Scoggs,
Thanks for the feedback, the figures which I quoted are from the B747-400 Operations Manual page PI.10.28 dated October 01,1999.
The data is based on:
1: Actual (unfactored) landing distance.
2: Includes distances from 50 feet above threshold.
3: Assumes max manual braking.
I wouldn’t expect to see a B747 of any model operating off runways of that length, but the figures in the QRH are there for when you HAVE to land.
Thanks for setting me straight on the leading edge flaps. With leading edge flaps on the 747, leading edge slats on the 757 / 777 and both leading edge flaps and slats on the 737-200, I’m starting to get confused!!!
