What is a limitation of VOR systems?

The cone of confusion is a significant limitation of VOR (VHF Omni Range) systems. This phenomenon occurs because VOR signals can lack clarity in areas where the signal is equidistant from two VOR stations, leading to ambiguity about the aircraft's position. In these areas, pilots may struggle to determine their exact bearing or radial due to multiple overlapping signals, which can cause confusion regarding the aircraft's orientation. Understanding the cone of confusion is crucial for pilots to navigate effectively, as it can impede their ability to use VOR systems for accurate positioning, especially in regions where VOR stations are not closely spaced or when flying at low altitudes.

In contrast, aspects like excessively long signal ranges, inability to ascertain altitude, and reliance on satellite signals are not characteristic limitations of traditional VOR systems. Rather, these factors may pertain to different navigation technologies or other aspects of aviation navigation systems.
