Nope, but when your RPMs are high (and engine power output is low), the air stream is driving the propeller rather than the other way around.  The result is that your prop is creating drag rather than thrust.

Hence my question for Arlo on prop AOA. 

[serun]

Other players routinely shut my engine off quite regularly with machine gun bullets and cannon rounds. As this usually has a detrimental effect on my survivability I have never been tempted to INTENTIONALLY shut my engine off myself.   Gunners on bombers are especially guilty of this atrocity.

Gravity has it's limits. It works great till you hit the stops.

[Arlo]

Gravity provides the thrust when your engines are off.

You use "bottom out" to refer to high RPM? Isn't that backwards?

What do you suppose has more drag, low AOA or high AOA?

Why are you presuming my use of "bottomed out" means "high RPM?"

You feather a prop to reduce drag.

Woah.  I know you from The Sig Forum.

Because you questioned why you would speed up. Speeding up would only be a surprise at high RPM.

Feathering reduces drag but the acceleration still comes from gravity.

Note the difference when you feather the prop while parked.

Drag isn't gravity .... gravity isn't drag. 

[FLS]

Drag isn't gravity .... gravity isn't drag. 

That's good start. We'll take it slow. 

[Arlo]

We'll take what slow? You're the one seems prone to take what I post and run in random directions at high speed.

If you are falling while wearing a dress...... that is drag affected by gravity.

It is drag is affected by atmosphere, not gravity. If Earth had no atmosphere then there'd be no drag.

So you are saying you need proper lighting and maybe Frank Sinatra playing in the background? That enough atmosphere?

I'm more of a Deano or Bobby Darin type ..... but no.

How come when I ditch on the water my plane doesn't sink?

The sound of metal and tarmac screeching as you glide into the water is not real?

The relevant torque is from the spiral propwash, you don't need to cut the engine, you can just pull off the power.

People don't realize that, they saw Skye do it so they think it works.  Turning off your engine during a fight is not a very smart thing to do.

Many years ago during the first years of AH, turning off your engine during a turn fight did help and made some plane turn slightly tighter and your engine would instantly be at full power with no start up delay when turning the engine back on.  But that was fixed not long afterwards when the start up delay was added.
