The Bearing Pointers indicate only the bearing information provided by their selected
navigation sources. They resemble and perform like traditional Radio Magnetic Indicator
(RMI) needles. Each Bearing Pointer’s head and tail is aligned with the corresponding
bearing/radial value on the compass. The pilot can select a navigation source for each
of the Bearing Pointers from the same VOR and GPS sources available to the CDI or
simply turn o the Bearing Pointer and Source Information.
Each Bearing Pointer is associated with a Lower Left Button or a Lower Right Button,
its source, and Information Block. The Lower Left Button, immediately adjacent to the
CDI Navigation Source Selection Button is associated with and controls the Single-
Line Bearing Pointer. Likewise, the Lower Right Button controls the Double-Line
Bearing Pointer. The Bearing Pointers’ Source Information is shown directly above their
respective Buttons.
Unlike the CDI’s Course Pointer, which can be adjusted by the pilot, no adjustments can
be made to the Bearing Pointers. When a VOR is selected as the source, the arrow of
the needle points to the VOR navaid to which the receiver is tuned. The position of the
Bearing Pointer tail, with respect to the compass, indicates the aircraft’s current position
on the VOR radial. When a GPS source is selected, the Bearing Pointer indicates the
bearing to the active waypoint.
When the Bearing Pointer Source Information is unavailable or invalid, the Bearing
Pointer and its Source Information are removed (Figure 4-77). The Bearing Pointer’s
Source is also source legend slashed with a red line (Figure 4-78).
When a Bearing Pointer is turned OFF, only the Bearing Pointer’s icon is shown.
The Selected Source, the Source Information, and the Bearing Pointer are removed
(Figure 4-79).
