Hi guys!
I am flying a baron 55 for my multi commercial add on training. I have a question on feathering the engine.
I understand the concept of feathering and why we do it but my question is: In these multi-engine props, they are different from, say, a piper arrow in that when oil pressure leaves the prop hub it changes the pitch to be more coarse, correct? I believe that if there is a loss of oil pressure then the props will fail to the feather position. Does this mean in this plane a loss of oil pressure will automatically put the prop in feather, without the pilot having to use the prop control to put it into the feather position?
Also- when I am doing my run-ups with my instructor and we have high RPM, he is very adamant about not letting the prop RPM drop very far when we test the feather (put the leaver into the D-tent and then up very quickly) is this because the prop WILL feather if we leave it there too long and this puts terrible stress on the engine?
Thanks so much.
Phil
