7.3 TRAFFIC SYSTEMS

TRAFFIC SOURCE
The G3X is compatible with three different traffic sources; TIS-A traffic via a Garmin
Mode S Transponder (GTX 33, GTX 330 or GTX 23), TAS via a GTS 800, or ADS-B/
TIS-B traffic via a GDL 39. When the G3X system is configured with both a Mode
S transponder capable of receiving TIS-A traffic and a GDL 39 capable of receiving
ADS-B/TIS-B traffic the G3X will automatically switch between traffic sources. The
following conditions describe the traffic display logic.
• If the GTX is not receiving TIS-A traffic data, GDL 39 ADS-B traffic will be displayed.
• If the GDL 39 is receiving both air-to-air ADS-B traffic data and ground uplink
TIS-B traffic, then the GDL 39 ADS-B traffic will be displayed.
• If the GTX is receiving TIS-A traffic, and the GDL 39 is not receiving ground uplink
TIS-B traffic, then GTX TIS-A traffic will be displayed.
If more than one traffic source is configured, the current traffic source is annunciated
in the upper left hand corner of the Traffic Page (TRF).
