Boeing 777-8 Specs, Range, Seats, and Price

Boeing 777-8 Specs, Range, Seats, and Price – The Boeing 777-8 is a jetliner variant of the next generation 777X program designed by Boeing. The 777-8 aircraft is a follow-up effort for the development of long-haul aircraft smaller than 777-9, designed to carry 384 passengers in two class configurations and fly to a range of 16,170 km according to operator demand. The aircraft will be able to fly Sydney to London (and possibly New York) without stopping. It will have an additional range of 2,000 km more than the larger 777-9 variant.

Development of the 777-8 aircraft is currently underway. That is because the 777-9 variant should be launched in 2020 due to a 2019 flight test delay due to engine problems. Boeing has assured customers that this delay will not affect delivery schedules, even though airlines such as Lufthansa, which expects their first 777-9 delivery in December 2019, have taken emergency steps. Boeing quickly demonstrated that they were still fully committed to the Boeing 777-8 and that customers who saw the option, such as Qantas, need not worry.

A uniqueness of the 777X program is that the 777-8 aircraft has a new, longer composite wing with folded wing tips supplied by Liebherr Aerospace. Wing development based on the 787 wing but with fewer strokes. The new wing has a higher lift-to-pull ratio, aspect ratio increased from 9: 1 to 10: 1, area area increased from 436.8 to 516.7 m2, and usable fuel capacity increased from 320,863 to 350,410 lb.

Wingtip has a length of 3.5 m. The wing folding can be completed in 20 seconds and is locked at the end. Special warnings and procedures are included to deal with damage. Because existing regulations do not cover folded wingtips, the FAA issued special conditions, including proving the limits of load transport, showing the quality of handling in strong winds when raised, alerting crews when they were not in the correct position while mechanisms and controls would be carried out.

The takeoff weight of the 777-8 aircraft is around 775,000 lb like 777-300ER but it will have at least 10,000 lb of margin when introduced. Boeing estimates that the 777-8 will be 4% more fuel efficient and cost-effective than its rival, the Airbus A350-1000.

Boeing 777-8 Engine and Performance

The Boeing 777-8 will be powered by two General Electric GE9X-105B1A turbofan engines which are considered capable of generating thrust of 10,5000 lb from each engine. The highly sophisticated GEnx engine that was recently installed and rated is able to reduce significant noise. With this engine power, the 777-8 aircraft will have a maximum speed of 950 km / h, and a cruise speed of 900 km / h.

Boeing 777-8 Cabin and Interior

The internal cabin width of the Boeing 777-8 will be increased from the previous model 231 in to 235 in. The spacious cabin allows installation of 18.0 in wide seats in economy class 10-parallel configurations. The cabin will have larger windows, higher ceilings, more humidity, and reduce cabin height to 6,000 ft (1,800 m). The cabin ceiling interior features modern LED lighting.

The 777-8 is equipped with a large cabin window, which is larger than the window found on the 787, 777 and Airbus A350. In addition, the window also has a higher size, thus increasing passenger comfort when viewing, without the need to bow your head or lean at an uncomfortable angle. The window is equipped with Gentex technology which can be dimmed electronically.

Boeing 777-8 Cockpit and Avionics

The 777-8 cockpit is similar to the 787 cockpit with a large screen and front screen. The cockpit is equipped with a touch screen replacing the cursor control device and folding wingtip control. The 777X program will also feature a general cockpit and type-rating, which allows pilots to fly both of them. In addition, the 777X will feature a touch screen for entering and changing flight data and a special folding wing switch on the overhead panel.

The Boeing 777-8 will be equipped with the latest generation of Smoother Ride technology which was previously introduced in the 787 Dreamliner. Smoother Ride technology is like a stability control system in a car, which reduces the impact of turbulence when the aircraft enters airspace with changing air pressure and temperature. When a plane experiences turbulence, hundreds of sensors detect changes and provide data to a special computer that tells flight control to reduce the impact of turbulence felt by passengers.

Boeing 777-8 Price and Orders

The price of a Boeing 777-8 is US $ 394.9 million in 2018. Prices may change according to the options and configurations chosen by the operator. Because the 777-9 first flight problem was delayed, Boeing pushed back the design and development of 777-8 until at least 2021, for the first delivery in 2023 or more. The delay should not affect Boeing's participation in the Sunrise Qantas Project, for which it has proposed a 777-8 variant.
