Hey guys, As I'm preparing for my commercial oral I'm going over the constant speed prop. Do you agree with this illustration (found online) of ground idle and take off blade angles? I was expecting the take off blade angle to basically look like the ground idle. My reasoning is that when taking off, the propeller control is pushed all the way in which results in the smallest blade angle allowing for max RPM. If so when pulling back the propeller control to idle, I would expect a much flatter blade angle. Instead this illustration shows a vertical blade (small angle) for ground idle. Word for word the PIM says: "When oil pressure is relieved, centrifugal force, assisted by an internal spring twists the blades toward low pitch (high RPM).
