TAWS Operation
TAWS Manual Test
Garmin TAWS provides a manual test capability which verifies the proper operation of the aural and
visual annunciations of the system prior to a flight.
To manually test the TAWS system:
1. Select the TAWS Page and press MENU.
2. Select the ‘Test Terrain?’ option (Figure 2-5).
3. Press
ENT to confirm the selection.
An aural message is played giving the test results:
• “TAWS System Test, OK” if the system passes the test.
• “TAWS System Failure” if the system fail the test.
NOTE: TAWS System Testing is disabled when ground speed exceeds 30 knots so as not to
impede TAWS alerting.
