty weight. OEW considers the MEW along with the interior, the design on the exterior, any additional equipment, safety tools, the flight crew, and their belongings. Essentially, this weight represents the whole aircraft without its passengers, cargo, and fuel. Given these variables, even aircraft of the same model might have varying OEWs, depending on the charter company's preferences for interior amenities. The next key weight is the maximum zero fuel weight (MZFW), limited by the aircraft's structural design. Subtracting the OEW from the MZFW gives the maximum load the aircraft can carry. For charter flights carrying passengers, the © STADIO (Pty) Ltd Fundamentals of Aviation Management AVM152 134 plane is seldom loaded to its MZFW as the cabin's volume is used for seating passengers, their baggage, and occasionally additional cargo. However, when chartering solely for cargo, the aircraft is often filled to its MZFW. This weight is consistent across all aircraft of a specific model and is determined during certification. The maximum take-off weight (MTOW) is another certified weight that sets the limit for safe take-off and climb. All aircraft of a particular model will have the same MTOW. The difference between the MZFW and the MTOW represents the weight available for fuel, and combined with the aircraft’s fuel efficiency, this determines its range. It is crucial to recognise that when an aircraft is loaded to its MZFW, its range gets restricted due to the limited fuel it can carry. Conversely, if the aircraft is filled with fuel to its max, its cargo capacity is reduced. This dynamic means the aircraft does not have set cargo and range capabilities, and charter operators often find a balance between the two, sometimes even varying with each trip. Activity Write down the difference between an aircraft’s MAUW, OEW MZFW and MEW. Prescribed reading Read page 115-123 of your prescribed book before continuing. 5.4 AIRCRAFT ECONOMICS When we think about aircraft, the first thing that often comes to mind is its technical capabilities - how fast it can fly, how far, and how many passengers it can carry. However, from a charter business perspective, there is another crucial angle to consider. Think of aircraft not just as flying machines but also as significant financial investments that have the potential to generate profits. Aircraft are, without a doubt, expensive to purchase. For instance, a smaller jet, like the 70-seat Embraer 175, might have a price tag of around USD$30 million, whereas the colossal Airbus 380-800 can soar beyond USD$400 million. From a charter perspective, a new Pilatus PC-12NG costs around USD$5-6million, and © STADIO (Pty) Ltd Fundamentals of Aviation Management AVM152 135 even though they are smaller in size, helicopters are expensive too - a brand new Bell 407GXI will set you back USD4 million, and even a very modest Robinson R44 is around USD$650 000 (2022 prices). But in the charter world, it is not just the price tag that matters. The real question is: how much profit can this aircraft bring in for the charter company? The larger the aircraft, the more it might cost upfront, but it also has the potential to bring in more revenue, especially if you are chartering it for bigger groups or longer journeys. Today's aircraft, if operated efficiently, have the potential to earn back their initial investment in roughly a decade. Considering that the average aircraft can be in service for about 25 years, this means that there is potential for a substantial return on investment (ROI). This potential profitability makes aircraft a tempting proposition for entities that have the money to invest, such as banks or institutional investors. Here is where things get particularly interesting for charter businesses: owning an aircraft and operating it do not always go hand in hand. Due to the substantial costs involved and the promising ROIs, it is common to see a separation between the owner and the operator. For example, a bank or leasing company might own the aircraft, while a charter service operates it. This division allows for flexibility in financial strategies, such as leasing instead of purchasing, which can be beneficial for charter companies aiming to optimise their operations. 