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:
“I thought ten thousand swords must have leaped from their scabbards to avenge even a look that threatened her with insult. But the age of chivalry is gone. That of sophisters, economists and calculators has succeeded; and the glory of Europe is extinguished forever.”
—Edmund Burke (1729–1797)
“I believe that the fundamental proposition is that we must recognize that the hostilities in Europe, in Africa, and in Asia are all parts of a single world conflict. We must, consequently, recognize that our interests are menaced both in Europe and in the Far East.”
—Franklin D. Roosevelt (1882–1945)
“The Federated Republic of Europe—the United States of Europe—that is what must be. National autonomy no longer suffices. Economic evolution demands the abolition of national frontiers. If Europe is to remain split into national groups, then Imperialism will recommence its work. Only a Federated Republic of Europe can give peace to the world.”
—Leon Trotsky (1879–1940)
