Why is the Boeing 787 so special?

The 787 was designed to be the first production airliner with the fuselage comprising one-piece composite barrel sections instead of the multiple aluminum sheets and some 50,000 fasteners used on existing aircraft. Boeing selected two new engines to power the 787, the Rolls-Royce Trent 1000 and General Electric GEnx.

Fuel efficiency: the Boeing 787-8 boasts exceptional fuel efficiency, thanks to its aerodynamic design, advanced engines and use of lightweight composite materials. It offers approximately 20% lower fuel consumption per seat compared to older aircraft models, reducing operating costs and environmental impact.

The Boeing 787 is known to be a more comfortable and efficient aircraft than the 747, especially for long-haul flights. There are objective differences between both planes. The 787 has newer engines, two fewer of them and more electrical (rather than hydraulic) systems, which means much less cabin noise.

MORE DETAILS

Passengers comfort Generally speaking, the Boeing 777 offers a more comfortable passenger experience. This is because it is somewhat larger than the 787 and has higher capacity, leading to more room in terms of seating comfort.

The Dreamliner is a successful aircraft, still in production with more than 1600 delivered or on order. The list price for a new Boeing 787-8 is $239 million dollars. Yet even as international travel opens again for these long-range aircraft, two Dreamliners barely ten years old are waiting for the wrecker's ball.

The 787's latest problem mirrors production issues discovered over 2020 and 2021 that included improperly fitted shimming that led to paper-thin gaps between surfaces on the Dreamliner's fuselage.

The carbon-fibre structure of the 787 allows the aircraft to be pressurized to a much higher level than on many other aircraft types. The lower the cabin altitude, the better you feel both during and after the flight, allowing your body to adjust to your new time zone more quickly.

The Air Inside The cabin pressure on the 787 is higher and the humidity higher than other airplanes. Basically, passengers on board will feel like they are at an altitude of 6,000 feet, 2,000 feet lower than a standard flight.

“In reviewing certification records, Boeing discovered an analysis error by our supplier related to the 787 forward pressure bulkhead,” said the company, referring to the portion of a plane at its nose that maintains the pressurized conditions in the cabin.

This is quite probably the reason for the popularity of the mid-sized Boeing 787-9 Dreamliner, which offers its operators a very useful balance of both range and capacity. This mirrors the Boeing 737 MAX family, whereby the MAX 8 model (which is the second-largest of four variants) is by far the most popular version.

The sound comes from the rotary hydraulic motor situated in the wheel well of the jet which turns the drive shaft for the flap drive screw jacks.

The Bottom Line: The Airbus A350-900 and Boeing 787-9 are very similar aircraft, suited for similar missions. As one would expect, the slightly larger A350-900 has a seat-mile cost advantage, while the 787-9 has an advantage in cost per block hour. These aircraft are competitive, and nearly tie in economic performance.

MORE DETAILS

It has been reported that the A350 is quieter than the B787, primarily due to the automatic Noise Abatement Departure Procedure (NADP) for the optimization of the engine thrust and flight path to reduce noise and the fuel-efficient engine. The other giant airplane, A380, is also known to have a quiet cabin.

Allowing the wings to flex improves aerodynamic stability. The aircraft is more streamlined and experiences less drag. It helps provide a smoother ride for passengers and minimize turbulence. The 787 fly-by-wire technology also helps here to automatically raise or lower the wing trailing edge during the cruise.

On board the Boeing 787-9, you can expect a new, comfortable travel experience and many innovations that will make your flight even more relaxing in the future. Look forward to the Dreamliner effect on your next trip.

The issue pertains to wrinkling in the forward pressure bulkhead in the jets' noses, the person said, asking not to be identified because the details are private. The defect isn't considered a threat to flight safety, the person said.

MORE DETAILS

A report in 2021 revealed that Boeing Dreamliners are among the world's safest planes in terms of accidents. There have been no fatalities or events involving extensive damage during more than a decade of flights using the model.

MORE DETAILS

Answer: Yes, the 787 is a safe airplane. The design has been tested and certified.

MORE DETAILS

While the 787 Dreamliners have not been grounded, the FAA had ordered a halt to deliveries of the widebody jet between May of 2021 and July of 2022 as it looked into questions about quality control during its assembly process.

MORE DETAILS

The typical lifespan of airliners The composite-driven Boeing 787 Dreamliner is designed for 44,000 flight cycles. These jets can theoretically last several decades with an average of two flight cycles a day. Unlike commercial airliners, fighter jets are unique due to their mission requirements.

This advanced fly-by-wire system also is the key to Smoother Ride Technology – unique to the 787 family -- which senses turbulence and adjusts control surfaces automatically to dampen its effects before it reaches the passengers.
