More than four years after debuting the TX family of nav/com units, the U.K.- based avionics manufacturer announced that its TX56, TX56A, TX57, and TX57A units are now all available with a free FAA STC that “contains practical resources designed to help Approved Trig Dealers execute an efficient installation, providing reassurance of compliance for qualified installers,” the company said in a press release.

TJ Spitzmiller, test and evaluation pilot for Trig's STC partner Peregrine, said in the press release, “We conducted a rigorous review of the TX56, covering all aspects of installation and operational performance. The TX56 is impressive, it occupies less space in the panel than other Nav/Coms. We found it easy to install and use in flight. The clarity of the display and user interface is superb, clearly showing both Com and Nav information. The unit has unique features, such as ‘Say Again’ on the radio, and the ability to monitor two Com and two VOR frequencies. The custom frequency database allows the pilot to load frequencies and identifiers to best suit their flight profile. It’s good to fly with a product that is well designed and simple to use, the TX56 is a great example of both!”

The TX56 comes with an approved model list that includes more than 650 general aviation fixed wing aircraft. The STC also includes configuration of both legacy and modern VOR and ILS autopilots.

According to the company, authorized Trig dealers can access the STC through the Trig Dealer Portal. Installers interested in accessing the STC should email Trig Avionics for support. The TX56A is $4,846 and can be purchased from an approved Trig Dealer.
