TRAFFIC PRIORITIZATION
The G3X Touch supports multiple traffic receivers and automatically prioritizes these
devices.
The following are the traffic receivers in order of priority:
- GTS 800 Active Traffic System
- GDL39/39R ADS-B traffic system receiving both air-to-air and TIS-B
- GTX23ES/GTX330ES TIS-A traffic system receiving TIS-A
- GDL39/39R ADS-B traffic system receiving only air-to-air
If the GTS 800 is turned off, the system will automatically use the next available
receiver according to priority.
