4.4.7.8 TAWS Not Available Alert
TAWS requires a 3-D GPS position solution along with specific vertical
accuracy minimums. Should the position 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.
4.4.7.9 TAWS Failure Alert
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 a
‘TAWS FAIL’ annunciation.
4.4.8 TAWS System Status
During 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.
