The only real issue I see with the 7X is the folding wingtip bit. I really don't see it as a safety of flight issue, I just see it as added
complexity, and something new the airlines are going to have to learn to deal with. The overall design should be a fairly easy one for them.
The numbers they're tossing out there are very impressive as well. The 777-9X would stretch the 300ER by adding four frames, but would have a 21%
improvement in per seat fuel burn, and a 16% in cost per seat over the 300ER. The 8X would be a 10 frame stretch of the 200ER, but would have a
derated engine at 88,000 lbs of thrust, as opposed to the 99,500 lb engines of the 9X. The third possible variant is the 8LX, which is a shrink of
the 9X, with a similar take off weight (795,000 lbs), but would have a range that is 85 nm longer than the 200LR
It's probably going to have an alloy frame under the skin, with a redesigned fairing where the wing joins the fuselage, as well as an extended
horizontal stabilizer. They are looking at carving the sidewall, to add 4 inches to the cabin width to keep the current 10 abreast seating in coach,
and 9 in premium, but to give a little more room.
The cockpit would have a 60% commonality with current 777/787 aircraft, which would cut transition time down from 5 days, to 2.5 days.
So it's basically a very similar aircraft to the 777 you see out there, as far as looks go, with newer materials under the skin.
See if this link works. It goes into detail about the changes.
