EFIS Flight Director/Autopilot
Turning on the AP/FD Mode
The flight director can be turned on from the following menu:
[EFIS] -> [AP/FD] -> [FLTDIR ON/OFF]
The wings that come up when the flight director is enabled will show the aircraft positioning to follow. All
the pilot has to do is keep the triangle in the wings as they move to follow the commanded source. A
change in heading or track will command the wings to bank in the direction to acquire the new heading or
track. A command to climb or descend to a new altitude will cause the wings to move up or down.
The Flight Director Wings are color coded based on the command source. The wing bar color will show
the horizontal steering source and the triangle tip color shows the vertical steering source.

The Autopilot and Flight Director will level the aircraft
at the Minimums Bug and not fly below it. 200 feet
above the Minimums Bug the FD tips will turn Orange
and you will get a MINIMUMS warning on the EFIS

If you are having difficulty getting the AP/FD to
descend on an ILS or LPV check your MINS Bug
altitude!
