System Status; Taws Abnormal Operations - Garmin G2000 Pilot's Manual

ALTITUDE VOICE CALLOUT (VCO)
TAWS provides an aural advisory alert as the aircraft descends through 500 feet above the terrain (if greater
than 5 nm from the nearest airport) or 500 feet above the nearest runway threshold elevation (if less than 5
nm from the nearest airport). Upon descent to this altitude, TAWS issues a "Five-hundred" voice alert.
There are no display annunciations or pop-up alerts that accompany the aural message(s). The VCO alert
cannot be inhibited.

SySteM StatuS

During power-up, TAWS conducts an automatic system test. The test can also be manually initiated. The
system issues a voice alerts when the test is finished. TAWS System Testing is disabled when ground speed
exceeds 30 knots. TAWS terrain alerts will not be issued while a test is in progress.

taWS abnorMal oPerationS

TAWS continually monitors several system-critical items such as database validity and GPS status.
If no neither the PFD nor MFD contains Terrain and Obstacle databases (or the databases are invalid), 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 Pane. The voice alert "TAWS Not
Available" is also generated if airborne. . When the system receives sufficient GPS signal and the aircraft is
within the database coverage area, the system issues a "TAWS Available" voice message.
