Apparatuses and systems that use a variable displacement motor-pump (VDMP) to control the position of a hose of an aerial refueling system are disclosed. At VDMP displacements greater than required to hold a position of the hose, the VDMP operates in a motor mode to retract the hose. For lesser VDMP displacements, the VDMP operates in a pump mode to control extension of the hose. In accordance with some embodiments, a dual orifice conveys hydraulic fluid at varying rates depending upon the VDMP operational mode.
