Aix-Geneva-Interface: improved dynamic cross-border sectorisation between France and Switzerland increases safety and fluidity

- Langen, Germany

In October, FABEC members DSNA (France) and Skyguide (Switzerland), have successfully implemented a new interface between the control centres of Marseille and Geneva. Thanks to a new set up of the areas of responsibility and improved coordination, the number of potential conflicts between aircraft flying from and to Geneva and Lyon airports can be reduced and fluidity of traffic increased. 

For this, the limits of the Geneva terminal maneuvering area (TMA) which lies in the French airspace delegated to skyguide and the boundaries of the Geneva flight information service (FIS) area were modified, the management of FIS between the ACCs Marseille and Geneva reorganized and an innovative, shared dynamic zone of responsibility created which is now regularly activated. 

All preparatory work was conducted in close cooperation between DSNA and Skyguide: definition of concept, safety assessment, common real time simulations, training and transition to operation. The implemented design best suits all needs and is the result of continuous and result-oriented cooperation in a FABEC spirit. The same positive approach was also engaged by the supervisory authorities in both countries during the safety assessment. 

Maurice GEORGES, CEO DSNA says:

"I would like to thank all partners who contributed to this achievement. This exemplary cooperation was fed by mutual trust. The complementarity of our organisation was key to the successful outcome of this complex project which benefits all our customers." 

Alex BRISTOL, CEO Skyguide says:

"DSNA has been our strategic partner for years. All airspace users in the Geneva/Lyon area take direct advantage from this close alliance. This is the spirit we want to promote in the Single European Sky, and FABEC is our vehicle on this path."
