A6 alliance
The A6 alliance is formed of the six ANSP members of the SESAR JU – Aena (Spain), DFS (Germany), DSNA (France), ENAV (Italy), NATS (UK) and NORACON – a consortium including Austro Control (Austria), AVINOR (Norway), EANS (Estonia), Finavia (Finland), IAA (Ireland), LFV (Sweden) and Naviair (Denmark).



The SESAR (Single European Sky ATM Research) programme is a key element of the initiative launched by the European Commission to create a Single European Sky. It is its aim to eliminate the fragmentation of national air traffic management systems and procedures, to pool the know-how of the aviation sector, and to establish a uniform air traffic management network by the year 2020. Thus, for the first time in history, all aviation players, including the armed forces, are trying to meet jointly defined performance targets and to fulfil the requirements in terms of capacity and safety for the next 30 years.

Political objectives of SESAR:

Capacity – Tripling volume
The capacity on the ground and in the air will be tripled in order to reduce delays and handle the growth in air traffic also after the year 2020. However, for reasons of cost-effectiveness only the actually required capacity will be provided. The focus continues to be on safety and service quality.

Safety – Preventing ATM-related accidents
As a result of the expected air traffic growth, safety is to be improved by a factor of 10.

Environment – Reducing fuel consumption
The contribution towards environmental protection is a reduction of the relative fuel consumption of gate-to-gate traffic. ATM-related CO2 emissions should be reduced by 10%. Besides, noise emissions are to be reduced.

Cost-effectiveness – Reducing ATM costs per flight by 50%
The average gate-to-gate ATM costs in Europe of 800 EUR per flight (EUROCONTROL Performance Review Report 2005) are to be reduced by half to 400 EUR per flight by 2020. Further cost reductions will also be pursued after 2020.
