NAV Mode
Pushing the NAV button on the FCP alternately selects and clears the navigation mode
and causes the flight director to generate lateral commands to capture and track the
active navigation source (VOR, LOC, FMS).
The displayed navigation source will determine which navigation submode will be in
operation.
NAV Source Selection
The navigation source is selected using the NAV SOURCE knob on the DCP.
LOC or VOR navigation source is determined by the ground station frequency set on
the RTU.
All NAV mode annunciations appear in the lateral field of the FMA: armed modes in
white, and active/captured modes in green. Captures that are inhibited due to invalid
data are annunciated on the PFDs as a red horizontal line through the mode
annunciation.
VOR Navigation Mode
In VOR navigation mode, the flight director generates lateral steering commands to
capture and track the selected VOR radial (inbound or outbound), using the course
displayed on the active navigation source.
When the NAV button is pressed and the active navigation source is VOR1 or VOR2,
the VOR navigation mode is armed. The armed lateral mode field on both PFDs shows
a white VOR1 (or VOR2) annunciation. When the VOR mode is captured, the armed
annunciations are removed and a green VOR1 (or VOR2) annunciation is displayed in
the active lateral mode field on the PFDs.
The CRS1 and CRS2 knobs, located on the FCP, provide the means to select the
desired course on the pilot’s and copilot’s PFD HSI respectively. Pressing the PUSH
DIRECT knob within the CRS knob synchronizes the corresponding course display
and provides a “direct-to” VOR course.
VOR navigation mode is designed to permit tracking over station and allow for course
changes while tracking. When over a VOR station, the system can accept and follow a
course change of up to 90°. Dead reckoning operation (based on memorized heading)
is provided during VOR station passage. A white DR annunciation appears next to the
active VOR mode annunciation during dead reckoning operation.
When captured, VOR navigation mode is cleared automatically by selection of another
lateral mode, by changing the active NAV source, or by loss of the VOR signal. VOR
navigation mode can also be cleared by pressing the NAV button again.

Localizer Navigation Mode
In localizer navigation mode, the flight director provides lateral steering commands to
capture and track the front course localizer from the active navigation source.
Whenever LOC navigation mode arms, a white LOC1 (or LOC2) annunciation is
displayed in the armed lateral mode field on both PFDs. When the LOC mode is
captured, the armed annunciation is removed and a green LOC1 (or LOC2) is
displayed in the active lateral mode field on both PFDs.
When captured, LOC navigation mode is cleared automatically by:
• Selection of another lateral mode,
• Changing the active NAV source, or
• Loss of localizer signal
LOC mode can also be cleared by pressing the NAV button again.
