Props Driving Piston Engines
In prop aircraft obviously the engine is designed to drive the propeller as opposed to the other way around. As I understand it, windmilling props (props driving engines) are a bad thing. Could someone please explain why with respect to piston engines.
For a flight with proper descent and approach planning I believe this should only occur during the landing phase and for a short time. What are the implications of an aircraft operating with a windmilling prop for extended periods of time?
Examples: - flight training simulated engine failures
- fixed pitch prop aerobatics
Obviously the engine is not going to fail the second the order is reversed, however does it affect engine life and TBO?
