Every GRT EFIS with vertical autopilot software is capable of displaying a Flight Director. Commercial pilots may recognize it as a tool for precise hand-
The concept is simple: Follow the magenta command bars. When the flight director is activated, the yellow horizontal bars and small chevron replace the wing/nose of the attitude indicator. The larger magenta chevron represents the pitch and bank angle required to achieve the heading/course and climb/descent profile entered into the system. Use the flight controls to nest the yellow chevron into the magenta one. If they are aligned, you are right where the computer says you should be. Note that upon activation, any active VOR/ILS needles will be replaced with scales to make room.
In the example above, the flight director command bars are properly aligned and the pilot is on glidepath. In the example below, the magenta command bar is calling for a descending left bank.
To enable the Flight Director feature:
Enable both the Lateral and Vertical autopilot functions in the General Setup menu. The flight director is controlled by the autopilot functions even if you don't have an autopilot.
