In-flight rest CS FTL.1.205(c) : Is it possible to extend the FDP, if not all pilots get an in-flight rest?
Answer
CS FTL.1.205(c)(1)(ii) specifies that, for the purpose of FDP extension, each crew member needs to have an in-flight rest period.
First example where an extension of the FDP due to in-flight rest is possible:
Pilot 1 and Pilot 2 commence a FDP from A to B (1:30 h sector). When arriving at B, a third pilot (Pilot 3) joins the crew and they fly from B to C (11 h sector).
The length of the flight from B to C allows each crew member on board (pilots 1, 2 & 3) to have the minimum in-flight rest period during cruise phase: 2 consecutive hours for the flight crew members at control during landing and consecutive 90-minute period for the third pilot.
Second example, where an extension of the FDP due to in-flight rest is not possible:
Pilot 1 and Pilot 2 commence a FDP from A to B (7 h sector). When arriving at B, a third pilot (Pilot 3) joins the crew and they fly from B to C (5 h sector).
The length of the flight from B to C does not allow each crew member on board (pilots 1, 2 & 3) to have the minimum in-flight rest period during cruise phase: 2 consecutive hours for the flight crew members at control during landing and consecutive 90-minute period for the third pilot.
