when does p factor cause the airplane to yaw to the left
is an aerodynamic phenomenon experienced by a moving propeller , 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
