What is a key limitation of VOR navigation?

• A. Cone of confusion
• B. Requires GPS for accuracy
• C. Too sensitive to altitude changes
• D. Limited to daytime use

Answer: (A)

The cone of confusion is a significant limitation of VOR (VHF Omnidirectional Range) navigation. This phenomenon occurs near the VOR station where the signal is not well-defined, resulting in potential confusion for the pilot. Within this area, the VOR may not provide reliable heading information, leading to a lack of directional reference. As a result, pilots may have difficulty determining their position or course, particularly when flying close to the VOR station or in a situation where they expect precise guidance. The other options do not accurately describe limitations of VOR navigation. While VOR does not require GPS for operation, it can work independently, though using GPS may enhance navigation accuracy. VOR systems are generally robust to altitude changes, meaning a pilot’s altitude does not significantly affect the navigation signal under normal circumstances. Lastly, VOR systems can be used day or night, establishing that they are not limited to daytime operation. Thus, the cone of confusion is indeed a critical aspect to consider when using VOR for navigation.
