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?

  • $\begingroup$ Are you asking about that bent bit at the end? (Winglets - see this question for a picture) $\endgroup$ – Dan Pichelman Oct 26 '17 at 17:43

    $\begingroup$ Are you asking about winglets or flexible wings? $\endgroup$ – Farhan Oct 26 '17 at 17:44

    $\begingroup$ @Farhan I think he's referring to the dihedral angle $\endgroup$ – TomMcW Oct 26 '17 at 17:45

    $\begingroup$ @TomMcW: Or it could be the upward flexing of the wings while in flight? Which has an answer here: aviation.stackexchange.com/questions/838/… $\endgroup$ – jamesqf Oct 26 '17 at 19:10

All wings do flex, but in some modern airliners, the wings are built, fully or in part, with modern composites, that may deform within a larger elastic interval than metals...
