What does VOR navigation utilize in IFR operations?

VOR navigation is a fundamental aspect of IFR (Instrument Flight Rules) operations that specifically utilizes VOR stations to provide directional guidance to pilots. VOR, which stands for VHF Omni-Directional Range, is a type of radio navigation system that enables aircraft to determine their position and stay on course by receiving signals from these ground-based VOR stations. Each VOR station broadcasts a unique signal that the aircraft's navigation system can interpret to ascertain its heading relative to the station.

This system allows pilots to navigate along predetermined airways, known as VOR airways, which are essential for IFR operations where maintaining an accurate flight path is crucial, especially in poor visibility or adverse weather conditions. By tuning their navigation equipment to a specific VOR frequency, pilots can use the information provided by the VOR stations to follow their intended route safely and efficiently.
