Alternate Mins NA?
As the FAA is transitioning the National Airspace System (NAS) to Performance Based Navigation (PBN), more and more we see VORs becoming unmonitored or unserviceable. When a VOR is NOTAMed “unmonitored,” my understanding is that if you can identify it in the aircraft (Morse code) and have a good signal, you can use it. Where it becomes an issue is in preflight IFR planning—you cannot use an IAP that is based on the unmonitored VOR as an alternative for flight planning (although I could not find an AIM or FAR reference…).
