It's hard to imagine two aircraft so different - the Concorde and the A380. Concorde was all about speed. With only 123 seats and with an hourly fuel consumption of 26,000 litres, it was a commercial disaster. The ticket price for London/New York was something in the order of £5000 one way.
The A380 won't be a short hop plane, that's for sure. The 7E7 may well be more versatile for many routes, whereas the A380 is likely to be no more than a hub to hub plane. As long as those designated hubs have stands and taxiways to accommodate A380, is there still a problem? I know - emergency landings at a non-designated airport...
I live about 20 miles west of London Heathrow Airport (LHR), and have used this airport a great deal over the past 40 years. The runways are already working at capacity. There are two parallel east-west runways, plus another intersecting runway that isn't used very much.
It's getting to the point whereby no more take off and landing slots are available, with each runway recording a movement every minute. The only way to service the increasing passenger loadings on the existing runways is by using larger aircraft. LHR is the busiest airport in the world, and is the major hub between America and Europe.
American Airlines operates SIX flights per day from London to New York. If it could operate A380, it would need only three or four flights, thereby relieving runway slots to be used by other services. Similarly, British Airways operates TEN flights per day from London to New York - in some cases, the interval between flights is as little as 20 minutes. A380 will be able to reduce runway movements dramatically. Just as well, because a fifth terminal is being built at LHR, and as far as I know there will not be another runway.
The operating costs of the A380 are less than the costs of operating the B747 - in terms of fuel per seat per 100km.
Airbus says its aircraft is 12 per cent more fuel efficient, consuming less than three litres of fuel per passenger per 100km (62 miles), a rate "comparable to an economical family car". Operational costs overall are estimated to be 20 per cent lower per seat than the 747s.
Not surprisingly, Singapore Airlines is going to be one of the first commercial operators, beginning in 2006. Singapore is itself a hub between Europe and Australia. Also of critical importance to operators like Singapore Airlines will be the
range of the A380, which is about 10% more than the B747.
OK, you might not see many A380 flying hops over the continental US eg. Chicago to Dallas. But I don't believe the operators that use the A380 in the role for which it was designed will have any trouble at all in filling the seats.
