I seem to be haveing a problem when I set the weather to quite poor. If I have the vis down to say 1/2 mile, all the autogen, trees, and airport enviroment etc.. are nicely obscured, HOWEVER, the ground still is clear as day! That really kills the illusion of a poor vis day and needless to say makes finding the airport way to easy when I would like to have to fly it to minimums. Any ideas would help. Thanks.
