Which is true regarding the VOR changeover point on air route navigation?

The VOR changeover point is a critical concept in air route navigation. It marks the point along your flight path where the aircraft transitions from using the signal of one VOR (VHF Omnidirectional Range) station to another. This is particularly important for pilots who are navigating along airways that are often served by multiple VOR stations.

The changeover point is calculated based on the distance from each VOR station and is usually determined by guidelines set forth in aeronautical navigation charts. As you approach this point, the signals from the second VOR begin to take precedence, allowing for a seamless transition to the new navigation aid. This ensures that pilots maintain accurate positional awareness and can navigate effectively without interruption in their route.

Understanding the concept of the VOR changeover point helps pilots in planning their flight path and ensuring safe navigation when switching from one VOR signal to another. It is not related to the locations of airports, altitude levels, or solely the destination distance, which highlights the specific navigational function of the changeover point in the context of using VOR signals during flight.
