Abstract: Methods and systems are provided to wrap a faired tether around a drum. The tether may be connected to an aerial vehicle. The method may involve guiding a faired tether around an exterior surface of a drum, wherein the drum comprises a helical shaped step around the exterior surface that is configured to mate with at least part of the faired tether, and to stack subsequent layers of wrapped tether in a staggered manner along the longitudinal axis of the drum. The faired tether may be guided onto the step using one or more level winds.
