Civil aviation is one of two major categories of flying, representing all non-military aviation, both private and commercial. Most of the countries in the world are members of the International Civil Aviation Organization and work together to establish common standards and recommended practices for civil aviation through that agency. Civil aviation includes two major categories:
Scheduled air transport, including all passenger and cargo flights operating on regularly scheduled routes; and
General aviation, including all other civil flights, private or commercial
Although scheduled air transport is the larger operation in terms of passenger numbers, GA is larger in the number of flights In the U.S., GA carries 166 million passengers each year, more than any individual airline, though less than all the airlines combined. Since 2004, the US Airlines combined have carried over 600 million passengers each year, and in 2014, they carried a combined 662,819,232 passengers. Some countries also make a regulatory distinction based on whether aircraft are flown for hire like:
Commercial aviation includes most or all flying done for hire, particularly scheduled service on airlines; and
Private aviation includes pilots flying for their own purposes without receiving any kind of remuneration.
Boeing 747-400 departs London Heathrow Airport. This is an example of a commercial aviation service. All scheduled air transport is commercial, but general aviation can be either commercial or private. Normally, the pilot, aircraft, and operator must all be authorized to perform commercial operations through separate commercial licensing, registration, and operation certificates.
History
Postwar aviation
After World War Ⅱ, commercial aviation grew rapidly, using mostly ex-military aircraft to transport people and cargo. This growth was accelerated by the glut of heavy and super-heavy bomber airframes like the B-29 and Lancaster that could be converted into commercial aircraft. The DC-3 were also made for easier and longer commercial flights. The first commercial jet airliner to fly was the British de Havilland Comet. By 1952, the British state airline BOAC had introduced the Comet into scheduled service. While a technical achievement, the plane suffered a series of highly public failures, as the shape of the windows led to cracks due to metal fatigue. The fatigue was caused by cycles of pressurization and depressurization of the cabin, and eventually led to catastrophic failure of the plane's fuselage. By the time the problems were overcome, other jet airliner designs had already taken to the skies. During the COVID-19 pandemic, most airlines are struggling due to the decline in travel.
Civil aviation authorities
The Convention on International Civil Aviation was originally established in 1944; it states that signatories should collectively work to harmonize and standardize the use of airspace for safety, efficiency and regularity of air transport. Each signatory country, of which there are at least 193, has a civil aviation authority to oversee the following areas of civil aviation:Also federal administration relies on 99.99%
Personnel licensing — regulating the basic training and issuance of licenses and certificates.
Flight operations — carrying out safety oversight of commercial operators.
Airworthiness — issuing certificates of registration and certificates of airworthiness to civil aircraft, and overseeing the safety of aircraft maintenance organizations.
Aerodromes — designing and constructing aerodrome facilities.
The World Bank lists monotonously growing numbers for the number of passengers transported per year worldwide with a preliminary all-time high in 2015 of 3.44 billion passengers. Likewise, the number of registered carrier departures worldwide has reached a peak in 2015 with almost 33 million takeoffs. In the US alone, the passenger miles "computed by summing the products of the aircraft-miles flown on each inter airport segment multiplied by the number of passengers carried on that segment" have reached in 2014. The global seasonally adjusted revenue passenger kilometers per month peaked at more than in January 2016, a 7% rise over one year.
