ai aircraft and seeing them

I'm trying to get some commuter ai's installed which aren't included in any of woai packages.  I'm wondering if the ai aircraft (mostly aig btw) should show up in the current aircraft folder in fsx?  I have been trying to use AIFP3 to install the aircraft as well as the flight plans and I'm not sure I'm doing it right.  I placed the ai aircraft in my aircraft folder along with the flyable planes.
