How does VOR/DME work for navigation?

• A. VOR provides azimuth information; DME provides distance (slant-range) to the beacon, enabling position fixes.
• B. DME distance only; VOR provides azimuth.
• C. VOR provides altitude; DME provides time to station.
• D. DME distance; VOR provides vertical guidance.

Answer: (A)

VOR/DME navigation works by giving you two pieces of information: azimuth and distance. The VOR provides azimuth, meaning you can determine the radial line from the station that you are flying on. The DME gives your distance to the station, measured in nautical miles (slant-range). By knowing both the bearing from the VOR and how far you are from the VOR/DME facility, you can fix your position relative to the beacon—often by seeing where a specific VOR radial crosses the DME distance circle. This combination lets you navigate to or from the station and follow published routes accurately. The other options mix up what VOR or DME provides: altitude or time data, vertical guidance, or distance without the azimuth, which aren’t correct descriptions of how VOR/DME works.
