I have MY Traffic and works fine exept I see this at many airports. Airplanes submerged halfway under the ground or sometimes floating with the wheels a few feet above the ground. This mostly occurs with add on scenery but also sometimes on the default airports. Only AI planes affected.

Many posts about this on AVSIM forums. The fix depends on whether you are using FS2002 or FS2004. I can't remember the routine for the former, but in FS2004, you need to use JABBGL, (available here on Avsim, search for 'jabbgl_134445.zip'), a small utility by Jacky Brouze which allows you to edit the relevant scenery files and make small adjustments, enabling you to correct the problem. If you don't fancy doing this yourself, maybe you could post a list of the affected airports and other simmers might send you the relevant edited bgls. If you are finding the problem at payware airports I suggest looking for patches available or if not contact the author. I would also suggest checking out other posts on Avsim for further enlightenment on this irritating issue.

Will try that, thanks Jennifer.

The other solution which seems to work for some situations is that if you are using a separate AFCAD2 file for the airport (in FS2004), to make a copy of it and put the copy in [fs9]sceneryworldscenery.I've used that routine several times and it has worked.Cheers,Ian P.

Never tried that one Ian! Must give it a go.

Thanks Ian, that worked for my Fly Tampa KMIA, and KSFO. Kansai (Osaka,Japan), which was originally FS2002 scenery with updated afcad still has some planes dug in the ground. This scenery has other problems like building crashes in the middle of the runway. I always have to turn off crash detection when I fly there. So maybe an artifact of that particular scenery. Will have to try Jabbgl to fix that one as is very nice freeware.

Yeh, I'd say try Ian's method first, because it's much simpler and if it doesn't work for a particular scenery then go with Jaabgl.

I can't claim credit for inventing it... I think it might have been Peter McLelland, but if it was someone else, my apologies and please feel free to correct me! :-hahGlad it worked.Cheers,Ian P.

As previous posters have indicated, if AI are OK in most airports, but float/sink in some, it is probably because the default airport AP9 file is set at one altitude, and there is an active AFCAD file for that airport set at a different altitude. This can be for airports, runways, and or starts. This is often the case when an addon airport is used, where the scenery objects are set at a different flatten altitude than the default. The AFCAD file is then adjusted to the visual scenery, but the default altitude is still used for certain things, like starting out AI. (MS: Fix this in FSX!)It has been determined by others that a copy of the AFCAD is not needed (and probably not desired). All that is needed is the XML airport element code, with correct altitude set. This code is compiled with the SDK BGLComp to create a small .bgl file. The recommendation seems to be to place this in the scenerygenericscenery folder, though I have placed them in the same directory as the default AP9 file with success.JabBGL is good for inspecting altitudes in AP9 files. It is not recommended that you use it to edit the default files, since for example if you delete the addon scenery, you would have to remember to edit back the default AP9 file. scott s..

"...JabBGL is good for inspecting altitudes in AP9 files.

However, as you rightly point out, you'd have to remember to place them back in the secenery folder if you uninstalled the addon scenery.
