My question is as follows. Suppose you are on final, configured with full flaps for a landing, say just at 500ft. The engine coughs splutters and dies.
You are doing 65 knots. You judge you aren't going to make the field. Yes, I know I should be able to make the field, but that's moot just now. In addition at places like YMMB, some pretty flat approaches get taught in my opinion.
What is to stop you retracting flap to extend your glide?
What is there to stop you? nothing. Reduce drag ....say F20 or there abouts. Course pitch if you can and have a windmilling prop.
