A380 Takeoff/Landing Performance Requirments

[OverRun]

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).

The $US costs to upgrade an adequate and fairly recent 747 airport to A380 ops are something like (I do hope I don't upset people):

runway length $0
runway strength $0 (for the next 8 years of ops anyway)
...... add $10 mill if your consultants are good at the mumbo-jumbo or are a big firm
...... and/or add $10 mill if the present runway is a bit stuffed
runway widening from a 45m runway $8 mill
...... but any half-wit project manager can add another $10 mill to this
taxiway widening $3 mill
aerobridge/gate $2 mill
...... per gate
terminal $2 mill
...... add $20 mill if your present terminal is older than your mother-in-law
...... add another $10 mill if your airport directors have grandious visions

EXTRAS
if your airport CEO is a women - add $10 mill
....... and/or if your airport organisation structure has the legal dept ranking as high as the ops dept - add $10 mill
......third world - add 40% (divided equally between higher costs and bribes)

BTW - I've been doing the A380 airport upgrade thing - my contractors start building in March 06.
