A VOR receiver is an essential navigation instrument used in aviation. It stands for VHF Omnidirectional Range and helps pilots determine their position relative to a network of ground-based radio beacons. The receiver picks up signals from these beacons, allowing pilots to navigate accurately along specific flight paths. The VOR system provides directional information, which is displayed as a radial on the cockpit instruments. This enables pilots to fly to or from a VOR station, ensuring safe and efficient navigation. VOR receivers are widely used in both commercial and general aviation for route planning and in-flight navigation.
