摘要

The first Boeing 777-200LR Worldliner, the world's longest range commercial airplane, completed its first flight in February and has begun a test program that will lead to its first delivery in January 2006. The 777-200LR, capable of connecting virtually any two cities in the world nonstop, is the fifth 777 model. It can carry 301 passengers up to 9420 nautical miles (17,445 kilometers). During the first flight, the airplane climbed to an altitude of 15,000 feet (4,572 meters) and an air speed of 270 knots, or about 310 miles (500 kilometers) per hour, customary on a first flight. Typically, the 777's cruise altitude is 35,000 feet (10,668 meters), and its cruise speed is Mach 0.84, about 484 miles (779 kilometers) per hour. It will carry 20 more passengers, offer 12 percent more revenue cargo volume, consume 25 percent less fuel per seat, and fly 600 nautical miles farther than the competition, the A340-500. GE Aircraft Engines makes the 777-200LR World-liner's engines.
