Air Nav Question

Hello Fellow SimmersJust a recent customer of AirNav,and looking for a little advise.I have noticed that the program uses both MT AI, default AI and of course FSLive.In order to decrease the size of aircraft which was populating the larger airports I made the MT AI Bgl.pasive leaving FSLive as is.I now notice a sharpe decrease in aircraft at the airports which was what I was striving for except when checking the flight schedules for the major airports, the FSLive aircraft do not show up on the schedules all the time.Should I be using the MT aircraft in conjunction with the FSLive aircraft.Thanking for advise.Kenny G.
