The Airbus A380 - known for many years during its development phase as the Airbus A3XX - will be the largest airliner in the world by a substantial margin when it enters service. Currently under construction, first flight is scheduled for 2005, with deliveries to start in 2006. Launch customers include Emirates Airlines, Singapore Airlines, Air France, Qantas, Virgin Atlantic, Korean Air and ILFC.
Neither manufacturer could afford the enormous capital cost of developing an all-new airliner, especially one of A380 size, unless there was a reasonable expectation of having exclusive access to the market segment - and yet neither could afford not to develop a 600-seater if the other did. To do nothing would be to cede market leadership to the competition.
The initial advantage was with Boeing. Boeing's 747, although designed in the 1960s, had been kept up-to-date and was larger than Airbus' largest jet, the A340. For many airlines, the extra size of the 747 made that type a "must buy" for their highest density routes, and the cost advantages of fleet commonality were an incentive to buy smaller Boeings as well. There was room to stretch the 747-400 and still retain reasonable seat-mile costs, while the A340, as an already-stretched version of the twin-jet A330, was approaching its upper limit.
After years of design studies and airline surveys, Airbus finally made the decision to go ahead with the $US10.7 billion A380 project in 1999. The design strategy was carefully crafted. Merely by being very large, the A380 could achieve much better seat-mile costs than any other aircraft (just as the 747 had done in 1969). Because the A340 wing was too small to be efficient at the sort of gross weights required for a 600-seater, an all-new design was needed. Given that the cost of starting from scratch was necessary in any case, Airbus chose not to select a wing that would be optimally efficient at around the 600 tonne maximum gross weight of the A380, but to aim it at the 750 tonne class instead. In doing this they sacrificed some fuel efficiency (because the A380 wing is too big for it) but the sheer size of the design coupled with the incremental advances in technology over the years still allows Airbus to claim 15% better economics than a 747 or an A340. The payoff for Airbus is that it will be a relatively easy task to make still bigger versions of the A380 which will reach their optimum cost-efficiency somewhere around the 700 to 800 passenger mark - close to twice the size of a 747-400.
For Boeing, the announcement of the A380 was a major blow: already faced with heavy expenditure to replace the aging mid-sized 767 line, Boeing were then placed in the awkward position of having to replace their flagship 747 as well, or else cede market leadership to Europe. Boeing's first action was to announce the Sonic Cruiser concept - a 767-sized near-sonic aircraft that would compete on speed instead of size and economics, but a general lack of market interest has seen this project cancelled. Boeing has announced a plan to replace the 767, but their intentions in the over 400-seat market remain unknown.
Despite the cyclical downturn that first gripped the airline industry in 2001, the A380 has been ordered by nine airlines so far. Perhaps more significantly, Airbus holds a substantial order from the giant aircraft leasing company IFLC, which indicates that industry analysts expect airline demand for aircraft in this size class to be strong in the later years of the decade. Current firm A380 orders stand at 103, including 17 freighter versions. Break-even is estimated to be around 250 to 300 units. Emirates have ordered over 42 of these airframes.
Initial publicity, particularly from the airlines which have ordered it, has stressed the ability of the A380 to provide increased room and comfort, with open space areas to be used as relaxation space, bars, duty free shops, and the like. Historically, the same type of prediction has always been made when a new, larger aircraft is announced - the 747 is an obvious example - but the economics of airline operation are such that the extra space is nearly always used for additional seating. Given the history of the air transport industry to date, the key change that the A380 will bring to travellers is not extra comfort or lavish in-flight facilities, but more of the same difference that the 747 made - more seats and lower seat-mile costs.
