773 runs out of wing, think of the 779 as the cross between the load hauling of the 744 and the wing/efficiency of the 787.

773 has 115k engines. 779 has 105k engines. Both have a mgtow of 775k. It’s possible because the 779 has a larger, higher aspect ratio wing. Induced drag is inversely proportional to aspect ratio. Less drag and more lift equals less thrust required for takeoff. A more efficient airplane but will the 779 be under powered like the 773 is under winged? Footage of the first 779 flight was cool, it seemed like it barely rotated and was airborne.

Not under powered. The new wing will fix most of the 300ER's woes.

The basic airframe of the 777-9 is lighter because of the carbon wing. Lighter airframe, better payload/fuel capacity with heavier loads and better range.

The more efficient wing will carry the same weight, with less power needed.

If we cut a deal with Boeing on the Max debacle, I'd much rather see an order for the new 777's as opposed to more 300ER's.

Now, if they would just get us a radar that actually works in auto….instead of being called scary mode.

😂😂😂😂😂😂......snorted my coffee up my nose on that one.......good one Dave!
