2.5.2 Bearing Pointer Source Select Buttons
The Left Button and the Right Button are the Bearing Pointer Nav Source Select
Buttons (Figure 2-7). The Left Button controls the Single-Line Bearing Pointer and
the Right Button controls the Double-Line Bearing Pointer. Each button controls
which nav source is connected to the respective Bearing Pointer.
The Bearing Pointers act like a conventional RMI (Radio Magnetic Indicator); the needle
points to the station. Unlike a conventional RMI, the PFD 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 connected to any of the available navigation sources;
GPS1, VOR1, GPS2, VOR2, ADF1 or ADF2 (depending on configuration), 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 a round-robin
sequence. The currently connected nav source is displayed directly above its
respective button; blank with only the Bearing Pointer icon indicates that no
nav source is selected, and the Bearing Pointer is removed from the display.
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, or the VLOC is tuned to a localizer frequency),
the Bearing Pointer will not be displayed.
