The Airbus A320 family consists of short- to medium-range, narrow-body, commercial passenger jet airliners manufactured by Airbus. The family includes the A318, A319, A320 and A321, and the ACJ business jet. Final assembly of the family in Europe takes place in Toulouse, France, and Hamburg, Germany. Since 2009, a plant in Tianjin in the People's Republic of China has also started producing aircraft for Chinese airlines.In June 2012, Airbus announced plans to begin building the 319, 320, and 321 variants in Mobile, Alabama.The aircraft family can accommodate up to 220 passengers and has a range of 3,100 to 12,000 km (1,700 to 6,500 nmi), depending on model.
The first member of the A320 family—the A320—was launched in March 1984, first flew on 22 February 1987, and was first delivered in 1988. The family was soon extended to include the A321 (first delivered 1994), the A319 (1996), and the A318 (2003). The A320 family pioneered the use of digital fly-by-wire flight control systems, as well as side-stick controls, in commercial aircraft. There has been a continuous improvement process since introduction.
On 1 December 2010, Airbus officially launched the new generation of the A320 family with the A320neo "New Engine Option".The new generation offers a choice of the CFM International LEAP-X or Pratt & Whitney PW1000G, combined with airframe improvements and the addition of winglets, named Sharklets by Airbus.
The aircraft will deliver fuel savings of up to 15%. Virgin America will be the launch customer for the aircraft in spring of 2016. As of 31 December 2011, a total of 1,196 A320neo family aircraft have been ordered by 21 airlines making it the fastest ever selling commercial aircraft.
As of December 2012, a total of 5,402 Airbus A320 family aircraft have been delivered, of which 5,234 are in service. In addition, another 3,629 airliners are on firm order. It ranked as the world's fastest-selling jet airliner family according to records from 2005 to 2007, and as the best-selling single-generation aircraft programme.The family's direct competitors are the Boeing 737, 717, 757 and the McDonnell Douglas MD-80.
#Country of origin : European consortium
#Type : Short to medium range airliner
#History :
Perhaps the most important contributor to Airbus Industrie's success as an airliner manufacturer, the four member A320 family is a significant sales success and a technological trailblazer. The 150 seat A320 is the foundation and best selling member of the family.
The A320 is perhaps best known as the first airliner to introduce a fly-by-wire flight control system - where control inputs from the pilot are transmitted to the flying surfaces by electronic signals rather than mechanical means. Apart from a small weight saving, the advantage of Airbus' fly-by-wire is that as it is computer controlled, an inbuilt flight envelope protection makes it virtually impossible to exceed certain flight parameters such as G limits and the aircraft's maximum and minimum operating speeds and angle of attack limits.
Also integral to the A320 is the advanced electronic flightdeck, with six fully integrated EFIS colour displays and innovative sidestick controllers rather than conventional control columns. The A320 also employs a relatively high percentage of composite materials compared to earlier designs. Two engines are offered, the CFM56 and IAE V2500.
The A320 program was launched in March 1982, first flight occurred on February 22 1987, while certification was awarded on February 26 1988. Launch customer Air France took delivery of its first A320 in March that year. The first V2500 engined A320 was delivered to Adria Airways in May 1989.
The initial production version was the A320-100, which was built in only small numbers before being replaced by the definitive A320-200 (certificated in November 1988) with increased max takeoff weight, greater range and winglets. The stretched A321 and shortened A319 and A318 are described separately. All four share a common pilot type rating. Mid 2000 A320 family production was at a monthly rate of 22, to be increased to 30 units a month by the end of 2002.

#SETTING THE SINGLE-AISLE STANDARDS :
The A320 is the best-selling single-aisle product
Airbus launched its best-selling single-aisle product line with the A320, which continues to set industry standards for comfort and operating economy on short- to medium-haul routes. Typically seating 150 passengers in a two-class cabin – or up to 180 in a high-density layout for low-cost and charter flights – the A320 is in widespread service around the globe on services that vary from short commuter sectors in Europe, Asia and elsewhere to trans-continental flights across the United States.
The A320’s advanced technology includes the extensive use of weight-saving composites, an optimised wing that is 20 per cent is more efficient than previous designs, a centralised fault display for easier troubleshooting and lower maintenance costs, along with Airbus’ fly-by-wire flight controls.
Advantages of the fly-by-wire controls – which were pioneered on the A320 – are many. They provide total flight envelope and airframe structural protection for improved safety and reduced pilot workload, along improved flight smoothness and stability, and fewer mechanical parts.
#COCKPIT STANDARDISATION :
In addition, fly-by-wire and cockpit standardization across the A320 Family are at the heart of Airbus’ commonality, which allows a pilot qualified on one Family member to fly them all, using the same type rating. Over 80 per cent of operators with 10 or more A320 Family jetliners in their fleets fly more than one model of the Airbus single-aisle product line – enabling them to benefit fully from the commonality concept through more effective scheduling of aircraft and crews.
Taking the Airbus commonality one step further, an A320-rated pilot can transition to any other Airbus jetliner with reduced training (known as “Cross-crew Qualification”), and is able to operate another Airbus aircraft type while still actively flying the A320 Family (a capability called “Mixed Fleet Flying”).
#RANGE IMPROVEMENTS :
Continuing its role as a pioneer, the A320 will be the first version in Airbus’ single-aisle product line to be delivered with the new “Sharklets” large wingtip devices, which are designed to enhance the eco-efficiency and payload-range performance of the A320 Family.
The Sharklets – which completed their maiden flight outfitted on Airbus’ A320 development aircraft in November 2011 – are expected to result in at least a 3.5 percent reduced fuel burn over longer sectors, corresponding to an annual reduction in CO2emissions of around 700 tonnes per aircraft. Sharklets also are incorporated in the A320neo, Airbus’ fuel-efficient new engine option which brings enhanced range for its benchmark A320 jetliner.
#SIMPLY THE BEST CABIN :
The A320’s right-sized fuselage is seven inches wider than its competitors, enhancing comfort for passengers and increasing revenue opportunities for airlines. It enables choices of four-, five-, and six-abreast layouts with wider seats, along with opportunities for wider aisles and increased overhead storage bins. Rapid turnaround times on the ground are further facilitated by the A320’s bigger passenger and service doors.
Airbus has developed a new interior for the A320 and its other family members that brings a fresh new look to the cabin, a significant increase in overhead stowage, a noticeable reduction in noise, and introduces options for ambience lighting. An added advantage is this updated interior’s lower weight.
#NAVIGATING THE FUTURE :
Advanced navigation technology contributes to the A320’s operational flexibility. This includes the Required Navigation Performance (RNP) capability, which reduces approach distances for landing while reducing fuel consumption and CO2 emissions; and the Global Position (GPS) landing system, allowing instrument-type approaches where ground stations are not available.Also offered are the Microwave Landing System (MLS) for increased approach capability in low visibility conditions; and the Future Air Navigation System (FANS) for optimised flight path and reduced aircraft spacing.
