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.

Table 6-10 TERRAIN-SVS System Test Status Annunciations
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 the GPS signal is re-established and the aircraft
is within the database coverage area, the aural message “Terrain System Available” is generated.
