According to the documentation supplied by Sim-Wings for this FSX package, “High resolution ground textures based on an aerial image as well as Autogen cover the whole island. A custom 3D Mesh Terrain has been created for the airport featuring an underpass and a sloped car park.” Compatibility is also built-in for most major terrain mesh products, AESLite provides some life and the scenery also sports custom night lighting that the developers hope will give you a definite “wow” factor.

Users of P3D may like to know that the package is also compatible with that simulator, in combination with customised files. Check the manual – linked from the product page – for details.
