You, as a skygod, may of course be quite capable of flying such a manoeuvre.
So here we are at the insulting stage.
You need to read the context in which this procedure might be required.
In the air and on the ground I teach lower the nose and attain best glide first and foremost.
But on the ground I also discuss the engine failure and propeller failure possibilities and what you might be best to do under the circumstances.
I was once asked how to balance a propeller which was bolted to the engine.
First of all, take it off the engine... “...not going to happen.”
Then I saw the extent of the bodgery, the daubing of resin, and the fact he had removed one brass leading edge, resined the rotted bits, and riveted the leading edge back on.
I told him he shouldn’t fly it.
If he did fly it, the leading edge on one side was likely to come off, closely followed by the engine, and so I told him how to handle such an emergency.
Primed, I expect that is what saved his life...
He made the front page news with a telling picture.
We can’t prevent all idiots from flying, but at least we can try to save their skins.
