Boeing 777



Air India is now going to acquire 68 new aircrafts of which there is going to be a new fleet of boeing 777-200 LR and ER so I thought y not try and get sum information on it from the way i see it.Technological point of view.

The Boeing 777 is the first jetliner to be 100 percent digitally designed using three-dimensional computer graphics. Throughout the design process, the airplane was "pre-assembled" on the computer, eliminating the need for a costly, full-scale mock-up.

Boeing is offering its 777 customers new innovations that take advantage of the space in the overhead area of the airplane -- the area located between the top of the stow bins and the crown of the airplane. These innovations will allow operators to use the overhead space for crew rest stations and storage.

Thanks to a new wing, more efficient engine, and a lighter structure, the 777 makes efficient use of fuel. And this, in turn, means lower emissions per passenger seat. For every pound of fuel conserved, three fewer pounds of carbon dioxide are generated. The bottom line: Fuel efficiency isn't just good for economics, it's good for the environment.


Boeing 777 Facts
  • The first 777 entered service on June 7, 1995. Since then 777s have flown more than than two million flights.
  • There are 3 million parts in a 777 provided by more than 900 suppliers from 17 countries around the world.
  • In 2004, the 777 reached 500 deliveries -- faster than any other twin-aisle commercial airplane in history.
  • On Feb. 15, 1996, the 777 was named winner of the prestigious Robert J. Collier Trophy by the U.S. National Aeronautic Association. The award honored the Boeing 777 as the top aeronautical achievement of 1995.
  • The 777 is capable of cruising at altitudes up to 43,100 feet.
  • Boeing engineers designed and electronically pre-assembled the 777 using computers. New laboratory facilities enabled the various airplane systems to be tested together as a single integrated entity in simulated flight conditions, before the first jetliner took to the air.
  • The 777's landing gear is the largest ever incorporated into a commercial jetliner. With six wheels on each main landing gear, and two wheels on the nose gear, it has an unmistakable footprint.
  • The Industrial Designer's Society of America presented its Industrial Design Excellence award in 1992 for the 777 passenger cabin, and in 1993 for the 777's flight-deck design.
  • On Nov. 9-10, 2005, a Boeing 777-200LR Worldliner set a new world record for distance traveled non-stop by a commercial jetliner. The 777-200LR set a record distance of 11,664 nautical miles (21,601 km) on a route traveling eastbound from Hong Kong to London (Heathrow). The flight lasted 22 hours and 42 minutes. The achievements was recognized by the U.S. National Aeronautics Association, The Fédération Aéronautique Internationale and the Guinness Book of Records.
  • The Fédération Aéronautique Internationale recognized the Boeing 777 in April 1997 for achieving a speed and distance record for airplanes in its size and class. The 777 set the "Great Circle Distance Without Landing" record, traveling 10,823 nautical miles (20,044 km), and it set the record for "Speed Around the World, Eastbound," traveling at an average speed of 553 mph (889 km per hour).
  • The 777-200LR (Longer Range) -- the world's longest range commercial airplane -- was named in 2000 to Popular Science magazine's top 100 list.
  • The 777 is named in a song by Dire Straits' Mark Knopfler. The song is contained on the CD "Sailing to Philadelphia."
  • The 777 is the first airplane to have a rose named after it. The rose is deep purple-red with a citrus-like fragrance. It was developed by Olympia, Wash., Western Independent Nurseries.
  • On May 30, 1995, the 777 became the first airplane in aviation history to earn U.S. Federal Aviation Administration (FAA) approval to fly extended-range twin-engine operations (ETOPS) at entry into service. On that date, the FAA awarded 180-minute ETOPS to the Pratt & Whitney-powered Boeing 777.
  • The 777 underwent the most extensive flight-test program ever conducted on a commercial jetliner. The flight-test program included nine airplanes, which flew more than 7,000 hours and 4,900 flights.
  • The data shared and transferred on the network during the design phase of the 777 program totaled 1,847,930,000,000 bytes of production data.
  • Today's 777 operators enjoy a 99 percent dispatch reliability rate -- the highest amongst all twin-aisle airplanes in service today.
  • The flight-control system for the 777 airplane is different from those on other Boeing airplane designs. Rather than have the airplane rely on cables to move the ailerons, elevator, and rudder, Boeing designed the 777 with fly-by-wire technology. As a result, the 777 uses wires to carry electrical signals from the pilot control wheel, column, and pedals to a primary flight computer.
  • There is approximately 50,000 cubic feet of volume in a 777-300, and 40,000 cubic feet in a 777-200.
  • A lightly loaded 777 can accelerate from zero to 60 mph (96 km/h) in less than six seconds.
