## Abstract

This action modifies Class E airspace at Sheridan, IN. A Global Positioning System (GPS) Standard Instrument Approach Procedure (SIAP) to Runway (Rwy) 05, and a GPS SIAP to Rwy 23, have been developed for Sheridan Airport. Controlled airspace extending upward from 700 to 1200 feet above ground level (AGL) is needed to contain aircraft executing the approaches. This action increases the radius of the existing controlled airspace for this airport.
