Which statement about VOR is true?

• A. VOR uses low frequency signals.
• B. VOR provides only range information.
• C. VOR provides Very High Frequency Omnidirectional Range navigation signals for course guidance.
• D. VOR is a weather radar.

Answer: (C)

VOR provides azimuth information to steer your course. It uses Very High Frequency signals from a ground station to give you a bearing to or from that station, which you see as a course on the cockpit instrument (CDI). The system works by sending a reference signal plus a rotating signal; the angular difference between them is interpreted by the receiver as the aircraft’s bearing relative to the VOR, allowing you to fly a chosen radial for course guidance. It does not supply distance by itself—distance is not shown on the VOR indicator unless you pair it with DME, which provides slant-range information. Also, VOR operates in the VHF range, not low frequency, and it’s not weather radar.
