Bearing Pointers and Information Windows
There are two bearing pointers available, one or two
can be displayed on the HSI. Pressing the PFD softkey
provides access to the BRG1 and BRG2 softkeys. BRG1
pointer is a single cyan (light blue) line with an open ar
-
rowhead at the end. BRG2 pointer is a double cyan (light
blue) line with an open arrowhead at the end. The bear
-
ing pointers never override the CDI. When one or more
bearing pointers are displayed (but not necessarily visible
if there is no data available), a white ring is presented
around the center of the compass rose to visually separate
the bearing pointer(s) from the CDI.
When a bearing pointer is displayed its associated infor
-
mation window is also displayed. The BRG1 information
window is displayed to the lower left of the HSI and in
-
cludes the bearing source (GPS, NAV1, or ADF), a pointer
icon, and the frequency and GPS-derived great circle dis
-
tance (NAV1 and GPS) to the bearing source. The BRG2
information window is displayed to the lower right of the
HSI and includes the bearing source (GPS, NAV2, or ADF),
a pointer icon, and the frequency and GPS-derived great
circle distance (NAV2 and GPS) to the bearing source.
If GPS is the bearing source, the active waypoint identi
-
fier is displayed in lieu of a frequency. If an active waypoint
is not selected, the bearing pointer is removed from the HSI
and “NO DATA” is displayed in the information window.
If the NAV radio is the bearing source and is tuned to an
ILS frequency, the bearing pointer is removed from the HSI
and the frequency is replaced with “ILS”. If the NAV radio
is not receiving the tuned VOR station, the bearing pointer
is removed from the HSI and the frequency displayed in the
information window is replaced with “NO DATA”.
When NAV1 or NAV2 is the selected bearing source,
the frequency is replaced by the station identifier when
the station is in range.
NOTE: ADF and DME radio installation is
optional.
