Well I guess the inputs in a twin are no bigger than loosing two on the same side on a 4 holer
(in the ol'days on the 146, we had an instructor who loved chopping 2 engines right or left side (in the sim), after takeoff, speed in the V2 +10 range. As the beast is not climbing with 4, picture the performance with 2 donkeys lost on one side
).
Our beloved design engineers have always (well almost...) given aircraft big enough rudder to counteract such problems.
Err, 411A, regarding the yaw damper, I doubt it would have been of any help, even had it been switched on. Quite the opposite. Think about the reason it had to be off during T/O & LD...
