What is a VOR facility?

A VOR facility, which stands for VHF Omni-directional Range, is a type of radio navigation system for aircraft that allows pilots to determine their position and stay on course. It works by transmitting a signal that includes directional information, enabling pilots to receive guidance for navigation. This accuracy in directional information is crucial for aircraft as it helps ensure safe and efficient flight paths, especially when flying under instrument flight rules.

While the other options mention various aspects of aviation and navigation, they do not accurately define what a VOR facility does. For example, enhancing visual flight rules relates to flight aspects that are separate from the VOR's role in providing navigational aids. Weather forecasting systems specifically assist pilots in planning and making operational decisions but do not provide directional navigation. Lastly, the VOR system is not strictly for maritime use; it is primarily designed for aviation and plays no direct role in maritime navigation, even though some principles may overlap.
