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
The autopilot is manually disengaged by pushing the AP DISC Switch, GA 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 DISC or MET Switch (AP DISC Switch also cancels the flashing ‘AP’
annunciation).
Figure 7-28 Manual Autopilot 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 MET Switch.
Automatic disengagement occurs due to:
• System failure
• Inability to compute default flight director modes (FD also disengages automatically)
• Invalid sensor data
