No one disputes that aborting past V1 might result in a stop past your calculated balance field length...although the argument could be made that my using TRs, better braking technique, soaking up manufacturer's fudge factor......vs the 200 hour pay to fly guy you have in your plane might result in my stopping at the end and you going into a lake of lava at the end....
But that said....if my balanced field equals the runway...a very rare condition that only lives in the world people who run derated/assumed thrust or people who routinely fly jets, heavy, in and out of short runways....
I have to tell you..that I would take my chances with a post V1 RTO if prior to rotation, if I saw some Tali-ban with an RPG a few taxi ways back, then heard an explosion in my tail......
Not an unrealistic scenario to consider, if your flying around Iraq and Afghanistan these days.....
