Launch of ADS-C pre-operational demonstration


Aircraft operated by EasyJet have started exchanging Automatic Dependant Surveillance – Contract (ADS-C) data with air traffic controllers at Eurocontrol’s Maastricht Upper Area Control Centre (MUAC).

Air France, British Airways, Iberia, Novair, Thomas Cook Airlines and Wizz Air will soon join the demonstration. Using ADS-C technology, aircraft log on to the MUAC system and automatically downlink flight management system information, which can be displayed on the controllers’ screens.
In particular, the flight management system downlinks the Extended Projected Profile (EPP), which consists of up to 128 waypoints in four dimensions, and therefore, provides valuable data to the controllers about the aircraft’s intent. Should it differ from the flight plan available to the air traffic controllers, they will receive a warning. Further information such as the top of descent is made available to the controllers too, so that continuous descent operations can be initiated more optimally. ADS-C has the potential to increase safety and ensure more efficient air traffic management service provision. The project has received funding from the SESAR Joint Undertaking under the European Union’s Horizon 2020 research and innovation programme.
