A supplemental notice of proposed rulemaking modifies previously proposed (Nov. 23, 2003) changes to the Minneapolis Class B airspace. This action proposes to add a new Area F to contain large turbine-powered aircraft within Class B airspace during operations on new Runway 17/35 at Minneapolis-St. Paul International Airport. Runway 17/35, which is 8,000 feet long, is scheduled to become operational on October 27. Meanwhile, the configuration of Los Angeles Class B airspace is set to change on December 22 to ensure that STAR routes are contained within the protected airspace and to “correct inefficiencies of several existing areas.” In addition, the shoreline transition route with multiple altitudes will be reinstated to allow pilots “to retain flight following at all times.”
