What is the function of the VOR equipment?

• A. Air traffic surveillance
• B. Communication
• C. Navigation
• D. Weather sensing

Answer: (C)

VOR is a radio navigation aid that provides directional information to help pilots determine their bearing relative to a ground station. It uses VHF signals to emit a reference signal plus a rotating signal, and the aircraft’s navigation equipment compares them to determine the magnetic bearing (the radial) from the station. This information is used to navigate—plotting courses, maintaining a chosen radial, and fixing position when combined with other data. It does not perform air traffic surveillance (that’s radar), it doesn’t handle voice or data communication, and it doesn’t sense weather (that’s separate weather sensing equipment). If you need distance, VOR is often paired with DME to give range, but the core function of VOR itself is to aid navigation through bearing information.
