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 think the Americans are the only people who have good beds. I consider the American bedroom unparalleled for freshness, comfort, and cleanliness. It is worth going all over Europe in order to come home to one’s own bed.”
—M. E. W. Sherwood (1826–1903)
“You can always tell a Midwestern couple in Europe because they will be standing in the middle of a busy intersection looking at a wind-blown map and arguing over which way is west. European cities, with their wandering streets and undisciplined alleys, drive Midwesterners practically insane.”
—Bill Bryson (b. 1951)
“The Cold War began with the division of Europe. It can only end when Europe is whole.”
—George Bush (b. 1924)
