Why doesnt the B777 use winglets?
I have done many searches on this topic, but all i can seem to find is 'the 777 uses a computer designed wing and bla bla bla...' Im not sure if this cuts the mustard, so a few other ideas i have come up with
-Supercritical wing (although i am not sure if there are other transport cat a/c with this)
-High aspect ratio (as above)
-Raked wingtips
Can anyone else add to the list? and perhaps explain this question.