5.4.1 Aircraft economical terminology We spoke a little about aircraft economics in section 3.3.2, but there are a few terms that are worthwhile clarifying in a bit more detail, as they all have important roles to play in aircraft economics: Wide-body aircraft: These are the big aeroplanes you frequently see on long-haul flights. Sometimes they are used for shorter routes, especially if the destination airport has limited slots. These large birds used to have four engines, but nowadays many just have two. They are available in a variety of sizes, just like smaller aircraft, but each size has advantages and disadvantages. The bigger aircraft, the heavier. This means that the aircraft's weight may restrict its range during lengthy flights, though typically the smaller versions of these wide-bodies can travel the furthest on a single tank of fuel. © STADIO (Pty) Ltd Fundamentals of Aviation Management AVM152 136 Narrow-body aircraft: The more prevalent single-aisle aircraft that you frequently see are known as narrow-body aircraft. Their versatility makes them efficient on short and medium-haul routes. They are great for charter services because they can access more airports, including those that are unable to handle larger planes. Smaller groups or corporate charters benefit from their fewer seats than wide-bodies. When offering competitive charter rates, their lower operation costs can be appealing. Freighter aircraft: These aircraft are the backbone of aviation, carrying cargo rather than passengers. Some are factory-built, while others are converted from aircraft. Since used passenger planes have depreciated, converting them can be cheaper than new freighters. Some airliners are not good cargo aircraft. Since cargo is heavier than passengers, a good cargo aircraft balances weight and space. Dedicated aircraft are useful for shipping hazardous or large items. Instead of flying nonstop, cargo planes may refuel to maximise fuel efficiency. Cycle Cost: The cost of a single flight, from take-off to landing. Big, heavy aircraft require more fuel and maintenance, especially during take-off and landing, making each flight more expensive. Thus, longdistance planes, which are heavier, are most cost-effective for long flights. Fleet commonality: The charter industry favours fleets with similar aircraft. Why? Since pilots and engineers only need to learn one aircraft type, it reduces training costs. Since parts can be used across aircraft, maintenance costs are reduced. It is simpler to manage and maintain if you think of it like having a fleet of comparable rental cars. Some manufacturers make aircraft of different sizes with similar engines and cockpits, making them easier to operate and maintain. Example Airbus makes the A319, A320, A321, A330, A340, and A380. They cater to shorthaul regional flights to long-haul international routes and vary in size and capacity. However, design, engineering, and systems are similar. Imagine a charter company's fleet is mostly A319, A320, and A321. The Airbus A320 family has similar cockpit designs despite their different capacities and ranges. This means an A320 pilot can fly an A319 or A321 with minimal training. © STADIO (Pty) Ltd Fundamentals of Aviation Management AVM152 137 For the charter company, this means significant training savings. These aircraft share design and engineering, making many parts interchangeable. Thus, if the charter company stocks spare parts, they can be used on multiple aircraft, reducing inventory costs and maintenance turnaround times. The A330, A340, and A380 are larger and serve different purposes. They share technologies, design philosophies, and sometimes components with smaller competitors. Airbus promotes "family commonality," which means learning to fly one Airbus aircraft makes it easier to fly another. Aircraft Values: Understanding the value of an aircraft is essential in the charter industry. Age, maintenance history, hours flown, after-sales support and market demand all affect an aircraft's value. It is not just about buying the aircraft for charter operations, but about maintaining its resale value. This requires regular maintenance, timely upgrades, and prudent aircraft use to avoid rapid depreciation. Aircraft Financing: Aircraft are expensive. Few companies, especially new ones, have enough cash to buy. Herein lies the role of aircraft financing. It is like a mortgage. The charter industry offers several aircraft financing options. Traditional loans are common and require interest payments. Leasing allows you to rent an aircraft for a set period and buy it later. Fleet upgrades and market adjustments are easier for charter companies with leases. The cost of owning an aircraft is not solely determined by its purchase price. If you are in the charter business, it is essential to understand that the actual ownership cost per flight hour depends more on how frequently that aircraft is in the air and how efficiently it is scheduled. An aircraft that is frequently chartered and efficiently managed can spread its costs over more flight hours, potentially making it more profitable in the long run. Aircraft economics are multi-faceted and complex, and having a broad understanding of the basics will serve you well as you enter the world of aviation management. Activity Research aircraft commonality. Name another range of single-manufacturer aircraft (other than Airbus) with an intentionally high degree of commonality. © STADIO (Pty) Ltd Fundamentals of Aviation Management AVM152 138 5.5 MANAGING OPERATIONS WITH DIFFERENT AIRCRAFT TYPES Versatility is prized in the world of charter aviation. Contrary to scheduled airlines, which may have the luxury of standardising their