When does flight time end for an army aviator?

• A. Wheels off the ground
• B. Engine stopped or crew swap
• C. Landing
• D. Mission complete

Answer: (B)

Flight time ends when the engine is stopped or a crew swap occurs. This marks the point at which the aircraft is no longer under the flying aviator’s control and the aircraft is no longer in active flight for that crew member. Starting time is wheels off the ground, so that event clearly marks the beginning. Landing isn’t the formal end because the log account is tied to the engine being shut down; after landing the engine is typically still running for postflight checks, and a crew swap would immediately end the current aviator’s log for that sortie. Mission complete is too vague and doesn’t define a concrete, auditable moment in the flight log.
