Hi there,after hours of (unsuccessful) research I would like for a kind simmer to help me out with an everlasting problem I have, unfortunately, with one of my favorite airports KPHL.I've read through numerous posts here and in other forums and nothing helped me cure my bouncing aircraft problem. In this instance my aircraft bounces at KPHL on rwy 27L exactly when crossing taxiway "U".I've tried several AFCAD's, even removing add-on scenery to no avail. I've scanned for duplicate and faulty AFCAD's and don't have any. I've read many times that other scenery even far away could possibly interfere, but I just don't want to give up on all my add-on sceneries I've collected over the years and uninstalling one after another, after another.Is there really no other way to isolate/cure this problem?Any help would be greatly appreciated,Peterhttp://members.aol.com/pzsoulman/myhomepage/logo.gifAMD64-3400,1GB/3200DDRAM,WinXP(SP2),DirectX9.0c,Geforce6800(128MB)(Det.84.21), CH Yoke/Pedals

Not enough info! Is this the default KPHL or an addon? (Simflyers?) What other addon scenery are you using in that area? UTUSA? FSG Mesh? etc...

Oops, yep that info might be usefull ;-)I'm using default KPHL, no mesh but the problem still remains having tried out several AFCAD's, including no add-on AFCAD's.Cheers,Peterhttp://members.aol.com/pzsoulman/myhomepage/logo.gifAMD64-3400,1GB/3200DDRAM,WinXP(SP2),DirectX9.0c,Geforce6800(128MB)(Det.84.21), CH Yoke/Pedals

Hi,AFCAD's typically don't fix this problem. Try adding a flatten bgl or flatten line to your scenery.cfg file.This is for FS98/2000 but still works the same way:http://www.microsoft.com/games/flightsimul...neryobjects.aspHope this helps,--Tom GibsonCal Classic Propliner Page: http://www.calclassic.comFreeflight Design Shop: http://www.freeflightdesign.comDrop by! ___x_x_(")_x_x___
