1. An actuator arrangement for a fixed leading edge member, the fixed leading edge member having an inner cavity at least in part defined by an outer skin and a rib, the actuator arrangement being configured for extending and retracting at least one high-lift device attached to the fixed leading edge member, the actuator arrangement comprising:
a fixed leading edge lever configured for being attached to the fixed leading edge member,
a high-lift device lever configured for being attached to the high-lift device, and
an actuator assembly configured to drive the fixed leading edge lever and the high-lift device lever relative to each other, the actuator assembly including at least one actuator,
wherein the actuator assembly is configured such that, when the fixed leading edge lever and the high-lift device lever are attached to the high-lift device and the fixed leading edge member, respectively, the actuator is movable during extending and retracting of the high-lift device between a fully retracted position, in which the actuator is predominantly accommodated within the inner cavity, and a fully extended position, in which the actuator is predominantly positioned outside the inner cavity.
