Rami, I get what your saying. Yeovil's problems I bet was caused by that mesh, but when I moved the airfield file closer to the STRM mesh file on the scenery list, Yoevil stopped having the outrageous problem I was having with it. IE starting 10 feet avove the ground, then rolling and falling throug the 'runway' only to crash in to the 'ground' below it. I don't have the issue any more.
Now with Gonfirth, it has to be an airfield elevation issue because if I slew the plane left or to the right of the runway I can slew it to the ground, but if I slew the aircraft back to the runway, it pops right back up above the runway at 500FT.
Achim's the vast majority airfields over all really fit the SRTM mesh well, and Pen's airfields have no issues either. Woolston could possibly a mesh issue like Yoevil, and there I'm just floating 10ft above the runway. But with Cardiff, Gernsey, and Gonfirth I'm 200-500ft in the air above the runway. With Gonfirth I get two different locations when I select a different runway at that airfield, and by different locations I mean that on runway places me in South Britian, when I sleect the other runway it shoots me to a small Island North of the UK.
