yawdemper
A yaw damper is an automatic control system in an aircraft that automatically applies rudder input to damp yawing motions of the airplane, most notably the Dutch roll. It uses sensors such as yaw rate gyros (and sometimes sideslip or other attitude signals) to detect yaw motion and generates corrective rudder deflections through hydraulic or electric actuators.
In operation, the yaw damper acts as a stabilization augmentation device within the aircraft’s flight control
Purpose and effects include reducing Dutch roll, limiting rudder activity required from the pilot, improving directional
Implementation varies by aircraft. Yaw dampers are common on airliners and many business jets, where they are
