Is it possible to have AI aircraft flying on a dogfight map ?

Yes m8, but you can only fly them on external view (after you've picked a 'Flyable') and only if the host server has them in his Plane Set

The other interpretation of your question is:

No, it is not possible to have AI-controlled aircraft on a dogfight server.

As HotSpace said, there is a way to set things up so humans can fly (from an external view) aircraft that are normally AI-only aircraft. But it isn't possible to have AI pilots flying planes on a dogfight server.

Many thanks.
