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 pivotably connected 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) between the deployed position and the stowed position. The command signal (37) is adapted to instruct the control unit (19) to control the actuating system (21) to move the tip section (13) from the deployed position into the stowed position or from the stowed position into the deployed position. The method further comprises receiving at the control unit (19) a first condition indicating signal (29a) indicative of whether or not the aircraft (1) is on the ground and determining by the control unit (19) based on the first condition indicating signal (29a) if a first condition is met that the aircraft (1) is on the ground, receiving at the control unit (19) a second condition indicating signal (29b) indicative of a current speed of the aircraft (1) and determining by the control unit (19) based on the second condition indicating signal (29b) if a second condition is met that the current speed of the aircraft (1) is below a predetermined maximum speed, and receiving at the control unit (19) a third condition indicating signal (29c) indicative of whether or not the aircraft (1) is at a gate (31) of an airport (33) and determining by the control unit (19) based on the third condition indicating signal (29c) if a third condition is met that the aircraft (1) is not at a gate (31) of an airport (33), and controlling the actuating system (21) to effect the movement of the tip section (13) instructed by the command signal (37) only if all of the first condition, the second condition and the third condition are met.
