Why 787 is better?

Why 787 is better? This high aspect ratio wing design combined with efficiency enhancing raked wing tips allow the 787 to be one of the fastest commercial aircraft (Mach 0.85 cruise speed) while consuming less fuel than today's comparably sized aircraft.

Why are 787 wings so flexible?

The wings of the 787 are flexible due to the use of composite materials such as CFRP or carbon fiber-reinforced polymer (CFRP). Boeing claims that this composite material makes up approximately 50% of the wings on the Dreamliner.

Why is the 787 so comfortable?

Smoother Ride Technology: Sensors on the 787 sense and dampen turbulence for a more comfortable ride and less motion sickness. Large overhead bins: There's space for your carry-on near your seat. Better seating options: The 787 offers the latest in seat comfort and technology.

Do pilots like the 787?

In addition, the 787 is much quieter than other aircraft, so pilots can enjoy a quieter cockpit. The 787 also offers improved cabin comfort for airline pilots. The Dreamliner's cabin is pressurized to a higher altitude than conventional aircraft, which makes it easier to breathe and reduces fatigue during long flights.

Why is Boeing 787 so quiet?

To combat the sound of jet-blast from the rear of the engine, Boeing, General Electric, and NASA developed serrated edges called chevrons for the back of the nacelle and the engine exhaust nozzle. The chevrons reduce jet blast noise by controlling the way the air mixes after passing through and around the engine.

Is the 787 better than the 747?

The 747-400 uses 10 tons of fuel per hour. The 787 uses five tons per hour. With such a massive difference, it's clear why the sky is full of 787s at the moment and not 747s. However, with 40 years of technological improvement between the two models, it's not surprising that 787 performs so much better.

Is 787 better than A380?

We can see that the smaller variants of the 787 have a better range than the larger 787-10. In fact, the mid-sized 787-9 even outranks the A380. However, in terms of the comparison to the larger 787-10, the A380 appears, on paper, to be the more flexible aircraft on account of its longer range.

Does 787 have bleed air?

The 787 Dreamliner uses a “bleedless” pressurisation system, meaning that it does not use any bleed air from the aircraft's engines.

Are 787 planes safe?

Incredibly safe. The 787–8, —9 & —10 are as safe as it's going to get in aviation. The issue with the 787 spacing issues — where gaps are larger than 0.005 inches — is a fatigue and cycles related issue. In normal manufacturing, their are manufacturing tolerances to account for slight differences in part builds.

Is the 787 a smooth ride?

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.

Why Dreamliner is the best?

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.

Why 787 is better than A350?

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.

Why is the 787 so loud?

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.

Why 787 is called a Dreamliner?

In July 2003, a public naming competition was held for the 7E7, for which out of 500,000 votes cast online the winning title was Dreamliner. Other names included eLiner, Global Cruiser, and Stratoclimber. All Nippon Airways launched the 787 program with an order for 50 aircraft in 2004.

Is flying on a 787 better?

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.

Is the 787 a success or failure?

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.

Which 787 is most popular?

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.

Is 777 or 787 better to fly?

To start the Boeing 777 vs 787 comparison, we must say that the 787 is a more fuel efficient aircraft than the 777 thanks to its use of composite wings and more aerodynamically efficient design.

What is the 787 controversy?

The FAA said the leaks could damage critical equipment and lead to a “loss of continued safe flight and landing.” The agency said one airline found wet carpet in the cockpit of a plane and, when it inspected its entire fleet of 787s, found “multiple” planes with leaking faucets.

Which is safer Boeing 777 or 787?

The Boeing 787 has similar safety features to the 777, but also features improvements such as a wider and longer aisle space for passengers and smoother engine takeoff capability which can reduce air turbulence and improve safety during takeoffs.
