When affixed upward to the end of each wing, the 11-foot extensions, or winglets, will improve the efficiency of the 767s' wings by smoothing out airflow across the upper wing near the tip.
As a result, aerodynamic drag will be reduced, cutting down on the thrust needed to fly the same speed. The reduced thrust will lower fuel use and result in savings of between 700 and 800 ...
