LANDING GEARS 777 series features the largest landing gear and the

biggest tires ever used in a commercial jetliner.

The six-wheel bogies are designed to spread the load of the aircraft over a wide area without requiring an additional centerline gear. This helps reduce weight and simplifies the aircraft's braking and hydraulic

systems. Each tire of a 777-300ER six-wheel main landing gear

can carry a load of 26,980 kg, which is heavier than other wide-bodies such as the 747-400

FOLDING WINGTIPS

Large folding wingtips, 6.40 m long, were offered when the 777 was first launched, to appeal to airlines who might use gates made to

accommodate smaller aircraft, but no airline purchased this option.  Folding wingtips reemerged as a design feature at the

announcement of the upgraded 777X in 2013. Smaller folding wingtips of 3.35 m in length will allow 777X models

to use the same airport gates and taxiways as earlier 777s. These smaller folding wingtips are less complex than those proposed for

earlier 777s, and internally only affect the wiring needed for wingtip lights.
