Why do large aircraft have vertical tips on the ends of there main wings?

Wingtip devices are installed in an attempt to improve the performance of the wing in some way. Because they vary a bit is shape and in the manner they are attached, the way they modify the performance of the wing varies. The vertical wingtip devices, or winglets, generally act to reduce the vortex at the wing tip and decrease drag. The general answer to the question is that they have the wingtip devices to improve the aerodynamic performance of the wing.
The vertical tip of the wing is called a 'winglet', and it is there to reduce the turbulence that is called a vortex, which is a spinning form of turbulence. These vortices can be clearly seen in videos of the space shuttle landing, when the camera angle is right. These vortexes cause drag, which slows the aircraft down, and reduces fuel efficiency.

What do you mean by blended wings in aircraft?
A BWB (Blended wing body) aircraft is where the fuselage and the wings blend seamlessly into each other, and you cant really tell where the fuse. ends and the wing starts. A brilliant example is the B-2.
What is the controlling surface that regulates an aircraft roll?
At the outer ends of the wings are 'ailerons'. These are like flaps, but when one goes up, the other goes down, thus the aircraft rolls.
Why are the ends of some airplane wings pointed up?
They are called winglets. They can help reduce drag on aircraft performance resulting in performance improvements of typically 5%.
How to you get wings in your hair?
you straighten it and then at the ends take hair gel and kind of make the ends go up and then its wings
When will you grow wings?
When the world ends!
What spring pushes the object attached to its ends?
Vertical
What is Wing tip to wing tip?
Two or more planes flying in formation with the ends of their wings almost touching.ANS 2 - Wing tip to wing tip is also a way of expressing the wing span of an aircraft
What is a dual pitched roof?
a gable roof is double pitched with vertical ends
Does Lugia the Pokemon have wings or arms?
Lugia has wings (he uses them to fly) but the ends look like fingers so it's confusing.
Why is there a US flag on tail ends of air force aircrafts?
to show that they are American aircraft
What does EBW stand for in retail?
Ends, Bulks and Wings related to merchandising associated with end caps.
Why is there a US flag on tail ends of some air force aircrafts and not other air force aircraft?
It just signifies the aircraft is able to carry U.S. Mail. Mostly carrier aircraft that are use to deliver mail to deployed locations.
