A leading edge high lift assembly for a wing for an aircraft comprising a main wing, said leading edge high lift assembly comprising a leading edge high lift body, and a connection assembly for movably connecting the leading edge high lift body to the main wing, such that the leading edge high lift body can be moved between a retracted position and at least one extended position, wherein the connection assembly comprises a first connection element and a second connection element, wherein the first connection element is movably mountable to the main wing and is mounted to the leading edge high lift body, and wherein the second connection element is movably mountable to the main wing and is mounted to the leading edge high lift body in a position spaced apart from the first connection element in a wing span direction, wherein the connection assembly comprises a drive system that is mountable to the main wing and connected to the leading edge high lift body for driving the leading edge high lift body between the retracted position and the extended position, wherein the drive system comprises a first drive unit and a second drive unit spaced apart from one another in the wing span direction, wherein the first drive unit has a first input section coupled to a drive shaft, a first gear unit and a first output section coupled to the first connection element, and wherein the second drive unit has a second input section coupled to the drive shaft, a second gear unit, and a second output section coupled to the second connection element, wherein the first output section comprises a first output wheel and the second output section comprises a second output wheel, wherein the drive system comprises a sync arrangement coupling the first output section to the second output section for sync movement of the first and second output sections (37, 43), wherein the sync arrangement comprises a first sync wheel, a second sync wheel, and a sync shaft fixedly connecting the first sync wheel to the second sync wheel, wherein the first sync wheel is configured to be driven by the first output wheel and the second sync wheel is configured to be driven by the second output wheel, characterized in that the first sync wheel is configured to engage the first output wheel and the second sync wheel is configured to engage the second output wheel, when the first and second output wheels (45, 47) rotate synchronously, while the first sync wheel is configured to disengage from the first output wheel and/or the second sync wheel is configured to disengaged from the second output wheel, when the first and second output wheels (45, 47) rotate asynchronously. a leading edge high lift body, and a connection assembly for movably connecting the leading edge high lift body to the main wing, such that the leading edge high lift body can be moved between a retracted position and at least one extended position, wherein the connection assembly comprises a first connection element and a second connection element, wherein the first connection element is movably mountable to the main wing and is mounted to the leading edge high lift body, and wherein the second connection element is movably mountable to the main wing and is mounted to the leading edge high lift body in a position spaced apart from the first connection element in a wing span direction, wherein the connection assembly comprises a drive system that is mountable to the main wing and connected to the leading edge high lift body for driving the leading edge high lift body between the retracted position and the extended position, wherein the drive system comprises a first drive unit and a second drive unit spaced apart from one another in the wing span direction, wherein the first drive unit has a first input section coupled to a drive shaft, a first gear unit and a first output section coupled to the first connection element, and wherein the second drive unit has a second input section coupled to the drive shaft, a second gear unit, and a second output section coupled to the second connection element, wherein the first output section comprises a first output wheel and the second output section comprises a second output wheel, wherein the drive system comprises a sync arrangement coupling the first output section to the second output section for sync movement of the first and second output sections (37, 43), wherein the sync arrangement comprises a first sync wheel, a second sync wheel, and a sync shaft fixedly connecting the first sync wheel to the second sync wheel, wherein the first sync wheel is configured to be driven by the first output wheel and the second sync wheel is configured to be driven by the second output wheel, characterized in that the first sync wheel is configured to engage the first output wheel and the second sync wheel is configured to engage the second output wheel, when the first and second output wheels (45, 47) rotate synchronously, while the first sync wheel is configured to disengage from the first output wheel and/or the second sync wheel is configured to disengaged from the second output wheel, when the first and second output wheels (45, 47) rotate asynchronously.
