Study Notes
Course Goal and Objectives
- The course focuses on understanding aircraft within the civil air transport system
- Students can expect to learn about the historical development of aeronautical engineering
- They will also explore the operational features of airplanes within different categories and understand how these features relate to specific missions
- The course will cover the identification of different airplanes and their manufacturers, including descriptions of their geometric and operational features
- It will delve into the details of various airplane categories and their unique features
- Students will gain the ability to determine the size of an airplane based on its operational features and to visually represent it using those features
Orders of Magnitude
- Orders of magnitude represent the scale or size of something with powers of ten
- In this context, orders of magnitude refer to the scale or size of airplanes
Airplane Operational Features
- Payload refers to the weight an aircraft can transport, a key factor for airline revenue
- Max Take Off Weight (MTOW) is the maximum weight an aircraft can have at liftoff
- Max Landing Weight (MLW) is the maximum weight an aircraft can have when landing
- Max Zero Fuel Weight (MZFW) is the maximum weight an aircraft can have without fuel
- Range represents the maximum distance an aircraft can fly without refueling
- Cruise Altitude is the optimal altitude for efficient flight
- Cruise Speed is the aircraft's speed during cruise flight
- Flight Duration refers to the total time an aircraft can fly
- Takeoff and Landing Distances are the minimum distances required for takeoff and landing safely
- Landing Speed is the speed at which an aircraft touches down
- Thrust and Power are critical for aircraft safety and performance
Airplane Weight
- MTOW: Max Take Off Weight
- MLW: Max Landing Weight
- MZFW: Max Zero Fuel Weight
- TOW: Takeoff Weight
- LW: Landing Weight
- ZFW: Zero Fuel Weight
- OEW: Operating Empty Weight
- MEW: Manufacturer's Empty Weight
- Payload includes passengers, baggage, and cargo
- Operator’s items comprise items for commercial service (seats, catering, crews, water)
- Aircraft weight out of assembly line includes the structure, powerplant, systems, and furnishings
Flight Range
- Flight range refers to the distance an aircraft can fly between takeoff and landing
- Ground distance or surface distance represents the actual distance traveled on the ground
- Flight distance or air distance represents the total distance traveled in the air, accounting for deviations due to air currents and wind conditions
