And Gordon, that's why he's called goose:hehe:
Vulcan, I just read A380s need 3300 metres to take off, can we snap the runways together??

There is so much complexity in the A380 performance, which has to include a proper route analysis, that it is impossible to speak so simply. But in the event that you don't mind being wrong but want to start somewhere:
MTOW 560 000 kgs
Takeoff distance at MTOW, Trents, 300', 30 degC = 2800 m
MLW 386 000 kgs
Landing distance at MLW, Trents, 300', 1900 m
LCN +/- 120 on the wing gear
Runway and taxiway width - far too complex. Group F. Runway 60m width plus all the rest of shoulders, blast etc. Taxiway - hey its gonna fall off many of the exisitng taxiways on the corners.
Summary - think 747 (apart from the pavement widths) and you'll cover much of it. Try this in real life and you'll go broke because the A380 is so finely tuned in the economics field (unlike the 747).
I would suggest the minimum runway length be at least 3500m, which caters for 747 long range ops and allows for the inevitable weight growth of the A380. Plus being a new facility, you’ll need the 240m RESAs beyond the strip end. All up, 4100m of length is desirable, although it can be done in 3400m for the 2800m runway.
An all new runway is actually much cheaper to build (per sq.m.). The 60m runway, shoulders, RESAs, parallel taxiway, widened taxiway turning fillets (also designed for the difficult to fit A340-600), connect to existing taxiway system, and providing enough taxiway exits (including a couple of high speed ones) so as to have good runway capacity: - US $52 million construction cost. Consulting fees and supervision and charges $8-10 million. Add US$10 million for earthworks (making the ground smooth and level) for an easy site or up to $50 mill if there are big amounts of filling and cutting to be done. Add in the terminal and gate upgrade costs. Add in the various factors mentioned above. That gives a feel for project basic cost to which a prudent person adds a contingency of 15-25%.
