Disengagement - Garmin G1000:Socata Pilot's Manual

DISENGAGEMENT

Pressing the AP Key does not disengage the yaw damper.
NOTE:
The autopilot may be manually disengaged by pushing the AP DISC, GA, or MEPT ARM Switch, or the
AP Key on the AFCS Control Unit. Manual disengagement is indicated by a five-second flashing yellow 'AP'
annunciation and a three-second autopilot disconnect aural alert. The AP DISC or MEPT ARM Switch may be
used to cancel the aural alert.
The YD Key, MEYT and AP DISC Switches can be used to disengage the yaw damper (the autopilot, if
engaged, also disengages when the AP DISC Switch is pressed). The 'YD' and 'AP' annunciations turn yellow
and flash for 5 seconds upon disengagement.
Automatic autopilot disengagement is indicated by a flashing red and white 'AP' annunciation and by the
autopilot disconnect aural alert, which continue until acknowledged by pushing the AP DISC or MEPT ARM
Switch. Automatic autopilot disengagement occurs due to:
• System failure
• Invalid sensor data
• Roll Trim input
Yaw damper disengagement is indicated by a five-second flashing yellow 'YD' annunciation. Automatic yaw
damper disengagement occurs when autopilot disengagement is caused by failure in a parameter also affecting
the yaw damper. This means the yaw damper can remain operational in some cases where the autopilot
automatically disengages. A localized failure in the yaw damper system or invalid sensor data also cause yaw
damper disengagement.
