Proposed Establishment of Class E Airspace, Denver, CO
This action proposes to establish Class E en route airspace extending upward from 1,200 feet above the surface to accommodate Instrument Flight Rules (IFR) aircraft under control of the Denver Air Route Traffic Control Center (ARTCC), Denver, CO. Establishment of this airspace area would ensure controlled airspace exists in those areas where the Federal airway structure is inadequate.
