True or False: Propeller reverse spins counterclockwise.

True or False: Propeller reverse spins counterclockwise.

• A. True
• B. False
• C. Not enough information
• D. Irrelevant

Answer: (B)

The important idea is that reverse thrust is achieved by changing the blade pitch, not by changing the direction the propeller spins. In most aircraft, when reverse thrust is engaged, the propeller continues turning in the same direction it was during forward flight; only the angle of the blades is adjusted to push air in the opposite direction and slow the airplane. So saying the reverse spins counterclockwise isn’t a universal rule. The rotation direction depends on the engine/propeller design, while reverse thrust is about blade pitch.
