Back to: "F"feathering propeller
- Definição1
- A propeller whose the blades can be moved to an extremely high pitch angle of approximately 90º so they face directly into the airstream and produce no aerodynamic forces. If an engine fails in flight, the aerodynamic forces acting on the propeller will cause it to continue to turn, or windmil.

- Nota adicional1
- Feathering propellers are intended to feather from all flight conditions, taking into account expected wear and leakage. Any feathering and unfeathering limitations must be documented in the appropriate manuals [F2].
- Nota adicional2
- A windmilling propeller produces enough drag on a multiengine aircraft to cause extreme control difficulties, and it can easily lead to a crash. To decrease the drag, the propeller blades can be feathered. Because a feathered propeller does not turn the engine, a damaged engine is prevented form destroying itself. [F3]
