## Abstract

Sioux Gateway Airport, Sioux City, IA, has been renamed Sioux Gateway/Col. Bud Day Field. An examination of controlled airspace for Sioux City, IA revealed discrepancies in the Sioux Gateway/Col. Bud Day Field airport reference point used in the legal descriptions for the Sioux City, IA Class D and Class E airspace areas. The intended effect of this rule is to replace "Sioux Gateway Airport" in the legal descriptions of Sioux City, IA Class D and Class E airspace areas with "Sioux Gateway/Col. Bud Day Field," to incorporate the current Sioux Gateway/Col. Bud Day Field airport reference point into the legal descriptions of these airspace areas and to bring the legal descriptions into compliance with FAA Orders.
