 Boeing 777-300

Compared with the baseline 777-200 the 777-300 features a 10,13 m stretch, comprising plugs fore and aft of the wings. The longer fuselage allows seating for up to 550 passengers in a single class high density configuration. Boeing publicly announced it was developing the 777-300 at the Paris Airshow in mid June 1995. The 777-300 rolled out on September 8 1997, followed by first flight on October 16 that year.

The 777-300ER is the first of two new Longer-Range 777 models. The 777-300ER and the 777-200LR (Longer Range) were launched in February 2000 at the request of airline customers seeking airplanes with additional flexibility to serve the non-stop routes that passengers demand.

The twin-engine 777-300ER carries 365 passengers up to 14.270 kilometers, and is capable of serving such routes as Paris-Los Angeles and Paris-Tokyo.

During the 777-300ER’s 1,500-hour flight test program, the airplane exceeded its original design performance targets. As a result, the new jetliner provides increased payload and range capability over those promised to customers at the time of the airplane sale.

The 777-300ER has updated avionic, electrical, flight and environmental control systems. The airplane’s raked wingtips offer fuel efficiency improvements and its semi-levered landing gear permits takeoffs on shorter runways.

The 777-300ER also features the award-winning Boeing Signature Interior, known for its ambient lighting and easily accessible drop-down luggage bins.

General Electric Aircraft Engines manufactures the engines for both Longer-Range 777 models. The GE90-115B turbofan is the world’s largest and most powerful commercial jet engine, producing 115,000 pounds of thrust, currently a Guinness World Record.

On Friday, December 3, 2004 was the rollout of the 500th Boeing 777 commercial airplane. The Boeing 777 the fastest-selling twin-aisle airplane ever, will reach 500 airplanes delivered faster than any other twin-aisle airplane in commercial history. The 500th 777 is scheduled for delivery to International Lease Finance Corp. and operator Air France later this month. Thirty-eight customers have ordered 647 Boeing 777.
