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.
