I was wondering why airliners use a B777-200ER for flights from MNL to AMS. This is an ETOPS flight on the HAMI route which makes it " dangerous" flight if one engine fails. Why won't they use a B747-400 instead? It has 4 engines a higher capacity, sure its less fuel efficient but doesnt they payload cover it enough?
Or is the 747 restricted due to N-1 or N-2 (i have no clue which situation they must plan for) at DP2 (Near DOREX) in the himalaya?
I know the 777-200ER is restricted due to the DP2 on the Hami route.
Im looking forward to all the suggestions/answers
