Easy Installation

  • No airframe modifications or additional antennas are required.
  • Works with any Mode C or Mode S transponder.
  • Transponder data is provided via the existing aircraft wiring system using the Power Transcoder.
  • TailBeacon uses the existing mounting location, breaker, and wiring.
  • The installation requires 2 screws and reuses the existing power and ground to your current position light.

Goof-Proof Configuration

Mechanically installing an ADS-B solution is only half the battle. The skyBeacon mobile application can also be used to configure tailBeacon. The intuitive, easy to use app guides you through setting the necessary values including the ICAO address, emitter type, aircraft length, width and GPS offsets. Since tailBeacon is self-contained there are no serial ports settings or protocols to configure.

The skyBeacon mobile application is available for both Apple iOS and Android.

Easy to install. I give this 5 stars because it seems to do everything that it advertised to do. Getting this ADS-B out product certified is straight forward after you get things figured out. When I called MSP Center to see if they could see the ADS-B out signal they said that they could not see it. Yet when I asked for a performance report it came back and said there were no issues. I guess the FAAs ADS-B out system is not up and running as I would have thought it should be.

Easy install, although my Cessna 170B needed a new ground wire run. The setup through the app was easy

Q: Is this Uavionix Tailbeacon 11-17246 STC approved?

Yes, the tailBeacon has an STC for the Cessna 172. The high-wing installation satisfies the FAA requirements and enables subsequent tailBeacon installations to be performed on any “suitable aircraft” without STC as a minor alteration. A suitable aircraft supports the installation of the tailBeacon without airframe modification.

Q: Can you replace the tail light in the Uavionix Tailbeacon if it burns out?

Per the manufacturer, this is an LED light rated for 10,000 hours of flight, but if something were to happen, please go to manufacturer for replacement or repair.

Q: Does this unit/app allow the pilot to input an alternate callsign such as for Angel Flight or Compassion flights?

The CALL SIGN can be up to an 8 digit code that corresponds to the tail number of the aircraft.

Q: Does this unit have anonymous mode capability?

Yes, this unit has an option for anonymous mode.

Yes, the Uavionix Tailbeacon is designed to work with both Mode C and Mode S transponders.

Q: Will this Uavionix Tailbeacon work on a PA28 R200?
