SECTION 6 – AUTOMATIC
FLIGHT CONTROL
Disengaging the Autopilot
Automatic disengagement occurs due to:
• System failure
• Inability to compute default flight director modes
(FD also disengages automatically)
• Invalid sensor data
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.

The autopilot is manually disengaged by pushing the
AP DISC Switch, GA Switch, MET ARM 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 MET ARM or AP DISC
Switch (AP DISC Switch also cancels the flashing 'AP' an-
nunciation).
