YAW DAMPER

The yaw damper provides stability augmentation and turn coordination for the
airplane yaw axis via two linear actuators, in series with the rudder control system.
The yaw damper function will automatically engage on the ground, within 3 seconds
after successful completion of AFCS power-up test. As with the autopilot, the yaw
damper operates in an active/standby configuration. When engaged, the active yaw
damper will center both linear actuators.
The YD will not automatically engage once the airplane is airborne. The YD button,
located on the guidance panel, may be used to reengage the YD. When YD is engaged,
the associated arrow on the guidance panel is illuminated.
One yaw damper must be engaged for autopilot operation. Autopilot engagement
without YD will occur only when both YDs have failed in flight.
For more information on yaw damper, please refer to Chapter 10, FLIGHT
CONTROLS.
