Boeing777

The 777 transport is an aircraft jointly developed under the international cooperation of Japan and the U.S. The work share of Japan is approximately 20%, with MHI manufacturing the aft fuselage panel, tail fuselage, and entry doors. First flight was in 1994.
The outer diameter of the fuselage is as wide as 6.2m, the widest next to the 747, and can place a maximum of 500 seats (long fuselage type). As for the material used, a new type of aluminum alloy is used for the wing, and composite material is used for approximately 9% of the body, aiming to contribute to the improved weight reduction, duration increase, and fatigue strengthening. The most advanced system is introduced in the avionics to improve reliability, reduce weight, and save energy.
Being an ultra-large twin engine, a turbo engine equipped with high bypass ratio is installed.