fleet, charter businesses must accommodate a variety of customer needs. This means that on any given day, the charter company might be preparing a larger aircraft for a group travelling a longer distance while also flying a small business executive on a quick trip using a light jet. First, think about the effects on the crew and pilots. Each type of aircraft needs specialised training. Your pilots and crew must be trained in a variety of aircraft types if your fleet is diverse. This may result in higher training costs and more challenging scheduling. A manager must effectively schedule pilots based on their qualifications to guarantee that each flight has the right crew for the particular aircraft. Then there is the issue of maintenance. There are various maintenance requirements, schedules, and parts needed for various types of aircraft. It is essential to keep track of these schedules and guarantee that each aircraft receives maintenance on time. The parts inventory also turns into a balancing act. While it may be tempting to keep an extensive inventory to accommodate all types of aircraft, it is essential to strike a balance between minimising inventory costs and ensuring the availability of vital components. The area of operational planning is another where fleet diversity has an impact. Different types of aircraft have varying fuel requirements, range capacities, and runway specifications. These and other factors are considered when planning flights, particularly when selecting suitable airports or figuring out how far an aircraft can travel between refuelling stops. Additionally, it is essential to match customer expectations with aircraft availability. Charter customers frequently have particular requirements, such as needing an aircraft with a specific range or cabin size. It can be challenging to balance these expectations with maximising fleet utilisation. It calls for open lines of communication between the sales team, who deals with customers, and the operations team, who is aware of the aircraft's status and capabilities. While running a diverse fleet presents some difficulties, it also offers flexibility. With a variety of aircraft, the charter company can serve a wide range of customers, from those looking for a quick, inexpensive trip to those needing the comforts of a big jet for long flights. Overseeing operations involving different © STADIO (Pty) Ltd Fundamentals of Aviation Management AVM152 139 types of aircraft in the charter aviation industry is a complex task. Understanding the particular characteristics and needs of each aircraft in the fleet, ensuring proper maintenance and training, streamlining operational planning, and coordinating with customer needs are all important, all while keeping an eye on the bottom line. The first step towards effective management in this dynamic environment for a new manager is to recognise these subtleties. Prescribed reading Read page 127-133 of your prescribed book before continuing. 5.6 MANAGING AIRCRAFT OPERATIONS IN TERMS OF SUPPLY AND MAINTENANCE In the fast-paced world of aviation, particularly within the charter environment, an entry-level aviation manager focuses primarily on the operational aspect of aircraft – that is, ensuring that the planes are where they need to be, when they need to be there, and are ready to take off. This implies that the aircraft's design complexities and manufacturing processes may seem somewhat removed from everyday concerns. However, this viewpoint may be somewhat limited. Consider the following scenario: you manage charter operations, and a particular aircraft model in your fleet has recurring technical issues. This may prompt meetings with aircraft suppliers or manufacturers to determine the underlying cause, or to negotiate replacement or upgrade terms. At this point, the distinction between aircraft operation, design, and production begins to blur. Understanding how the aircraft was designed, the reasoning behind certain features, and the supply chain could provide you with leverage in such discussions. While the task of performing hands-on maintenance may not directly fall under the jurisdiction of aviation operational professionals, it is essential that they comprehend maintenance requirements. In a charter environment, the availability of aircraft is paramount. Grounding an aircraft for maintenance results in lost revenue and potential scheduling conflicts. Maintenance is a complex regimen governed by regulatory requirements, safety protocols, and the aircraft's own wear and tear. It is not just about fixing something that is broken. Regular inspections guarantee that the aircraft is in optimal condition for flight. This not only ensures safety but also improves operational efficiency. For © STADIO (Pty) Ltd Fundamentals of Aviation Management AVM152 140 example, routine maintenance can prevent major technical issues that could otherwise ground the aircraft for extended periods, disrupting the charter schedule and negatively impacting profitability. So, while you as an entry-level aviation manager in a charter environment may initially believe that their primary concern is just to make sure that the aircraft fly, there is an entire background of design, production, and maintenance complexities that play a crucial role in ensuring that this occurs smoothly. Even just a basic understanding of how aircraft are designed, manufactured, and maintained can significantly enhance your capacity to manage charter operations efficiently. 