An aircraft includes a wing and a leading-edge aerodynamic surface coupled to the wing. An actuator is disposed within the wing and coupled to the leading-edge aerodynamic surface via a linkage system. Two or more hinge systems are coupled to the leading-edge aerodynamic surface and configured to rotate about a fixed axis internal to the wing to move the leading-edge aerodynamic surface between a retracted position and a drooped position.

Wing assemblies comprise a slat, wing support structures, and a gap-adjustment assembly configured to permit selective adjustment of the slat relative to the wing support structures. The gap-adjustment assembly comprises a track member and an adjustment member. The track member is pivotally coupled relative to the wing support structures about a track-member axis, the slat is operatively translationally coupled to the track member, and the track member is configured to constrain translation of the slat between a stowed position and a deployed position. The adjustment member is pivotally coupled relative to the wing support structures about an adjustment-member axis and pivotally coupled to the track member about a linkage axis. The adjustment member is configured to permit selective adjustment of a direct distance between the adjustment-member axis and the linkage axis.
