3.2.6 HSI FAILURE ANNUNCIATIONS
External sensor systems failures are annunciated in black text inside
a red box. Up to three different failures are displayed:
HDG Loss of Compass or Heading Valid. The digital heading is
removed from the display, but the compass card remains
on the display. See Special Considerations section.
NAV Loss of Course Deviation Valid. The deviation bar and
or VOR scale are removed from the display. The to/from arrow is
or ILS also removed from the display if the navigation source is
NAV or VOR.
GS Loss of Glideslope Valid during ILS Approach mode. The
glideslope scale and pointer are removed from the display.
An additional annunciation of
“ALERT” is provided when an
INS waypoint is approached.
A red “X” annunciation in the
yellow cross-side failure box
indicates that the cross-side
status has not been received
for at least two seconds. All
HSI failure flags flash for four
to six seconds upon initial dis-
play, then become steady
indications.
NOTE: The only cross-side
failure annunciated by a nor-
mal HSI (Integrate mode not
active) is the red “X” indicat-
ing the loss of cross-side
information. With Integrate mode active, an HSI will display the same
cross-side failure information provided by an ADI.
