SYSTEM STATUS
During G1000 power-up, TAWS conducts a self-test of its aural and visual annunciations. The system test can
also be manually initiated. An aural alert is issued at test completion. TAWS System Testing is disabled when
ground speed exceeds 30 knots.

TAWS 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 “TAWS System Failure” is generated
along with the ‘TAWS FAIL’ alert annunciation.
TAWS 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
‘TAWS N/A’ is generated in the annunciation window and on the TAWS Page. The aural message “TAWS Not
Available” is generated. When the GPS signal is re-established and the aircraft is within the database coverage
area, the aural message “TAWS Available” is generated.
