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

A VOR (VHF Omnidirectional Range) is primarily designed to assist pilots in navigation by enabling them to determine their bearing from the VOR station. It operates by transmitting signals in all directions, which allows a pilot to pinpoint their position relative to the VOR station and navigate accordingly. When a pilot tunes their receiver to a VOR frequency, they can receive a course deviation indicator that tells them how to adjust their heading to follow a specific radial, enabling precise navigation.

The other options suggest functions that do not align with the primary capabilities of a VOR. While communication devices are essential for relaying information, VORs do not serve this purpose directly. Traffic control systems involve managing aircraft movements in airspace and are handled by air traffic controllers, not by VOR technology. Although weather information is crucial for flight safety, it is not part of the VOR's function, as it does not provide meteorological data. Therefore, the accurate role of the VOR is strictly related to helping determine bearing and navigation.
