     When I took flight training with Charlie Kohler I clearly remember that he taught me to pull out the prop (to coarse pitch) to improve gliding capablities when there is an engine failure.  I am wondering if the prop windmilling would provide enough oil pressure to enable changing the prop pitch.   Perhaps if Charlie or others reading this have the answer, I'd love to hear it.
