Following the announcement in May that ACSS has developed the NXT-700 ADS-B OUT transponder for legacy business aircraft, Duncan Aviation has partnered with ACSS to launch the new transponder and obtain an approved model list (AML) STC for installation in a variety of aircraft. Duncan Aviation expects to receive the AML STC from the FAA in the fourth quarter, followed by Transport Canada and EASA approval.

“The NXT-700 will save owner-operators costs and downtime because it is form-fit compatible with current retrofit TCAS II 7.1 systems,” according to Duncan Aviation, “and may be able to use the existing mounting rack and connectors for a quick installation. Since there are no additional control heads needed, the cockpit configurations will remain the same as well.” 

Aircraft that will be able to upgrade to the NXT-700 include the Hawker 125-400, 600 and 700, and Beechjet/Hawker 400XP; Gulfstream GIIB, III and V; Westwind 1124; Cessna CitationJet, Citation Ultra, V, VII and 550; Bombardier Learjet 35/35A and 36/36A; Dassault Falcon 10, 20, 50, 200, 900 and 900B; and Bombardier Challenger 601-3A and -3R.
