Dual transponder system ADS-B upgrade in Part 25 aircraft

Duncan Aviation is proud to partner with ACSS to participate in the launch of the NXT-700 transponder and the development of the Approved Model List (AML) Supplemental Type Certificate (STC).

ACSS Offers NXT-700 ADS-B Compliant Transponder for Legacy Corporate Aircraft

ACSS, an L-3 and Thales Company, has developed an ADS-B transponder solution for legacy corporate aircraft, the NXT-700. This next-generation Mode S transponder will satisfy the DO-260B mandate for Automatic Dependent Surveillance-Broadcast (ADS-B) on many legacy aircraft models and will reduce owner/operator costs, as well as downtime, because it is a “one-quarter ATR short” form-fit installation.
