What does the term "VOR" stand for in aviation?

The term "VOR" in aviation stands for VHF Omnidirectional Range. It is a type of radio navigation system that allows pilots to determine their aircraft's position and stay on course. The VOR system operates in the very high frequency (VHF) range of radio frequencies, which provides dependable navigation signals that can be received by aircraft over considerable distances.

The VOR system consists of ground-based transmitters that emit signals which pilots can use in conjunction with their aircraft's VOR receivers. By tuning into the appropriate frequency, pilots can receive radial information, which helps them navigate along specific flight paths.

This system is widely used for its reliability and accuracy in navigation, helping ensure safety in both instrument flying and general aviation. Understanding VOR systems is critical for pilots who are conducting IFR flights, as it provides essential navigational information in low-visibility conditions.
