Amendment of Class E Airspace; Manitowoc and Sheboygan, WI

This action modifies the Class E airspace extending upward from 700 feet above the surface at Manitowoc County Airport, Manitowoc, WI, and Sheboygan County Memorial Airport, Sheboygan, WI. This action is due to an airspace review caused by the decommissioning of the Manitowoc VHF omnidirectional range (VOR), which provided navigation information to the instrument procedures at these airports, as part of the VOR Minimum Operational Network (MON) Program. The geographic coordinates of Sheboygan County Memorial Airport are also being updated to coincide with the FAA's aeronautic database. Airspace redesign is necessary for the safety and management of instrument flight rules (IFR) operations at these airports.
