Re: 787-10 range

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. Keesje is correct in stating that the 787-10 has the wing of the 228t 788 :-) the 787-9 was supposed to get ...

Re: Operational Weak Spots of the Airbus A321NEO/LR.

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...
