Modification of Class E Airspace; Pinckneyville, IL, Pinckneyville-DuQuoin Airport

Streszczenie

This notice proposes to modify Class E airspace at Pinckneyville, IL. A Global Positioning System (GPS) standard instrument approach procedure (SIAP) to Runaway 18 and a GPS SIAP to Runway 36 have been developed for Pinckneyville-DuQuoin Airport. 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 proposal is to provide segregation of aircraft using instrument approach procedures in instrument conditions from other aircraft operating `in visual weather conditions.
