Selection of a VHF NAV source in the active block is carried out by accessing the PFD MENU, selecting NAV-SRC, and rotating the inner DATA knob on the DCP to the desired navigation source.
VHF navigation data may be set as the preset navigation source by rotating the DCP DATA knob until VOR or LOC is displayed, and the PUSH SELECT button is pushed. The preset navigation source data may be moved to the active block by pressing the NAV SRC button on the DCP. The previous active data is moved to the preset block.

When VOR/LOC is selected as the active source, the active block displays:
.
Active navigation source title;
.
Course readout;
.
Station identification;
.
Time-to-go – from DME; and
.
Distance display – to VOR station, or distance to runway (LOC).
Text color in the active block is also dependent on the navigation source selected. On-side VOR/LOC data is green, while cross-side data is shown in yellow.
When VOR/LOC is selected in the preset navigation (PRESET NAV) block, the following data is presented:
.
Navigation source (SRC): VOR or LOC, shown in cyan;
.
Preset course (CRS): shown in cyan; and
.
Preset frequency (FREQ): shown in green.

Course Selection and Tracking
The flight control panel (FCP) course knobs (CRS 1, CRS 2) are used to set the course selector when VOR or LOC is the active navigation source. Selection of the PUSH DIRECT button, located in the center of each CRS knob, sets the course direct to the tuned VOR station.
The lateral deviation bar forms the center of the course pointer, and moves along a white deviation scale, shown perpendicular to the course pointer.
The course pointer, deviation bar and To/From indicator are shown in green when on-side VOR/LOC data is displayed, or in yellow when cross-side data is selected.

LOC/GS Deviation
A lateral deviation scale is shown above the compass rose when a localizer (including back course) is selected as the preselect or active VHF navigation source. LOC deviation is displayed as a diamond-shaped pointer against the deviation scale. The pointer is removed from view when LOC is no longer the active NAV source.
A vertical deviation scale is shown on the right side of the attitude display when localizer is the preselect or active VHF navigation source. GS vertical deviation is displayed as a diamond-shaped pointer against the analog scale. The deviation pointer is removed from view when back course approach is selected.
