What range does a high altitude VOR station provide from 18000 to 45000 feet?

High altitude VOR stations are designed to provide navigation assistance at elevated altitudes, specifically designed for aircraft operating at or above 18,000 feet. The range of these VOR stations is significantly greater than that of regular VOR stations.

In the case of high altitude VOR stations, they can provide coverage up to 130 nautical miles (nm) from the station when an aircraft is between 18,000 feet and 45,000 feet. This extended range is crucial for aircraft operating in high altitude environments, particularly those traversing long distances and engaged in airways that necessitate reliable navigation signals. Understanding this range is fundamental for pilots, as it aids in planning routes and ensuring they remain within usable coverage areas of navigational aids during flight operations.

By recognizing the capabilities of high altitude VOR stations, pilots can make informed decisions regarding their navigation and flight planning while operating in the upper flight levels.
