Re: Prop Control
If you ever lose power on your IO-540, you WILL want to get as close to
feather on your prop pitch controller as possible! That big prop is a
VERY efficient speed brake!!! (Don't ask me how I know this.) I
suggest you set up you linkage to get full throw capability!

Hi All,
With the counterweighted blade MT Propeller, when you loss oil pressure, the
propeller goes to coarse pitch. But you probably already knew that.

Paul is right. We once had access to a Cherokee 180 with a VP prop and
tested the rate of descent with the engine idling and the prop full coarse.
Instead of about 1000 fpm we reduced the rate to about 750.
There are two problems, of course. If you practice forced landings with a
prop windmilling in fine pitch and then execute it for real at a
substantially different rate of descent, how would that assist in hitting
the mark? Secondly, we also found that the largest effect on the rate of
descent occurred within the first inch or so off the fine-pitch mark. After
that there was no substantial gain.
So, it appears that if your restricted pitch travel doesn't compromise
safety, leave it where it is.
Nico
