The Boeing 787 Dreamliner is a long-range, wide-body, twin-engine jet airplane that DSC_0279can seat between 210 and 290 people, depending on the particular airline’s configuration.  It is notable for being the world’s first aircraft to use composite materials for most of its construction, which makes it lighter and far more resistant to corrosion than earlier jets.

In size and capacity, the Dreamliner is similar to the Boeing 767 but it consumes 20% less fuel.  From a visual standpoint, the aircraft’s distinguishing features include a four-panel windshield and noise-reducing chevrons on its engine nacelles.  The Boeing 787 Dreamliner was introduced as the 7E7 in 2003, after Boeing cancelled its Sonic Cruiser project.  It was renamed the 787 in 2005 and rolled out in 2007.

Launch customer All Nippon Airways flew the Dreamliner on its first regular route, Tokyo-Okayama,in November 2011.

1.) What is different about the Dreamliner?

The first things most passengers notice are the very large windows (they are, in fact, 30% larger than those on most other aircraft), which have an electrochromic dimming feature instead of shades. DSC_1151 The windows, located at a higher eye level, make the cabin seem much more airy and give passengers a better view of the horizon.  The design allows passengers not seated at a window to see outside as well. The windows may be dimmed by means of a button at each window and all of the windows can be dimmed remotely by the cabin crew to darken the aircraft for sleep.

The aircraft itself is made using composite materials.  This has several implications beyond the fuel savings derived from the reduced weight, including cabin pressurization set to 1,800 m (6,000 ft) altitude instead of 2,400 m (8,000 ft), which is the norm on older aircraft. As a result, passengers should experience fewer headaches and arrive at their destinations less fatigued since the lower altitude setting allows the blood to absorb more oxygen.

For improved air quality relative humidity is maintained at 15% instead of 4%, also possible due to the use of composites, which, unlike metals, aren’t subject to corrosion.  Cabin air is provided by compressors instead of using engine-bleed air, a far more efficient process that uses less energy. The use of HEPA filters to remove airborne particles, a gaseous filtration system that removes odors, irritants, and gaseous contaminants that can affect throats, eyes, and noses, and a system that removes ozone from outside air also contribute to passenger comfort.

Gust control is another major innovation introduced in the Dreamliner.  The “smoother ride” technology is designed to sense – and counter – turbulence while in flight.
