OTHER ERROR MODES
Autopilot failures that prevent any operation are annunciated
across the center of the PFD mode annunciator strip in amber
(yellow) as shown in the examples immediately below.
PFD Autopilot Annunciator (Avidyne top image, Aspen bottom image)
GENERAL OR UNKNOWN FAILURES
Failure Indication:
If the DFC-PFD system recognizes that the autopilot is invalid but
can not decipher the reason, a yellow “AUTOPILOT INOP”
message is displayed along middle of the PFD annunciator strip.
Functionality Lost:
All autopilot functionality will be lost for the duration of this
message display, meaning the autopilot would disconnect or
prevent engagement. It is possible that the autopilot will conduct
an auto-reset which would kick off any engaged autopilot mode
but following a successful reset, all functionality would be
restored and a manual re-command of autopilot modes will be
available.
Recommended Pilot Action:
Immediately transition to hand-flying via the PFD display.
