Establishment of Class E5 Airspace at Afton Municipal Airport, Afton, WY

This action will establish Class E5 airspace at Afton, WY. Recently developed Area Navigation (RNAV)/Global Positioning System (GPS) Standard Terminal Arrival Routes (STARs) and Departure Procedures (SIDs) have made this proposal necessary. The establishment of Class E5 airspace is for containment of aircraft executing Instrument Flight Rule (IFR) operations at Afton Municipal Airport within controlled airspace. The intended effect of this action is to provide an increased level of safety for aircraft executing IFR operations between the terminal and en route phase of flight at Afton Municipal Airport, Afton, WY.
