Tks for your advised on Taxiway, finnaly I can see it now.I have 2 question.1.-In the process of creating my project every time that I move the cursor the runway disappear and the taxiway stay.What can I do for this, 2.-Can Terramodel use Biber's models and how is recognize.3. If I create a terramodel for personal use, can I change it later to uploading in avsim.tks n' rgdsCesar

Cesar,1.- I have no idea about this one. Sometimes video card issues may cause the entire scenery to flash. But, just the runways ? Very strange.2.-YES !!! This was one of the major changes in the just released version 2.2. You can get it from the Avsim library. The documentation will explain using Biber's models (I think).3. Yes, please do.Allen
