Regional airlineA regional airline is a general classification of airline which typically operates scheduled passenger air service, using regional aircraft, between communities lacking sufficient demand or infrastructure to attract mainline flights. In North America, most regional airlines are classified as "fee-for-departure" carriers, operating their revenue flights as codeshare services contracted by one or more major airline partners. A number of regional airlines, particularly during the 1960s and 1970s, were classified as commuter airlines in the Official Airline Guide (OAG).
Uncontrolled decompressionAn uncontrolled decompression is an undesired drop in the pressure of a sealed system, such as a pressurised aircraft cabin or hyperbaric chamber, that typically results from human error, structural failure, or impact, causing the pressurised vessel to vent into its surroundings or fail to pressurize at all. Such decompression may be classed as explosive, rapid, or slow: Explosive decompression (ED) is violent and too fast for air to escape safely from the lungs and other air-filled cavities in the body such as the sinuses and eustachian tubes, typically resulting in severe to fatal barotrauma.
Jet airlinerA jet airliner or jetliner is an airliner powered by jet engines (passenger jet aircraft). Airliners usually have two or four jet engines; three-engined designs were popular in the 1970s but are less common today. Airliners are commonly classified as either the large wide-body aircraft, medium narrow-body aircraft and smaller regional jet. Most airliners today are powered by jet engines, because they are capable of safely operating at high speeds and generate sufficient thrust to power large-capacity aircraft.
AirframeThe mechanical structure of an aircraft is known as the airframe. This structure is typically considered to include the fuselage, undercarriage, empennage and wings, and excludes the propulsion system. Airframe design is a field of aerospace engineering that combines aerodynamics, materials technology and manufacturing methods with a focus on weight, strength and aerodynamic drag, as well as reliability and cost. Modern airframe history began in the United States when a 1903 wood biplane made by Orville and Wilbur Wright showed the potential of fixed-wing designs.

La a commencé à régulariser l'aviation commerciale en établissant des normes, une facilitation et une promotion aux États-Unis.
Concorde (avion)vignette|Premier vol du prototype français du Concorde à Toulouse le , piloté par André Turcat. Le Concorde est un avion supersonique. Il s'agit d'un avion de ligne conçu conjointement par Sud-Aviation (devenue par la suite Aérospatiale puis Airbus) et British Aircraft Corporation (devenue ensuite British Aerospace). Il fut en service de 1976 à 2003 chez Air France et British Airways. Sa vitesse de croisière est de , soit environ , à une altitude variant de .
Aviation civilethumb|260px|Routes aériennes en 2009. L'aviation civile désigne tout ce qui est relatif à l'aviation non militaire. Cela englobe ainsi le transport civil de passagers et de marchandises, et en France les questions de . Le trafic augmente régulièrement (5,5 milliards de passagers en 2013) avec Atlanta comme premier aéroport (l'aéroport de Paris-Charles-de-Gaulle étant au mondial).
Boeing 777Le Boeing 777 ou B777, parfois surnommé triple sept dans le milieu aérien, est un avion de ligne gros porteur, long courrier et biréacteur construit par la société Boeing depuis 1993. Entré en service en 1995, il est le plus grand biréacteur au monde, avec une capacité de et une distance franchissable variant de selon les modèles. Il est reconnaissable par le grand diamètre de ses turboréacteurs GE90, ses six roues sur chaque train d'atterrissage principal et son fuselage de section circulaire se terminant en forme de lame.
