Abstract:
Methods and systems for feathering a propeller are described herein. A solenoid is configured to cause a propeller to feather when the solenoid is energized. An electronic controller is connected to the solenoid through a first electrical connection for energizing the solenoid to feather the propeller. A secondary mechanism is connected to the solenoid through a second electrical connection for energizing the solenoid to feather the propeller. The second electrical connection is independent from the first electrical connection.
