This article on the new Aerbus A380 is correct in that it will fly within standard conditions, given all of the simulations Aerbus has run. What I am not sure will pass muster is whether the airline industry will be receptive to a business model that relies on larger units to cental locations rather than smaller units over a distributed area. Home town example: I have had the misfortune to have to go to LAX for flights and to play chauffer for friends and family. I have also done the same at Burbank Airport, no more than forty miles away. Everything is different as night and day, from parking to lines. With other small airports in the area (John Wayne and Ontario) people in the LA area are more likely to get a flight for travel than if LAX were the only option.
So I am sceptical about the A380. Obviously the intent is to move more people in the same number of flights, but that does not count the peripheral costs of having to deal with more people coming through already congested hub airports. That and I am not a fan of government subsidy of the airline industry. Boeing have been taking a beating, but things are looking up. I wonder just how much European pride drove the A380's development as opposed to engineering and economic considerations.
