General aviation (GA) refers to all civil aviation activities that are not part of scheduled airline services, encompassing private flying, flight training, aerial work such as surveying or firefighting, and non-scheduled charters. According to the International Civil Aviation Organization (ICAO), general aviation includes both personal and commercial aerial operations, making it one of the most diverse segments of the aviation sector. Its roots trace back to the 1920s, when private and club flying began to flourish, particularly in the United States and the United Kingdom.
