Does the 737-800 have winglets?
These new technology winglets are now available on 737-800s as well as on the Boeing Business Jet (737-700 and 737-800). There are two types of winglet available, Boeing’s own built into the wing at the time of manufacture and the APB winglet as a retrofit.

Does the 737 have winglets?
Aviation Partners says it has fitted 10,000 aircraft with their winglets — in the 737, 757 and 767 families, as well as business jets — which they estimate has saved a total of 13 billion gallons of fuel.
What are the winglets on the Boeing for?
More than 2,850 Boeing airplanes have been equipped with blended winglets. The carbon-fiber composite winglets allow an airplane to save on fuel and thereby reduce emissions. The fuel burn improvement with blended winglets at the airplane’s design range is 4 to 5 percent.
How much do winglets cost?
Winglets cost anywhere from $500,000 for a 737 to more than $2 million for bigger planes. But the payoff can be rapid. Southwest Airlines estimates that it saves 54 million gallons of fuel every year thanks to equipping 93 percent of its fleet of 737s with winglets.
What is the difference between winglet and sharklet?
There is no real difference between the two types of winglets apart from cosmetics. They are so close in design (that Airbus was proven to be infringing on a patent) that no version is better than another. However, winglets and sharklets are both solutions to inefficient wing design from earlier aircraft.
Which winglet is the best?
The shark fin-alike winglet was overall the most efficient design, followed shortly by the famous blended design found in many mid-sized airliners. The worst performing designs were surprisingly the fenced and spiroid designs, which had efficiencies on par with the wing without winglet.
What is a 737 winglet?
Boeing is introducing the very latest in advanced winglet technology, the 737 MAX AT Winglet. In addition to the inward, upward and slightly forward lift components of the upper aerofoil, the new lower aerofoil generates a vertical lift component that is vectored away from the fuselage, and also slightly forward.
How much does a 737 winglet cost?
Why are winglets so expensive?
The popularity of the wings makes them more expensive. This goes back to a classic supply and demand situation. The supply of wings has a hard time keeping up with the demand. As wings get more and more popular, there are other places that are starting to offer wings.
Why do some planes not have winglets?
If winglets are so great, why don’t all airplanes have them? Because winglets are a tradeoff: In the highly visible case of the 777, an airplane with exceptionally long range, the wings grew so long that folding wingtips were offered to get into tight airport gates.
What are the 737 MAX winglets called?
split-scimitar winglets
The 737 MAX is fitted with Boeing’s trademark split winglets, also called split-scimitar winglets. Dubbed the 737 MAX AT Winglet, they are a unique design incorporating features from blended, split-scimitar and raked winglets.
