Proposed Establishment of Class E6 Airspace, Tucumcari, NM

The National Business Aviation Association (NBAA) fully supports this proposal to further reduce the choke points and areas in our National Airspace System (NAS) caused by these small to large areas of Class G airspace, whether they have a top of 14,500, msl, or some other fixed altitude higher than 1,200 feet, agl. These Class G choke points and areas create an undue burden on the expansion of terminal instrument procedures, particularly in the inter-mountain west. These Class G choke points and areas also cause ARTCC minimum instrument altitudes (MIAs) to be increased to be within controlled airspace. This creates significant barriers to efficient Next Generation en route and terminal area performance-based navigation. We urge you to continue this initiative until Class E airspace everywhere in the continental United States is not higher than 1,200 feet, agl.
