Hi all. Something seems whacky with a lot of my smaller airports lately. At many of them, the ground around the general area is all raised up, maybe like 30-50 feet, and a few other times, the aiport seems to be down in a pit. I have added nothing to do with terrain in ages so I guess it is nothing new I added. Has anyone else had this problem, or know anything about it? Thanks Rick

This can happen with add-on terrain mesh installed. Airports and any other fixed elevtion polys (lakes, rivers) do not adjust to match the new (more accurate) terrain elevation/profile. It's most noticable at small airports.

While payware mesh usually includes corrected elevations for airports and other fixed elevations, freeware mesh normally does not.

Hi. I did get some USA add on mesh from here a long time ago, but I guess it just took awhile to find the affected airports. Have to live with it I guess. One thing tho, would an add on US mesh affect airports in Canada too? I seem to have probs in both countries. Thanks for your replies. Rick

I've seen this before, except it was the airfields which were 100ft+ above its surrounds.

Is this Canada in general, or only those near the add-on mesh areas?

It should only affect airports within the coverage area of the mesh add-on. Add-on mesh does not necessarily 'respect' borders, so if the mesh is near the border it may well extend across the border.

Well, so far the Canadian aiports have all been in the west, and probably close to being within 100 miles of the border.
