Can 777X fly with wings folded?
The aircraft’s design is intriguing: Folding wingtips will let the 777X fit at existing airport gates while still giving the wings the lift they need. The new Boeing 777X features wingtips that fold up.
Why does the 777X have folding wingtips?
The main reason for the wingtips’ mechanical folding feature is to allow the aircraft to land at more airports. Putting the 777X in group VI (with a wingspan of 214′ – 262′) would have given its operators the same headache as Hi Fly, and narrowed their choice of routes and airports significantly.

Why are there no winglets on a 777?
Why does the 777 not have winglets? One reason that the 777 does not feature such wingtip extensions is the operational limits these would place on the aircraft. The 777-200LR and -300ER variants of the aircraft have a wingspan of 64.8 meters. This would cause the aircraft to be classified under aerodrome code F.
Do winglets increase lift?
Winglets increase an aircraft’s operating efficiency by reducing what is called induced drag at the tips of the wings. This unequal pressure creates lift across the upper surface and the aircraft is able to leave the ground and fly.
Will the 777X be Cancelled?

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.
Where is the Boeing 777 upright build system?
The Fuselage Automated Upright Build (FAUB) system was developed and quietly tested in Anacortes, Washington, 40 miles north of the 777 Everett assembly plant. A major leap in automated production, it drills the tens of thousands of holes in the fuselage more quickly, accurately, and safely.
