HSI ANNUNCIATIONS
NOTE:
Some or all HSI annunciations may appear in the four quadrants of
the G3X HSI depending on the external navigator(s) configured (i.e., SL30
Nav/Comm Transceiver and/or the GTN or GNS Series Units).

BEARING POINTERS AND INFORMATION WINDOWS
Two bearing pointers and associated information can be displayed on the HSI for
NAV (VOR, Localizer) and GPS sources as well as nearest airports. The bearing pointers
are light blue and are single-line (Bearing Pointer 1) or double-line (Bearing Pointer
2). A pointer symbol is shown in the information windows to indicate the navigation
source. The bearing pointers never override the CDI and are visually separated from the
CDI by a white ring (shown when the bearing pointers are selected but not necessarily
visible due to data unavailability).
