Navigation Mode (GPS, VOR, LOC, or BC)
Pressing the NAV Key activates the Navigation
Mode. Navigation Mode acquires and tracks the selected
navigation receiver on the HSI (GPS, VOR or LOC). GPS
roll steering commands are followed 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 (backcourse) Modes.
Turning the CRS Knob moves the Course Pointer and
displays the Selected Course box. The box is displayed
while the knob is turning and disappears three seconds
after the knob stops turning.
Backcourse Mode is automatically selected when the
localizer front course is greater than 105˚ from the aircraft
heading.
NOTE: When making a backcourse approach, set
