Which acronym refers specifically to navigation beacons used for flights?

The choice referring specifically to navigation beacons used for flights is VOR, which stands for VHF Omni-directional Range. VOR is a type of radio navigation system enabling an aircraft to determine its position and stay on course by receiving signals from a network of ground-based stations. Each VOR station transmits a specific frequency, and pilots use onboard equipment to interpret these signals to assist in navigation.

This system is essential for providing precise navigation guidance to pilots, ensuring safe and efficient flight operations. In contrast, VFR (Visual Flight Rules) pertains to regulations under which pilots fly in visually controlled airspace; VLOS (Visual Line of Sight) is a term often used in the context of drone operations, signifying that the operator must maintain visual contact with the drone during flight; and VR (Virtual Reality) has no relation to aerial navigation and is more commonly associated with immersive digital experiences. Thus, VOR is clearly the appropriate choice concerning navigation beacons for flights.