5.7 THE ROLE OF ORIGINAL EQUIPMENT MANUFACTURERS An OEM, or Original Equipment Manufacturer, refers to a company that makes a part or subsystem used in another company's end product. For instance, if Company A produces a component that is used in a plane made by Company B, then Company A is the OEM of that specific component. In the aviation industry, when we talk about OEMs, we typically refer to companies that manufacture aircraft, engines, or other essential components. Three main categories of manufacturers play a pivotal role in shaping the entire industry: airframe OEMs, engine OEMs, and component OEMs. Airframe OEMs: These are the big guys who design and manufacture the actual bodies of aircraft - the structures you see flying in the sky. Key players include household names like Boeing and Airbus, followed by others like Embraer, Sukhoi, and potentially COMAC from China in the near future. Understanding their histories and mergers gives you a grasp of how these giants have evolved. For instance, while Boeing absorbed several U.S. airframers to become a dominant force, Airbus came about through European collaborations. These companies face immense financial challenges and heavily rely on updates to existing models and constant workforce adjustments, given the economic fluctuations. They are essentially the master integrators, bringing together various parts to create a whole aircraft. In your charter business, you will likely deal directly or indirectly with these OEMs when acquiring or leasing aircraft. The choice of which manufacturer's aircraft you use can influence your operational costs, the services you can offer, and even the perception of your brand. © STADIO (Pty) Ltd Fundamentals of Aviation Management AVM152 141 Engine OEMs: Think of these as the heart of your aircraft. Engines dictate how far, how efficiently, and how reliably your aircraft can fly. Major companies like GE, Pratt Whitney, Rolls-Royce, and Snecma dominate this space. They take on huge financial risks, especially when developing new technologies and models. Sometimes, these companies even form partnerships to spread out this risk and produce successful engine models. Their engines are not just exclusive to aviation; some also power naval ships and energy plants. For your charter business, engines play a significant role in your operational costs. Maintenance, fuel efficiency, and reliability are paramount. You will often find yourself weighing the costs and benefits of various engine types and their associated maintenance packages. Component OEMs: This category involves all the parts and systems that make aircraft functional and comfortable. We are talking about the likes of landing gears, avionics (the electronic systems inside the plane), power systems, environmental control, interiors, and much more. Certain companies specialise in specific components, such as BF Goodrich and Messier-Dowty with landing gears or Rockwell Collins and Thales with avionics. Some of these components are tailored for specific aircraft types, while others can be found across various aircraft. In a charter environment, the quality and functionality of these components can greatly affect the passenger experience. For example, the quality of inflight entertainment, seating comfort, or even the efficiency of the cabin's environmental control can be a distinguishing factor for customers choosing your charter service. In summary, as an entry-level manager in the charter sector, a grasp of these various OEMs and their contributions is vital. The decisions you make, influenced by these OEMs, can impact everything from operational efficiency and costs to passenger satisfaction and brand reputation. Always remember, in the world of aviation, every detail, no matter how small, plays a role in the larger picture of safe, efficient, and reliable air travel.

