The European Commission is taking to task the vast majority of its 27 nation states for their lack of progress in forging the Single European Sky through a program to unify regional airspace.
Inefficiencies caused by Europe’s fragmented airspace generate extra costs of close to €5 billion each year, adding 42 kilometers (27 miles) to the distance of an average flight, and forcing aircraft to burn more fuel, generate more emissions, pay more in user charges and incur delays. The U.S. controls the same amount of airspace, with more traffic, at almost half the cost.
