What is a key feature of the VOR Minimum Operational Network (MON)?

The VOR Minimum Operational Network (MON) is designed to ensure reliable VOR navigation coverage throughout the Continental United States (CONUS). A critical feature of this network is that it guarantees VOR coverage at an altitude of 5,000 feet above ground level (AGL). This altitude is significant because it allows for effective navigation by ensuring that pilots have reliable navigational signals in a variety of flight scenarios, particularly in areas where terrain or other obstacles might inhibit signal reception at lower altitudes.

This focus on providing coverage at 5,000 feet AGL allows pilots to utilize VOR navigation tools more effectively, enhancing safety and reliability during flight operations, particularly in areas where alternative navigation aids may not be available. The establishment of these coverage levels supports not only flight safety but also helps reduce the potential for navigational errors during transitional phases of flight.

In contrast, other options do not accurately define the features of the VOR MON. For instance, the requirement for a 10,000-foot AGL altitude or limitations to ILS approaches and military operations are not intrinsic to the MON, as its primary goal is to enhance VOR navigation capabilities for all aircraft operations within the specified regions.
