Notice of proposed rulemaking (NPRM).

This action proposes to establish area navigation (RNAV) routes T-301 and T-305 in the northcentral United States. The proposed new RNAV routes would expand the availability of RNAV routing in support of transitioning the National Airspace System (NAS) from ground-based to satellite-based navigation. Additionally, a portion of the new RNAV routes would provide enroute structure where VHF Omnidirectional Range (VOR) Federal airway segments were removed due to the Cape Girardeau, MO, VOR being decommissioned in support of the FAA's VOR Minimum Operational Network (MON) program.
