But, 400 RPM (stated by AerocatS2A) for a windmilling prop sounds a little too low. This value leads me to suspect that there is some form of lock in the propeller - to prevent the fine pitch angles that give the high windmilling RPM and consequent enormous drag.
With both Garrett (-10 and -11U) and Pratt (-41, -42, -34, -67 and -114), when the engine stops working, oil pressure is lost/drops very considerably in normal operation, the props will feather over 20-30 seconds due to loss of oil presssure.
This is something you should know instinctively.
When a prop is feathered, it just about always still rotates a little inflight, every configuration is different.
No multi engine aircraft that I know of when the powerplant fails, the prop will move to the fine position ?.
ace from space also said flight-idle for the engine failure simulation on the EMB-120. His was an interesting account and revealed that the aircraft was virtually out of control. How would it have gone if the prop was windmilling?
As a pilot with a META, this is, and how power reduction stops yaw is a part of the VMCA demonstration, done at a safe altitude.
I have never experienced a prop ceased in fine pitch, but FI on either type presents a huge amount of drag, I believe the engine is not driving the propeller in either case, so what is ?.
All the turbine aircraft I have flown will still climb with one engine at FI and the other producing max power above V1 on T/O and inflight.
