A drive and guidance apparatus for a trailing-edge/landing flap,-arranged on an aircraft mainplane, the apparatus comprising a six-element guide chain having seven rotating joints and one or more shafts; a first coupling element mounted via a crank connected to the mainplane wherein the crank can rotate, the coupling is connected to the flap and to a second coupling element wherein the first coupling can rotate, the second coupling mounted on the mainplane wherein the second coupling can rotate. The second coupling element is connected to the flap via an oscillating support. The crank is arranged wherein the rotation direction of the crank for extension of the flap corresponds to the rotation direction of the crank for the trailing-edge flap of the starboard wing of the mainplane, with the rotation direction of the crank for the trailing-edge flap of the starboard wing being counterclockwise when viewed from the aircraft fuselage.
