FSX Scenery--Arlanda Airport

This is a very nice thing to have, especially as the Swedflight version of ESSA is now available free of charge (http://www.rbdesign.se/swedflight.html), and this can give you a good version or Arlanda, albeit not quite current. I did have some difficulties getting this to work properly in FSX, and spent several hours trying to resolve problems - I was getting bits of snowy landscape protruding through the runways etc. I was finally able to fix this by opening the airport file provided with this version in ADE, creating a polygon 'flatten, airport background, exclude autogen' covering the entire airport, and raising the airport altitude by .2 of a meter. This seems to be important - just adding the flatten didn't fix the problem, but the flatten with the altitude adjustment did. This involved ADE adding a file in scenery\world\scenery to adjust the altitude, and a new airport file and CVX for the flatten in the main ESSA scenery folder.
