Civil Aviation Sector:
Civil aviation is one of two significant categories of aerospace, representing all non-military aviation, private and commercial. Civil aviation incorporates scheduled air transport, comprising all passenger and cargo flights operating on regularly scheduled routes, and general aviation (GA), including all other civil flights, private or commercial. Although scheduled air transport is more significant in terms of passenger numbers, general aviation is larger regarding the number of flights and flight hours.
Every scheduled air transport is commercial, but general aviation can be either commercial or private. Commercial aviation involves most, or all flying done for hire, particularly scheduled airline service. Private aviation includes pilots flying for their objectives like recreation, business meetings, etc., with or without receiving any remuneration.
The global civil aerospace products manufacturing sector handles every aspect of civil aviation. For instance, companies in the civil sector manufacture total civil aircraft, propulsion units, aerospace engines, and auxiliary equipment or parts. The main products and services in the civil aerospace sector incorporate general, regional, and large aircraft, as well as aircraft engines and other parts.
Military Aviation Sector:
Military aviation uses aircraft and other flying machines to conduct or enable warfare, including national airlift (cargo) capacity to provide logistical supply to forces stationed in a unit or base or along a front. Airpower incorporates the national means of conducting such warfare, including the intersection of transport and warcraft. The wide range of military aircraft includes bombers, fighters, fighter bombers, transports, trainers, and reconnaissance aircraft.
The military sector comprises companies that manufacture complete fighter, bomber, or military transport aircraft or missiles. They manufacture aircraft, including ground-attack aircraft, Attack helicopters, Bombers, Fighters, Multirole combat aircraft, Reconnaissance aircraft, and Military transport aircraft. Experimental aircraft are produced to test advanced aerodynamic, structural, avionic, or propulsion concepts.
Other companies in this area manufacture aerospace engines, propulsion units, missile guidance systems, or auxiliary parts. Prototypes of aerospace products are also advanced in this sector, as are modifications to aircraft systems and complete aircraft overhauls.
