What does "flight time" refer to in pilot requirements?

"Flight time" in the context of pilot requirements is defined as the total time from when an aircraft moves under its own power until it comes to a complete stop at the end of the flight. This definition is essential because it encompasses not just the time the aircraft is airborne, but also includes the taxiing phases both before takeoff and after landing. Understanding this distinction is crucial for pilots, particularly when logging hours for licensing, currency, or experience requirements.

While the other options may describe aspects of time related to flight, they do not accurately capture the full scope of what "flight time" entails as defined by regulations. For instance, focusing solely on the time from takeoff to touchdown would exclude important preparatory and concluding actions that are part of the pilot's operational responsibility. Thus, understanding the complete definition helps pilots accurately track their experience and adhere to regulatory standards.
