787飞机的介绍，很简单。

B787 GENERAL
The Boeing 787 Dream liner is a twin-engine airplane for commercial transportation of passengers and cargo. The first Dream liner to enter into service is the 787-8. The 787-8 Dream liner carries 210 - 250 passengers on routes of 7,650 to 8,200 nautical miles
(14,200 to 15,200 kilometers).
The 787 flies at a speed of mach0.85 (approximately the same as
the 777 and 747).
Materials used on 787:
- Composites - 50%
- Aluminum - 20%
- Titanium - 15%
- Steel - 10%
- Other - 5%
The 787 is 20% more fuel efficient and produces 20% fewer emissions than similarly sized airplanes.
The new electric architecture of the 787 uses up to 35% less power from the engines than traditional pneumatic systems on today's airplanes. Efficient design features of the 787 are:
- Majority of airplane structure made from light weight carbon fiber reinforced plastic
(CFRP)
- Lower cabin altitude pressurization (6000ft) due to CFRP strength
- Larger flight deck and passenger windows
- Interior and exterior light emitting diode (LED) and high intensity discharge (HID) lights
- Flight deck with liquid crystal display (LCD) primary display system (PDS)
- Crew information system (CIS) with wireless data transmission between the terminal and the airplane
- Common core system (CCS) with high speed fiber optic common data network (CDN)
- Fly-by-wire flight control electronics (FCE)
- Three separate 5000 psi hydraulic systems
- Electric airplane architecture (no engine offbleed of pneumatics except engine anti-ice)
- Electrical control and operation of brake system
- Electrically heated wing leading edge antiice system
- Pneumatic source for air conditioningsystem is from electric motor cabin air
compressors (CAC).
Airplane Taxi
There should be a person in the captain and the first officer seats during taxi.When you taxi the airplane:
- Make sure brake power is available
- Make sure steering power is available
