Airbus A320 is a twin-engine medium-range jet airliner with a low wing of mainly French-German production. Drive is provided by two CFM International CFM56 or IAE V2500 turbofan engines. The flight of the prototype took place in 1987, and serial production began in 1988 and continues to this day. By the beginning of 2016, more than 6,800 aircraft of this type had been produced! The Airbus A320 was created as a machine that had to be offered primarily to European and Asian carriers as a competitor to the Boeing 727. The manufacturer Airbus emphasized in the new machine first of all the use of state-of-the-art electronics, primarily the fly-by-wire system known from military aviation (for example , from F-16 planes), but for the first time in a passenger plane! New avionics with a glass cockpit and a central flight control system were also used. A complete novelty was only a crew of two people, which clearly and positively affected the operating costs of the aircraft. In addition, the A320 has - compared to the first production versions - a 50% longer range than its main competitor, the Boeing 727. Due to low reliability and the use of many avant-garde solutions, the A320 proved to be excellent. the commercial success of Airbus. By 2012, aircraft of this type transported 7 billion people and flew for 120 million hours!
