DISENGAGING THE AUTOPILOT
NOTE: When the autopilot is engaged with auto trim enabled, moving the
MET Switch will disengage the AP.
The Autopilot is manually disengaged by pushing the autopilot disconnect button on
the pilot's flight controls or by pressing the AP Key on the GMC control unit. Manual
disengagement is indicated by a five-second flashing yellow 'AP' annunciation and an
aural alert. Cancel the aural alert by pressing and releasing the AP/CWS Button again
(GSA 28 autopilot only).
Automatic disengagement is indicated by a flashing red 'AP' annunciation and
an aural alert. Touch to acknowledge or touch Back to acknowledge. Automatic
disengagement occurs due to:
• System failure
• Invalid sensor data
• Inability to compute default autopilot modes
