Action
Notice of proposed rulemaking (NPRM).
Summary
This action proposes to amend three low altitude United States Area Navigation (RNAV) routes, designated T-224, T-258, T-323, and establish ten new low altitude RNAV routes, designated T-404, T-406, T- 408, T-410, T-412, T-414, T-423, T-425, T-427, and T-429, in the eastern United States. The proposed routes would enhance the efficiency of the National Airspace System (NAS) by expanding the availability of RNAV routing and supporting the transition of the NAS from ground-based to satellite-based navigation, under the VHF Omnidirectional Range (VOR) Minimum Operational Network (MON) program.
