Definition
The Airplane Flight Manual is the FAA-approved document, prepared by the airplane's manufacturer and specific to that individual aircraft by make, model, and serial number, that contains the operating limitations, performance data, normal and emergency procedures, weight and balance information, and systems descriptions required for the safe operation of that airplane. It is required to be on board the aircraft during flight for most certificated airplanes.
Plain English
The official handbook for a specific airplane. It tells the pilot how to operate that aircraft safely, what its limits are, what to do in an emergency, and how it performs under different conditions. It must usually be carried in the airplane.
Context Anchor
Pilots use the AFM during training, preflight planning, and aircraft checkout to confirm approved limits, procedures, speeds, loading, and performance.
Why Pilots Care
Pilots are legally required to follow AFM procedures and limitations; ignoring them can void airworthiness and create serious safety risks.
Intuition Check
Do not think of an AFM as a general flying textbook. It is the approved operating reference for a specific airplane, and its limits and procedures take priority for that airplane.
Example Sentence 1
Before takeoff from the high-elevation airport, the pilot opened the AFM to check the takeoff distance for the current weight, temperature, and runway conditions.
Example Sentence 2
Any modification to the aircraft must be evaluated against the limitations listed in the AFM to keep the airplane airworthy.
