Block time measures what in flight operations?

• A. The elapsed time from pushback to arrival at the gate.
• B. The total time from engine start to shutdown.
• C. The time between taxi-out and takeoff.
• D. The time in the air.

Answer: (A)

Block time is the total elapsed time from when the aircraft begins moving away from the gate (pushback) until it arrives at the next gate. This covers taxi-out, takeoff, the enroute flight, landing, and taxi-in, giving the full duration of that flight segment. It doesn’t start at engine start or end at shutdown, and it isn’t limited to just the airborne portion or only the taxi-out interval.
