Was having a discussion with one of our Captains today and he asked me this
question.
Night, engines failed, no radio altimeter obviously, what QNH would you set?
Depends where you are when the engines fail, but why not ask ATC if they can give you the QNH, if thats not posible due to a remote location then use the last known QNH.
If over the sea; then when you think you are close to sea level, lights on and use the mark one eye ball, if over land when you switch on the lights and you dont like what you see then turn them off and hope for the best.
