Federal Aviation Administration May 14, 2010 – Federal Register Recent Federal Regulation Documents

This action proposes to modify the Chicago, IL, Class B airspace area by expanding the existing airspace to ensure containment of Instrument Flight Rules (IFR) aircraft conducting instrument approach procedures within Class B airspace, and segregating IFR aircraft at Chicago O'Hare International Airport (ORD) and Visual Flight Rules (VFR) aircraft operating in the vicinity of Chicago Class B airspace. Additional Class B airspace would support operations to ORD's triple parallel runways and three additional parallel runways planned for the near future. This action would enhance safety, improve the flow of air traffic, and reduce the potential for midair collision in the Chicago terminal area, further supporting the FAA's national airspace redesign goal of optimizing terminal and en route airspace areas to reduce aircraft delays and improve system capacity.
