Did a search on this topic, but couldn't find much, so posting this question. Now using PF3 which has a great feature, using AI traffic to generate ATC chatter in the program. What I have noticed, since I am now flying only GA aircraft on my sim, and have been using GA AI only, is that I get almost zero PF3 ai chatter. If I turn on some airline traffic in MT 6, then I get AI chatter through PF3, which is almost entirely chatter with airliners. Now I go to an airport, that I live near, KPDK, which has a great deal of GA traffic in real life, and I see static aircraft from MT6, but almost none of them are active on the airport. So if they aren't active, then of course there is no ai communication on tower, clearance, or ground radio freqs. My question is twofold, the first part asking, do you experience a similar situation with GA lack of activity at Airports with MT6, if you use MT 6? The second part of the question, is , with PF3, do you find that almost all the chatter is from airliners, versus GA AI?
