On September 30, 2011, David McMillan, Director General of EUROCONTROL, offered his assessment of the future of European air traffic management (ATM). With airspace and airport capacity constraints a reality on both sides of the Atlantic, Mr. McMillan outlined the progress of the European Union's Single European Sky Initiative, including a new performance driven regime that will set binding targets on capacity, cost-efficiency and environmental impact, beginning next January. Highlighting the strong working relationship with the FAA, Mr. McMillan urged even closer European-American cooperation in developing globally interoperable ATM solutions.
