Modification of the Memphis International Airport Class B Airspace Area; TN

This action modifies the Memphis International Airport (MEM) Class B airspace area. Specifically, this action reconfigures existing sub-area boundaries, adds one new sub-area, and lowers the floor of Class B airspace in certain segments of the Memphis Class B airspace area. In addition, this modification redescribes the boundaries of the Memphis Class B airspace area using the Memphis Very High Frequency Omnidirectional Range Tactical Air Navigation (VORTAC) facility as the reference point. The FAA is taking this action to more efficiently align the Memphis Class B airspace area to accommodate simultaneous parallel instrument landing system (ILS) approach procedures and simultaneous intersecting runway operations. This change will enhance safety, reduce the potential for midair collisions, and improve the management of air traffic operations in the Memphis terminal area. Further, this effort supports the FAA's National Airspace Redesign project goal of optimizing terminal and enroute airspace areas to reduce aircraft delays and improve system capacity.
