A Flight Duty Period begins and ends at which times?

• A. Begins at "Report Time" and ends at "IN Time"
• B. Begins at "Takeoff" and ends at "Landing"
• C. Begins at "Briefing" and ends at "Ground time"
• D. Begins at "Crew Arrival" and ends at "Crew Return"

Answer: (A)

Flight Duty Period reflects the entire window the crew is assigned to operate and support a flight, from when they report for duty to when they are released from duty. It starts at Report Time, when crew check in and are ready for duty, and it ends at In Time, when they are released from FDP duties. This encompasses preflight preparation, the actual flight, and post-flight duties up to release.

Starting at takeoff would omit the preflight tasks and the prep time, which are included in FDP. Ending at landing would miss post-flight duties and the formal release time. The other pairings don’t align with how FDP boundaries are defined in crew scheduling and regulatory compliance.
