What @killbilly said but to add that on the 73 at least there’d be no need to rerun numbers. Deleting the assumed temp in the FMC makes it a max thrust takeoff and our performance data always comes with those numbers. That said, we’d have no idea where on the runway we’d unstick except for a vague idea based on weight.500 hour pilot question. Don't taze me. But aren't you supposed to take off before or after a heavy jet t/o point, to avoid that? I know that you said that you were heavy, but could you have ran the numbers to takeoff at a higher thrust output, to take off before their rotation and fly above the 767's wake?
