Why is 777X wingtip folding?
To combat the issue, Boeing created the folding mechanism that reduces the wingspan to 212 feet and 9 inches — the length of the 777’s wings. This allows the 777X to fit into gates capable of fitting the current 777 models.
Does Boeing 777 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.
Will the 777X fail?
The agency said it wants Boeing to “implement a robust process so similar escape will not happen in the future and this is not a systemic issue.” The FAA said in its letter certification date for the 777X “is realistically going to be mid to late 2023 (>2 years from now).”
Is Boeing 777 the biggest plane?
It is the world’s largest twinjet. The 777 was designed to bridge the gap between Boeing’s other wide body airplanes, the twin-engined 767 and quad-engined 747, and to replace older DC-10s and L-1011 trijets….

Why does b777 have no winglets?
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 only just falls below the upper limit for the ICAO’s aerodrome code E.
Can 777X fly with wings folded?
The 777X can still fly and land with one or both wingtips folded. The biggest concern would be for one or both of the wingtips to fail (fold) during takeoff.
Is MCAS necessary?
In early 2020, the FAA, Transport Canada, and EASA evaluated flight test results with MCAS disabled, and suggested that the MAX might not have needed MCAS at all. The FAA began requiring all MAX pilots to undergo MCAS-related training in flight simulators by 2021.
Will Boeing cancel the 777X?
Boeing cuts its 777X backlog by more than a third after pushing back deliveries until 2023. Boeing last week said deliveries of the 777X would be delayed until late 2023. The large twin-engine jet is the company’s newest plane. The longer planes are delayed, the easier it is for customers to cancel orders.
Is 777X certified?
The FAA said in its letter certification date for the 777X “is realistically going to be mid to late 2023 (>2 years from now.” Boeing Chief Executive Dave Calhoun said earlier this month that “we are still confident” it will be certified in the fourth quarter of 2023.
What is Boeing’s biggest jet?
The 747-8 is the world’s longest currently-operational passenger airliner, surpassing the Airbus A340-600 by 3.1 ft (0.95 m). With a maximum take-off weight of 975,000 lb (442 t), the 747-8 is the heaviest aircraft, commercial or military, manufactured in the U.S.
