What is the purpose of the VOR Minimum Operational Network (MON)?

The purpose of the VOR Minimum Operational Network (MON) is to provide a balance between modern navigation technology and traditional systems. By strategically decommissioning select VORs while maintaining a smaller network, the MON ensures that there is a reliable backup navigation system in place. This is crucial for pilots who may still rely on VOR technology as a fallback in case of GPS failure or other navigational issues.

The MON aims to save costs by eliminating redundant VOR stations that are not essential for maintaining safety, all while ensuring there is sufficient coverage for the needs of aviation operators. The presence of the MON highlights the FAA's adaptation to evolving navigation technologies while still prioritizing safety in the airspace system. This option reflects an understanding of the shift from ground-based navigation aids to satellite-based systems, with contingency measures to support pilot safety and operational efficiency.
