In FSX I have the feeling that the FS9 trees that are used are displayed at a higher scale than in FS9. So it's probably more a fault at the design, or compatibillity, stage. I found they overhung the threshold at one end. When I get time I'll do a bit of pruning! Gerry Winskill OK Gerry thanks. I think that at this particular strip, at the range when the markers should become visible, they are hidden by trees. Frank T.
