What is DME an abbreviation for?

Distance Measuring Equipment is the correct interpretation of the acronym DME. This system plays a crucial role in aviation navigation, providing pilots with precise information regarding their distance from a specified navigation point, typically a VOR (VHF Omnidirectional Range) station. The DME unit transmits a signal that is received by ground equipment, which calculates the time it takes for the signal to make a round trip. By determining the distance from the ground-based station, it assists pilots in navigation and situational awareness during flight.

The other options, while they may seem plausible, do not accurately describe what DME represents in the context of aviation technology. Understanding the correct definition is essential for pilots, as DME is commonly used in flight planning, approaches, and maintaining navigation proficiency.
