Systems and methods for controlling flexible communication links used for aircraft refueling are disclosed. A system in accordance with one aspect of the invention includes a support configured to be carried by an aerial refueling aircraft, and a motion control device carried by the support. A movable aerial refueling boom is positioned proximate to the support and carries an aerial refueling line. A flexible communication link is carried by the boom and is movable with the boom relative to the support. The flexible communication link is coupled to the motion control device wherein the motion control device limits relative motion between the flexible communication link and the support. In particular embodiments, the flexible communication link can include a hydraulic hose or a cable, and the motion control device can include a spring or other forcing member positioned to rotationally urge the flexible communication link toward the support.
