The Garmin GTX-330 transponder will revolutionize traffic avoidance for small aircraft.
The Garmin GTX330 Mode S transponder will give the GNS-430/530 owner ATC traffic on the GPS screen. Until this time, this type of information has only been available via a BFG Skywatch, or RYAN TCAD device costing around $16000.00 to install. The FAA is providing traffic uplink to Mode S users at no cost to the user as an incentive to switch to a mode S transponder. The FAA program is called T.I.S for Traffic Information System. When a GTX-330 user shows up on an ATC approach radar system, the ATC facility computer using T.I.S. software will calculate traffic threats within 6 miles and +/- 3500 feet of your aircraft. The threat information is then sent to your aircraft via the Mode S data-link in the GTX330 xpdr. The GTX-330 will then send the traffic information the Garmin GNS430/530 via a 429 data bus. The traffic will be displayed on the 430/530 screen with altitude tags (how far the threat aircraft is from your aircraft in 100's of feet) and a trend vector (what direction the threat aircraft is moving). There will be a verbal call out in you audio system warning you of the traffic. This traffic information is only available within 60nm of FAA approach radar facilities with T.I.S. equipment. Center radar is not available at this time. The GTX 330 also has an altitude alerter option that allows the pilot to set a target altitude, then the GTX330 will make verbal altitude call outs for you.
