The FDP is the period from reporting for duty until the engines are turned off on the last sector. Which term is this?

• A. Flight Duty Period
• B. Duty Period
• C. Standby
• D. Flight Time

Answer: (A)

Flight Duty Period is the time from when crew report for duty until the engines are shut down after the last sector. This defines the on‑duty window for flight crew, covering pre-flight duties, the flight segments themselves, and post-flight tasks. It’s specifically tied to flight operations, so it’s distinct from Standby (being available but not actively operating), Flight Time (the actual time the aircraft is airborne), and a general Duty Period (which isn’t necessarily tied to flight activities). The description in the question matches this on‑duty window precisely, making it the best choice. In practice, the FDP length influences rest requirements and fatigue management under regulations.
