Which statement about flight duty period endpoints is true?

• A. Begins at Report Time and ends at IN Time
• B. Begins at Takeoff and ends at Landing
• C. Begins at Crew Briefing and ends at In Flight
• D. Begins at Ground Time and ends at Departure

Answer: (A)

Flight duty period endpoints define the full duty window a crew is on for a given flight assignment. The period should start when you’re required to report for duty, capturing all pre-flight tasks, briefing, and preparation, and it should end at a defined release point called In Time, which marks the official end of that duty period after the flight is completed and the crew is no longer on FDP. This makes sense because the purpose of the FDP boundary is to encompass all on-duty responsibilities related to that flight, not just the time spent in the air. Beginning at takeoff and ending at landing would exclude pre-flight and post-flight duties, and starting at crew briefing or ending during flight would either omit portions of duty or cut it short at an inappropriate point.
