Aircraft avionics management system UniLink®

CDU

Increasingly congested skies demand a data link system with optimum management of two-way air-to-ground communications. The Universal Avionics UniLink UL-800 and UL-801 Communications Management Unit (CMU) provides superior operations and control of digital communications between the pilot and Air Traffic Controller (ATC) in the exceedingly complex Communication, Navigation, Surveillance (CNS) Air Traffic Management (ATM) environment. Developed in full compliance with DO-178B Level C guidelines, the UniLink UL-800/801 CMU also meets FANS 1/A+ standards. Combined with the Universal Avionics Satellite-Based Augmentation System (SBAS)–Flight Management System (FMS), the UniLink UL-800/801 CMU provides an opportunity to take full advantage of the safety and efficiency benefits that advanced data link capabilities offer. A Platform for the Future CNS / ATM Environment Fully compliant with the FANS 1/A+ mandate affecting operators in the North Atlantic Track System (NATS) and some Pacific Ocean routes, the UniLink UL-800/801 includes Controller-Pilot Data Link Communications (CPDLC) and Automatic Dependent Surveillance-Contract (ADS-C) functionality. With these FANS capabilities, operators gain preferred routing and options for altitudes with more favorable winds when in the NATS. Preferred routing provides a lower fuel burn and shorter station-to-station times, helping operators gain efficiencies that save fuel, time and money.
