Winglets on Icelandair B752's
Icelandair have quite large winglets on their Boeing B752's.
This reduces induced drag by about 2-4 % ?
Usually the wings have to be strengthened when winglets are added.
I don't see many other B757's with winglets.
Is the benefit really worth the effort ?

Winglets add profiledrag and reduce induceddrag. There is allso the weight penalty. On short flights it is not worth the effort on long ones yes. The normally quoted figure is a 4 hour flight.

Indeed, Finnair have modified their fleet - they fly over my house most days!!
I may be wrong, but I think I read that Finnair 757s operate the longest average sector length of the type.
It's 6+ hours to the Canaries from here (Helsinki).
