i'm using mainly PAI AC, now, I can't use them if I have Rafcad airports since they have the same mdl file. Sure I can clone the model folder and assign one for each airline but that will involve hours of tedious tweaking. Maybe there is some more elgant way to go about this?after all, adding all these folders will break the concept behind PAI.will appreciate any help.

Use AITM to change the aircraft radius and set up the model files. It's almost painless.

Yes, using AITM, it only takes a few seconds to set each one up. You just go to each aircraft, enter the airline code in the box for Model file and enter the radius for the airline. AITM does the rest.Matt
