In aviation, what does the acronym DME stand for?

In aviation, the acronym DME stands for Distance Measuring Equipment. This is a navigational aid that allows pilots and air traffic controllers to determine the distance between an aircraft and a ground station (DME station) by measuring the time it takes for a signal to travel from the aircraft to the ground station and back. This information is crucial for navigation, helping pilots maintain situational awareness and ensure they are on the correct flight path.

The DME provides distance information that is displayed in nautical miles, enabling more precise aircraft positioning and enhancing safety in both en-route and instrument approach phases of flight. Its functionality integrates seamlessly with other navigation systems, improving overall accuracy in aviation operations.
