FreeFlight Systems expects STC approval later this summer for ADS-B Out and In for twin-turboprops. The new Avail Performance Package will be an approved model list STC covering King Airs and other popular twin-engine turboprops, the company announced at the Aircraft Electronics Association conference.

The Avail STC includes dual FDL­1090­TX mode-S/extended-squitter transponders, a Rangr RX/G ADS-B In receiver with internal WAAS GPS, built-in Wi-Fi, and a single control head. The FDL­1090­TX transponders are remote-mountable and can be installed anywhere inside the pressure vessel, according to FreeFlight. The control head fits in a standard 2.25-inch instrument mounting and features a sunlight-readable, backlit-LED display. ADS-B In traffic and weather can be displayed on panel-mounted MFDs or mobile devices.

“With just over two years remaining to meet the ADS­-B rule, there is a lack of cost­-effective, high-­quality options for twin turboprop aircraft," said Pete Ring, FreeFlight Systems vice president of sales and marketing. "This is an ideal solution for many of our clients [who prefer] a non­disruptive, remote­-mounted option.”

FreeFlight also announced that it has partnered with Avidyne to offer an ADS-B solution for Avidyne’s IFD series GPS/com navigators. The solution includes Avidyne’s IFD and AXP340 or AXP322 ADS-B-Out-capable mode-S transponder plus FreeFlight’s Rangr RX ADS-B In receiver. Avidyne can provide the entire package at a bundled rate.
