What does VOR stand for in aviation navigation?

VOR stands for VHF Omnidirectional Range, which is a type of radio navigation system for aircraft. This system uses ground-based radio beacons that emit signals on VHF frequencies. By receiving these signals, an aircraft can determine its position and direction relative to the VOR station. It provides pilots with a means to navigate accurately by allowing them to establish their bearings and navigate along defined airways.

The VOR system is essential for en route navigation, as it offers pilots reliable information regarding their course and distance from the station. The omnidirectional aspect means that the VOR provides information in all directions, allowing pilots to receive navigational guidance no matter their position relative to the VOR station.

Other options are either inaccurate descriptions or concepts unrelated to aviation navigation. The VHF frequency is critical for this navigation method because it ensures clear communication over long distances, making it suitable for en route navigation in various weather conditions. Understanding VOR and its function empowers pilots to enhance their situational awareness and improve their flight planning.