Now identify the OEM for each of those components. © STADIO (Pty) Ltd Fundamentals of Aviation Management AVM152 142 5.8 MANAGEMENT OF PROCESSES RELATED TO MAINTENANCE, REPAIR AND OVERHAUL (MRO) SUPPLIERS MRO is the term used in the aviation industry to describe maintaining, repairing, or overhauling aircraft. MRO consists of: Maintenance: Think of this as regular health check-ups for an aircraft. It is all about maintaining the technical soundness of your aircraft. Planes undergo maintenance at regular intervals based on flight hours, which are prescribed by the aircraft manufacturers. Common checks you might have heard of include the A, B, C, and the very comprehensive D-checks, where the entire aircraft undergoes thorough inspection. But, given the operational demands of a charter service, sometimes it is practical to combine aspects of these checks, a strategy called equalised maintenance. This method ensures checks align with your flight schedules, balancing safety with operational efficiency. Repair: Unlike maintenance, repairs are not scheduled. Imagine a sudden cold or fever that hits you unexpectedly; that is what a component failure in an aircraft is like. When a part malfunctions during a flight, it is typically swapped out with a functional counterpart. This swappable component is known as a line replaceable unit (LRU). Once replaced, the aircraft is good to go, with no lengthy tests required. However, not all parts are created equal. Some have a predefined lifespan (hard-time items) while others are used until they fail (oncondition items). For clarity on which parts are essential for a flight, the aircraft manufacturer provides a guide, the minimum equipment list (MEL). If a crucial component fails and it is not on the MEL, your aircraft is grounded, referred to as aircraft on ground (AOG). Overhaul: This is like a comprehensive makeover for aircraft components. Parts are taken apart, inspected, and faulty ones are replaced. Once overhauled, the component is as good as new. Sometimes, based on newer technologies or materials, parts might even get upgraded during an overhaul, following guidelines called service bulletins. If a part was poorly designed from the start and poses a safety risk, the overhaul might be made mandatory, turning the Service Bulletin into an airworthiness directive (AD). © STADIO (Pty) Ltd Fundamentals of Aviation Management AVM152 143 Example The FAA (Federal Aviation Administration), which is the aviation regulatory body of the U.S., along with Boeing, issued ADs concerning the MCAS (Maneuvering Characteristics Augmentation System) on the Boeing 737 Max. This was in response to two tragic accidents involving the aircraft type. Investigations into these accidents pointed towards potential issues with the MCAS, a system designed to enhance the pitch stability of the plane. The issued ADs required Boeing to make specific software updates to the MCAS, along with associated training for pilots. These directives aimed to address the identified issues and ensure the safe operation of the aircraft. Only after these mandated changes and checks were made, and the FAA was satisfied with the safety measures, was the grounding order on the 737 Max lifted. The purpose of these ADs was to restore confidence in the aircraft's safety and prevent future accidents related to the highlighted concerns. In the past, airlines handled their own MRO requirements. However, outsourcing these tasks has become widespread since the 1980s. Due to this, many of the major MRO companies of today, including Lufthansa Technik and Air France Industries, were founded by or are still affiliated with airlines. It is interesting to note that an airline's MRO division can continue to prosper even after airline bankruptcy. The capabilities of an MRO provider are frequently what determine its value. Operators are more likely to choose an MRO if they can provide a full range of services, from simple fixes to intricate overhauls and even the provision of spare parts. This is so that those with broad capabilities can attract more business since airlines prefer to work with just one or a select few MRO providers. Simply put, it is like choosing a one-stop shop for all your needs. Even though these MRO behemoths rule the market, they do not finish every task themselves. For some services, they occasionally rely on other MRO providers, weaving a complicated web of rivalry and cooperation. Additionally, original equipment manufacturers (OEMs), or aircraft manufacturers, have a place in this industry. They want to make sure that their parts, which can be more expensive, are used during maintenance. There are other parts suppliers, referred to as parts manufacturing approval (PMA) providers, who create approved parts that are sometimes easier to obtain and of equal quality to OEM parts. © STADIO (Pty) Ltd Fundamentals of Aviation Management AVM152 144 MRO selections affect operations directly in a charter environment. It is essential to have prompt and effective MRO services, because any downtime reduces the number of charter flights that are available. Furthermore, economies of scale are important in MRO. It is more economical to perform maintenance when there is a lot of it. However, as technology advances, aircraft are becoming more dependable, necessitating less frequent maintenance. The intervals for these MRO activities are usually defined in terms of flight hours. But for specific components, like engines which heat up, or the wings and fuselage that undergo stress, we also consider cycles. A cycle is basically one flight, no matter its duration. For example, think about the repeated stress the landing gear undergoes every time an aircraft lands. So, its MRO is based on the number of landings (cycles), which can then be translated into flight hours based on how long each flight typically lasts in your charter operations. 