Hi Michael - yes I have used this a few times, it is pretty useful sometimes. I also have the VFR Photographic scenery installed on flight sim which is excellent. The problem with the airfields (or any field) is that they change colour periodically throughout the year. In the summer there are lots of bright yellow ones (don't know the names of any flowers

) - also, when there is broken cloud, sometimes the sun can appear to highlight a particular area a lot more and viceversa
