I'd like to apologize if this has been covered but I couldn't find what I need to know with a quick search. Could anyone tell me whether or not it is possible to assign an FSX/FS2004 'operational' aircraft as an AI aircraft.

Suppose that I have a specific aircraft already loaded on my FS that I would like to have fly in formation with another specific aircraft already loaded on my FS. Has anyone tried this?

Many thanks...
