FAQ

What is Gearing ratio?
The Gearing ratio is a function of elevator deflection angle, stick length and stick deflection angle and is represented as 𝑮=δe/(𝒍ss) or Gearing ratio=Elevator deflection angle/(Stick Length*Stick deflection angle). The elevator deflection angle is the angle made by the elevator of an aircraft with the horizontal for an applied stick force, Stick length is the length of the control stick (to move the control surface) of an aircraft and Stick deflection angle is the angle made by the control stick (used to move control surface) of an aircraft with the vertical.
How to calculate Gearing ratio?
The Gearing ratio is a function of elevator deflection angle, stick length and stick deflection angle is calculated using Gearing ratio=Elevator deflection angle/(Stick Length*Stick deflection angle). To calculate Gearing ratio, you need Elevator deflection angle e), Stick Length (𝒍s) and Stick deflection angle s). With our tool, you need to enter the respective value for Elevator deflection angle, Stick Length and Stick deflection angle and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
How many ways are there to calculate Gearing ratio?
In this formula, Gearing ratio uses Elevator deflection angle, Stick Length and Stick deflection angle. We can use 2 other way(s) to calculate the same, which is/are as follows -
  • Gearing ratio=Stick Force/Hinge moment
  • Gearing ratio=Stick Force/(Hinge moment coefficient*0.5*Density*(Velocity^2)*Elevator area*Elevator chord)
