The Airbus A320 single-aisle medium-range airliner first entered service in 1988 and more than 5,000 aircraft of the A320 family are in service today, with more than 8,600 ordered.
The A320 family includes the A319 and A318 short-bodied versions and the A321 stretched version. The A319 entered service in 1996, the A321-100 in 1994 and the A321-200 in 1997. The A318 made its first flight in January 2002 and entered service in July 2003. The A320 was the first subsonic airliner to have a fly-by-wire flight control system.
Airbus Industrie is a consortium formed by EADS and BAE Systems. EADS, the European Aeronautic Defence and Space Company, was formed by a merger of Aerospatiale-Matra of France, Daimler-Chrysler Aerospace of Germany and CASA of Spain (former members of Airbus).
In October 2006, BAE Systems completed the sale of its shareholding to EADS, which is now the sole owner of Airbus.

In June 2007, Airbus set up a joint venture with a consortium of Chinese companies for the setting up of a final assembly line for A320 family aircraft in Tianjin. Aircraft assembly began in August 2008 and the first aircraft assembled in China was delivered in June 2009 to Sichuan Airlines. The 50th A320 jetliner assembled at the Tianjin was delivered to Shanghai-based Juneyao Airlines in June 2011. China Aviation Supplies Import and Export Group (CASGC) placed an order for 110 A320s in February 2008.
A total of 88 A320s were ordered jointly by China Aviation Supplies (CAS) and Industrial and Commercial Bank of China (ICBC) Leasing in June 2011. The orders include 46 aircraft for CAS and 42 for ICBC Leasing.

Thai Airways ordered five A320s in October 2011 to operate in domestic and regional routes.
In October 2011, TAM Airlines ordered 32 aircraft including 22 A320neos and ten A320s.
Qantas Airlines signed a $9.5bn contract with Airbus in October 2011 to procure 78 A320neos and 32 A320 jetliners.
In January 2012, AviancaTaca signed a contract for 33 eco-efficient A320neo and 18 A320 aircraft.
ALAFCO placed an order for 35 A320neo aircraft in February 2012. Airbus also received an order in February for 75 A320, including 45 A320neos from Spirit Airlines.
Norwegian ordered 100 A320neo aircraft in June 2012. Air Lease Corporation (ALC) ordered 36 A320neo aircraft during the same month.
In July 2012, UTair signed a contract to procure 20 A321 aircraft. Middle East Airlines-Air Liban (MEA) signed a Memorandum of Understanding (MoU) for five A320neo and five A321neo aircraft, with eight options during the same month.
In August 2012, China's ICBC Leasing placed an order for 50 aircraft (30 A320ceos and 20 A320neos). Philippine Airlines (PAL) placed a firm order in August 2012 for 34 A321ceo, 10 A321neo and 10 A330-300 aircraft.
The production rate of the A320 family is currently 34 a month. It is expected to rise to 42 a month in the fourth quarter of 2012.
The A320 has over 95% commonality with other members of the A320 fly-by-wire family of aircraft. The wide cabin (3.70m) allows the use of wider seats for higher standards of passenger comfort. The cabin width provides density single-class seating for up to 179 passengers or a more spacious five-abreast business-class or a four-abreast first-class seating arrangement. A typical mixed-class seating arrangement has 12 first-class and 138 economy seats.
Airbus A320 design
The A320 includes a wide single-aisle cabin of 155.5in (3.94m). It has large above head bins including fly-by-wire technology. A spacious cargo hold is provided. The aircraft is fitted with large doors to help in loading and unloading of goods.
It also consists of an ECAM (electronic centralised aircraft monitor) which gives information about the aircraft systems to the crew. Most of the A320s can be improved and upgraded to improved avionic measures. The ECAM helps in keeping the aircraft improved and upgraded even after 20 years in service.
The new winglets named "sharklets", produced by Korean Air Aerospace, are being added to A320 family from 2012. These will reduce fuel usage by approximately 3%. These will also increase the payload to 500kg and increase the range of the aircraft by 100nm at the actual payload. This also in turn reduces CO2 of 700t for each aircraft annually.
A320 flight deck
The Airbus A318 single-aisle medium range-airliner is a short bodied version of the A319.
The flight deck is fitted with two seats, one for each pilot, with primary flight and navigation displays for the Thales / VDO electronic flight and information system, (EFIS). The primary flight display shows speed, altitude and heading data. In the centre section between the pilot's and co-pilot's instrument displays are two Thales / VDO electronic central aircraft monitor displays.
The aircraft is the first subsonic commercial aircraft to be fitted with fly-by-wire controls. Instead of having a central control column and aileron wheel, each pilot has a sidestick controller.
The fly-by-wire system is supplied by Thales / SFENA. The digital fly-by-wire system is controlled by five dedicated computers.
All the primary and secondary flight controls operate by a combination of electronic signalling and hydraulic jacks. Very high safety standards were built into the flight control systems, including extensive system redundancy.
Flight envelope protection is embedded in the flight control system that will not allow manoeuvres to exceed the aircraft's structural and aerodynamic limitations. It is, for example not possible for the aircraft to exceed the designated g-limits nor to fly beyond the maximum operating speed for longer than a few seconds.
The aircraft's flight speed is maintained above the stall speed even if the pilot were holding the sidestick fully back, and the throttles are automatically opened to achieve a successful positive climb.
The aircraft is offered with two IAE V2500 engines or two CFM International CFM 56-5 developing 111kN to 120kN. The fuel tanks have a capacity of 23,860l giving the aircraft a range of 5,000km with the maximum number of passengers.
A320neo is a new engine option for A319, A320 and A321 models of the A320 family. It is expected to enter service in October 2015. It features two tons of additional payload, 500 nautical miles of additional range and better control of engine noise and emissions. The new engine options will include CFM International LEAP-X and Pratt & Whitney PW1100G. The new engines will deliver 15% more fuel savings.
The primary structures of the A320 are of composite construction with aramid fibre (AFRP), glass fibre (GFRP) and carbon fibre (CFRP) reinforced plastics. The A320 is the first subsonic aircraft to incorporate composite primary structures.
Large completed sections of the aircraft are built by EADS France (formerly Aerospatiale Matra), the Belgian Belairbus, BAE Systems, EADS Spain (formerly CASA), and EADS Germany (formerly Daimler Chrysler Aerospace Airbus).
BAE Systems has subcontracted the building of the wing root shroud box to Mitsubishi. The completed aircraft sections are transported to France for assembly.
The main cabin has two passenger doors on the port side and service doors on the starboard side. The cargo hold has a capacity of 27.69m³ and can hold bulk cargo or containers. Up to seven 46in-high LD3W containers can be carried, three in the forward hold and four in the aft hold.
