FD MODES
Navigation Mode (GPS, VOR, LOC, or BC)
The Navigation mode acquires and tracks the selected
navigation receiver on the HSI (e.g. GPS, VOR or LOC).
The Flight Director follows GPS roll steering commands
when the HSI is in GPS mode, and creates roll steering
commands from the Selected Course and deviation when
the HSI is in VOR, LOC, or BC modes. The Selected
Course is controlled using the CRS knob.
Note that the selected navigation receiver must have
a valid signal (VOR, LOC) or active GPS course (GPS) in
order for the Flight Director to enter Navigation mode.
The Navigation mode can be used to fly non-precision
GPS and LOC approaches where glideslope tracking is not
required. It also automatically selects Backcourse mode
when the localizer front course is greater than 105 degrees
from the aircraft heading.
