Also something I remember is a button that said "land me" or something like that, and the computer would attempt to land it and it had speech on top telling you what was going on, it was like a trainer telling you what to do, its unrealistic but it would be cool to have.
Also I think there should be AI crashes, like a slight chance that someone screws up and destroys the plane on a runway and they have to shut it down until its cleaned up. Also the ability to declare emergencies with the "ATC" (I air quote as the FSX ATC its terrible) and have all other planes go around while you emergency land.
I also say this while strolling through the forums, was AI carriers Ops and Free Flight carriers (like in the airport page show the carrier and have a sub menu pop up to choose where the carrier is located and its course, or to have it randomly choose the course).
Also what would be cool is if ALL of the ground vehicles at the airport interacted with you (IE Catoring Truck, luggage, pushback, shuttles, those stair things when you don't have a jetway, etc).
I know this is like my first post and its a long list but I've been on FSX for 3-4 years (and 98 for an additional 1-2
