SYSTEM STATUS
During power-up, Terrain-SVS conducts a self-test of its aural and visual annunciations. An aural alert is
issued at test completion.
Terrain-SVS continually monitors several system-critical items such as database validity, hardware status, and
GPS status. If the terrain/obstacle database is not available, the aural message
“Terrain System Failure”
is
generated along with the ‘TER FAIL’ alert annunciation.
Terrain-SVS requires a 3-D GPS navigation solution along with specific vertical accuracy minimums. Should
the navigation solution become degraded or if the aircraft is out of the database coverage area, the annunciation
‘TER N/A’ is generated in the annunciation window and on the Terrain-SVS Page. The aural message
“Terrain
System Not Available”
is generated. When sufficient GPS signal is returns and the aircraft is within the
database coverage area, the aural message “
Terrain System Available
” is generated.
