a) On a widebody with a reasonable amount of airframe hours and a decent passenger load, I’d be surprised if the *actual* weight of the aircraft was within a couple of tons either way of what you thought it was.
That may be true. You may already be a couple of tonne
overweight. There are some margins built into the take-off performance calculations to allow for unknown variations, I'm not about to intentionally use up those margins with a known variation.
d) Even if I was worried, I certainly wouldn’t ride the brakes on an above-idle thrust setting. Just when you might need all of the braking performance, you deliberately remove some of it? Much rather take +500kg with cold brakes, thank you!
There is another option you know? Just park somewhere and wait for the fuel to burn off.
