In aviation navigation, what does the acronym VOR stand for?

The acronym VOR stands for Very High Frequency Omni Directional Range. This terminology is integral to aviation navigation, specifically referring to a type of radio navigation system for aircraft. A VOR station transmits a signal in all directions, allowing pilots to determine their position relative to the station and navigate accordingly.

By using a VOR receiver in the aircraft, pilots can identify the specific radial they are on, which helps in course plotting and navigation over long distances. The terminology emphasizes the frequency band in which it operates (very high frequency, or VHF) and its capability to provide directional information (omnidirectional), making it a fundamental tool for both pilots flying under visual flight rules (VFR) and instrument flight rules (IFR). This understanding is crucial for safe and effective navigation in aviation.