5.8.1 The South African context In South Africa, what is globally known as MROs are referred to as AMOs, or Aircraft Maintenance Organisations. These AMOs employ AMEs (Aircraft Maintenance Engineers) who are skilled professionals responsible for ensuring that aircraft are in top condition. Regular checks, compliance with safety standards, and technical know-how are all under the purview of AMEs. The SACAA regularly audit AMOs to ensure they adhere to strict safety and operational standards. Think of the SACAA as the guardian of aviation standards in South Africa. Their audits and checks guarantee that every flight taking off is safe and compliant with international norms. 5.8.2 In-house AMO considerations If you are running a charter operation, aircraft availability and reliability are paramount. Downtime means lost revenue. By having your own AMO, you have more control over your maintenance schedule, ensuring quicker turnaround times. It is like having an in-house doctor for immediate health check-ups. Moreover, in-house AMOs can better understand the specific needs and operational nuances of the charter flights, allowing for more tailored and efficient services. Additionally, owning an AMO can be more cost-effective in the long run. Outsourcing maintenance can be expensive and, at times, less flexible. An inhouse AMO can lead to better financial planning and cost savings, contributing directly to the profitability of the charter operation. © STADIO (Pty) Ltd Fundamentals of Aviation Management AVM152 145 Activity Visit a local AMO and ask them to show you around. List ten things that you learnt from your tour. 5.9 MANAGING OPERATIONS WITH AWARENESS OF METEOROLOGICAL AND NAVIGATIONAL ASPECTS Aviation's meteorological aspects are the study and understanding of weather phenomena and how they affect flight operations. It entails being aware of weather patterns, forecasting methods, and how different weather factors (such as wind, temperature, precipitation, and turbulence) affect flight. Meteorological information is used by pilots, flight planners, and aviation managers to optimise flight paths, ensure the safety of flights, and foresee potential weather-related delays. Navigational aspects deal with the methods and equipment used to direct an aircraft from one location to another. Everything from conventional map reading and compass use to cutting-edge GPS, satellite systems, and sophisticated onboard avionics are included. An aircraft's navigation system makes sure it stays on course, avoids hazards, and gets to its destination quickly and safely. Together, these two elements form the basis of aviation, guaranteeing that flights run smoothly, effectively, and on time. It is essential to comprehend the technical side of meteorological (weather-related) and navigational aspects for a number of compelling reasons: Safety: Safety is always the top priority in the aviation industry. Aircraft can be seriously endangered by bad weather conditions like turbulence, thunderstorms, or icing. You can decide on flight paths, altitudes, and even whether to postpone or cancel a flight by understanding meteorological data. It is not just about responding to the weather; it is also about deliberately planning to stay out of it. Operational effectiveness: When planning a flight, the weather is crucial. A journey can be sped up by a tailwind while slowed down by a headwind. Understanding how to interpret meteorological data can be useful for planning flight routes that maximise fuel efficiency and on-time arrivals. © STADIO (Pty) Ltd Fundamentals of Aviation Management AVM152 146 Comfort of the passengers: No one likes a rough ride. Understanding meteorology can make it easier to identify and steer clear of turbulence, giving your passengers a smoother ride. A comfortable passenger is more likely to purchase from the company again. Navigational accuracy: Modern aviation heavily relies on sophisticated navigational systems for accuracy. Understanding these systems makes it possible for aircraft to take the most practical paths while avoiding dangerous or restricted areas. Additionally, it can be useful in emergency situations where other landings or routes may be necessary. Compliance with regulations: When it comes to flight paths, altitudes, and locations—especially when it comes to weather—aviation authorities have strict regulations. You can always stay compliant and prevent potential legal and financial penalties by having a firm grasp of meteorological and navigational knowledge. Cost control: Flight delays, detours, and extended routes brought on by bad weather or navigational mistakes can add significantly to the cost