An original Single European Sky (SES1) package came into force in 2004. At the time the greatest problem in air traffic management was congestion in the air and subsequent delays hence it also became the main focus of SES1, together with safety. During the past years the ATM (Air Traffic Management) situation has changed somewhat and whilst safety and capacity are still major issues, the picture has become more varied with a greater emphasis on environment and more recently due to the fuel price crisis, on cost efficiency. Additionally, the regulatory approach has been changed due to requests from Member States and stakeholders for a less prescriptive approach ("better regulation"). That is why the new legislation would put more emphasis on the goals, than the means to reach the goals. This document gives a short outline of the main new initiative; it is not exhaustive and does not cover the relevant parts of SES1, which still remain in force.
