## Abstract

This action amends VHF Omnidirectional Range (VOR) Federal airways V-9, V-63, V-100, V-158, and V-171; amends Area Navigation (RNAV) route T-325; and removes VOR Federal airway V-127 in the vicinity of Rockford, IL. The air traffic service (ATS) route modifications are necessary due to the planned decommissioning of the VOR portion of the Rockford, IL, VOR/Distance Measuring Equipment (VOR/ DME) navigational aid (NAVAID). Except for RNAV route T-325, the Rockford VOR/DME NAVAID provides navigation guidance for portions of the affected routes listed above. The Rockford VOR is being decommissioned as part of the FAA's VOR Minimum Operational Network (MON) program.
