I should think there would be no problem using any aircraft. I also us AIFP. It should just be a matter of getting the desired aircraft saved in the aircraft.txt file. Myself, I am enjoying the A2A/Shockwave Wings of Power 2 WW2 Fighters box set, and the Jets and Bombers box set, but both are out of production. I use those older models because they are less complicated and won't bog my system down. I specifically look for old FS2004 models, preferrably without a VC, to use only as AI aircraft for my traffic.BGL. They make nice eye candy without a big hit on my computer. I'm not sure you would benefit from using accu-sim aircraft as AI traffic. The better sound would be nice up close, but they are complicated models to have filling up your skies. Just a thought...
