Collision Avoidance
TRAFFIC

The Odyssey and Voyager can monitor traffic from several sources (via the ARINC 429 interface), and will display traffic on the moving map page. Relative altitude is shown as well as the intruder’s ground track in certain cases.

The following systems are supported:

Zaon XRX
The Zaon PCAS (Portable Collision Avoidance System) is a popular portable traffic information system that can be used anywhere in the world and will track 3 intruders at a time using the other aircraft’s transponder replies.

Mode-S Transponder - TIS (Traffic Information Service)
The TIS system operates only in certain areas in the United States and requires a Mode-S Transponder such as the Garmin GTX330. More info here on TIS-issues, and coverage map is here.

TCAS
TCAS is an active transponder-interrogation system.

FLARM
