Winglets improve the aerodynamic efficiency of wings, but they also affect the wing's aerodynamic loading - and that matters. The changes can shorten the life limit of wings.

Their new active winglet is specifically designed so that it can be added to any aircraft without further modification to the wing's internal structure.
