The FAA has released Safety Alert for Operators (SAFO) 24004 reminding light aircraft owners installing a uAvionix tailBeacon or skyBeacon ADS-B transceivers not to try to pair the unit to a Mode S transponder. Correctly installing requires pairing with a Mode A/C transponder.

According to the FAA, “Aircraft equipped with uAvionix tailBeacon or skyBeacon ADS-B 978 MHz Universal Access Transmitters (UAT) that are improperly paired with Mode S transponders have been found to emit erroneous and unreliable ADS-B performance parameters.”
