don't expect the prop to be stationary. It will be windmilling
oh, contrare...
What I've heard is that a stationary prop will cause less drag than a windmilling one, but in order to get the prop really stopped you've got to slow down to something very close to stall speed, usually. That's not something you're going to do with an engine failure, unless you've got steel nerves and plenty altitude to spare.
Firstly, I don't have nerves of steel. Let me make that clear. There was a definite requirement for Changing of the Undies.
My prop stopped completely - probably due to the fact that we had just gone through to full power at the beginning of a go-round, so were indicating 60-65 knots.
From what I noticed, [in between my cursing, hoping there really IS no hell, and thumping my student] we glided better.
Or maybe it was just that time slowed down. Who knows.
