Europe
In Europe, airways are corridors 10 nautical miles (19 km) wide of controlled airspace with a defined lower base, usually FL070-FL100, extending to FL195. They link the major airports giving protection to IFR flights during the climb and descent phases, and often for non-jet aircraft, cruise phases of flight. Historically they were laid out between VORs; however, advances in navigational technology mean that nowadays this is not always the case. Like European roads, each airway has a designator containing one letter and one to three numbers. All airspace above FL195 is class C controlled airspace, the equivalent to airways being called Upper Air Routes and having designators prefixed with the letter "U". If an upper air route follows the same track as an airway its designator will be identical to the airway, prefixed with the letter "U".
In the UK, airways are all Class A below FL195 and therefore VFR flights are prohibited.

Famous quotes containing the word europe:
“The heritage of the American Revolution is forgotten, and the American government, for better and for worse, has entered into the heritage of Europe as though it were its patrimony—unaware, alas, of the fact that Europe’s declining power was preceded and accompanied by political bankruptcy, the bankruptcy of the nation-state and its concept of sovereignty.”
—Hannah Arendt (1906–1975)
“In Europe life is histrionic and dramatized, and ... in America, except when it is trying to be European, it is direct and sincere.”
—William Dean Howells (1837–1920)
“Well then! Wagner was a revolutionary—he fled the Germans.... As an artist one has no home in Europe outside Paris: the délicatesse in all five artistic senses that is presupposed by Wagner’s art, the fingers for nuances, the psychological morbidity are found only in Paris. Nowhere else is this passion in questions of form to be found, this seriousness in mise en scène—which is Parisian seriousness par excellence.”
—Friedrich Nietzsche (1844–1900)
