CESSNA diving from 30 000 feet

Hi everybody,

At 30 000 feet, 0 throttle, I decided to dive for fun.

Then the propeller started to spin and the sound of engine made itself heard.

Realistic?

When you drive a car downhill with the gear engaged and using the engine for braking. Do you hear the engine revving or not?

Thx for your answer, Jan. I didn't catch your drift but thx.

I'm aware this question may sound utterly dumb and devoid of interest for an expert.

I'm not trolling yet. I'm as rookie as can be. I was just surprised that, with Ignition OFF and 0 Throttle, the engin could continue revving.

In the real world it does make slightly different noise when there is no ignition happening. But we don't have a sound recording from the real world yet so it's not that easy to implement

Thanks for your patience, Jan.

So I can safely conclude that it's the force of wind that makes the propeller spin.

I have plenty of stuff to say about what could be done in terms of help and tutorial but it will be for another time.

Have a nice day.
