Does anyone know which airports in the mainland US it will be limited to?

I'm pretty sure it's going to need a long runway that can sustain the kind of weight that aircraft is going to need.

should be interesting when they start flight testing that thing.....

Actually, the A380 will not need a longer runway than the 747. Also note that the weight of the plane will be distributed among more tires than on the 747, meaning the plane will not need 'stronger' runways. The taxiways will need to be widened in a number of airports though.

I think that in terms of runway the A380 should be able to land wherever a 747 can. That does not say anything about taxiways and gates though.

To expand on what Scorpio said, the A380 will be able to land anywhere a 744 can.

3 factors:
- Pavement loading - The same or less than 744. 22 tires as opposed to the 744s 18.
- Runway length - The same or less than 744.
- Exhaust plume length - Less than 773.

Taxiway widening will not so much be on straightaways, but in tight turns extra material needs to be added on the inside of the turns.


The BIG limiter will be gate space. The wingspan is almost 80 metres and you basically need two jetways for loading/unloading.


EDIT: napalmed the spelling mistake

Well JFK has said they are planning renovations.

ATL is getting a new INTL terminal, so I am thinking it would be built to accomodate it.

I can only assume DFW would make plans for it at its new Intl terminal.

Just read in Flight International that the pavement loading for the A380 will be a little bit higher than the B744 ( 26,500 A380 against 23,300 B744 ), but lower than the B773 ( 26,600 ) the figure is weight per wheel. This is the main gear wheels only as they carry 95% of the weight.
It was earlier mentioned that LAX is lagging behind the other mainland US airports getting ready to receive the A380, mainly JFK and soon Memphis for FEDEX

Taxiway bridges well have to be examined. when all 20 main gear are on the bridge the 95% of the weight will be distributed on the bridge, so they will have to make sure they can withstand the weight.

KIAH... can easily support the A380... in terms of Taxiway's and runways... it takes the AN124 once a week.

IMO i think that any airport with DUAL jetways... such as EDDF that have 2 ramps to the plane will be able to support the A380.

Runways will not be a problem for A380, at least not compared to B777-300ER/B747-400.


Weight per wheel comparison:
A380-800: 26,500 kg per wheel [20 wheels]
A380-800F: 28,100 kg per wheel [20 wheels]
B747-400: 23,300 kg per wheel [16 wheels]
B777-300ER: 26,600 kg per wheel [12 wheels]
Note: number of wheels is main gear only. Assuming nose gear supports less than 5% of total weight.



Runway performance of the A380 is at least equal or better than 747.
Airbus has published the following data on the A380 take-off performance.
Mind you, take-off performance is highly dependent on pressure altitude:

Source: http://www.airbus.com
A380-843F MTOW limitation for RR Trent 977 powered models, ISA conditions
9500 ft runway, MTOW:
0 ft press alt: 593 ton
2000 ft: 562 ton
4000 ft: 536 ton
6000 ft: 505 ton

10000 ft runway, MTOW:
0 ft press alt: 604 ton
2000 ft: 576 ton
4000 ft: 546 ton
6000 ft: 519 ton

11000 ft runway, MTOW:
0 ft press alt: 626 ton
2000 ft: 596 ton
4000 ft: 567 ton
6000 ft: 537 ton

12000 ft runway, MTOW:
0 ft press alt: 636 ton
2000 ft: 607 ton
4000 ft: 579 ton
6000 ft: 548 ton

1 ton = 1,000 kg = 2,200 lb

Note that above figures are aerodynamic/thrust margins, not actual/structural limits. The A380F is currently structurally limited to 590 ton MTOW. This would mean that the A380F would be able to take off WITHOUT payload/fuel penalty at MTOW from a 9500 ft runway at ISA sea level conditions [sea level, 15 degrees C, 59 F]. The A380F looks to be a very good airplane in terms of take-off performance. If a 747 can do the job at MTOW, the A380 will also be able to do the job at MTOW from the same runway.

Great info. guys.....I wonder how many airports are going to invest more $$$ to acomodate that aircraft.

I can see the following US aiports making the change:

JFK
LAX
DFW

That's about it in my opinion.....Maybe Honolulu?

Also, which routes do you see that aircraft utilizing? Paris ->JFK, Heathrow->JFK etc....
