Autopilot Annunciation
Autopilot status and mode information is displayed in two dedicated
regions on the top edge of the display. Autopilot and flight director
information are only available if the AFI4700 is configured to support
the aircraft’s flight director and autopilot.

Flight Director / Autopilot Modes
Figure 2-6: Autopilot Modes
Flight Director validity is shown in the top left corner as “FD”. This is
annunciated in one of three modes: 1) Green letters indicating FD
coupled, 2) Magenta letters indicating FD decoupled, or 3) Yellow
letters showing “FD FAIL” indicating FD failure.
The EFI does not control the flight director modes, it only displays
what is commanded. Below are the modes that the EFI is capable of,
however not all may be available from the installed flight director.
Consult the manual of the flight director for operation and full mode
descriptions.
