First Boeing 777 -- a 777-300ER -- Receives Raked Wing Tips

Mechanics in the Boeing final assembly factory in Everett, Wash., this week installed raked wing tips onto the newest 777, the 777-300ER (extended range) airplane. The 6.5-foot (1.98-meter) raked wing tips are highly tapered wing extensions used to improve an airplane's performance. The raked wing tips reduce takeoff field length and increase fuel efficiency and climb performance. Each wing tip weighs 105 pounds (48 kilograms) and are installed using 12 bolts. The raked wing tips are manufactured by Korean Air Lines' Aerospace Division.
