SYSTEM OVERVIEW FLIGHT INSTRUMENTS EIS AUDIO PANEL & CNS FLIGHT MANAGEMENT AVOIDANCE Automatic Flight Control System 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. Control Wheel Steering Figure 7-27 CWS Annunciation 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 twosecond 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 Figure 7-29 Automatic Autopilot Disengagement HAZARD AFCS ADDITIONAL FEATURES APPENDICES INDEX 190-01263-01 Rev.
