Aviation, or air transport, refers to the activities surrounding mechanical flight and the aircraft industry. Aircraft includes fixed-wing and rotary-wing types, morphable wings, wing-less lifting bodies, as well as lighter-than-air craft such as balloons and airships.
Aviation began in the 18th century with the development of the hot air balloon, an apparatus capable of atmospheric displacement through buoyancy. Some of the most significant advancements in aviation technology came with the controlled gliding flying of Otto Lilienthal in 1896; then a large step in significance came with the construction of the first powered airplane by the Wright brothers in the early 1900s. Since that time, aviation has been technologically revolutionized by the introduction of the jet which permitted a major form of transport throughout the world.
General aviation in the United Kingdom
has been defined as a civil aircraft
operation other than a commercial air transport
flight operating to a schedule. Although the International Civil Aviation Organization
excludes any form of remunerated aviation from its definition, some commercial operations are often included within the scope of general aviation in the UK
. The sector operates business jets
and jet-engined fixed-wing aircraft
of all descriptions, and lighter than air
craft. Public transport operations include business (or corporate) aviation and air taxi
services, and account for nearly half of the economic contribution made by the sector. There are 28,000 Private Pilot Licence
holders, and 10,000 certified glider pilots
. Although GA operates from more than 1,800 aerodromes
and landing sites, ranging in size from large regional airports
to farm strips, over 80 per cent of GA activity is conducted at 134 of the larger aerodromes. GA is regulated by the Civil Aviation Authority
, although regulatory powers are being increasingly transferred to the European Aviation Safety Agency
. The main focus is on standards of airworthiness
and pilot licensing
, and the objective is to promote high standards of safety.

The Airbus A380 is a double-deck, four-engined airliner manufactured by Airbus S.A.S. It first flew on 27 April 2005 from Toulouse-Blagnac Airport. Commercial flights began in late 2007 after months of testing, with the delivery of the first aircraft to launch customer Singapore Airlines. During much of its development phase, the aircraft was known as the Airbus A3XX, and the nickname Superjumbo has also become associated with the A380.
The A380 is double decked, with the upper deck extending along the entire length of the fuselage. This allows for a spacious cabin, with the A380 in standard three-class configuration to seat 555 people, up to maximum of 853 in full economy class configuration. Two models of the A380 will be available at launch. The A380-800, the passenger model, is the largest passenger airliner in the world superseding the Boeing 747. The other launch model, the A380-800F freighter, was canceled and will not join the ranks of the largest freight aircraft such as the Antonov An-225, An-124, and the C-5 Galaxy for the foreseeable future.
