Dreamliner Boeing 787 Specs
There are three different variations of the Boeing 787 Dreamliner and as of 31 March 2017, all three variants are flying commercially. The Boeing 787-8, 787-9 and 787-10 are described in the Boeing 787 Specs table at the bottom of this page which shows the detailed specifications of each of the types.
As well as bringing large jet ranges to a medium-sized jet, the Boeing 787 also matches the speeds of larger jets with a cruise of Mach 0.85. This is delivered with an environmentally friendly fuel saving in the area of 20% over similar-sized older airliners.
Key to delivering this efficiency is a suite of new technologies.
Boeing 787 Composites
Weight is being reduced by the fact that up to 50% of the aircraft is built using composite materials, including the fuselage and wings. To put this in perspective, compare the Boeing 787 with Boeing’s top-selling Aircraft, the Boeing 777.
|Composite Materials||50 Per Cent|
|Aluminium||20 Per Cent|
|Other Materials||30 Per Cent|
|Composite Materials||12 Per Cent|
|Aluminium||50 Per Cent|
|Other Materials||38 Per Cent|
The fuselage is constructed using single piece barrels joined end to end instead of multiple panels. This reduces the need for around 40,000—50,000 fasteners. Additionally it increased strength allowing for higher cabin pressures.
The Boeing 787 carries self-monitoring systems that are able to report to ground-based computer systems on the state of health of the aircraft and its systems. One-third of the efficiencies come from the new technology engines.
Boeing has chosen two engines to work with; the General Electric GEnx and Rolls-Royce Trent 1000. Both engines move from the old Bleed Air systems of powering aircraft systems such as air conditioning and start-up, to electrical, thus moving to a more electrical aircraft.
This is weight saving as well as less of a power drain on the engines.
Boeing 787 Dreamliner Materials Pictorial

Both engine types have an identical interface allowing operators to fit either type of engine when required.
The engine nacelles also feature chevroned trailing edges of the casing to reduce engine noise.
For the first time Pratt and Whitney have not had a launch product, as it is believed they could not make the business case work to develop this kind of engine.
An Active Gust Alleviation system, similar to the system that Boeing built for the B-2 bomber, improves ride quality. Boeing, as part of its “Quiet Technology Demonstrator Project”, experimented with several engine noise-reducing technologies for the Boeing 787.
Among these was a redesigned air inlet containing sound-absorbing materials and redesigned exhaust duct covers whose rims are tipped in a toothed pattern to allow for a quieter mixing of exhaust and outside air.
Boeing found these developments made the Boeing 787 significantly quieter both inside and out.
A special toilet has been designed to accommodate wheelchair passengers, a 56 inch by 57 inch lavatory has a movable wall so that two lavatories can be converted to one to allow access.

Which Airlines Fly The Boeing 787-10?
The Boeing 787-10 Dreamliner is the largest member of the Boeing 787 Dreamliner family. It was also the last of the three models to enter service, with the first delivery taking place to Singapore Airlines in March 2018. As such, the aircraft still has a relatively limited number of operators.

The Boeing 787-8 Dreamliner operated its first commercial flight back in 2011. This was followed by the longer Boeing 787-9 Dreamliner in 2014. Both aircraft proved popular with airlines, with over 1,300 orders between them.
The secret to the Boeing 787 Dreamliner’s fuel efficiency lies in its composite airframe and electrical flight systems, which extract less power from the engines.
It wasn’t long before Boeing launched the 787-10 in 2013. Singapore Airlines approached Boeing, ordering 30 Boeing 787-10 Dreamliners, on the condition that Boeing launched the 787-10 program.

ANA was the launch customer of the original 787 and is one of a handful of carriers that operates all three members of the aircraft family. It has so far taken delivery of two aircraft from an initial order of three placed in 2015.
However, earlier this year, the airline placed an order for 11 more of the -10, alongside one more -9. While its original 787 orders were for aircraft with the Rolls-Royce Trent 1000 engine, this year’s orders are for GE engined aircraft.

British Airways is another one of the handful of carriers operating all three types of Dreamliner. It was due to receive its first 787-10 in January. However, the date kept sliding back.
The airline finally took its first 787-10 on June 26th, with the second following three days later. The aircraft made its debut carrying freight due to the enormous deficit in passenger numbers.
BA is expecting 12 787-10s.
Etihad has an order for 30 787-10s placed in 2013. It took its first delivery in 2018 and has so far taken eight -10s, including the special greenliner liveried aircraft in January of this year. The next aircraft to be delivered was A6-BMI in October. This aircraft made headlines as it was used in Boeing’s ecoDemonstrator program before delivery.

EVA air placed an order for four 787-9s and 14 -10s in November 2015. So far, it has taken delivery of six of the largest Dreamliner, with the first arriving in the fleet on June 19th, 2019. The most recent delivery took place on September 30th of this year.
As the world’s oldest continuous airline, KLM couldn’t miss out on the largest member of the Dreamliner family. It had intended to split its 787-10 order with sister airline Air France. However, the two agreed that KLM would take the remaining 787 deliveries, while Air France would take the entire Airbus A350 order. 14 787-10s on order, KLM has so far accepted five aircraft.
Saudia is unique as the only airline to have received its entire Boeing 787-10 order. The airline placed an order for five of the aircraft in December 2008. The fifth aircraft was delivered to it on October 13th. However, it didn’t end up flying to its new home until the end of the month after a technical problem delayed its Charleston departure.

As a result of its order for 30 Boeing 787-10 Dreamliners, Singapore Airlines became the type’s launch customer. Singapore Airlines received the first Boeing 787-10 Dreamliner, now registered 9V-SCA, on March 14th, 2018, according to Planespotters.net.
The airline chose to fit the aircraft with 301 economy seats and 36 business class seats for a total capacity of 337. Of its initial order of 30 Boeing 787-10 Dreamliners, Singapore Airlines has currently received 15 aircraft. Indeed, the airline hasn’t received a new 787-10 for almost a year.

Third in line to receive the Boeing 787-10 Dreamliner was United Airlines. On November 5th, 2018, United received the first of a total order of 14 of the type. Six more orders were delivered in June 2013.
It now has 13 aircraft, each fitted with its Polaris business class seats. Only two have been delivered so far in 2020. Interestingly, United became the first airline in the world to operate all three of the 787 Dreamliner models when the 787-10 Dreamliner entered service with the airline before planned back in late 2018.

Last but not least is Vietnam Airlines who, according to Boeing’s most recent order book, hasn’t ordered the type. According to Planespotters.net, the airline’s four 787-10s are leased from Air Lease Corporation, meaning they were almost certainly from ALC’s order for 25 787-10s placed in September 2013.
