Like winglets, they increase the effective wing aspect ratio and diminish wingtip vortices, decreasing lift-induced drag. In testing by Boeing and NASA, they reduce drag by as much as 5.5%, compared to 3.5% to 4.5% for conventional winglets. [1] While an increase in span would be more effective than a same-length winglet, its bending moment is ...

The winglets improve fuel efficiency by five percent and increase range by 200 nautical miles (370 km; 230 mi) through the reduction of lift-induced drag. [87] [88] Continental Airlines was the first carrier to order winglets for the 757-200, and in February 2009 became the first operator of 757-300s with winglets. [89]
Boeing's new split-tip winglet on the 737 MAX. The 737 MAX uses a split-tip winglet, designed to reduce vortex drag, which improves fuel efficiency [132] by maximizing lift, while staying in the same ICAO aerodrome reference code letter C gates as current Boeing 737s. [133]
A winglet lift credit, achieved through additional winglet testing, that reduces the minimum landing-approach speeds. Takeoff performance improvements such as the use of sealed leading-edge slats on all takeoff flap positions, allowing the airplane to climb more rapidly on shorter runways.
The wing of the Boeing jet owned by former President Donald Trump struck a parked plane at a Florida airport Sunday morning, the FAA said Tuesday. ... was on his Boeing 757 when its winglet struck ...
The Federal Aviation Administration is giving Boeing 90 days to come up with a plan to fix quality problems and meet safety standards for building new planes. The agency said Wednesday that the ...
Washout near the tips can also be used to decrease lift-induced drag, since at a lower angle of incidence, the lift produced will be lower, and thus the component of that lift which acts against thrust is reduced, however, it has been theorised by Albion H. Bowers that certain washout characteristics in the tips, that lead to a bell-shaped span ...
