YAW DAMPER

Yaw Damper is available in aircraft that have an autopilot servo
NOTE:
installed on the yaw axis.
The Yaw Damper reduces Dutch roll tendencies, coordinates turns, and provides a
steady force to help maintain directional trim. It can operate independently of the
autopilot and may be used during normal hand-flown maneuvers.
The Yaw Damper is engaged by pressing the YD key. It will also be engaged by pressing
the AP key to turn on the autopilot. If the autopilot is disengaged using the AP key or
the MET switch the Yaw Damper will remain engaged and can be separately turned off by
pressing the YD key. If the autopilot is disengaged using the AP DISC / TRIM INT button
on the control yoke/stick the Yaw Damper will also be disengaged.
In an installation that does not have a Yaw Damper servo, pressing
NOTE:
the YD Key will result in a DISABLD KEY message on the GMC 605.
When the Yaw Damper is engaged it is annunciated on the GMC 605 with the YD LED
illuminated in green. On the GI 285 the YD annunciation is illuminated green.
