Primary Flight Display Symbols
Flight Director Command Bars
On newer airplanes, the flight directors automatically pop up in the HDG-V/S mode when a go-around is initiated and provide pitch and roll commands to maintain or return to a lateral and vertical profile.
The following occur with either flight director is displayed:
- Bars bias out of view when bank angle exceeds 45°, and return when bank is reduced to less than 40°
- Bars bias out of view when pitch exceeds +25° or -13°, and return when pitch is reduced to less than +22° or -10°
- Bars bias out of view at touchdown in the ROLL OUT mode
- Bars flash (for a limited time) when a reversion occurs or there is a loss of LOC or G/S signal in the LAND mode
