Traffic AI in Airport?

I would like to put AI traffic on an airfield built by me.

I want to know how to set the path (taxiway, tarmac, runway) on the airfield so that the AI plane must follow ?

follow the SDK instructions on how to build airports. You need Runways, Taxiways and parkings. Best is to place them all according to real life. The internal AI system will do the rest.
