SYSTEM STATUS
During power-up, TAWS-B conducts a system test of its alerting capabilities. The system test can also be
manually initiated. A single chime is issued at test completion. TAWS-B system testing is disabled when
ground speed exceeds 30 knots.

TAWS-B continually monitors several system-critical items such as database validity, hardware status, and
GPS status. If the terrain/obstacle database is not available, the voice alert
“TAWS System Failure”
is generated
along with the ‘TAWS FAIL’ alert annunciation.
TAWS-B 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-B Page. The voice alert
“TAWS Not
Available”
is generated. When the GPS signal integrity is restored and the aircraft is within the database
coverage area, the voice alert
“TAWS Available”
is generated.
