An arrangement of lifting surfaces comprising a primary lifting surface (1) having a flexural axis (4) extending in the spanwise direction of the lifting surface, a root, and a tip (3). A first tip device is attached to the tip and has a first lifting surface (7). A second tip device is attached to the tip and has a second lifting surface (9). A control system is coupled to the first and second tip devices for moving the first and second lifting surfaces relative to the tip and/or for actively controlling circulation of the first and second lifting surfaces. The control system is operable to change a value of torque effective at the primary lifting surface about the flexural axis. Also, a method of controlling an arrangement of lifting surfaces.
