Garmin Announces FAA Certification, Availability of GTX 330 ES and GTX 33 ES

GarminRecently, Garmin received an Approved Model List Supplemental Type Certification (AML STC) that allows our GTX 330 ES and GTX 33 ES transponders to be installed in hundreds of makes and models of fixed-wing aircraft.  This certification qualifies these products for ADS-B NextGen compliance (with accompanying WAAS position source), and are an ideal solution for aircraft that fly at any altitude in the U.S. or outside of the U.S. where it will be required to broadcast on the 1090 frequency band. Customers that already own a GTX 330/33 transponder can purchase an ES upgrade from a Garmin Authorized dealer today for $1,200. For aircraft owners that already have a GTX 330 ES, GTX 33 ES or a GTX 23 ES, a free update is now available through Garmin Authorized Dealers.

Earlier this year, the FAA granted an AML STC for the GDL 88, a simple, ADS-B rule-compliant solution for aircraft operating in the U.S. and below 18,000 feet. The innovative dual-link capability allows the GDL 88 to receive both the 978 MHz UAT and 1090 MHz frequency bands to provide the most comprehensive level of traffic situational awareness. Advanced traffic awareness features include TargetTrend™ relative motion technology, which helps the pilot visualize the trend of the traffic threats as it relates to their aircraft, and SURF technology, which detects other aircraft or ground vehicles on runways and taxiways that may pose a threat while taxiing or on approach.
