1. Select the TRAFFIC MAP page on the MFD.
2. Verify that the STANDBY, OPERATE, TEST and ALT MODE soft keys are available on the bottom
of the MFD. Verify that an operating mode; STANDBY, OPERATE, or TEST (not TAS FAIL) is
displayed in the upper left corner of the traffic map. Verify that NO DATA is not displayed in yellow
in the center of the display over the aircraft symbol.
NOTE
If the ALT MODE softkey is not displayed, the G1000 has not been properly configured
for the traffic system. Reference Section 3.15, “Traffic System Option” to enable the
traffic system.

traffic map.
4. Press the STANDBY soft key and verify that STANDBY is displayed in the upper left corner of the

and a traffic test pattern is displayed. Upon completion of the test, verify that “TAS SYSTEM TEST
OK” is heard over the cockpit speaker.

This annunciated traffic system test message may be different from the traffic system
installed on subject aircraft.
6. Open the TRFC circuit breaker on the avionics circuit breaker panel. On the MFD, verify that NO
DATA is displayed in yellow after several seconds.
