I must have a bad mesh file somewhere and I was hoping that someone might have encountered this same problem. The area around my Cleveland area is loaded with elevated lakes, hills, airports, etc. My Cleveland airport by Ansari is also elevated! The city of Cleveland sits next to a huge cliff! What terrible sights! I am using PA mesh, which I removed and it did not solve the problem. Anyone have this problem?Thanks!Airbus

I discovered some very interesting points in Alaska. Since I have R. Taburet's entire USA 38m suite installed, I at first thought that was the reason. Wrong, 'cause even after de-activating every add-on scenery in my config file, some lakes/streams/roads are still on plateaus, and some mountains are cut off by streams, thus forming unexpected steep and high cliffs. Must be a general problem in FS at some places.Nevertheless AFCADs can cause elevated/sunken airports/airstrips (you can correct this in AFCAD by entering a more reasonable altitude), and some places need flatten/exclude switches (but this is a harder thing to do).Others can't be corrected, I think...Andreas

Andreas,I just did a scan of all my AFCADs using a utility called scanAFD. Although it found duplicates, none of them were in the Cleveland area. I am going to look some more and maybe use trial and error to find the bad file.Thanks!Airbus

Howdy,if all your airports and lakes reside on mesas then you're dealing with a faulty mesh file. If only airports but not lakes are on plateaus then it's a faulty flatten switch, which may be part of a scenery add-on.There are a few known add-on mesh files that have these problems and you may have installed them in FS9Scenerybasescenery or FS9worldscenery or FS9addonscenery, which some designers recommend (and I don't, for the reason you're experiencing right now). Sort any of these folders by date and have a closer look at large files with a date more recent than May 2003.Rob Gainer's original versions of his mesh files are known for these kinds of problems (his Alaska mesh file flattens all of North America!) and, I believe, there's also a Ontario mesh file by David Voogd that creates widespread plateau issues in parts of the US.Good luck with your hunt!
