Abstract
This action modifies Class E airspace at Spearfish, SD. A Global Positioning System (GPS) standard instrument approach procedure (SIAP) to Runway 12 has been developed for Black Hills-Clyde Ice Field. Controlled airspace extending upward from 700 to 1200 feet above ground level (AGL) is needed to contain aircraft executing the approach. The intended affect of this action is to provide segregation of aircraft using instrument approach procedures in instrument conditions from other aircraft operating in visual weather conditions.
