1. A high lift system for an aircraft, comprising:

  • a main wing,a flap that is arranged on the main wing of the aircraft and is adjustable relative to the main wing between a retracted position and several extended positions by means of flap actuating elements and a drive device,at least one spoiler movably coupled to the main wing,a motive coupling provided between the at least one spoiler and the flap such that the spoiler moves in complementary fashion as the flap moves, anda carrier part arranged on the main wing, to which the flap actuating elements are coupled and relative to which the flap actuating elements are movable in order to adjust the flap wherein,the carrier part is arranged on the main wing with the aid of a bearing device that features an adjusting device comprising a first adjusting device and a second adjusting device which have a distance from each other along a flow direction, and by means of which an orientation of the carrier part is adjustable relative to an orientation of the main wing,at least one of the adjusting devices includes;

    a distance adjusting device, by means of which a distance of an upper side of the carrier part on the distance adjusting device from a wing chord of the main wing is adjustable and which distance adjusting device comprises;

    a screw connection with a receptacle device on a side of the carrier part,a receptacle device on a side of the main wing,a connecting element for adjustably connecting the receptacle devices,a spacer located between the upper side of the carrier part and the main wing, andwherein the motive coupling is configured to couple the adjustment of the flap to an adjustment of the spoiler in such a manner that the spoiler assumes a spoiler droop angle, at which a predetermined gap dimension between the spoiler and the flap exists, so that when the orientation of the carrier part relative to the orientation of the main wing is adjusted the motive coupling effects a corresponding change of the spoiler droop angle in the extended positions of the flap to maintain essentially the same gap dimension between the spoiler and the flap.
