When opening an airport in AFCAD 2.11, ALL the airports, including the original ones, are marked as MOD, and none are marked as STOCK. I had expected the untouched ones to be STOCK. Is this correct?Joe

Yes, that is correct.

So, if the untouched ones are also "Mod", which airports would qualify as "Stock"?Joe

Hi,This isn't what happens to me. If I enter the code of an airport I've already modified, then I see two listings, one MOD and one STOCK. If I open a new airport, I only see a STOCK listing.I assume you are saving all your modified airports into the Addon Scenery/Scenery folder, and that the Addon Scenery layer is activated in the Scenery Library?Hope this helps,--Tom GibsonCal Classic Propliner Page: http://www.calclassic.comFreeflight Design Shop: http://www.freeflightdesign.comDrop by! ___x_x_(")_x_x___

Tom,I have attached a picture of the screen showing KJFK. The top one is the Flight 1 AFCAD download. The bottom one must be the original that I have never touched. Both say MOD.http://forums.avsim.net/user_files/50816.gif
