What is the function of a VHF Omni-Directional Range (VOR) navigational aid?

The function of a VHF Omni-Directional Range (VOR) navigational aid is primarily to determine position and maintain course. VOR provides pilots with a way to navigate by broadcasting a signal that allows aircraft to determine their bearing from the station.

This navigation aid operates by sending out signals that pilots can receive, allowing them to pinpoint their location relative to the VOR station. By knowing both the location of the VOR and the bearing they are on, pilots can maintain their course accurately. The system's design facilitates real-time navigation, enabling pilots to make adjustments as needed to stay on their intended flight path.

While live weather updates, flight planning and route selection, and communication with air traffic control are critical components of aviation operation, they are not the primary functions of a VOR. Instead, the VOR system is dedicated to providing directional information to support navigation.
