Asymmetric thrust

Asymmetric Thrust

Asymmetric thrust, also known as P-factor, refers to the tendency of an aircraft to yaw or rotate around its vertical axis when one propeller blade produces more thrust than the other due to their different ascending and descending positions. This phenomenon occurs when an aircraft has a climbing attitude and is exposed to relative wind. When the descending propeller blade on the right side of the aircraft produces more thrust than the ascending blade on the left, the aircraft yaws to the left. Conversely, if the propeller rotates counterclockwise, the P-factor force would be to the right. Asymmetric thrust is a key consideration for pilots during takeoff, landing, and climb-out, as it can affect the aircraft’s directional stability and require corrective action. Understanding and managing asymmetric thrust is essential for safe and efficient flight operations.
