Boeing 777
Each engine on the 777 has a diameter approximately the size of a 737’s fuselage
All of the engines on the Titanic delivered around 46,000 horsepower combined. Just one of the GE units on the 777 puts out over 111,000 horsepower
During certification testing in 2002, the GE90-115B engine (777-300) set a world-record 127,900 lbs. of thrust. The GE90-115B ran for approximately 60 hours at triple red-line conditions (max fan speed, core speed and exhaust gas temperature) to evaluate the engine at its operational limits and demonstrate its capability beyond the most extreme operating conditions
There are 3 million parts in a Boeing 777 provided by more than 900 suppliers
The 777 was named winner of the prestigious Robert J. Collier Trophy by the U.S. National Aeronautic Association, which honored the Boeing 777 as the top aeronautical achievement of 1995
The 777 can cruise 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 in a commercial jetliner. With six wheels on each main landing gear, and two wheels on the nose gear, it has an unmistakable footprint
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 kilometers or 12,455 miles), and it set the record for “Speed Around the World, Eastbound,” traveling at an average speed of 553 mph (889 kilometers per hour)
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 the Pratt & Whitney-powered Boeing 777, 180-minute ETOPS
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. If you collected the equivalent of all this data on 3.5-inch diskettes the stack of these diskettes would be 13,368 feet (4,074.5 meters), which is taller than Mt. Fuji in Japan, which stands 12,338 feet (3760.6 meters)
Today’s Boeing 777 operators enjoy a 99 percent dispatch reliability rate
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 in a 777-200
A lightly loaded Boeing 777 can accelerate from zero to 60 mph in less than six seconds
For engine testing, birds weighing up to 8 lbs. were launched into the engines & a rainstorm with 80 inches of rain per hour was created
As of December 2016, 60 customers had placed orders for 1,902 aircraft of all variants, with 1,460 delivered. The most common and successful variant is the 777-300ER with 702 delivered and 809 orders; Emirates operates the largest 777 fleet, with 157 passenger and freighter aircraft as of July 2016
The Boeing 777 is manufactured in Everett, Washington – the plant is so large that it requires its own fire department, security force, fully equipped medical clinic, electrical substations and water-treatment plant. The site’s main assembly building, which the Guinness Book of World Records acknowledges as the largest building in the world by volume, its footprint covers 98.3 acres
The 777 was aimed to replace DC-10s and L-1011s
United was the launch customer for the 777 project
Cathay Pacific was the launch customer for the 777-300 project
During takeoff, the 777’s engines push 2 million cubic feet of air per minute. That’s enough air to keep a human breathing for 44 days
