I guess that is about right, the distance is about another hour of flying and that is around the fuel burn you would expect end of a flight. Isn't the range delta from higher MTOW extra fuel determined by the fuel flow at the beginning of the flight? ( You add range at the front so to speak and not...Jump to post
The 787-10 can't do it because it has the 787-8 wing. It can't do it because it doesn't have the TOW. simplistic. More TOW would just move the wing loading through the roof with a vengeance.

Maybe it is in relation to the 77W, the A350-1000 lifts more and flies further than the 77W, I was not there. This is probably as simple as anywhere beyond MZFW range (@308tMTOW) you gain a tradeoff "area" spanned by those 8t more MTOW. Any combination of more payload plus more fuel that ...Jump to post

For a similar shaped wing a ~10% bigger span would create a ~20% lower wing loading and ~30% more wing tank fuel capacity. However that means a new wing, which would have a different modern design optimized for longer range and higher speed. https://lh3.googleusercontent.com/-_j4C3nag8vk/WVuAfvK3u8...Jump to post
