I am trying to add AI traffic to U42 (Salt Lake City Mun No 2) airport. I have added the tower, tower and ground freq. (already has taxiways and parking)Do I have to add the airport to the airports.txt file, and if so where do I get the elevation data? (I have tried using the center point of the airport showed in AFCAD, but the compiler says the elevation format is bad). Also would I list it as U42?Thanks in advance for any help!!Paulhttp://www.advdigitalmedia.com/sig.jpg
