Stick length in flight mechanics designates the physical dimension of the control stick or yoke in an aircraft cockpit. This parameter directly impacts the lever arm available to the pilot for making control inputs. The length of the stick is a critical design consideration, influencing the mechanical advantage and the pilot’s ability to achieve precise and controlled movements. Designers balance stick length to optimize pilot comfort while achieving the desired handling characteristics of the aircraft. The formula to calculate stick length as follows:
Where:
- He is the Hinge moment in Nm,
- δe​ is the elevator deflection angle in radian,
- F is the Stick force in N,
- δs is the Stick Deflection Angle in radian.
