Modification of Class E Airspace; Lawrenceville, IL

This action modifies Class E airspace at Lawrenceville, IL. A Very High Frequency Omnidirectional Range/Distance Measuring Equipment (VOR/DME) Standard Instrument Approach Procedure (SIAP) to Runway 18 and a VOR/DME SIAP to Runway 36 have been developed for Lawrenceville- Vincennes International Airport because of relocation of the Lawrenceville VOR/DME. Controlled airspace extending upward from 700 to 1200 feet above ground level (AGL) is needed to contain aircraft executing the approach. This action adds an extension to the northeast of the existing Class E airspace for the Lawrenceville-Vincennes International Airport. The intended effect of this action is to provide segregation of aircraft using instrument approach procedures in instrument conditions from other aircraft operating in visual weather conditions.
