Study Notes
Flight Safety Definition
- Flight safety is the condition of being safe from undergoing or causing hurt, injury, or loss.
- According to ICAO, flight safety is the state in which risks associated with aviation activities are reduced and controlled to an acceptable level.
- FAR defines safety as the freedom from conditions that can cause death, injury, occupational illness, damage to or loss of equipment or property, or damage to the environment.
Flight Safety Factors
- There are three interdependent factors that contribute to flight safety: person, environment, and machine.
- These factors act in series, not parallel, meaning failure of a single link is sufficient for an accident to happen.
- A pilot's error can put the best aircraft in jeopardy, and the best pilot cannot compensate for a serious failure in an aircraft.
The Machine
- The design of the machine must consider the environment in all forms, such as air pressure and temperature, gusts, icing, and lightning protection, air traffic communications, etc.
- The machine is operated by persons, in flight and on the ground, and the relationship between the person and machine is important.
Airworthiness Definition
- Airworthiness is the possession of the necessary requirements for flying in safe conditions, within allowable limits.
- The necessary requirements include design rules, people who make the machine, oversight from design to construction and operations, and responsible organizations for manufacturers and air operators.
- The airworthiness standards evolve with time, and often accident analysis leads to additional rules.
Airworthiness Requirements
- Strength of structures, flight qualities, and performance are essential requirements for airworthiness.
- Maintenance manual, flight manual, necessary tests, criteria for good design practice, system fatigue, and flutter are also critical aspects of airworthiness.
Breaking the Limits
- Examples of breaking the limits of airworthiness include:
- Overweight takeoff.
- Aerobatic maneuvers by aircraft designed for non-aerobatic operations.
- Flights in icing conditions without suitable protections.
- Exceeding speed limits.
Learn about flight safety and airworthiness in the context of aviation regulations. Understand different definitions of safety provided by ICAO and FAR.
