I know that many of the modern jets can 'land' themselves, but I was wondering how much can they do without the pilots touching anything. I assume it can descend and get in line with the runway on its own, but can the plane pull the nose up, reduce the speed, touchdown at the right place on the runway, pull the nose back down, and slow down all be itself. If so, what instrument would be in use (I know the autopilot, more specific). I just saw a movie and that is exactly what happened. The plane in movie was a 747.
