Latest Update from FAA on Plans to Decommission VORs

Two representatives from the FAA recently provided an update on the agency’s plans to decommission VORs. The presentation, given at the FAA’s Aeronautical Charting Forum meeting on October 28-30, is available as a PDF in my Aviation Documents folder at OneDrive. The presentation largely recapped information described in briefings and white papers (described here, here, and here), but it did restate several key points and provide some new information.

Highlights from the latest presentation include:

  • The VOR MON Program will implement the [minimum operational network of VORs] by decommissioning 30-50% of the VORs in the NAS by 2025 (although the current plan retains all VORs in the designated mountainous region of the U.S.—roughly the western third of the country).
  • The reduction will begin gradually over the first five years during which time the bulk of the procedural/airway/airspace work will assessed. Then the plan is to accelerate the process, with 20-25 VORs shut down each year.
  • Only FAA owned/operated VORs will be considered for shutdown.
  • DMEs and TACANs will generally be retained.
  • Many of the remaining VORs will be enhanced to supply increased service volume. VOR standard service volume (SSV) will become 77 NM radius at 5000 ft. AGL.
  • Increase support for direct navigation between VORs without airways.
  • Retain sufficient ILSs, LOCs, and VORs to support “safe-landing” at a suitable destination with a GPS-independent approach (ILS, LOC or VOR) within 100 NM of any location within CONUS.
  • Provide seamless VOR coverage at and above 5000 ft AGL.
  • More than 5,000 instrument approaches may be affected by the reduction in operational VORs.
  • Nearly 1,300 SIDs, STARs, and ODPs may be affected by the reduction in operational VORs.
  • FAA is considering how to refer to and chart DME-only facilities.
  • Graphics in the presentation include a pair of maps that show how the current airway structure will be changed when the MON is established.

    Can someone please post a list (text) of the VORs scheduled or planned for decommissioning? The maps and graphics are useless.

      As far as I know, FAA has not released a list of VORs and other navaids that are scheduled to be decommissioned. They have provided only the details in the various presentations and plans that I’ve cited in my posts on this topic. The latest overall details that I’m aware of are in the Federal Radionavigation Plan, last issued in 2012. You can find editions of that plan here.
