Can FDP be extended in the air?

• A. No, cannot be extended in the air.
• B. Yes, extended in the air to reach the destination.
• C. Yes, extended in the air only for long-haul flights.
• D. Yes, extended in the air but only within 1 hour of destination.

Answer: (B)

The idea here is that the Flight Duty Period (FDP) can be extended in flight when operational needs require continuing to the destination, and doing so stays within regulatory and fatigue-management limits. In practice, if weather, delays, or other factors would force the flight to land short or cancel, the crew may be allowed to push on and complete the trip, as long as the extension fits the airline’s procedures and the crew can still meet required rest and duty-time limits after arrival. That’s why the best choice is that extending in the air to reach the destination is permitted. The other options imply restrictions that don’t reflect how in-flight extensions are handled under safety and regulatory guidelines.
