Why is the 787 so fast?

Why is the 787 so fast? 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 do planes fly at 43000 feet?

Commercial planes fly between 35,000 and 43,000 feet. This is usually the most optimal flight to create lift. Aircraft are generally around 7 miles above the ground traveling at nearly the speed of sound. The higher a plane flies, the thinner air surrounding it becomes.

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.

Is Boeing 787 fast?

The 787 is a widebody passenger aircraft capable of flying long distances at a cruise speed of 0.85 Mach (652 mph/1,050 kph).

How old are 787 planes?

The Boeing 787 Dreamliner is a passenger aircraft made by Boeing. Its first flight took place on 15 December 2009. It was planned to be released earlier, but the first passenger flight of the airplane was in October 2011. Because of delays some airlines got their aircraft more than two years late.

What went wrong with the 787?

There were fuel and oil leaks, a cracked cockpit window and a computer glitch that erroneously indicated a brake problem. Then a 787 flown by Japan's All Nippon Airways made an emergency landing after pilots learned of battery problems and detected a burning smell.

Why did Boeing stop 787?

Starting in the fall of 2020, Boeing found previous quality defects at multiple joins inside 787 fuselages that stopped almost all deliveries of the jet through August 2022, racking up more than $6.3 billion in additional “abnormal costs.”

How far can the 787 fly?

The 787-8 Dreamliner can fly 242 passengers up to 7,350 nautical miles (13,620 km) in a typical two-class configuration. The 787-9, a stretch of the 787-8, can fly 290 passengers 7,635 nautical miles (14,140 km) in addition to more cargo, allowing airlines the ability to grow routes first opened by the 787-8.

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.

Can a 787 Dreamliner fly on one engine?

As with every Boeing airplane, the 787 includes many layers of redundancy for continued safe operation, and the electrical system is no exception. For example, Boeing has demonstrated that the 787 can fly for more than 330 minutes on only one engine and one of the six generators and land safely.

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.

Is the 787 still grounded?

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.

Why did Airbus skip to A380?

The first is that the A380 carries double the passengers than the A340 (650 vs 380 depending on the configuration) and thus Airbus wanted to signify this in the name. Even looking at the two aircraft you can see that the A380 is essentially a double-decker A340. The second theory is that it is because of China.

Why is the 787 being retired?

The longer the 787s remained on the ground, the more it would cost to get them to fly again, due to the maintenance work required. As a result, they were no longer airworthy.

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 plane is nicer 777 or 787?

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.

Why do airlines not like A380?

The arrival of the A380 in 2007 was poorly timed. The price of jet fuel had begun to creep up, and by 2007 was floating at around $4 a gallon. This made airlines shy away from the expensive to operate four engine jets of the 80s and 90s, and to look instead to fuel efficiency as a major deciding factor.

Can a pilot fly both 777 and 787?

Re: 777 and 787 common type rating Pilots can fly both, even on the same day. That's what the common type rating enables. If you required differences to go between them after the initial differences course, it would not be a common rating.

Do you feel turbulence on a Dreamliner?

The B787 has an active turbulence suppression system, and the passenger experiences that as less turbulence.
