Automatic Disengagement

Automatic disengagement typically occurs due to a failure. Automatic disengagement is annunciated by a flashing ‘AP’, alternating red on white and white on red in the Autopilot Status field. Also, the autopilot disconnect aural alert will be heard. Both the annunciation and the aural alert will continue until acknowledged by pressing the AP DISC button or the MET switch.

Manual Disengagement

The autopilot may also be manually disengaged by pressing the AP DISC button, the GO AROUND button, or by pressing the AP Key on the MFD. Manual disengagement is annunciated by a five-second flashing yellow ‘AP’ in the Autopilot Status field and by a two- second Autopilot disconnect aural alert.

Control Wheel Steering

Pressing and holding the CWS button disengages the servos from the flight control surfaces and allows manual manuevering of the aircraft. 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 until the CWS button is released.

6.4LOSS OF DATA

In general, a flashing yellow mode annunciation indicates either the loss of sensor data (AHRS, ADC, or GIA) or loss of navigation data (VOR, LOC, or GPS) required to compute commands.

When such a loss occurs, the system automatically reverts to the default mode for the affected axis (wings level ROL for roll axis, PIT for pitch axis). The flashing annunciation stops when the pilot presses the affected mode button or selects another mode for the axis. If no pilot action is taken, the flashing annunciation stops after ten seconds.
