@Sylvain,
MCX exporting to AFS2 is to be used for standalone objects like aircraft, buildings, towers, buildings, etc.. and not for runway/airport systems. AFS2 requires a more complicated system of meshes, objects, decal textures and such and also using a 3D modeler like 3DStudioMax or AC3D. Take a look at the FS2 wiki about airport modeling.
