Question: The International Civil Aviation Organization ( ICAO ) defines general aviation ( GA ) as an aircraft operation other than a commercial air transport operation or an aerial work operation . It defines commercial air transport ( CAT ) as an aircraft operation involving the transport of passengers , cargo or mail for remuneration or hire , and aerial work as an aircraft operation in which an aircraft is used for specialized services such as agriculture , construction , photography , surveying , observation and patrol , search and rescue , aerial advertisement , etc .Organisations in the United Kingdom ( UK ) describe GA in less restrictive terms that include elements of commercial aviation . The British Business and General Aviation Association interprets it to be all aeroplane and helicopter flying except that performed by the major airlines and the Armed Services . The General Aviation Awareness Council applies the description all Civil Aviation operations other than scheduled air services and non @-@ scheduled air transport operations for remuneration or hire . For the purposes of a strategic review of GA in the UK , the Civil Aviation Authority ( CAA ) defined the scope of GA as a civil aircraft operation other than a commercial air transport flight operating to a schedule , and considered it necessary to depart from the ICAO definition and include aerial work and minor CAT operations .fill in the blank :The __________________ Civil Aviation Organization ( ICAO ) defines general aviation ( GA ) as an aircraft operation other than a commercial air transport operation or an aerial work operation .
