A380 - some questions

[CLW_aviator]

Hello,

I would like to know what are the required runway dimensions (length, but I`d also like to know width if possible) for A380? I mean how long should a runway be to provide a SAFE take - off or landing. What airports are CURRENTLY ready to accept this plane, especially are JFK, FRA and NRT ready? And, what about boarding or deboarding the plane, how long would it take approximately? Would it be possible to board passengers of both its decks at the same time?

The A380's FAA takeoff field length is 9,350ft compared to 10,900 ft. the 744ER.

The A380 is designed to operate under Code F requirements but has the ability to operate in a Code E (747) airport.

It will indeed be possible to board/un. both decks at the same time. Several airports have planned three jetways for each A380 gates.

just check the airbus a380 websites there are pictures of the A380 with a boarding bridge to each of the desks

Takeoff and landing distances are not the problem. Field performance is quite good, which is not surprising considering the huge wing. It's taxiway width, and turn radius which are the problems.
If the 380 misses the last taxiway, at many airports it may cause a substantial delays to other traffic whilst it is "backed and filled" around.

I understand a "taxi" camera has been installed to help keep the 380 on narrow taxiways.

I never thought of that one!!! That would cause some serious problems at an airport like JFK or LHR especially if you only have 1 or 2 active runways!! Keep in mind that airports may have more than long enough runway for the A380 to land, however, it's up to the pilots to set her down in the right spot so they don't use the whole runway. If they did use the whole runway, I'm sure ATC will have something to say to those pilots!!

Absolutely agree here. The fillets are the problem...

Well, anytime an aircraft misses the last TWY you gonna have a problem...
A smaller one with a Dash which will simply turn around in the RWY, but still you will have some discontinued approaches during rush hour...

The A380's FAA takeoff field length is 9,350ft compared to 10,900 ft. the 744ER.

Does it take account of the flight test results (landing speed about 4 knots less than expected 137 knots)?

I think A380 prefers runways 60 metres wide, not 45. There are issues about outboard engines ingesting thrash. Also, wingtip collisions with fixed structures or planes on taxiways.

Also, wingtip collisions with fixed structures or planes on taxiways.

How should that be? If a aircraft holding short of the RWY where the A380 is landing is only close to the wingtip of the A380, it's a long way over the stopbar.

Thanks a lot for your help. But, about the landing, what are the required runway dimensions? I mean I know that if it can take off, it can also land on a runway, but what is the exact distance that A380 needs for landing?

And, is JFK ready to accept the plane? What about NRT, FRA and LHR?

Thanks.

A big difference between Airbus 380 and Boeing 747-400 is that Airbus 380 has a wingspan over 15 metres wider. So the safety margin for passing obstacles is 8 metres less for Airbus following the same centerline as B747. This may matter for safety.
