Establishment of Class E Airspace; SD

This action establishes Class E airspace within the State of South Dakota, west of Winner, SD. This airspace action allows more flexibility for Part 135 and air ambulance operators and provides a safer environment for all aircraft flying in the described controlled airspace. Controlled airspace extending upward from 1200 feet above ground level (AGL) is needed to contain aircraft executing instrument flight rules (IFR) operations. The intended effect of this action is to provide segregation of aircraft using instrument procedures in instrument conditions from other aircraft operating in visual weather conditions.
