Bearing Pointers - Honeywell BENDIXKing APEX EDGE Series Pilot's Manual

Honeywell Bendix/King KFD 840 Primary Flight Display
Lateral (and vertical) deviation scales are not the same for all GPS
units. To determine the course widths for each mode refer to the
manual for the GPS that is installed in each particular aircraft.
For deviation values outside the limits of the scale, the deviation
pointer parks at the end of the scale closer to the deviation value.
When lateral deviation is invalid the deviation needle is replaced with
a red X.

Figure 7-6 Bearing Pointers
Two green bearing pointers that point to the selected NAV source
are displayed. The source is either VOR or GPS. When VOR is
selected, the pointer indicates the relative bearing to the selected
NAV facility. When GPS is the source, the pointer points to the active
waypoint in the flight plan.
