A wing for an aircraft having a fixed wing, a foldable wing tip portion rotatably attached to the fixed wing and an actuation unit for rotating the foldable wing tip portion relative to the fixed wing about a hinge axis is disclosed. The actuation unit includes a traction means for transmitting traction between the fixed wing and the foldable wing tip portion, a main wheel attached to the foldable wing tip portion and in contact with the traction means and a drive means for generating traction to be transmitted by the traction means. The actuation unit generates traction with the drive means in the traction means so that the foldable wing tip portion can be rotated relative to the fixed wing.

An actuator comprising first and second motors, first and second drive linkages, and a pivot mount configured to pivot about a pivot axis, the pivot mount connected to the first and second drive linkages at first and second mount connections offset first and second offset distances from the pivot axis, the motors and first and second drive linkages configured to provide first and second load paths between a drive housing and the pivot mount so that in a first operation state the pivot mount is in a force-balanced orientation about the pivot axis, and a proximity detector positioned to detect when the pivot mount rotates about the pivot axis above a threshold out of the force-balanced orientation, wherein a force imbalance on the pivot mount caused by a fault in one of the first or second drive linkages above a threshold is detected by the proximity detector.

A wing for an aircraft is disclosed including a main wing and a trailing edge high lift assembly movably arranged at a trailing edge of the main wing, the trailing edge high lift assembly having a flap and a connection assembly movably mounting the flap to the main wing, such that the flap is movable between a retracted position and at least one extended position. The connection assembly includes an actuator unit for moving the flap between the retracted position and the at least one extended position. The flap includes a leading edge part and a trailing edge part mounted to the leading edge part in a manner pivotable about a pivot axis.
