What is a VOR in aviation?

A VOR, or Very High Frequency Omni Range, is a type of radio navigation system for aircraft that enables pilots to determine their position and stay on course. The system operates in the VHF frequency band and provides azimuth information, allowing pilots to navigate by tuning into ground stations that radiate signals in all directions.

VOR stations transmit a signal that pilots can use to identify their position relative to the station, helping them follow specific airways or routes. Each VOR station emits a unique signal, which pilots can identify and use to ensure they are flying correctly along their intended path. This capability is essential for maintaining safe and efficient navigation, especially in areas with limited visual reference points.

In contrast, the other options presented do not accurately describe the VOR system. Variable Operational Radar and Virtual Operational Range do not pertain to standard aviation terminology or navigation systems. Similarly, Visual Overlay Range is not relevant to VOR functionality, as a VOR is specifically designed for radio navigation rather than visual aids. Understanding the VOR’s role in aviation is crucial for navigation, particularly in instrument flying scenarios.
