What does VOR stand for in aviation?

In aviation, VOR stands for Very High Frequency Omnidirectional Range. This is a type of radio navigation system used by aircraft to determine their position and stay on course. The VOR operates in the VHF airband, which allows it to provide a continuous signal in all directions from the station, hence "omnidirectional."

VOR stations transmit powerful radio signals that allow pilots to receive bearings easily. By using onboard navigation equipment, pilots can read the heading to the VOR station, which helps them navigate to or from the station or along a flight path defined by the station. This system is essential for en route navigation and IFR (Instrument Flight Rules) operations, providing clear and precise guidance.

Understanding VOR is fundamental for pilots and is part of the training needed to ensure safe navigation in the airspace. Other options presented do not reflect established terminology within aviation navigation systems and therefore do not accurately describe what VOR means.
