General aviation aircraft are a category of aircraft that are not used for commercial airline services or military purposes. They include a wide range of planes, from small single-engine propeller aircraft to larger business jets. These aircraft are primarily used for personal travel, flight training, aerial photography, and other non-commercial activities. General aviation plays a crucial role in the aviation industry, providing access to remote areas and supporting various sectors like agriculture and emergency services. Pilots of general aviation aircraft often require specific licenses and training, such as a Private Pilot License or Instrument Rating, to operate these planes safely.
