Does the Garmin GTX 330 have ads-B?
Unlike the regular GTX-330 Transponder, the GTX-330ES offers ADS-B Out capability and will meet the 2020 mandate. The GTX-330ES transmits using the 1090 MHz Extended Squitter (1090ES) standard. MHz Extended Squitter (1090ES) Transmitters are permitted at any altitude and required above 18,000 feet. The GTX-327 is Garmin’s best Mode C Transponder. It lacks the GTX-330’s TIS traffic features, or the ADS-B capability of newer Transponders. However, it you are using other avionics for ADS-B (or are not subject to this mandate), the GTX-327 is an excellent unit, with many helpful convenience features.
