The wing tips are very different on these airplanes. The wingtip on a Boeing 787 is a sharp triangle, while the wingtip on a Boeing 737-300 is flat. British Airways Boeing 787-8 G-ZBJC wingtip | by ...

What is the reason for the drag due to wingtip vortices? This question is about (general) performance, but doesn't answer the drag aspect.

Winglets have been discussed fairly regularly, but not much can be found on the topic of endplates. What are endplates, how do they work, and how do they relate to winglets?

Lately I've seen a lot of aircraft that have the wingtips curved up. What is the reason for this?

Why are the tips of wings on new aircraft folded up? Is it safety or efficiency that is the concern? I have done multiple searches and all I ever seem to get are wingtip shoes!

I'm seeing some Beechcraft Barons with winglets. Do these improve performance and, if so, by how much?

I take regular visits to the Boeing website, and when I look at some pictures, the wings tend to edge/point up. Why is this?

I am familiar with the basic aerodynamics of wingtip vortex generation and I know that winglets reduce drag by reducing wingtip vortex generation. I have never seen any illustration of exactly how ...

I've flown on a couple of 737's recently and noticed that the wings are quite beautiful and have a distinctive upward sweep at the wingtip, almost like a vertical stabilizer. What advantages and what ...

I know that the swept wing decreases lift and the winglet increases lift. Is it better to have a winglet or a swept wing.

I know that the winglets on planes like the Boeing B737 and Embraer E-190 reduce fuel consumption, but do they do more than that, or are they just for the stated purpose?
