when does p factor cause the airplane to yaw to the left
P-factor
is an aerodynamic phenomenon experienced by a moving propeller,[1] that is responsible for the asymmetrical relocation of the propeller's center of thrust when an aircraft is at a high angle of attack. This shift in the location of the center of thrust will exert a yawing moment on the aircraft, causing it to yaw slightly to one side. A rudder input is required to counteract the yawing tendency
