Why 787

Designers did away with the use of the hydraulic system and all its associated architecture and instead used electricity to power the brakes. When the pilots press on the brake pedals, an electrical signal is sent directly to the brake unit on the wheel. Here, electrically powered actuators are used to press the carbon brake disc against the wheel, slowing it down. By changing to electric brakes, a saves pounds 64 kilograms per aircraft and a saves pounds kilograms.

Smart features also allow engineers to monitor the brake performance more closely, giving a real-time measurement of wear on the carbon disks. The anti-icing system, too, is powered electrically. Other aircraft types use bleed air from the engines to pass hot air through the leading edge of the wing to stop ice from forming.

This hot air then vents out into the atmosphere through dedicated hot air exhaust holes. Like with the air conditioning system above, this requires power to be sapped from the engine resulting in a greater fuel burn. The uses a series of electrically heated blankets that are bonded to the inside of the leading edge structure.

The heating of these blankets is enough to melt any ice forming on the wing. This system is far more effective, using around half the power that a traditional bleed system would use.

In addition, because there are no bleed air exhaust holes, drag over the wing and generated noise are reduced, making the Dreamliner not only more fuel efficient but also quieter. The Dreamliner really has changed flying for passengers, pilots and airlines alike. Even though you may not have not noticed it, there are several small differences that all add up to making it one of the best aircraft to fly long-haul on.

The changes to the cabin environment mean that passengers arrive more refreshed and less fatigued from their journey, and the guest suppression system will help ease the worries of nervous flyers. In the flight deck, the HUD provides pilots with a fantastic new way to interact with the aircraft, increasing situational awareness and, as a result, safety. Featured photo by Ryan Patterson.

See why American Airlines is canceling hundreds of flights. Airbus CEO: Aviation has found a solution after a roller coaster year. Boeing BA on Tuesday disclosed a new issue with the Dreamliner widebody jet, which has been dogged with problems since August.

The company said some of the planes' fuselage was not joined together to meet precise standards and there are questions about the verification process to make sure they meet the standards. The locations where parts of the plane are joined must meet precise standards down to a small fraction of an inch.

There are questions about the inspection process used to check that work. The company said it has been working with the FAA on the problem and identified a way to fix the s that haven't yet been delivered to customers. Boeing said planes already in service do not need to be grounded.

The FAA agreed, saying it is aware of a manufacturing quality issue, and it "poses no immediate threat to flight safety. Read More. Boeing will fix the undelivered planes and inspect them before delivery.
