AUTOMATIC FLIGHT CONTROL SYSTEM
APPROACH (GPS, VAPP, LOC) MODE
Approach Mode is activated when the APR Key is pressed. Approach Mode acquires and tracks the selected
navigation receiver on the HSI (GPS, VOR, or LOC). The mode annunciation corresponding to the selected
navigation receiver (with the exception of VOR, which is annunciated ‘VAPP’ to indicate VOR Approach
Mode) is displayed in the AFCS Status Box. This mode uses the selected navigation receiver deviation and
desired course inputs to fly the approach.
Approach Mode provides greater sensitivity for VOR tracking than Navigation Mode and allows the autopilot
to fly an ILS approach with a glideslope. Glideslope Mode is automatically armed when LOC Approach Mode
is selected.

NOTE: If the NAV radio is tuned to a different VOR while in VOR Navigation Mode, the flight director reverts
to Roll Hold Mode (wings level) and arms VOR Navigation Mode.
If the Course Deviation Indicator (CDI) shows greater than one dot when Navigation or Approach Mode
is selected, the selected mode is automatically armed.

The flight director remains in the active roll mode until entering capture phase, at which point Navigation
or Approach Mode is annunciated as the active roll mode in green.
