Disruptive schedule ORO.FTL.105(8): Which criteria should be applied to determine a duty as disruptive if there is a time zone difference between the reporting point and the place where the duty finishes?
The criteria to be applied is the reference time e.g. the local time (LT) where the crew member reported for duty.
Example with “Late type” of Disruptive schedule:
LT in A = LT in B + 1 hour.
Day 1: The crew member starts the FDP acclimatised to A. He/she reports at 15:00 (LT-A) and finishes FDP in B at 23:30 (LT-B). It is a ‘Late finish’ because he/she is acclimatised to A, and FDP finishes at 00:30 (LT-A).
Rest in B. After resting in B, which is within two hours’ time difference from A, the crew member gets acclimatised to B.
Day 2: The crew member reports in B at 15:00 (LT-B) and finishes FDP in A at 00:30 (LT-A). It is not a late finish, because he/she is acclimatised to B, and the FDP finishes at 23:30 (LT-B).
