In this paper, we propose a novel wireless backhaul architecture, mounted on an aerial platform, and enabled by an active reconfigurable intelligent surface (RIS). We assume that an immediate traffic increase occurs in urban area, and to serve the ground users therein authorities rapidly deploy unmanned-aerial-vehicle base-stations (UAV-BSs). We efficiently optimize the phase and the 3D placement of aerial active RIS, which leads to an increase of energy-efficiency under guaranteeing the reliable link quality. We verify the performance of the proposed algorithm via extensive numerical evaluations.
