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.
Oxfordshire[a] is a landlocked county in the far west of the government statistical region of South East England. The ceremonial county borders Warwickshire to the north-west, Northamptonshire to the north-east, Buckinghamshire to the east, Berkshire to the south, Wiltshire to the south-west and Gloucestershire to the west.
The county has major education and tourist industries, and is noted for concentrations of performance motorsport, car manufacturing and technology companies. The University of Oxford is widely considered one of the leading universities in the world, and is linked to a concentration of local technology and science activities at locations such as the Harwell Science and Innovation Campus, while Oxford University Press is the largest firm among a concentration of print and publishing firms.
As well as the city of Oxford, other centres of population are Banbury, Bicester, Kidlington and Chipping Norton to the north of Oxford; Carterton and Witney to the west; Thame and Chinnor to the east; and Abingdon-on-Thames, Wantage, Didcot, Wallingford and Henley-on-Thames to the south. All its zones south of the Thames: the Vale of White Horse and parts of South Oxfordshire were within the historic county of Berkshire, including the highest point, the 261-metre (856 ft) White Horse Hill.
Oxfordshire's county flower is the snake's-head fritillary.
