A swinging drive link (10) is pivotally connected at its lower end (18) to a forward support (16) for a flap (20). The flap rear support is provided by a pivotal connection (24) between a rear support point and the lower end of a swing link (22). The upper end of the swing link (22) is pivotally connected (31) to the upper end of a support link (26) and the rear end of a slave link (30). The lower end of the support link (26) is attached (27) to a beam structure (28) projecting rearwardly from the main wing section (13, 29). The forward end of the slave link (30) is pivotally attached (40) to an intermediate portion of the drive link (10). Rearward rotation of drive link (10) causes the flap (20) to translate rearwardly with a small amount of downward rotation until the flap (20) is essentially completely extended. Then, further extension of the mechanism rotates the flap (20) a substantial amount downwardly. In a double slot embodiment (Fig. 7-9), similar linkage is provided between a forward main flap (66) and an aft flap (64).
