Update on VOR Decommissioning

The FAA has updated its plans to shut down about 311 VORs (about 30% of the existing network of 873 navaids) by 2025. About 585 VORs will remain in the minimum operational network (MON).

I went through the list of VORs that have been shut down and those scheduled to be decommissioned through September 2018. This PDF includes links to each navaid at SkyVector so that you can see them on a chart.

Note that in all cases, several nearby VORs remain active. Some of the VORs retain the DME feature and remain named fixes that you can file and use (with GPS–or DME).

The primary impact of the shutdowns would seem to be VOR-based approaches and perhaps departure procedures. Low altitude Victor airways, where necessary, are being supplanted with T-routes.

As the slide below shows, most of the VORs set to be decommissioned are in the Eastern and Central regions; only 15 navaids in the Western region are on the list.

To see the full list of VORs on the shutdown list, visit this entry at BruceAir. For more information about the process that FAA follows, see this explanation at AOPA. More information is available in the FAA Navigation Programs Strategy (PDF).

VOR-Mon-Chart-April 2018

At the April 25-26, 2018 meeting of the Aeronautical Charting Forum (complete meeting minutes as PDF here), a representative of the VOR MON Program Office described progress on the plan (full presentation as PDF here). Here are some highlights:

  • As of April 2018, 23 VORs have been decommissioned (see list below).
  • 15 more VORs will be shut down by the fall of 2018 (see list below).
  • FAA is upgrading the remaining VORs to support a standard service volume of 70 nm at 5000 AGL.

The FAA plans to increase the standard service volume (SSV) of the VORs that remain in the MON. Specifically, SSV at 5000 AGL will increase from the present 40 nm to 70 nm to support IFR navigation during a GPS outage. The following slides compare VOR coverage under the current standard with coverage using the new SSV.
