The prior note about the auto pilot is how the real 727-100 works. The 727-200 had a newer type auto pilot that was much better than the -100.

As for the Flight Director??? I don't think it does much. I tried hand flying the ILS using the F/D and it never did anything but mirror what ever the ADI was doing. When I would fly left or right of the LOC or above or below the G/S it never gave a command to correct me either in G/S AUTO or MAN. In the real 727 the "yellow bird" as it was called was a superb flight director that was very stable and easy to fly.
