ATC Sims
Heya,
I was also looking for a good ATC Sim, reading the previous posts, I think i will stick to VATSIM, it may not be 100% correct, but it's close enough! I also have ATC Simulator, which is for US Tracons only, and even with speech recognition, not that good. It certainly gives you a challenge on DFW App though, and if your not a fast typer...dont try it!
