Where I fly, on longhaul flights, the FDP starts 1.5 hrs before scheduled departure and ends at chocks in - hence the maximum flight time of 16.5, maybe 17 if the operator has different provisions.
Thats not not enough to do a proper ULR flight, like eg. LHR-PER.
From what I’ve seen, other jurisdictions have special provisions for ULR flights, on case by case basis - i.e. certain max FDP is granted for a particular route, taking into account individual arrangements, such as departure time, rest periods, crew requirements etc. Is there anything similar in EASA?
