The GTX 330 can only be sold over the counter to experimental aircraft owner's with a pre-wired harness.

Mode "S" has send/receive capabilities and GARMIN will be using this ability to send the same primary radar information ATC sees up to the aircraft to be displayed on the GARMIN 400/500 series units. Known as T.I.S., this TRAFFIC INFORMATION is received from the ATC system and therefore requires the aircraft to be within a radar environment.

The traffic will be displayed on the moving map using standard traffic symbols, white targets (less of a threat) and yellow targets shown as objects of immediate concern with their respective altitudes and trend info (ascent or descent). An added safety bonus is having these targets shown with "VECTOR LINES". These lines will extend from the traffic symbols showing the direction of travel, thereby eliminating the need for the pilot to "study" the screen in order to disseminate which aircraft is coming in his direction, etc.

The GTX 330 will also have voice capability enabling the pilot to "hear" the warnings regarding traffic of concern through their headset or over the cabin speaker.

Adding to the list of useful features, GARMIN has included an ALTITUDE ALERTER whereby the pilot merely sets the preferred altitude and the transponder will advise via voice and visual warnings if the aircraft ascends or descends through the programmed altitude buffer. The altitude buffer (100ft., 200ft. etc.) can be set for the pilots comfort level of choice.

In addition, the transponder will display "indicated altitude" (the altitude the encoder is reporting), count-up, count-down timers and flight time.
