Interesting replies, thanks!
The generic landing data show's <1900m with Max autobrake and MLW s feasible, and considerably less using the manual braking tables.
Just feels very uncomfortable ..
Anyone used Max Auotbrake on the 744? I've only used 4 but would imagine Max is like dropping an anchor?
(PS : Yeah ... CBG/Cambridge UK @ 1892m ... but would imagine at just over ZFW not up to MLW ... mostly 747's in there are for re-fits at Marshalls).
