Gearing Ratio Given By Elevator Deflection Angle Calculator

The gearing ratio in flight mechanics represents the relationship between the movement or deflection of a control surface on an aircraft and the corresponding input from the pilot via the control stick or yoke. Mathematically, it is expressed as the ratio of the control surface deflection  to the control input . A higher gearing ratio indicates that a smaller pilot input results in a larger control surface movement, impacting the overall control dynamics of the aircraft. The formula to calculate gearing ratio as follows:

Where:

  • G is the Gearing ratio in 1/m.
