Thinking about it, I have over 1k hours in my RV. I have no idea what the MP reads when the engine is stopped , simply because I never look at it , and most of the time it is turned off when the engine is off.
2nd I can not even tell you what that gauge reads at ideal. Again it is not something any pilot cares about and I have never considered looking and committing to memory what it reads.
I can tell you where it should be when doing lazies eights to maintain alt and speeds.
I can tell you where it should be when doing verticals.
I can tell you what it almost allays reads at 5500 ft.
I can tell you where to put it form normal cruise down low.
I can tell you where to put it after crossing 500 ft.
I can tell you what it looks like when oil runs down the tube and fills the gauge.
I can tell you what it does when pulling back 200 rpm.
But again I have no idea what it does with a stopped prop, in fact I cant even tell you what the minimum read out is on the gauge that I have looked at 10, 000 times.
And finally it really is not all that easy to make it read correctly with out the engine running.
