The Captain has authority over the assigned Flight Crewmembers from:

• A. The moment they report for duty
• B. The time they report for duty until the termination of the flight
• C. From cockpit entry to the end of the flight
• D. The time they report for duty until the aircraft is parked at the gate

Answer: (B)

Authority over assigned Flight Crewmembers starts when they report for duty and continues through the entire flight for which they are assigned. The Captain must be able to direct crewmembers and make operational decisions for the duration of that flight, including preflight checks, taxi, takeoff, in-flight duties, landing, and post-flight tasks needed to conclude the flight. This is why the end point is the termination of the flight—the official moment the flight is completed and the crew’s duties for that mission are finished. Beginning at cockpit entry would miss the preflight duties under the Captain’s purview, and stopping at the aircraft being parked at the gate would extend authority beyond the flight’s formal termination. The authority ends when the flight is terminated and the crew is released from that flight.
