You might have heard about this spanish Valencia freeware already. Here is a short focus. Distributed by Akesoft (http://www.ake-airlines.es/akesoft/LEVC-X/, the file is 65 mb heavy, is for FSX and FS 2004 and has an automated installation. On FSX, the folder can be transfer from Programfiles to your FSX scenery\addon scenery\ folder. We don't know much things about the team behind this project although it is supported by the spanish (IVAO) VA airlines Ake-Airlines.
The photo-like ground textures equals good paywares and the airport is fully depicted with its main terminal, gates, jetways and cargos aeras, plus the Air Nostrum hangar. Are still missing though, some industrial plateforms and surrounding houses but the project is maybe unfinished. I have just one regret about the FSX defaut roads traffic that has not been removed or adapted to the airport. A few textures are flikering but once again, this might be my own settings (i am using Nvidia inspector now). Akesoft works with 3DS MAX and Photoshop. This promising team already announced new projects : Vitoria LEVT, San Sebastian LESO (oh yeah! ), Reus LERS, Girona LEGE and Pamplona LEPP.
