Definition
Ground-based locations where VHF Omnidirectional Range (VOR) navigation transmitters are installed. These sites broadcast radio signals pilots use for navigation and are recognizable on the ground by their distinctive white, cone-topped or disc-shaped antenna structures, often situated in open, flat areas free of obstructions that could interfere with signal transmission.
Plain English
The physical locations on the ground where VOR navigation radio transmitters are built. They look like small white domes or cones sitting in clear, open ground.
Context Anchor
Seen in navigation and collision-avoidance discussions, especially when pilots are warned that aircraft may gather near navigation stations.
Derivation
VOR stands for VHF Omnidirectional Range. 'Site' simply means the chosen ground location. The word comes from Latin situs, meaning 'position' or 'place where something is set.'
Why Pilots Care
Proper siting prevents signal blockage or distortion that could lead to inaccurate course information during flight.
Grounding Statement
Picture a fixed radio station on the ground sending navigation signals outward while aircraft nearby use those signals to orient themselves.
Intuition Check
Do not read “site” as a website or just a named point on a chart. In this context, a VOR site is the actual ground location of a radio navigation station.
Example Sentence 1
While flying low over open terrain, the pilot spotted a VOR site ahead and adjusted course to avoid overflying the antenna.
Example Sentence 2
Maintenance crews ensure clear areas around VOR sites so the navigation signal remains usable for aircraft.
