Modification of Class E Airspace; Eagle River, WI

This action modifies Class E airspace Eagle River, WI. A Global Positioning System (GPS) Standard Instrument Approach Procedure (SIAP) to Runway 04 has been developed for Eagle River Union Airport. Controlled airspace extending upward from 700 to 1200 feet above ground level (AGL) is needed to contain aircraft executing the approach. This action adds an extension to the southwest of the existing Class E airspace at Eagle River, WI. The intended effect of this action is to provide segregation of aircraft using instrument approach procedures in instrument conditions from other aircraft operating in visual weather conditions.
