Down at the bottom of Africa we are upgrading to Eurocat X radar system, which includes a simulator.
I know the IT boffins have loaded a lot of data relevant to aircraft performance for the sim and it is very real. Apparantly they got the info from Janes (!) - they have all the aircraft data on electronic file and our company bought it and it has been downloaded into the sim.
You might like to contact them - -dont ask me for an address, but i am sure you can get hold of it via their website.
