Let’s assume the current location puts the aircraft 2 hours from the nearest airport, but the destination is 2 1/2 hours away.
Would the pilots hand fly the rest of the way? Are they allowed to fly to their destination, although it’s just an additional 30 minutes? And how difficult would that be (For the sake of the conversation, we can say I’m specifically asking about the 787, but I am generally interested in long distance capable aircraft)? Or is there tons of ways to fix the auto pilot?
In short, what I’m asking is: how difficult it may be for two pilots to manually fly for this long, is it a big enough deal to cut the flight short 30 mins to land elsewhere?
I'm not sure under what rules, and not sure how the auto-pilot fails either.
