We went playing once after school and what I recall:
735 @ 8 mile 3° glide 52k kg no relevant winds, powered controls, no LE/TE devices, manual gear, GRD spoilers, autobrakes, dry runway. Both engines f***ed out, of course.
Started with about 220 kt at the top (210 best clean but 53070 is the limit you go to 220, so that was on the heavier side) and...
...off we went at the departure end of runway at about 80 kt.
The speed was decaying very slowly, something like 2 kt per NM.
We started with the gear quite late, 2 NM I'd say and once it was down, there wasn't a whole mile left on DME. I can be making this up, but I really believe we were doing something like 185 over THR. My guess is that 4NM G/down and you live happily ever after.
The NG may be quite another story after all, especially if yours is winglet equipped.
