If you want this aircraft to use for AI, you have to change aircraft.cfg and fsp_a320.air.
But if you changed, this aircraft would not be suitable for flying by yourself.
So I strongly recommend you may copy original folder,then rename ,for example ,AI_AC_fsp_a319 ,it.
Now you have two folders,one original,another for AI, so you change for AI folder's aircraft.cfg and fsp_a320.air.
I hope you enjoy.
Many thanks for hiro who made cfg and air.
