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

The primary purpose of a VOR (VHF Omnidirectional Range) is to assist pilots in navigation by providing bearing information. VOR stations emit signals that allow aircraft to determine their position relative to the station and to follow specific courses. By tuning into a VOR frequency, pilots can receive radial information and navigate along predefined routes using the azimuth provided by the VOR signal. This capability is essential for maintaining situational awareness and ensuring effective navigation, especially in situations where other visual cues may be absent, such as in low visibility conditions.

The other options do not accurately reflect the function of a VOR. For instance, while altitude information is crucial for air traffic control, it is not provided by VOR stations. Similarly, VORs do not provide any direct indications of weather conditions, nor do they play any role in managing an aircraft's fuel consumption. Their specific design and function are focused solely on navigation assistance.
