SYSTEM STATUS
During power-up, Terrain-SVS conducts a self-test of its visual annunciations and voice alerts. An voice 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 system issues the voice alert “Terrain System
Failure” 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 voice alert “Terrain
System Not Available” is generated. When sufficient GPS signal is returns and the aircraft is within the
database coverage area, the voice alert “Terrain System Available” is generated.