of fuel, crew labour, and ground support services. You can more effectively control operational costs by comprehending and managing these factors. Accurate cost estimation for clients: When you have a solid understanding of navigational principles and are capable of correctly interpreting weather forecasts, you are well-positioned to give clients accurate quotes. This is because many unexpected costs in the charter industry are caused by weather-related delays, detours, or extended flight paths. You can provide quotes that accurately reflect the costs without unanticipated surcharges by anticipating and accounting for these factors in advance. This openness helps you keep your customers' trust while also ensuring the financial stability of your business operations. Your ability to give a precise quote and stick to it can be a huge competitive advantage in a charter environment where clients might be chartering flights for specific events or tight schedules. It shows professionalism and gives your customers more faith in the knowledge and dependability of your business. Crew communication: Pilots and ground personnel depend on precise and current meteorological and navigational information. Being informed in these areas enables you to interact with your team more effectively, ensuring that everyone is on the same page and improving the coordination between management and operations. © STADIO (Pty) Ltd Fundamentals of Aviation Management AVM152 147 Reputation management: You can improve your charter company's reputation by consistently making wise choices that put comfort, safety, and timeliness first. This can be a big benefit in a field where reputation and trust are important. In essence, meteorology and navigation's technical details are not merely confined to the realm of pilots. They are useful instruments in your managerial toolbox to guarantee secure, effective, and comfortable operations. When you apply this knowledge to your managerial style, you not only promote strong, open relationships with your customers but also ensure operational efficiency. And that can make all the difference in the cutthroat world of aviation charters. To make you a more well-rounded manager that stands out from the crowd, you will learn about meteorological and navigational aspects in your SACAA PPL Meteorology and PPL Navigation modules, which are included in the syllabus for AVM152 here (individual components as per SACAA syllabus). © STADIO (Pty) Ltd Fundamentals of Aviation Management AVM152 148 Summary Understanding the nuances of aircraft certification is crucial when stepping into the world of aircraft operations management. Before taking to the skies, every aircraft must pass certain safety and performance requirements set by the aviation authorities. Consider the aircraft as a dynamic production unit rather than just a machine. Every time it takes off, it makes money, ensuring that its operational use is efficiently maximised. There is an economic side to aviation, just like there is in any business. Every choice about whether to purchase, sell, or use an aircraft has financial repercussions. Understanding the nuances of aircraft economics facilitates making decisions that are in line with your operational and monetary objectives. Keep in mind that not all aircraft are created equally when managing operations. Models and sizes vary, which impacts capabilities and potential revenue sources. Although this diversity gives your operations life, it also necessitates close attention to detail to make sure each aircraft type is used to its full potential. You will frequently interact with the area of supply and maintenance, which is an important aspect. On-time logistical support and meticulous maintenance procedures are essential for an aircraft to operate safely over time. It is not just about making sure an aircraft is ready for take-off, but also about anticipating and proactively addressing any potential problems. Original equipment manufacturers (OEMs) will now play a part. These organisations serve as the framework for the parts of your aircraft. They manufacture and supply the components needed to keep your fleet flying. When examining the operations' maintenance, repair, and overhaul (MRO) side, their significance is further underlined. Effective management of these procedures is essential for extending the life of your aircraft and guaranteeing passenger safety. Finally, the natural environment in which flights take place is just as important as the mechanics of aircraft operations. It is not just pilots who need to understand the meteorological and navigational aspects. Your managerial skills will come in handy if you can plan flight operations while taking weather and navigational difficulties into account. © STADIO (Pty) Ltd Fundamentals of Aviation Management AVM152 149 Self-Assessment Questions The purpose of these self-evaluation questions is to see how well you understand and can use key ideas from the topic.
