The Deflection Angle (δ) Of Ailerons on an aircraft is the angle at which these control surfaces are moved to induce a roll motion. The formula for aileron deflection angle is not a single equation but is determined based on aircraft design, control system, and pilot input. Generally, aileron deflection can be represented as:
- δ is the total aileron deflection angle (in degrees or radians).
- δ_pilot represents the pilot’s input, which is the angle the pilot deflects the control yoke or stick to one side to initiate a roll. This is typically provided by the pilot and may vary depending on the desired roll rate.
- δ_automatic accounts for any automatic or computer-controlled deflection of ailerons, which can be used to assist the pilot in achieving desired roll characteristics or to stabilize the aircraft.
