In the summer of 1988, a group of Airbus engineers led by Jean Roeder began working in secret on the development of a ultra-high-capacity airliner (UHCA), both to complete its own range of products and to break the dominance that Boeing had enjoyed in this market segment since the early 1970s with its 747. McDonnell Douglas unsuccessfully offered its smaller, double-deck MD-12 concept for sale. Roeder was given approval for further evaluations of the UHCA after a formal presentation to the President and CEO in June 1990. The project was announced at the 1990 Farnborough Air Show, with the stated goal of 15% lower operating costs than the 747-400. Airbus organized four teams of designers, one from each of its EADS partners (Aérospatiale, DaimlerChrysler Aerospace, British Aerospace, EADS CASA) to propose new technologies for its future aircraft designs. The designs would be presented in 1992 and the most competitive designs would be used.

In June 1994, Airbus began developing its own very large airliner, designated the A3XX. Airbus considered several designs, including an odd side-by-side combination of two fuselages from the A340, which was Airbus’s largest jet at the time. The A3XX was pitted against the VLCT study and Boeing’s own New Large Aircraft successor to the 747. From 1997 to 2000, as the East Asian financial crisis darkened the market outlook, Airbus refined its design, targeting a 15 to 20 percent reduction in operating costs over the existing Boeing 747-400. The A3XX design converged on a double-decker layout that provided more passenger volume than a traditional single-deck design.

On 19 December 2000, the supervisory board of newly restructured Airbus voted to launch a €8.8-billion program to build the A3XX, re-christened as the A380, with 50 firm orders from six launch customers. The A380 designation was a break from previous Airbus families, which had progressed sequentially from A300 to A340. It was chosen because the number 8 resembles the double-deck cross section, and is a lucky number in some Asian countries where the aircraft was being marketed. The aircraft’s configuration was finalized in early 2001, and manufacturing of the first A380 wing box component started on 23 January 2002. The development cost of the A380 had grown to €11 billion when the first aircraft was completed.

Initial production of the A380 was troubled by delays attributed to the 530 km (330 mi) of wiring in each aircraft. Airbus cited as underlying causes the complexity of the cabin wiring (100,000 wires and 40,300 connectors), its concurrent design and production, the high degree of customization for each airline, and failures of configuration management and change control. Specifically, it would appear that German and Spanish Airbus facilities continued to use CATIA version 4, while British and French sites migrated to version 5. This caused overall configuration management problems, at least in part because wiring harnesses manufactured using aluminum rather than copper conductors necessitated special design rules including non-standard dimensions and bend radii; these were not easily transferred between versions of the software.

Airbus announced the first delay in June 2005 and notified airlines that deliveries would be delayed by six months. This reduced the number of planned deliveries by the end of 2009 from about 120 to 90–100. On 13 June 2006, Airbus announced a second delay, with the delivery schedule undergoing an additional shift of six to seven months. Although the first delivery was still planned before the end of 2006, deliveries in 2007 would drop to only 9 aircraft, and deliveries by the end of 2009 would be cut to 70–80 aircraft. The announcement caused a 26% drop in the share price of Airbus's parent, EADS, and led to the departure of EADS CEO Noël Forgeard, Airbus CEO Gustav Humbert, and A380 program manager Charles Champion. On 3 October 2006, upon completion of a review of the A380 program, the CEO of Airbus, Christian Streiff, announced a third delay, pushing the first delivery to October 2007, to be followed by 13 deliveries in 2008, 25 in 2009, and the full production rate of 45 aircraft per year in 2010. The delay also increased the earnings shortfall projected by Airbus through 2010 to €4.8 billion.

The A380 can be fitted with two types of engines: A380-841, A380-842 and A380-843F with Rolls-Royce Trent 900, and the A380-861 and A380-863F with Engine Alliance GP7000 turbofans. The Trent 900 is a derivative of the Trent 800, and the GP7000 has roots from the GE90 and PW4000. The Trent 900 core is a scaled version of the Trent 500, but incorporates the swept fan technology of the stillborn Trent 8104. The GP7200 has a GE90-derived core and PW4090-derived fan and low-pressure turbo-machinery. Only two of the four engines are fitted with thrust reversers.

In 2005, the ICAO recommended that provisional separation criteria for the A380 on takeoff and landing be substantially greater than for the 747 because preliminary flight test data suggested a stronger wake turbulence. These criteria were in effect while the ICAO's wake vortex steering group, with representatives from the JAA, Eurocontrol, the FAA, and Airbus, refined its 3-year study of the issue with additional flight testing. In September 2006, the working group presented its first conclusions to the ICAO.

In November 2006, the ICAO issued new interim recommendations. Replacing a blanket 10 nautical miles (19 km) separation for aircraft trailing an A380 during approach, the new distances were 6 nmi (11 km), 8 nmi (15 km) and 10 nmi (19 km) respectively for non-A380 "Heavy", "Medium", and "Light" ICAO aircraft categories. These compared with the 4 nmi (7.4 km), 5 nmi (9.3 km) and 6 nmi (11 km) spacing applicable to other "Heavy" aircraft. Another A380 following an A380 should maintain a separation of 4 nmi (7.4 km). On departure behind an A380, non-A380 "Heavy" aircraft are required to wait two minutes, and "Medium"/"Light" aircraft three minutes for time based operations. The ICAO also recommends that pilots append the term "Super" to the aircraft's callsign when initiating communication with air traffic control, in order to distinguish the A380 from "Heavy" aircraft.

In August 2008, the ICAO issued revised approach separations of 4 nmi (7.4 km) for Super (another A380), 6 nmi (11 km) for Heavy, 7 nmi (13 km) for medium/small, and 8 nmi (15 km) for light.

Variants

The A380-800 original configuration carried 555 passengers in a three-class configuration or 853 passengers (538 on the main deck and 315 on the upper deck) in a single-class economy configuration. In May 2007 Airbus began marketing a configuration with 30 fewer passengers, now 525 passengers in three classes, traded for 370 km (200 nmi) more range, to better reflect trends in premium class accommodation. The design range for the -800 model is 15,200 km (8,200 nmi). The second model, the A380-800F freighter, would carry 150 tonnes of cargo 10,400 km (5,600 nmi). The -800F development was put on hold as Airbus prioritized the passenger version and all cargo orders were canceled. Future variants may include an A380-900 stretch seating about 656 passengers (or up to 960 passengers in an all economy configuration) and an extended range version with the same passenger capacity as the A380-800.

From 2012, Airbus will offer, as an option, improved maximum take-off weight, thus providing a better payload/range performance. The option was introduced in order to counter a perceived strength of the 747-8I, the latest revision of the Boeing 747. The precise size of the increase in maximum take-off weight is still unknown. British Airways and Emirates will be the first customers to receive this new option.

In November 2007, Airbus top sales executive and chief operating officer John Leahy confirmed plans for an enlarged variant, the A380-900, which would be slightly longer than the A380-800 (79.4–73 m or 260–240 ft). This version would have a seating capacity of 650 passengers in standard configuration, and approximately 900 passengers in economy-only configuration. The development of the A380-900 is planned to start once production of the A380-800 variant reaches 40 planes per year, expected to be in 2010. Given this timeline, the first A380-900s could be delivered to customers around 2015, about the same time as the A380-800F (freighter variant). Airlines that have expressed interest in the model include Emirates, Virgin Atlantic, Cathay Pacific, Air France-KLM, Lufthansa, Kingfisher Airlines, as well as the leasing company ILFC.
