Garmin Adds Tcas II, Mode S Transponder for Large Aircraft

Garmin introduced two new avionics products targeting the Part 25 transport category market, the new GTS 8000 Tcas II unit and GTX 3000 Mode S transponder. Both new products received FAA TSO certification on August 7 and will be fitted on upcoming new jets featuring Garmin G5000 avionics suites, including the Cessna Citation Ten, Latitude and Longitude and Bombardier Learjet 70 and 75. At Garmin’s NBAA exhibit (Booth No. 2758), the company is showing the G1000, G3000 and G5000 integrated flight decks, G600 glass panels, the new GWX solid-state radar, active traffic systems, ADS-B solutions, portable GPS units and the Garmin Pilot iPad app.

The GTS 8000 and GTX 3000 also can interface with Garmin G1000 through G5000 system and thus will be available for retrofit programs, according to avionics product manager Bill Stone. “We’re working through our initial airworthiness certifications with Cessna and Bombardier,” he said, “[then] looking for the retrofit market.” The GTS 8000 can also replace older Tcas processors and drive existing IVSI displays, and it weighs less, costs less and is more reliable than “typical” TCAS systems, according to Stone.

“This is a very natural progression for us,” he said. “We’ve got traffic products that serve general aviation, and as we move further into business aviation, there is a need for Tcas II or as Europe calls it Acas II. By designing it now, we’re able to bring it to market lighter, cheaper and much more reliable. And it’s fully in compliance with regulatory requirements, coming out of the gate with the [latest] Change 7.1 software.”

The GTS 8000, according to Stone, “blends both active interrogation and passive reception of ADS-B targets.” When a traffic target is within TCAS range, “through a process of correlation, the best attributes of both [Tcas and ADS-B] are combined to give a much more stable and accurate target.” The GTS 8000 will also support ADS-B software applications that will be part of the NextGen air traffic control environment.

The GTX 3000 is a remote-mounted transponder and, Stone said, “was designed for the operational and environmental needs of transport-category aircraft that operate in a more severe environment, and with much higher transmit power output than our other transponders.” The GTX 3000 will also be featured on G5000-equipped airplanes and on retrofit applications.

Both the GTS 8000 and GTX 3000, while already certified, will need individual supplemental type certificates for each make and model of Part 25 aircraft in which they will be installed. “We’re looking at the aftermarket to identify those good opportunities,” Stone said.
