NXT-700 Mode S Transponder Satisfies The DO-260B Mandate For ADS-B

December 2016

The ACSS NXT-700 AML STC (Approved Model List Supplemental Type Certificate) of the NXT-700 Mode S transponder is complete and ready to meet the ADS-B mandate for many legacy aircraft operators. Developed through the collaborative efforts of Duncan Aviation and ACSS, the NXT-700 Mode S transponder satisfies the DO-260B mandate for ADS-B (Automatic Dependent Surveillance-Broadcast).

This 2MCU package includes solutions for WAAS and non-WAAS aircraft and can be installed through our full-service locations in Battle Creek, Michigan; Lincoln, Nebraska; and Provo, Utah; as well as most of the 23 other satellite avionics teams located throughout the United States.

We have the capability to perform NXT-700 installations on more than 50 different aircraft, including the following:

• Beechcraft Hawker 125-700A, 800, 800A, 800B, 800XP
• Beechcraft Hawker 400 SP/Beechjet, Early 400 Series
• Bombardier CL-600, 601 and 604
• Dassault Aviation Falcon 10, 20, 50, 200, 900, 900EX
• Gulfstream II, IIB, III, and IV
• Gulfstream 1125 Westwind/Astra
• IAI Westwind 1124, 1124A
• Learjet 25 Series, 31, 35, 35A, 36, 36A, 55
• Textron Aviation 550, 560, S550, and 650

The ACSS NXT-700 transponder will help legacy aircraft operators by providing avionics equipment that meets the ADS-B mandates. They will also save owner/operators costs and downtime because it is form-fit compatible with current retrofit Traffic Collision Avoidance System II (TCAS II) 7.1 systems 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.
