What aspect of a VOR system increases the likelihood of navigation errors if not addressed?

The aspect of a VOR (VHF Omnidirectional Range) system that significantly increases the likelihood of navigation errors if not addressed is reverse sensing. This phenomenon occurs when a pilot misinterprets the VOR indication due to the aircraft's positioning relative to the VOR station. Essentially, if the pilot is flying towards the station but mistakenly believes they are flying away from it, they may follow navigation instructions incorrectly, leading to serious navigation errors.

Ensuring that pilots are aware of the risks associated with reverse sensing, particularly when navigating by VOR, is crucial. This awareness helps mitigate the chance of misinterpretation of the VOR signals, allowing for more accurate navigation and an overall reduction in the potential for navigational errors. Understanding and recognizing this issue is essential in training and in-flight operations to maintain safety and efficiency in navigation.
