that contribute to a left-turning tendency in propeller driven airplanes. The forces of P-factor‚ torque‚ slipstream‚ and gyroscopic precession all work to create a left-turning tendency during high-power‚ low-airspeed flight. P-Factor is a force from the propeller. It is also known as Asymmetrical Thrust.
