DSNA (Direction des Services de la Navigation Aérienne), the French Air Navigation Service Provider, aims to deliver the best quality of service to all users in one of the busiest airspaces in the world.
DSNA mission consists of controlling air traffic in a safe, fluid and environmentally-friendly manner, while keeping costs under control. Safety remains a fundamental priority but the main activity for the future is to shape a Greener Aviation as a prerequisite for the effective restart of air transport in a sustainable manner.
DSNA operates five en-route control centres (ACC) and nine mainland regional structures (SNA) for approach and aerodrome control services (75 control towers), along with three overseas regional structures. Due to its size (1 million km2) and position at the crossroads of the major European air traffic routes, France manages dense and complex traffic with strong seasonal variations and high daily peaks. In 2021, the breakdown of air traffic controlled in France was as follows: 47% were overflights, 35% were international flights to or from France and 18% were domestic flights. The daily traffic peak was recorded with 8,104 flights on Saturday 28 August 2021.
The workforce of DSNA amounts to 6,900 employees with a male-female distribution of 73% – 27%. Operational personnel counts for 66% of staff.
Services for even safer, more performant
and greener Aviation
The encouraging result of 2021 traffic following to an unprecedented crisis for aviation is a great motivation for DSNA staff to accompany a gradual and sustainable recovery of air transport that will be more digital, with very ambitious environmental requirements.
DSNA has been pushing for greener initiatives to promote an environmental culture and to accelerate this crucial transition. An environmental strategy has been developed for the entire flight phases (departure, climb, cruise, descent and arrival) to improve flight profiles and to optimise flight efficiency : extended Collaborative Decision-Making (CDM), advanced Flexible Use of Airspace (FUA) and Free Route, extended Arrival Management (AMAN). DSNA also particaptes in innovative projects such as Fello’fly (how to fly in formation long haul civil aircraft) and the European projects of the SESAR programme to improve the prediction of aircraft trajectory in air traffic management (ATM) or to find quick solutions to deliver environmental benefits both on the ground and in the air.
DSNA also is very involved to pursue and success its technological modernisation, essential to deliver high performant service. For example, the implementation of 4-FLIGHT, the new-generation ATM system for en-route, in Reims and Marseille ACCs scheduled in 2022 will be of significant benefit not only to France but also to the entire European network.
In terms of innovation, DSNA and skyguide, the Swiss ANSP, are testing a pioneering initiative of the virtualised air traffic control services (the Coflight Cloud Services - CCS project) that are at the core of the European vision. CCS is a future solution for the operational needs of air navigation operators in terms of rationalisation of the infrastructure, delegation of airspace and assistance.
DSNA deployed new advanced satellite-based arrival procedure (RNP AR) at Ajaccio airport (Corsica) in April 2022 to increase airport accessibility and to reduce noise and fuel burn.
