My initial question was about, how to have in mind an order of magnitude of the likely acceleration stop distance, a Boeing 777-300 would need at full load.
As i wrote earlier you either can find out by looking into your FCOM(where you get Vspeeds) under take off field lengh REQUIRED.
Or in the AFM and im quite sure the ASD is one of the graphs in it.
Are you a B777 pilot or not?do you have those manuals?.
I had in mind, that a B777-200ER at roughly 200 Tons, would need at the same conditions listed above, 1300 Meters (4200 ft), right ?
A B777-200(trent 892 engines) at 270T 30C,SL,flaps 15,will need 7820 ft asd with a balanced V1 and a 780 ft STOP margin.(toda=asda=9500m).
At 200t,about 4800ft for a balanced V1.
