I asked a few pages ago if this a/c could weigh itself and calculate the trim. No reply. Relevant to the above I'll ask again.
Next answer I'd like is what the thrust setting was at TOGA and if it was not max was it increased at any time during the roll.
Boeing have a procedure if not yet at Vr approaching the end of TORA. Do AB's?
Do the computers have a say in the matter if you try to get airborne below Vr? If so, what happens? e.g. reduced pitch angle? but can you become airborne? Useful if in pilot's judgement it is safer to struggle into the air with dexterous finesse and ground effect rather than become a steaming burning hulk at the end of TODA.
