What direction do both wings of propeller spin to form propeller reverse?

• A. Left
• B. Right
• C. Up
• D. Down

Answer: (B)

Rotating direction determines the thrust direction. A propeller moves air along its axis as the blades sweep around. To reverse thrust, the blades must rotate in the opposite sense from normal forward operation. In this context, that opposite sense is described as moving to the right (clockwise when viewed from behind the aircraft), which reverses the airflow to produce reverse thrust. The other options don’t describe a rotation around the propeller axis, so they wouldn’t create a reverse thrust.
