 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 or military aviation . Although the International Civil Aviation Organization ( ICAO ) excludes any form of remunerated aviation from its definition , some commercial operations are often included within the scope of general aviation ( GA ) in the UK . The sector operates business jets , <unk> , 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 . Other commercial GA activities are aerial work , such as surveying and air ambulances , and flight training , which plays an important role in the supply of pilots to the commercial air transport ( CAT ) industry . Private flying is conducted for personal transport and recreation . It includes a strong vintage aircraft movement , and encompasses a range of air sports , such as racing , aerobatics , and <unk> , at which British teams and individuals have succeeded in international competition .
