Amendment to Class E Airspace; Des Moines, IA

This action amends Class E airspace area at Des Moines International Airport, Des Moines, IA. A review of the Class E airspace area for Des Moines International Airport indicates it does not comply with the criteria for 700 feet Above Ground Level (AGL) airspace required for diverse departures as specified in FAA Order 7400.2D. The Airport Reference Point (ARP) coordinates are revised, and the Instrument Landing System (ILS) and coordinates have been added to the airspace designation for Des Moines, IA. The Class E airspace has been enlarged to conform to the criteria of FAA Order 7400.2D. The intended effect of this rule is to provide additional controlled Class E airspace for aircraft operating under Instrument Flight Rules (IFR), revise the ARP, add the ILS and coordinates, and comply with the criteria of FAA Order 7400.2D.
