The only VC's I know of are the design cruising speed or the optimum cruise speed. FAR 25.335 and 23.335 talk about a minimum value for VC but never use the abbreviation VCmin that I can see.
"minimum control speed" is usally associated with the abbreviation "VMC" and it's sub-categories: Vmca, Vmcg, Vmcl. I've never seen "active" used in that context though.
Perhaps if you told us which aircraft it might right a bell for someone?
