Reverse pitch refers to a specific feature in variable pitch or constant speed propellers. This feature allows the blade pitch angle to drop to a negative value. When pilots select reverse pitch, it decreases the angle of the blades. As a result, the thrust generated by the propeller pushes forward, opposing the aircraft’s motion. This capability is beneficial in various situations. It can shorten landing distances and enhance stopping performance during a rejected takeoff. Additionally, when allowed by the Aircraft Flight Manual (AFM), reverse pitch enables the aircraft to move backward on the ground using its own power.
