The yaw damper works by sensing any yaw motion and then applying corrective inputs to the aircraft＇s rudder to reduce or eliminate any unwanted yawing. It is particularly useful in minimizing the effects of turbulence or other external disturbances that can cause yawing and make the aircraft harder to control. The yaw damper is an important safety feature that helps to improve the overall stability and control of the aircraft, especially during critical phases of flight such as takeoff and landing.
