Amendment of Class E Airspace, Blue Mesa, CO

This action amends Class E en route domestic airspace extending upward from 1,200 feet above the surface near the Blue Mesa VHF Omni-Directional Radio Range/Distance Measuring Equipment (VOR/ DME), Blue Mesa, CO. The FAA has transitioned to a more accurate method of measuring, publishing, and charting airspace areas that has revealed some small areas of uncharted uncontrolled airspace. The FAA found modification of these areas of uncontrolled airspace necessary to ensure the safety of Instrument Flight Rules (IFR) operations and the efficient use of navigable airspace, including point-to-point off-airway clearances, and aircraft vectoring services.
