Control Wheel Steering; Disengaging The Autopilot - Garmin G1000 Reference Manual

Control Wheel Steering

During autopilot operation, the aircraft may be hand-
flown without disengaging the autopilot. Pressing and
holding the CWS Button disengages the pitch and roll
servos from the flight control surfaces and allows the
aircraft to be hand-flown. At the same time, the flight
director is synchronized to the aircraft attitude during the
maneuver. The 'AP' annunciation is temporarily replaced
by 'CWS' in white for the duration of CWS maneuvers.
In most scenarios, releasing the CWS Button reengages
the autopilot with a new reference. Refer to the flight
director modes section for CWS behavior in each mode.

Disengaging the Autopilot

Automatic disengagement occurs due to:
• System failure
• Inability to compute default flight director modes
(FD also disengages automatically)
• Invalid sensor data
• Stall warning
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 MET Switch.
Autopilot Automatically Disengaged

The autopilot may be manually disengaged by pushing
the AP DISC or GA Switch or the AP Key on the MFD.
Manual disengagement is indicated by a five-second
flashing yellow 'AP' annunciation and a three-second
autopilot disconnect aural alert. The AP DISC or MET
Switch may be used to cancel the aural alert.
