What does the acronym VOR stand for, and what is its primary use?

The correct answer is that VOR stands for VHF Omnidirectional Range, and its primary use is for navigation. VOR is a type of radio navigation system for aircraft that enables pilots to determine their position and stay on course by receiving radio signals from ground stations. These stations transmit signals in all directions, providing a 360-degree reference of bearings. Pilots can use this information to navigate along airways, conduct instrument approaches, and safely arrive at their destinations.

This navigation method is particularly effective because it operates in the VHF frequency range, which allows for clear signal transmission and reception over considerable distances under various weather conditions, making it a reliable resource for pilots in both en-route navigation and approach phases of flight.
