What does a VOR provide during navigation?

A VOR, or VHF Omnidirectional Range, is a type of radio navigation system for aircraft that provides pilots with the necessary information for course navigation. Specifically, a VOR transmits a signal that allows aircraft to determine their bearing from the station, which is referred to as the course or radial. This information is crucial for pilots as it enables them to navigate by following specific courses to their destinations.

By indicating the direction to or from a VOR station, it helps pilots maintain a specific heading, which is essential for effective route planning and navigation. The VOR is designed to convey this radial information, allowing pilots to ascertain their position relative to the navigation aid.

While distance can be calculated using additional navigational tools or systems (such as DME - Distance Measuring Equipment), VOR itself does not provide distance information directly. Altitude data and speed information are also not provided by VOR; these require different types of instruments or navigation aids altogether. Therefore, the primary function of a VOR is to provide the essential directional information needed for navigation.
