Known wing systems are directed at optimizing aircraft cruising performance. The present base flap system may be used for setting a span load distribution of an aircraft wing during takeoff and landing. The base flap system comprises at least one inner flap element and one outer flap element. The inner and outer flap elements are arranged on a trailing edge of the wing, along the direction of the wing span. The inner and outer flap elements are not mechanically coupled with each other and are controlled independently of each other for the purpose of setting the span load distribution. The system also comprises a flap control that controls the angle of the outboard flap element, independent of the inboard flap element, for optimizing a lift to drag ratio during aircraft takeoff and landing. |
