Avionics manufacturer uAvionix on Jan. 26 announced FAA technical standard order (TSO) authorization of its tailBeaconX 1090 MHz automatic dependent surveillance-broadcast Out (ADS-B Out) transponder, which replaces a rear navigation light on general aviation aircraft.
The tailBeacon X combines a transponder, 1090 MHz ADS-B Out signaling, satellite-based augmentation system (SBAS) GPS position source, and rear LED position light. It integrates with the uAvionix AV-30-C primary flight display for transponder control and GPS input.
The transponder antenna is compatible with both terrestrial ADS-B ground stations and the Aireon space-based ADS-B network, which uses receivers on Iridium Next satellites.
A traditional transponder and ADS-B system share a single, bottom-mounted antenna, which requires line of sight access to ground-based receivers. The dipole antenna pattern of the tailBeacon X resembles what a top- and bottom-mounted monopole antenna would yield, and is unobstructed by the aircraft fuselage.
Supplemental type certification programs “are in work” for a large Approved Model List of aircraft, with completion expected in the first quarter, said uAvionix, which has a manufacturing base in Bigfork, Montana.
The company is offering the tailBeaconX for preorder for $2,499, with a $300 discount to bundle it with the AV-30-C display.
“Combining a LED rear position light replacement, a 1090MHz 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 Ryan Braun, uAvionix COO. “The path to ADS-B compliance is significantly simplified for a large group of aircraft.”
The system authorization includes TSO-C112e Mode S transponder; TSO-C166b ADS-B Out Extended Squitter; TSO-C145e SBAS GPS position source; and TSO-C30c rear LED position light.
