Which statement best defines Flight Time?

• A. Time from aircraft begins taxi to its clearance
• B. Time from when the aircraft moves under its own power for the purpose of flight and ends when it comes to a rest after landing
• C. Time from doors closed to doors open
• D. Time from engine start to parking brake release

Answer: (B)

Flight time measures how long the airplane is in flight, starting when the aircraft begins moving under its own power for the purpose of flight and ending when it comes to a rest after landing. This definition covers the entire airborne phase—the takeoff roll, climb, cruise, descent, approach, landing roll, and stop after touchdown. It reflects the actual period the aircraft is operating as a flying vehicle, not merely moving on the ground or during cabin procedures. Other options mix in ground movements before takeoff, time spent with doors closed, or ground-time from engine start to parking brake release, which don’t represent the duration the aircraft is in the air or performing flight operations.
