2.2.2.2. Bearing Pointer Nav Source Control
The two outer buttons between the control knobs are the Bearing Pointer Nav Source
Select Buttons (see Figure 2-7). The left-hand button controls BRG1 (the single-line
bearing pointer) and the right-hand button controls BRG2 (the double-line bearing
pointer), and each controls which nav source is coupled to that bearing pointer.
The bearing pointers act like a conventional RMI (Radio Magnetic Indicator): the needle
points to the station. Unlike a conventional RMI, EFD1000 bearing pointers can also
point to the active waypoint of a GPS navigator, whether that is a VOR, NDB, airport,
intersection, or missed approach point.
Each bearing pointer can be coupled to any of the available navigation sources: GPS1,
GPS2, VLOC1, or VLOC2 (depending on conguration), or to none. Each press of the
Bearing Pointer Nav Source Select Button selects the next available nav source, cycling
through all available nav sources and none, in round-robin sequence. The currently
coupled nav source is displayed directly above the Select Button; blank indicates that
no nav source is selected and the bearing pointer will not be displayed.
If the selected nav source is a valid choice, but no usable nav data is being received
(e.g., the VOR station is out of range), the bearing pointer will not be displayed, or the
VLOC is tuned to a localizer frequency.
