## Abstract

This action modifies Class D airspace, Class E surface area airspace, Class E airspace extending upward from 700 feet above the surface, and Class E airspace extending upward from 1,200 feet above the surface at Cheyenne Regional/Jerry Olson Field Airport (formerly, Cheyenne Airport), Cheyenne, WY. Airspace redesign is necessary due to the decommissioning of the Cheyenne instrument landing system (ILS) locator outer marker and removal of the Cheyenne VHF Omnidirectional Range/Tactical Air Navigation (VORTAC) from the airspace description as the FAA transitions from ground-based navigation aids to satellite- based navigation. Also, this action updates the airport name and geographic coordinates for the associated Class D and E airspace areas to reflect the FAA's current aeronautical database, and makes an editorial change in the legal description by replacing Airport/Facility Directory with the term Chart Supplement.
