I am not a "expert" but the auto-pilot of A320/A330/A340 can cope with an
engine shutdown even just after take-off when the auto-pilot is engaged.
It is one of the best Airbus security system [from Airbus press] I don't
know if Boeing or MD Douglas airliners have such a thing. IMO it is a very
good safety system, but the problem is that the auto-pilot do not give
enough feedback to pilots, the RMP drop is not enough, I would prefer a
aural warning too.
