Boeing has whipped the (very long) covers off the latest addition to the Dreamliner family. The 787-10 was launched during President Trump's visit to the Boeing factory in South Carolina, and blends the outstanding fuel efficiency of the existing 787-8 and 787-9 with room for even more passengers.
Compared to the existing 787-9, the 787-10 has gone through a fairly serious growth spurt. The new plane is 18 feet (5.5 meters) longer, which helps free space for 330 passengers in a two-class cabin, a 14 percent improvement over the 290-passenger 787-9. Boeing also says there's also room for 15 percent more cargo than before, giving airlines even more space to overcharge for baggage they'll inevitably break.
Maximum range is now pegged at 6,430 nautical miles (7,400 mi/11,910 km) which is a not-insignificant 1,205 nautical miles (1,387 mi/2,232 km) less than the 787-9 can manage. You can blame that on the extra capacity and size, both of which are the enemies of efficiency.
Although it can't match the smaller members of the Dreamliner family, the 787-10 is still much more efficient than planes of a similar size. Boeing says its new model uses up to 10 percent less fuel than its nearest competitor, and 25 percent less than the planes it's likely to replace. Not only does that represent a significant cost saving for airlines, it also should help cut emissions across the whole industry, something that benefits everyone.
"This airplane, the most efficient in its class, is the result of years of hard work and dedication from our Boeing teammates, suppliers and community partners in South Carolina and across the globe," says Kevin McAllister, Boeing Commercial Airplanes president and CEO. "We know our customers, including launch customer Singapore Airlines, are going to love what the 787-10 will do for their fleets, and we can't wait to see them fly it."
The new Dreamliner will be arriving with airlines in 2018 and, given that Boeing has already received 149 orders, they shouldn't be hard to spot at the world's airports. The plane will make its maiden flight in the coming weeks.

VincentWolf. I can't wait for batteries with an energy density double that of liquid fuels (at least double is needed because as a liquid fueled aircraft burns fue it becomes lighter, therefore needing less energy to fly at a lower angle of attack (or the same energy to go faster).
I think I will be waiting a while yet.
OR we could use high energy density flow batteries with open loop electrolyte use (discharge to environment), that will give a new look to contrails -probably no saving as bromine based electrolytes are expensive and resources need to be mined.
I'm sort of disappointed with the idea of a bigger 787. One of the things I like about the plane is that it's smaller than the bigger, less personal ones. I thought the point of the 787 was smaller airplanes flying in smaller airports and not having to endure huge hubs.
