First Split Scimitar Winglet Equipped 738 Sighting

First sighting of a Split Scimitar Winglet equipped on a United Airlines 737-800 by Aviation Partners Inc. and The Boeing Company. ( More...

Nice photo bomb by Southwest.
Boeing seems to be adopting Airbus technology with the split winglet while Airbus is adopting Boeing technology with its new "sharklets". Could some aerodynamics guru explain why these subtle changes are adding more efficiency or is it just another marketing spiel where for example they say 2-3% reduction in takeoff but 2-3% increase in cruise flight thus negating each other

Maybe Airbus knows something that Boeing doesn't? Sharklets make sense - splits don't
As read in an article linked below, Boeing proposed the design on the MD-12. Never-the-less, efficiency is all the buzzword these days, and if it is indeed proven (which again the article states), then give the customers that option.

It's all about the better mouse-trap!

It doesn't matter if it makes sense or doesn't make sense. In this case, "sense" is what you think they look like, they are a little different, but like all things different, their performance speaks volumes and if they can save some fuel and reduce some drag, then they are here to stay. Get used to em! ha

Boeing said that the split winglet was more efficient than the old winglet. Airbus just went ahead and used Boeing's design and didn't look into the actual thing to much.
Nick, with all the engineers on-staff, plus contractors, you would think that any aircraft maker would have known about it long before someone adopted the technology.

And if I was a big buyer, with market influence, I sure as heck would be asking if not, why not? I think that would motivate builders more than anything else.

Has it been shown that this split winglet in fact does improve the performance characteristics of the 737 or is it a design exercise to look different. I think there may be a problem with damage in the case of any severe cross winds where there may be a wing strike on the runway. (look at the video of a Lufthansa A320 landing at Hamburg in a severe cross wind where its left wing had struck the runway.) There will be even less latitude for error in this case.

Boeing did not copy airbus!

Wonder how often those will get banged up by the ground crews.
What a wild winglet (scimitar)! It sort of looks like an NG version of the wing tips on the MD-11, in a way, anyway.

Is this in fact a performance enhancing device or a design exercise? There could be a significant amount of damage in the case of a severe Cross wind landing. (check out the you tube video of a Lufthansa A320 wing strike at Hamburg as it was attempting to land with severe cross winds.) The under wing device that Boeing is adopting is protruding much further down and leaving even less margin latitude.
