## Abstract

This action modifies Class E airspace at Bloomington, IL. An Instrument Landing System (ILS) Standard Instrument Approach Procedure (SIAP) to Runway 20 has been developed for the Central Illinois Regional Airport at Bloomington-Normal (formerly the Bloomington/Normal Airport). Controlled airspace extending upward from 700 to 1200 feet above ground level (AGL) is needed to contain aircraft executing the approach. This action increases the radius of the existing Class E airspace.
