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, rotorcraft, piston and jet-engined fixed-wing aircraft, gliders 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. (Full article...)
