A METHOD AND A CONTROL UNIT FOR CONTROLLING ACTUATION OF A FOLDABLE WING TIP SECTION OF A WING OF AN AIRCRAFT

The invention relates to a method for controlling actuation of a foldable wing tip section of a wing of an aircraft. It comprises receiving (53) at a control unit (19) of an aircraft (1) a command signal (37). The aircraft (1) comprises a wing arrangement (3) which includes a wing (9) comprising a base section (11) having a first end portion (11a) adapted to be secured to the fuselage (5) of an aircraft (1) and an opposite second end portion (11b), and a tip section (13) having a third end portion (13a) and an opposite fourth end portion (13b), wherein the third end portion (13a) is pivotablyconnected to the second end portion (11b) such that the tip section (13) is pivotable about a pivot axis (17) between a deployed position and a stowed position in which the spanwise length of the wing(9) is smaller than in the deployed position, and an actuating system (21) which is coupled to the control unit (19) and which is operable to selectively move, under the control of the control unit (19), the tip section (13)
