A power spring (30) passively applies tension to a cable (16) connected to an aircraft refueling boom (12). The power spring has a first end engaging a fixed arbor (26) and second end engaging a rotatable spooling drum (20) around which a portion of the cable is wound. The power spring biases the drum to rotate in a winding direction to apply tension to the cable, and the power spring stores energy when the drum rotates in an unwinding direction. The power spring may be located inside the drum or outside the drum. The drum may be actively driven by a motor (32) that may be uncoupled from the drum to permit freewheeling rotation of the drum, wherein the power spring continues to apply tension to the cable. The invention eliminates reliance on one or more powered motors for removing unwanted slack in the cable.
