2.2.2.2. Bearing Pointer Source Select Buttons
The Lower Left Button and the Lower Right Button are the Bearing Pointer Nav Source
Select Buttons (Figure 2-7). The Lower Left Button controls the Single-Line Bearing
Pointer and the Lower 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 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 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.
