TAWS/TERRAIN

Basic Operation

Power Up
During power-up of the G1000 unit, terrain/airport
terrain/obstacle database versions and area of coverage are
displayed along with a disclaimer. At the same time, the
TAWS/TERRAIN system self-test begins. An aural mes-
sage plays upon test completion:
• "TAWS System Test, OK", if the system passes the
test.
• "TAWS System Failure", if the system fails the
test.
A failure of the test is annunciated for both TAWS and
TERRAIN, if the self-test fails.

Database Updates

Terrain/airport terrain/obstacle databases are updated
periodically with the latest terrain/airport terrain/obstacle
data. Visit the Garmin website to check for newer versions
of terrain/airport terrain/obstacle databases. Updated ter-
rain data cards may be obtained from the Garmin website
or by calling Garmin at one of the numbers listed in the
front of this document.
