Boeing has revealed new details about the passenger experience it is creating for the 777X, its newest long-haul, twin-aisle jet family.

The manufacturer announced at the Farnborough International Airshow 2014 on July 15 that it would apply Boeing 787 Dreamliner cabin innovations to the interior of the Boeing 777X family.


Boeing plans to apply cabin innovations developed for the 787 to the 777X family, its updated versions of the original 777 family. But when Boeing first announced in July 2014 the 787-like cabin innovations it intended to adopt in the 777X, it was not clear how the company could adopt some of those innovations for a metal-fuselage aircraft in which corrosion would be possible and which would be less resistant to high cabin pressure than the 787. The 787 and competing Airbus A350 XWB are able to offer features (all planned for the 777X) such as a lower cabin altitude, larger cabin windows and higher cabin humidity levels because they have corrosion-proof, highly pressure-resistant fuselages made entirely from carbon-fiber composite materials

“We’re already getting very positive feedback from our customers about the 777X’s design concepts, and we think passengers’ preference for the 777-300ER and 787 will continue with the 777X,” says Bob Feldmann, vice president and general manager, 777X program for Boeing Commercial Airplanes.

According to  the manufacturer, among its cabin-design advances, the Boeing 777X interior will feature:

● A cabin altitude of 6,000 feet –  the same as is that offered by the Boeing Sky Interior in the 787 Dreamliner;

● Cabin windows that Boeing says will be more than 15 per cent larger than those of the competition and located higher on the fuselage so they are at eye level for a larger percentage of passengers. The competition to which the company refers is presumably the similarly sized, in-house Boeing 747-8 Intercontinental and 777-300ER, and the larger Airbus A380: all these aircraft have metal fuselages. However, like the Boeing 787, the competing Airbus A350-1000 has an all-composite, highly pressure-resistant fuselage capable of holding much larger windows than a metal-fuselage aircraft and is expected to have cabin windows at least as big as those in the composite-fuselage 787 and in the 777X ‒ which has a metal fuselage;

● Increased ambient light made possible by the larger, newly positioned windows;

● A new cabin interior design that allows airlines to customize the architectures of the cabins of different seat classes. This innovation includes an adaptable suite of parts that facilitates choices in overhead ceiling and stow bin configurations, allowing airlines to create the feeling of separate and distinct cabins that meet both airline and passenger needs, according to Boeing;

● A cabin that is 16 inches wider than the unnamed competition, allowing airlines a variety of economy class seat widths up to 18 inches wide;

● Higher cabin humidity, comparable to that in the non-corroding, composite-fuselage Boeing 787 (and in the competing, composite-fuselage Airbus A350 XWB family). It isn’t clear how Boeing will be able to offer higher cabin humidity in a metal-fuselage aircraft family, because of the corrosion problems higher humidity levels cause;

● Enhanced air filtration, incorporating the latest filtration technologies to increase passengers’ well-being;

● Next-generation LED lighting, to enhance the passenger experience throughout the flight and allow airlines “more branding opportunities”, according to Boeing; and

● Lower cabin noise, achieved through a new engine nacelle design, new high-bypass ratio engines, better insulation and a passenger cabin that doubles the number of air nozzles with lower velocity and less noise.

In addition to these advances, Boeing says it is continuing to explore new ways to create a better flying experience.

“With key development ahead, the 777X will incorporate state-of-the art interior design and technologies,” says Dennis Eng, director, 777X Interiors, for Boeing Commercial Airplanes. “The 777X will redefine the total passenger experience. All of the interior features we are exploring and designing into the new airplane are working together as a package to create an exciting new passenger experience.”

To date, Boeing has won orders and commitments for 300 Boeing 777X aircraft from six customers worldwide. Production is set to begin in 2017, with first delivery targeted for 2020.

Most 777X-family orders to date have been for the Boeing 777-9X, but the manufacturer has won some orders for the shorter, ultra-long-range Boeing 777-8X.
