Latest Update on VOR Decommissioning Program
December 14, 2015 4 Comments
The latest update from FAA on its plans to decommission VORs includes the following details:
- Decommission approximately 30% (308) of the current 957 VORs by 2025
- 74 VORs will be shut down during phase 1 (FY2016 through FY2020)
- Another 234 VORs will be decommissioned during phase 2 (FY2021 – FY2025)
- Of the 308 VORs to be shut down, 15 will be in the West, 162 in the central U.S., and 131 in the East.
- 649 VORs will remain in operation after 2025, forming the minimum operational network (MON).
The goals established for the MON include allowing pilots to:
- Revert from PBN to conventional navigation in the event of a Global Positioning System (GPS) outage;
- Tune and identify a VOR at an altitude of 5,000 feet or higher;
- Navigate using VOR procedures through a GPS outage area;
- Navigate to a MON airport within 100 nautical miles to fly an Instrument Landing System (ILS) or VOR instrument approach without Distance Measuring Equipment (DME), Automatic Direction Finder (ADF), surveillance, or GPS; and
- Navigate along VOR Airways especially in mountainous terrain where surveillance services are not available and Minimum En Route Altitudes (MEAs) offer lower altitude selection for options in icing conditions.
Progress will be slow initially. Only 5 VORs are to be shut down by September 2016. Another 4 navaids will be decommissioned by September 2017, followed by 4 more through September 2018. In 2019, FAA plans to shut down an additional 25 VORs, followed by 36 more in 2020.
Phase 2 begins in FY2021. A total of 234 VORs will be shut down through 2025.
