What is the purpose of a VOR (VHF Omnidirectional Range) system?

The VOR (VHF Omnidirectional Range) system is primarily utilized for navigation guidance. It is a radio navigation system that allows pilots to determine their position and track their course relative to a network of ground-based radio beacons. Each VOR station transmits a signal that indicates both the direction of the station from the aircraft's position and the path a pilot should follow.

By tuning into a specific VOR frequency, pilots can obtain their bearing from the VOR station, which is essential for navigation during both visual and instrument flying conditions. This system assists in route planning and ensures that pilots maintain the correct heading to reach their destination efficiently and safely.

In contrast, weather information is provided through different systems and reporting services. Communication with Air Traffic Control (ATC) is handled using radio frequencies, but it does not involve navigation signals or guidance mechanisms like those provided by the VOR. Monitoring fuel levels pertains to fuel management systems within the aircraft, which is unrelated to navigation functions.
