I can't confirm if its a bug nor a program to the AI. I've use my fighter plane with a good maneuvability. The AI folowed the plane but it didn't shoot at below 1.0 miles. The crosshair was pointing to it but the AI (my plane) didnt do anyting except it just follow it. After that chase my plane went slow and the range goes 1.0 increasing, then thats the time the AI started to shoot. I think I'm not just the only one.
P.S. Notice it
