RE: How to save twin if one engine stops?
Practice, practice, practice.
Almost no one I know practices engine out. The skill of saving the airplane cannot be discovered in real time.
You can go over the methodology a thousand times in your mind and the fingers will not cooperate unless practiced. You don’t even know if your method is correct until you practice.
I set the radio to drop one engine to high idle, go high and practice. I fly until disorientated and bring the idle engine back up. It takes a few flights to teach the fingers and to discover the single engine characteristics of the airplane. In the event that the idle engine does not come back up I dead stick the airplane.
I have several hundred real engine outs and never a crash but have landed in some very strange places.
