Boeing
is offering airlines more range on its longer-range 777 passenger airplanes, and enhanced performance overall, thanks to engine efficiency
improvements and design changes that reduce wind drag and the airplane's
weight.
The enhancements for the Boeing 777-300ER (Extended Range) will become
available during 2005's fourth quarter. They'll be offered on new airplanes and for
retrofit on airplanes already in service.
With the improvements, the airplane's maximum range would increase by 175
nautical miles to 7 ,880 nautical miles (14,594 kilometers). Its center of gravity limits
will also rise, providing greater cargo loading capability when the airplane
operates at its highest gross weight.
"These enhancements increase the 777-300ER's value and give our customers
the increased range and cargo loading flexibility they want," said Lars Andersen,
Longer-Range 777 program manager. "The efficiency, economics, and capabilities
of this airplane are unsurpassed."
Specifically, the enhancements include improved fuel efficiency from the General
Electric GE90-115B engines, drag reducing aerodynamic improvements such as wing vortex generator
changes and ram air system modifications, and interior changes that reduce
weight.
As part of the package, airlines can choose an innovative option that stores food
and beverage carts directly above the passenger cabin rather than on the main
deck. That would provide airlines with more main-deck space for revenue-generating seats.
Boeing is applying several of the enhancements to the 777-200LR (Longer Range)
airplane currently under development. The airplane will have a range capability of 9,420 nautical miles (17,446
kilometers). The first 777-200LR will be delivered during the first quarter of 2006. |
