Disengaging The Autopilot And Yaw Damper - Garmin G1000 Pilot's Manual

DISENGAGING THE AUTOPILOT AND YAW DAMPER

The autopilot is manually disengaged by pushing the AP DISC Switch, AP TRIM ARM Switch, or the AP Key
on the MFD. Manual disengagement is indicated by a five-second flashing yellow 'AP' annunciation and a two-
second autopilot disconnect aural alert. After manual disengagement, the autopilot disconnect aural alert may
be cancelled by pushing the AP TRIM ARM or AP DISC Switch (AP DISC Switch also cancels the flashing 'AP'
annunciation).
The YD Key or AP DISC Switch can be used to disengage the yaw damper. The 'YD' annunciation turns
yellow and flashes for five seconds upon disengagement.
Automatic autopilot disengagement is indicated by a flashing red 'AP' annunciation and by the autopilot
disconnect aural alert, which continue until acknowledged by pushing the AP DISC or AP TRIM ARM
Switch.
Automatic disengagement occurs due to:
• System failure
• Inability to compute default flight director modes
(FD also disengages automatically)
Automatic yaw damper disengagement occurs when autopilot disengagement is caused by a failure in a
parameter also affecting the yaw damper. This means that the yaw damper can remain operational in some
cases where the autopilot automatically disengages. The yaw damper also disengages upon a localized failure
in the yaw damper system.
