How does the 777X folding wing work?
A quick flip from vertical (fold) to horizontal (extend) starts the process. At the tip of the 777X’s carbon fiber wings, a hydraulic actuator rotates the tips to their inflight position. Once in place, electrical locking mechanisms, which only disengage when powered, hold the tips in place to fly.
Why does the 777X have folding wingtips?
Airport access The first and most important reason to add the folding mechanism to the wingtips was so that the giant bird could access a greater range of airports. Its huge 235 ft 5 in wingspan is a full 11 feet longer than its predecessor, making it too wide to land at a Code E airport.
How long are the folding wing tips of 777X?
Folding wingtips. Measures 14.75″ length. Wingspan (extended): 14 in. Wingspan (folded): 12.5 in.
Why do 777 not have winglets?
For example, Boeing’s hot-selling 777 wide-body airliner does not have winglets. According to Gregg, that’s because the 777 operates from international terminals designed for larger jumbo jets. As a result, Boeing found the performance it was seeking without the need for vertical extensions.
Does the Boeing 777X have MCAS?
Boeing stated that the 777X does not have an equivalent of the Maneuvering Characteristics Augmentation System (MCAS) that is installed on the 737 MAX and that played a role in two crashes.

Are folding wings Safe?
FAA CONCERNS “With wingtips in the folded position, the conventional airplane-wingtip-position lights may have reduced visibility due to the upward position of the wingtips, possibly impacting ground-operation safety.
What airplanes have folding wings?
The Boeing 777 (classic) twinjet wide-body airliner was offered with folding wingtips for confined airports. The new Boeing 777X models feature a shorter and simpler folding wingtip than was planned for the earlier Boeing 777.
Is 747 better than Airbus?
Looking at cargo capacity, the Boeing 747 has more capacity despite having less powerful engines and less thrust. Airbus has leaned hard into serving passengers and let Boeing slip ahead for this category. Additionally, we do have to admit that a cargo version of the Boeing 747 exists, and it is quite popular.
Does the Boeing 777 have a folded wingtip?
Boeing did, in fact, offer large folding wingtips on the 777 when it was first launched, in order for it to fit at smaller gates, however, no airlines purchased this option. Folded wings have been used by the military for decades. Photo: US Navy
Will the Boeing 777X fit in a regular airport?
As the folding wingtips of the new 777X make it able to fit into regular widebody airports and stands, it means it has a footprint that is consistent with that of the previous generation. With the wingtips folded, the profile of the 777X is roughly the same as the 777 classic during taxi and gate operations.
What will the 777X’s wings look like?
As Simple Flying reported last year, the 777X’s wings will be based on the design of those of the 787. The striking wing sweep on the Dreamliner makes it very easily recognizable compared to Boeing’s older designs. The ‘raked’ design of the 787’s wings has a similar function to winglets.
Why does Boeing use blended winglets on the 777X?
As part of its design of the 777X and its new wings, Boeing found the folding tip required 3% less block fuel compared to a wing with a blended winglet that truncated the span at Code E dimensions. The company has tried to make the system fit as seamlessly into existing operations as possible.
