:-wave Several times I found the Phrase AI while downloading airplanes for FS2004. And they are not visible in the aircraft list. What can I do to make this visible, and what is AI standing for.CU Carel48

AI stands for Artificial Intelligence. It's a phrase used for the planes other than the one you are flying that are flying around in the world with you.Normally you wouldn't want to fly these planes because of a simplified air file and the low quality of the models, thus being framerate-friendly.
