Why don't some add-on A/C work as AI in FS9?

Hi,

AFAIK any plane that loads into FS and displays in external view can be
used as an AI aircraft. You probably made some mistake in spelling or
other error that is keeping them from showing up.

However, many flight models (aircraft.cfg and .AIR files) are not
compatible being an AI; a separate AI version may have to be created in
that case.

Hope this helps,

I've noticed that a lot of third party A/C (ones that fly
and display beautifully in external views) will not function
as AI traffic. Is this a common problem? With a simple fix?

I have added them all into my A/C database with TTools, and have
been very careful to do all that properly, and have added plenty of
examples of all types of parking (with Afcad) at my test airports.

Anybody had the same problem, and/or have a clue as to a solution?
Thanks.
