Civil aviation is one of two major categories of flying, representing all non-military and non-state aviation, both private and commercial. Most of the countries in the world are members of the International Civil Aviation Organization (ICAO) and work together to establish common standards and recommended practices for civil aviation through that agency.
Civil aviation includes three major categories:
Commercial air transport, including scheduled and non-scheduled passenger and cargo flights
Aerial work, in which an aircraft is used for specialized services such as agriculture, photography, surveying, search and rescue, etc.
General aviation (GA), including all other civil flights, private or commercial
Although scheduled air transport is the larger operation in terms of passenger numbers, GA is larger in the number of flights (and flight hours, in the U.S.) In the U.S., GA carries 166 million passengers each year, more than any individual airline, though less than all the airlines combined. Since 2004, the US Airlines combined have carried over 600 million passengers each year, and in 2014, they carried a combined 662,819,232 passengers.
Some countries[which?] also make a regulatory distinction based on whether aircraft are flown for hire like:
Commercial aviation includes most or all flying done for hire, particularly scheduled service on airlines; and
Private aviation includes pilots flying for their own purposes (recreation, business meetings, etc.) without receiving any kind of remuneration.
A British Airways Boeing 747-400 departs London Heathrow Airport. This is an example of a commercial aviation service.
All scheduled air transport is commercial, but general aviation can be either commercial or private. Normally, the pilot, aircraft, and operator must all be authorized to perform commercial operations through separate commercial licensing, registration, and operation certificates.
Non-civil aviation is referred to as state aviation. This includes military aviation, state VIP transports, and police/customs aircraft.
The London Borough of Croydon (audio speaker iconpronunciation (help·info)) is a London borough in south London, part of Outer London. It covers an area of 87 km2 (33.6 sq mi). It is the southernmost borough of London. At its centre is the historic town of Croydon from which the borough takes its name; while other urban centres include Coulsdon, Purley, South Norwood, Norbury, New Addington and Thornton Heath. Croydon is mentioned in Domesday Book, and from a small market town has expanded into one of the most populous areas on the fringe of London. The borough is now one of London's leading business, financial and cultural centres, and its influence in entertainment and the arts contribute to its status as a major metropolitan centre. Its population is 386,710, making it the second largest London borough and fifteenth largest English district.
The borough was formed in 1965 from the merger of the County Borough of Croydon with Coulsdon and Purley Urban District, both of which had been within Surrey. The local authority, Croydon London Borough Council, is now part of London Councils, the local government association for Greater London. The economic strength of Croydon dates back mainly to Croydon Airport which was a major factor in the development of Croydon as a business centre. Once London's main airport for all international flights to and from the capital, it was closed on 30 September 1959 due to the lack of expansion space needed for an airport to serve the growing city. It is now a Grade II listed building and tourist attraction. Croydon Council and its predecessor Croydon Corporation unsuccessfully applied for city status in 1954, 2000, 2002 and 2012. The area is currently going through a large regeneration project called Croydon Vision 2020 which is predicted to attract more businesses and tourists to the area as well as backing Croydon's bid to become "London's Third City" (after the City of London and Westminster). Croydon is mostly urban, though there are large suburban and rural uplands towards the south of the borough. Since 2003, Croydon has been certified as a Fairtrade borough by the Fairtrade Foundation. It was the first London borough to have Fairtrade status which is awarded on certain criteria.
The area is one of the hearts of culture in London and the South East of England. Institutions such as the major arts and entertainment centre Fairfield Halls add to the vibrancy of the borough. However, its famous fringe theatre, the Warehouse Theatre, went into administration in 2012 when the council withdrew funding, and the building itself was demolished in 2013. The Croydon Clocktower was opened by Queen Elizabeth II in 1994 as an arts venue featuring a library, the independent David Lean Cinema (closed by the council in 2011 after sixteen years of operating, but now partially reopened on a part-time and volunteer basis) and museum. From 2000 to 2010, Croydon staged an annual summer festival celebrating the area's black and Indian cultural diversity, with audiences reaching over 50,000 people.
Premier League football club Crystal Palace F.C. play at Selhurst Park in Selhurst, a stadium they have been based in since 1924. Other landmarks in the borough include Addington Palace, an eighteenth-century mansion which became the official second residence of six Archbishops of Canterbury, Shirley Windmill, one of the few surviving large windmills in Greater London built in the 1850s, and the BRIT School, a creative arts institute run by the BRIT Trust which has produced artists such as Adele, Amy Winehouse and Leona Lewis.
