It is better to avoid turns into a dead engine - on all twin engine airplanes.
Olasek, could you please explain why you hold this opinion? I would say that provided the speed is above the critical speed pertaining for the thrust of the good engine and assuming that the rudder force is trimmed, the flight controls (and any competent pilot) should be capable of rolling into and out of a turn in either direction. I have demonstrated this on numerous occasions during multi-engine asymmetric training.
Furthermore, I don't recall ever having seen this restriction mentioned in any Airplane Flight Manual that I have studied.
I'm not trying to score points: I would genuinely be interested to learn where and when this particular piece of pilot's 'folklore' originated.
Thanks!
