Ergo.. max power take offs, would burn up less runway to V1, meaning more runway for a post V1 RTO......vs... a reduced thrust take off....
but continuous use of full thrust will add to the likelyhood of an RTO; it really all depends on what is limiting but usually the plane but the kinetic energy build up with acceleration on a jet is rapid and is not linear but would be proportional to the square of the velocity...

and even if the rwy length were not limiting it may become limiting or excessive and dangerous, just a few knots from V1 and at a limiting V1...your stopping technique [ especially if there's no RTO autobrake/auto spoiler selection] must be test pilot perfect AT V1...and honestly whatever side you are on it takes lots of faith in the performance analysis...and from reading here the FAA leaves a lot to be desired in terms of both ASDA, TODA and flight path protection...It would be nice if everyone were as cautious as the performance experts who frequent this forum

RTOs after V1 should never become a 'routine' in lieu and such decisions are best reserved for dire catastrophe as described by others, there have been precedents of course were such a decision did save lives but it resulted from pilot error and it there was no choice it was luck and everyone knows that Hawkers a built very very tough


it seems you have improved your approach to us here...I hope
