"Open skies" in commercial aviation solicits reliability and efficiency: air navigation in Europe

The European Union has a legal policy and economic profile, as well as a network route grid that presents a unique multinational analogous of the U.S. federal airspace system. The revised EUROCONTROL convention signed in 1997 by the member states was a landmark in European air traffic management development.
