The Boeing 777 currently is available in five models: 777-200, 777-200ER (extended range), 777-200LR (longer-range), 777-300 and the 777-300ER (extended range). The 777 program was launched in October 1990 with an order from United Airlines. In June 1995, United flew its first 777 in revenue service.
The Triple Seven is Boeing’s first application of fly-by-wire, an advanced technology glass flight deck with five liquid crystal displays, comparatively large scale use of composites (10% by weight), and advanced and extremely powerful engines. The 777 was also offered with optional folding wings where the outer 6 m of each would fold upwards for operations at space restricted airports.
Boeing 777-200 Freighter:
Due to enter service in fourth quarter 2008, the new Boeing 777 Freighter is based on the technologically advanced 777-200LR (Longer Range), the world’s longest-range commercial airplane. The 777 Freighter will fly farther than any other freighter and will provide more capacity than any twin-engine cargo airplane.
The new freighter brings Boeing’s 777 family to six models. Boeing selected the 777-200LR platform for the new Freighter because it offers the preferred mix of range and payload capabilities for cargo operators. The first 777-200LR will enter passenger service in 2006.
The 777 Freighter will have a revenue payload capability of 101 metric tons and will accommodate 27 standard pallets (244 x 318 cm) on its main deck and 10 in its lower cargo hold. It can fly 9,630 km with a full payload and market-preferred cargo load density. Delivering the lowest trip cost of any large freighter, the 777 Freighter will meet QC2 noise standards for maximum accessibility to noise-sensitive airports.
