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.
