Duncan Aviation Readies Challenger 850 SE for ADS-B
The installation combined a Canadian-developed STC and a Rockwell Collins STC to prepare the aircraft for WAAS/LPV and bring it into ADS-B OUT compliance.

Duncan Aviation recently completed an upgrade and installation of ADS-B OUT-compliant equipment on the Bombardier Challenger 850 SE. Duncan’s satellite avionics shop in Las Vegas installed a Rockwell Collins TDR-94D transponder on a Challenger 850 SE, along with displays, GPS sensors and software, bringing the aircraft into compliance with the U.S. ADS-B OUT mandate.
