Going back to basics..

Cheers.

...strange.... ...!

OK for me....tells you everything you need to know about Blue Knobs...

....and Propeller Controls... ...!

Paul...G-BPLF... 8-)...!

Do a general search for "Propeller Controls"......!

I always use the Prop Control on my Trusty Default Beech Baron 58...and note the effects on the dials...good practice......!

Thanks again Fozz. I did a search and found your original posted site.

Now I think I understand.
It's Magic.

Brett.. Let me see if I've got this right ( I probably haven't!)

The throttle controls the power and therefore rpm of the engine.
The propeller control controls the RPM of the prop.
The prop sorts out it's own angle of attack (blade pitch.)

Doesn't that kind of surgest that the engine is not directly connected to the prop? If that's the case is there some sort of hydrolic arrangement similar to a torque converter on an automatic car, or have I missed the point yet again.

Best.

Yeah.. you're still kinda confused..

[Zaphod]

Wow Brett, that really is a master class.
I think I'll print it and study at my leasure.
It would have been fun if it was Magic though

Thanks to all who replied.

Best.

Zaphod.

One thing I should have added (and I will if the discussion warrants), is that during that climb and then level cruise, the prop (and engine)RPMs will stay at 2700 ... even if you pulled the throttle back during the climb.. the RPMs would stay at 2700..
