TSO Granted for Tail-mounted ADS-B Transponder

The uAvionix tailBeaconX 1090 MHz ADS-B Out transponder has received FAA technical standard order (TSO) authorization. Approved model list STCs for installations are expected in the first quarter, covering a large number of aircraft models, the company said.

The tailBeaconX offers a unique advantage compared with typical light aircraft ADS-B Out transponders because its dipole antenna works with ground- and space-based ADS-B stations, including Aireon’s network built into Iridium’s new Next satellite constellation. Unless it is a diversity antenna installation (top and bottom fuselage-mounted), light aircraft ADS-B antennas are usually mounted on the fuselage belly for best reception with ground-based ADS-B stations. The tailBeaconX is also much simpler to install as it replaces tail-mounted position lights.

Included in the tailBeaconX are ADS-B Out, SBAS GPS receiver, and rear LED position light, and it meets TSOs that apply to each of those technologies. 

“Combining an LED rear position light replacement, a 1090 MHz Mode S [extended squitter] ADS-B Out transponder, SBAS GPS position source, and a dipole antenna into a single package was a major feat for our team, resulting in major cost reduction to our customers,” said uAvionix COO Ryan Braun. “Weighing only 140 grams, taking no critical panel space, while incorporating its own antennas, the path to ADS-B compliance is significantly simplified for a large group of aircraft.”

The preorder price is $2,499. The uAvionix AV-30-C multi-mode instrument can control the tailBeaconX and replaces attitude indicators and directional gyros but also displays angle-of-attack, air data, g meter, bus voltage, and GPS navigation.
