What makes the 777X special?
The most unique aspect of the 777X is undoubtedly its wing design. These new wings are built with carbon composites and are 71.75 meters in length (235.4 ft). This allows for more aerodynamic efficiency, some amount of wing flex, and significant fuel savings.
How much does a Boeing 777X cost?

| Range | Up to 8,730 nmi (16,170 km) | 7,285 nmi (13,500 km) |
Why are the wings of the Boeing 777X so big?
Boeing describes the wings of the 777X as having an ‘optimized span’. In plain English, this means that it’s bigger, and therefore more efficient. Folded out, the huge size of the 777X’s wings translates to a marked improvement in fuel burn, something which all airlines are always keen to achieve.
Why are there no longer any biplanes in flight?
Overall, though, the above makes them suited only to aerobatics, which can also be performed by monoplanes. Advances in wing design and composite materials take away most of the advantages of a biplane for any other use: ie actually travelling (the main purpose of an aeroplane) and carrying a load.
Which is more efficient a biplane or a monoplane?
Overall, then, they’re more complex than a monoplane, less efficient, and aren’t much more manoeuverable. They have more disadvantages than advantages.
Why was there a biplane in World War 2?
There were a few leftover biplanes in WWII – The Fairey Swordfish torpedo bomber was one of the most widely used, as the low speed and good lift from the biplane design allowed it to carry a heavy torpedo, while the drag issues didn’t matter at the slow speeds they needed to fly to be able to release…
