As TSO certification day approaches ever closer for uAvionix' SkyBeacon, an event reportedly just a few weeks away, company reps told Flying they had just enough time to add one more important feature to the ADS-B Out wingtip solution, an altitude encoder. That brings the number of useful internal tools inside the SkyBeacon to five. The SkyBeacon is designed to be a low-cost method of compliance with the FAA's 2020 ADS-B Out mandate. Other SkyBeacon features include the ADS-B Out unit, a WAAS GPS receiver, a position light and an anti-collision light, all designed for easy installation on the left wingtip of many aircraft. A complimentary product called SkySensor is on the list for certification that will add ADS-B In capabilities when the unit is installed in place of the right wingtip light.
