System Overview Flight Instruments Integrated Autopilot DISENGAGING THE INTEGRATED AUTOPILOT The Integrated Autopilot is manually disengaged by pushing the disconnect button on the external autopilot unit, or by pressing the autopilot disconnect button on the control stick or yoke. Manual disengagement is indicated by a five-second flashing yellow 'AP' annunciation and an aural alert. Automatic disengagement is indicated by a flashing red 'AP' annunciation and an aural alert. The flashing indication continues until acknowledged by pressing the ENT Key. Automatic disengagement occurs due to: • System failure • Invalid sensor data • Inability to compute default autopilot modes CONTROL WHEEL STEERING (CWS) (OPTIONAL) EIS CNS Interface GPS Navigation Flight Planning Hazard Avoidance Additional Features Integrated Autopilot NOTE: Not all external autopilot units support Control Wheel Steering (CWS). Control Wheel Steering allows the aircraft to be hand-flown without disengaging the Integrated Autopilot. Press and hold the external autopilot unit's CWS Button (if equipped) to temporarily disengage the pitch and roll servos from the flight control surfaces and hand-fly the aircraft. The G3X autopilot control is synchronized to the aircraft attitude during Control Wheel Steering. The green 'AP' annunciation is temporarily replaced by a white 'CW' for the duration of Control Wheel Steering maneuvers. In most scenarios, releasing the CWS Button reengages the Integrated Autopilot with a new reference. Refer to Sections 9.2 (Vertical Modes) and 9.3 (Lateral Modes) for Control Wheel Steering behavior in each mode. G3X AUTOPILOT STATUS BOX Autopilot (AP) status and Integrated Autopilot mode annunciations are displayed on the G3X Autopilot Status Box, located on the PFD. When the external autopilot unit is engaged and the G3X is issuing commands to it, lateral and vertical modes are displayed. When the external autopilot unit is engaged but it is operating in a standalone mode (i.e., not responding to the G3X commands), the Autopilot status (AP) is displayed; however, the lateral/vertical modes are not displayed. 190-01115-00 Rev.
