In January 2017 Duncan Aviation announced the upgrade and installation of ADS-B Out avionics equipment on a Challenger 850 SE.

The Duncan Aviation Satellite Avionics Shop in Las Vegas, Nevada, upgraded the displays, GPS sensors, and software in the cockpit before upgrading the Rockwell Collins TDR-94D transponder, bringing the aircraft into compliance with the FAA’s ADS-B Out mandate, which has a mandate coming due in 2020.

Using the Supplemental Type Certificate (STC) approved for use in the United States by the FAA and developed by Avmax (STC ST03651NY), headquartered in Calgary, Alberta, and the STC for Wide Area Augmentation System/Localizer Performance with Vertical Guidance (WAAS/LPV) developed by Rockwell Collins (STC ST01514WI-D), the Las Vegas shop readied the Challenger for WAAS/LPV and then performed the upgrades necessary for ADS-B Out.
