DSNA – Direction des Services de la navigation aérienne

Safety remains a fundamental priority but the main priority for the future is to shape a Greener Aviation as a prerequisite for the effective restart of air transport in a sustainable manner. The implementation of 4-FLIGHT, the new-generation ATM system for en-route, in Reims and Marseille ACCs in 2022 proves the commitment of DSNA to pursue its technological modernisation, essential to deliver high-quality service.
