What does VOR represent in aviation?

VOR, or Very High Frequency Omni-directional Range, is a type of radio navigation system used in aviation. It allows aircraft to determine their position and stay oriented while in flight. The system operates in the VHF frequency band and provides accurate azimuth information to pilots, helping them navigate along specific airways. This makes it an essential part of modern flight operations, enabling pilots to track their course relative to ground stations.

Understanding the components of VOR is crucial for pilots and dispatchers. The "Very High Frequency" refers to the range of radio frequencies that the VOR system uses, specifically within the range of 108 to 118 MHz. The "Omni-directional" aspect indicates that these signals are broadcast in all directions from the ground station, allowing pilots to receive navigation signals regardless of their position relative to the ground station.

Other options, such as Variable Orientation Radio, Varying Operational Range, and Vertical Omnidirectional Radio, do not convey the correct technical meaning and purpose of VOR in the context of aviation navigation. Using VOR equipment correctly contributes to safe and efficient flight planning and execution.
