RE: How to save twin if one engine stops?
I have had several hundred engine outs and never any damage. Engines will stop running at awkward times.
The most important aspect of a dead engine is to treat it like a dead stick. The mind says to throttle up and that is absolutely backwards.
The next most important aspect is to practice engine out under non-emergency conditions. You CAN NOT learn to fly engine out during a real emergency.
Set a switch on the radio to shut one engine back to idle. Throw the switch and fly until disorientated and then throw the switch back. You will get lots of emergency engine out practice with minimum danger to the airplane.
