Stick force refers to the force exerted on the control stick or yoke by the pilot to adjust the elevator control surface and, consequently, the aircraft’s pitch attitude. It is the feedback experienced by the pilot when applying input to the elevator control. Stick force characteristics, including the required force for a given pitch change, play a vital role in determining the controllability and stability of the aircraft, influencing pilot workload and overall flight handling qualities. The formula to calculate Stick force as follows:
Where:
- He is the Hinge Moment in Nm,
