## Abstract

This action amends the Class E airspace area at Ankeny, IA. The FAA has developed Instrument Landing System (ILS) Runway (RWY) 36 ORIGINAL Standard Instrument Approach Procedure (SIAP), Area Navigation (RNAV) Global Positioning System (GPS) RWY 18 ORIGINAL SIAP and RNAV (GPS) RWY 22 ORIGINAL SIAP to serve Ankeny Regional Airport at Ankeny, IA. Additional controlled airspace extending upward from 700 feet Above Ground Level (AGL) is needed to accommodate the SIAPs and for other Instrument Flight Rules (IFR) operations at this airport. The intended effect of this rule is to provide controlled Class E airspace for aircraft executing the SIAPs and to segregate aircraft using instrument approach procedures in instrument conditions from aircraft operating in visual conditions.
