AI take control of the plane question?

I know this is a long shot but I read a post somewhere and someone was saying in X-Plane there is a facility to let AI fly your plane, you can be at the start, middle or near the end and if you click on it AI takes over.

This does work because I have XP11, the thing it does in XP is if for example you go from EGLL-EHAM and you click the AI, it does not go to EHAM it picks a random airport and flies and lands there.

Anyway the post I read was a guy was asking if there was anything like it for FSX, he got a reply saying someone had done a mod to enable this and posted a link, course it was an old thread and the link took me to a page of the guy who did the mod but he left a message saying because of ill health he no longer supports or updates this program.

So my question: Has anybody got or tried this prgram by any chance and can upload it or pass it on, I'm interested?
