System Status - Garmin G1000 Manual

SYSTEM STATUS

During G1000 power-up, TAWS-B conducts a system test of its alerting capabilities. The system test can also
be manually initiated. A voice alert occurs at test completion. TAWS-B System Testing is disabled when ground
speed exceeds 30 knots.

* Annunciation is displayed on the MFD when terrain display is enabled.
Manually testing the TAWS-B System:
1) Select the TAWS-B Page.
2) Press the MENU Key.
3) Select 'Test TAWS System' and press the ENT Key to confirm the selection.
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" occurs 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, and the voice "TAWS Not
Available" occurs. When sufficient GPS signal is returns and the aircraft is within the database coverage area,
the voice alert "TAWS Available" is generated.
