I was experimenting with the autopilot on the 747. I got the plane down to 100 feet flying over the flats of India at just above stall speed, maybe 180knots. I then went out over the ocean and sped up to 500 Knots while holding this altitude. The plane was fine until I sped up time to 16x. At that speed it would porpoise in and out of the water, submerging all four engines and the nose up to the black mark. It didn't get damaged from this until I tried it going over land where it impacted.
It also looks pretty good to be 200 feet off the ground going 500 knots and then change the heading ninety degrees. The plane banks very nicely at 16x.
If you ask me they messed up the sensation of speed with this game a little bit. Going 500knots 100 feet off the ground doesn't look much different than it does when I'm driving at 65. I might believe I'm going 200 when looking out the 747's windows at this speed, but not 500.
Also, does anyone know the difference between knots and MPH? It seems like there is a slight difference. I don't really know why the flying industry bothers with this. Why not just use MPH or Kilometers per hour instead of this ancient seagoing unit?
