BEARING POINTERS
There are two bearing pointers on the HSI. Bearing pointer #1 is a single line and
displayed in green and bearing pointer #2 is double line and displayed in cyan.
Each bearing pointer indicates the heading to its currently slaved navigation source
with the head indicating the TO heading and the tail indicating the FROM heading.
If the currently slaved source is FMS, the head points towards the next waypoint. If
the currently slaved source is OFF or a VOR in ILS mode, the bearing pointer #1 or
#2 is not displayed.
The currently slaved navigation source for each bearing pointer is displayed beside
an LSK (L6 for bearing pointer #1 and R6 for bearing pointer #2). These
corresponding LSKs also allow for selection of the slaved navigation source.
Selection of a new slaved navigation source for one of the bearing pointers is
accomplished by pressing the LSK corresponding to that bearing pointer, which
cycles to the next available source (rotating through the available sources in a
circular fashion with each successive LSK press).
Depending on the slaved navigation source for bearing pointer #1 and #2, the three
lines of descriptive text display as:
Slaved Navigation Source - FMS
First Line FMS
Second Line Active waypoint identifier
Third Line Distance to active waypoint
Slaved Navigation Source - VOR
First Line VOR
Second Line Tuned VOR frequency
Third Line DME Distance to tuned VOR
Slaved Navigation Source - TACAN
First Line TCN
Second Line Tuned TACAN Channel
Third Line DME Distance to tuned TACAN
