St. Helena Island

[concordski]

St. Helena is a small island in the middle of the atlantic ocean, roughly halfway between Africa and South America. Until recently there was no plan for an aerodrome on the island, which means that it is one of the most isolated communities on earth. Its nearest landfall is ascension island, some 600 miles to the north, home to a UK/USA airbase. Now however, there are plans to build an airport on the island.

To find out more about the island go here

The plan is to build an airport of small municipal capacity, with a runway of 2250 metres (around 7000ft), and to build small scale airport facilities, with an apron of about 3, and a small terminal.
Because of the lack of flat land on the island, and its remoteness, construction will be very difficult. The airport will cost

i was thinking that some of your data may be wrong, i may be wrong but if St Maarten has a R/W of 7535ft and can handle A340s and 747s then how would a 7000ft r/w only be able to take A321s and 727, surely 767s and A330s will be able to use a r/w that size with the appropriate flap levels.

just a thought

No, there's no problem with my data. I'm not sure why though, thats a very good point.
The ground at prosperous bay plain would probably be able to take it, and the airport is at only a few hundred feet above sea level. It's probably the parking gates and the taxiways and the width of the runway that are the problem. Still, any offers to create this cool scenery?

Are you sure that 747's and A340's can use this runway?
Probably with 10 lbs of fuel and one passenger!!  A fuly loaded 747 needs 10,000ft minimum. In this case there is an enormous gap between Vr and V1.
With the rwy's quoted in this thread  747's would have to stand on their brakes and declare V1 at about 80kts!!!.
Methinks it would be better to equip them with floats i  8)

Well yes, as we all know a fully laden 747 cannot take off from St. Maarten, which is why KLM fly them in with 50 empty seats and via Curacao.
