2. D. (4) (f) Course Deviation,
Course Pointer with Readout - The course
deviation bar represents the centerline of the selected
navigation or localizer course.
The aircraft symbol
pictorially shows aircraft position in relation to the
displayed deviation.
The course pointer is positioned around the rotating heading
dial in one of two manners:
Course select knob located on the flight guidance controller
for short range NAV (SRN) sources (i.e., NAV, ILS, MLS).
Long range NAV (LRN) sources automatically select the
desired track data for the active flight plan (i.e., FMS).
A digital readout corresponding to the pointer position is
provided and located to the upper left of the compass rose.
The data is labeled CRS for SRNS and DTRK for FMS. The
pointer, deviation indicator, and digital readouts are green
for SRN sources and cyan for FMS. The center of the course
select knob contains a button labeled SYNC. Selection of the
SYNC button causes the course pointer to align with the bearing
of the selected NAV source causing the deviation bar to center.
The SYNC mode is only operational when the displayed navigation
source is VOR.

Distance Display - The distance display indicates the nautical
miles to the selected DME station or FMS waypoint. The
distance display is located to the upper right of the compass
arc. The data is labeled DME (Figure 217) for SRN sources and
NM (Figure 218) for FMS. The digital display color is
consistent with the course select pointer (i.e., green for SRNS
and cyan for FMS). DME hold is indicated with an amber H
displayed adjacent to the distance readout.
NAV Source Annunciations - Annunciation of the navigation
source is displayed in the upper right-hand corner of the
compass rose directly above the distance readout. The crew has
the ability to select all navigation sources available in any
given installation through the display controller as shown in
Figure 207 (note the PFD displayed NAV source is also the COMP
mode displayed NAV source). The labels are normally displayed
in white. When the pilot and copilot NAV sources are the same,
they are annunciated on both displays in amber.
