## Abstract

This action raises the upper limit of Restricted Areas 6904A (R-6904A) and R-6904B, Volk Field, WI, from 17,000 feet above mean sea level (MSL) to Flight Level 230 (FL 230). Expanding the vertical limit of these areas facilitates the transition of participating aircraft between these restricted areas and the overlying Volk West Air Traffic Control Assigned Airspace (ATCAA). The additional airspace is needed to fulfill new United States Air Force (USAF) training requirements. This rule makes no other changes to R-6904A or R-6904B.
