ACSS, an L-3 & Thales Company, announced today that Boeing has certified its NXT-800 Mode S transponder for Boeing 767 airplanes. The NXT-800 offers the most advanced level of Automatic Dependent Surveillance-Broadcast (ADS-B) Out transmission, which will be required to meet the approaching global mandates for ADS-B Out capability.

Optimized for flight in the NextGen air traffic environment, the NXT-800 transponder transmits own-ship flight parameters to other aircraft and air traffic control (ATC). The transmission of DO-260B-level ADS-B Out information provides more precise flight data, including position, speed and intent of the aircraft. The 4-MCU NXT-800 and the smaller NXT-600 received Technical Standard Order (TSO) authorization in 2014.

ADS-B Out mandates require all affected aircraft categories operating in the U.S. to be equipped with compliant Mode S transponders by no later than January 2020. New aircraft flying in Europe must be equipped by June 2016 and all in-service aircraft categories that are impacted need to be upgraded by June 2020.
