DISENGAGING THE AUTOPILOT
The Autopilot is manually disengaged by pressing the autopilot disconnect button
on the control stick or yoke or by pressing the AP Key on the GMC 305/307. Manual
disengagement is indicated by a five-second flashing yellow 'AP' annunciation. Cancel
the aural alert by pressing and releasing the AP/CWS Button again.
Automatic disengagement is indicated by a flashing red 'AP' annunciation. Automatic
disengagement occurs due to:
• System failure
• Invalid sensor data
• Inability to compute default autopilot modes
• Detection of a GDU display on the CAN network (when installed as part
of a G3X/G3X Touch system).
