having recently crossed the pacific in a 777, I was impressed by all the water down there and the fact that we only had 2 engines, with many cases of one failing in flight
later I heard that 777 pilots do not practise ditching on their simulators, is this correct?
theres been discussion on ditching a modern airliner with worries about the engines digging in on touching the water with some saying the shear pins would allow the engines to break off, it now seems that this wont happen and the ditching must be done tail down
Some of the presumptions to your question are not valid.
The inflight mandatory shutdown statistics make it is extremely unlikely that a ditching will occur over water on a long haul flight.
Shear pins are designed to break before the wing breaks, assuming the plane lands on its engines. If the impact is great enough both may break.
Ditchings are like crashes into a wall in your automobile. It makes little sense to train for all the variations. The training concentrates on avoiding them
