The Boeing 777-300
is a high-capacity stretched version of the newest wide-body twinjet
from Boeing Commercial Airplane Group. This newest member of the 777
family of jetliners is "market driven" to meet airline
demand for a jetliner sized to replace older wide-body airplanes,
including early versions of the 747.
complements the 777-200 models by providing greater capacity and lower
costs per seat within the 777 family.
777-300 is stretched 33 feet (10 m) from the initial 777-200 model, to
a total of 242 feet 4 inches (73.9 m). As a result, capacity is
increased to 368 to 386 passengers in a typical three-class
configuration or 451 to 479 passengers in a typical two-class
configuration. In an all-economy layout, the 777-300 can accommodate
as many as 550 passengers.
In terms of range
capability, the 777-300 can serve routes up to 5,960 nautical miles
(11,030 km). A typical route is Tokyo to Singapore, Honolulu to Seoul
or San Francisco to Tokyo.
The 777-300 has
nearly the same passenger capacity and range capability as the
747-100/-200 models, but burns one-third less fuel and has 40 percent
lower maintenance costs. The overall result for airlines is cash
operating costs one-third below early model 747s.
takeoff weight is 580,000 pounds (263,085 kg); highest maximum takeoff
weight being offered is 660,000 pounds (299,375 kg). Maximum fuel
capacity is 45,220 gallons (171,155 L).
The 777-300 can
accommodate eight 96- by 125-inch (2.44- by 3.17-m) pallets, 20 LD-3
containers and 600 cubic feet (17 m3) of bulk cargo in its
lower holds, for a total available cargo volume of 7,080 cubic feet
Boeing board of directors authorized production of the 777-300 on June
26, 1995. Boeing had been studying the market feasibility of
"stretching" the popular 777-200 for some time, involving
more than a dozen airlines in "working groups" to establish
customer requirements and firm up aspects of the design for the
proposed airplane. In this way, the market-driven approach that led to
the 777-200's launch in 1990 continued to shape the 777 family with
the stretched 777-300.
authorization, or "go-ahead," for the program followed
announcements at the 1995 Paris Air Show that four airlines (All
Nippon Airways, Cathay Pacific Airways, Korean Airlines and Thai
Airways International) intended to order 31 of the long-range twinjets
valued at approximately $3.1 billion, depending on configurations,
special features and options selected -- the first Boeing program
launched entirely with international orders.
of the first 777-300 in May 1998 to Cathay Pacific Airways of Hong
Kong, the 777 family of aircraft provides the unparalleled level of
flexibility, economy and capability originally envisioned with the
launch of the program in 1990.
