Boeing has reached a milestone delivery in its 777-300ER programme, delivering the 300th aircraft to first-time customer Biman Bangaldesh on 21 October.
The airframer as of 30 September had recorded 543 orders for the 777-300ER from 37 customers. Boeing stated 27 customers currently operate the aircraft and 10 additional operators plan to accept delivery of their first 777-300ERS through 2014.
Approximately 35 percent of the 777-300ER was changed from earlier 777 models. Each wing was extended by 1.98m (6.5 ft) by adding raked wingtips, which reduce takeoff field length, increase climb performance and reduce fuel burn.
The body, wing, empennage and nose gear of the aircraft were strengthened and new main landing gear, wheels, tires and brakes were installed. New semi-levered landing gear permits takeoffs on shorter runways.
The struts and nacelles were modified to accommodate the significantly higher-thrust engines. The aircraft are powered exclusively by the General Electric GE90-115BL engine, producing 512kn (115,300 pounds) of thrust.
