Краткое содержание

This action establishes Class E airspace areas at Waukegan Regional Airport, Chicago/Waukegan, IL, Purdue University Airport, Lafayette, IN, Lost Nation Airport, Willoughby, OH, Central Wisconsin Airport, Mosinee, WI, and La Crosse Municipal Airport, La Crosse, WI. Presently, these areas are designated as Class D airspace when the associated control tower is in operation. However, controlled airspace to the surface is needed when the control towers located at these areas are closed. The intended effect of this action is to provide adequate Class E airspace for instrument flight rule (IFR) operations when these control towers are closed.
