In 1995, Aérospatiale of France, a founding partner of EADS, embarked on a long-term project to develop the Air Traffic Services Unit (ATSU) computer for Airbus 320, 330, and 340 aircraft, part of the Future Air Navigation Systems (FANS) program. The Aérospatiale ATSU (Air Traffic Services Unit) integrates all services dedicated to data communication between the aircraft and the air traffic centers, all the needed resources to implement the future ATN Network, as well as the present ACARS functions (Aircraft Communication Addressing and Reporting System). This project marked the first time that a commercial RTOS would be used in a computer-controlled navigation system certified to DO-178B level C. |
Aérospatiale chose the LynxOS® real-time operating system (RTOS) to power these next-generation Airbus flight-control systems after evaluating dozens of RTOS suppliers during a year-long review process. Aérospatiale finally chose LynxOS for price, performance, reliability and portability. |
