>> reporter: we're flying on a flight simulator in hayward, california. >> we're coming in at 137 knots this is what their view out the window would have looked like that thoday on the 777. at a certain point here the pilot disconnects the auto pilot this is common because it allows the crew to continue to maintain proficiency in flying the airport as opposeed to auto pilot operations. >> reporter: but it can be done. you can land without doing anything? >> if you wanted to, this airplane would land itself and stop without touching a button. >> reporter: an electronic guide system was out of commission when the plane crashed but on a perfectly clear day, four lights on the side of the a runway give the dguidance you need. when two are red and two are white, it's perfect. >> if i see all red, i'm too low.
