I made an airport of my own using fsx planer. It is in Nevada. I used SbuilderX to flatten some land and I got the airport there and working. I made some traffic using planes from various websites. I deleted everything in the aircraft types .csv document and put all my new traffic in there. I put my airport in the airports.dat file. This is it:

I'm guessing there is something wrong in there because the traffic is at different airports, but not this one. What is wrong?
Yeah I know, really long runways
