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

Garmin has 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

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.
