Which action is essential for completing propeller reverse?

• A. Spin the wings left
• B. The CPS move to the outside of the propeller
• C. Maintain center position
• D. Reverse both arms to the rear

Answer: (B)

Engaging propeller reverse hinges on moving the CPS to the outside of the propeller. This specific position activates the reverse thrust mechanism, changing the blade action to push thrust in the opposite direction and ensuring the reverse mode is engaged safely. Without moving the CPS outward, the system stays in forward thrust and the reverse sequence won’t initiate. The other actions don’t trigger reverse: spinning the wings left doesn’t engage the reverse mechanism, keeping the CPS centered maintains forward thrust, and reversing both arms to the rear is not the input that activates reverse.
