1. A wing tip device for fixing to an outboard end of a wing, the wing defining a wing plane, the wing tip device comprising:
an upper wing-like element projecting upwardly with respect to a wing plane and having a trailing edge; and
a substantially planar lower wing-like element fixed with respect to the upper wing-like element and having a root chord and a trailing edge, the lower wing-like element root chord intersecting with the upper wing-like element, and the lower wing-like element projecting downwardly from the intersection,
wherein the trailing edge of the lower wing-like element is adjacent the trailing edge of the upper wing-like element at the intersection,
wherein a length of the upper wing-like element, measured from a tip of the upper wing-like element to the intersection, is substantially 1.8 times longer than a length of the lower wing-like element, measured from a tip of the lower wing-like element to the intersection, and
wherein an included angle between the upper and lower wing-like elements is approximately 90 degrees.
