Its been some 15 years since I stopped flying twins, but for Feathers Magraw in my 8500 odd twin hours I several times lost an engine, and I always immediately thought - now I am flying a single. In the many, many sim checks I did, in those engine fail or shutdown circumstances I always briefed the other pilot that we now fly NR as an absolute priority.
Those of us around then will remember the twin engine flameout on a Bristow AS332L just north of Aberdeen on the ILS. He got a restart done and landed safely. We all learned a strong lesson from that. Lets hope today's twin drivers are still thinking the same.
