Distance Measuring Equipment (DME) is used to determine what?

Explanation:
Distance Measuring Equipment gives the distance from the aircraft to a ground station, expressed in nautical miles. It works by the aircraft interrogating the ground station and the station replying; the round‑trip time is converted into a distance. The readout represents the slant range—the direct line‑of‑sight distance between the airplane and the ground station. This information is commonly used with a VOR to determine your position by pairing a radial with a distance. DME does not provide horizon distance, temperature, or wind speed.
