What does VOR stand for in aviation terminology?

VOR stands for VHF Omnidirectional Range, which is a type of radio navigation system for aircraft. It uses VHF (Very High Frequency) radio signals from a network of ground stations to provide pilots with accurate bearing information. The system allows aircraft to determine their position relative to the station and navigate accordingly using a VOR receiver in the cockpit.

The significance of VORs in aviation cannot be overstated, as they provide critical guidance for approach and departure paths, helping ensure safe navigation. The omnidirectional aspect means that the signals can be received from all directions, enabling pilots to use VORs for various navigation scenarios.

In the context of the other options, Variable Operational Radar and Vertical Orientation Reference do not reflect established terminology within aviation navigation, and Very High Frequency Omnidirectional Range inaccurately describes the system's name since the first word does not match the commonly recognized acronym in the field.
