What does DME stand for?

Explanation:
DME stands for Distance Measuring Equipment. It’s a radio navigation aid that determines the distance from the aircraft to the DME ground station by measuring the round-trip time of interrogations and replies, and it displays that distance in nautical miles. This equipment is usually paired with a VOR or an ILS (forming VOR/DME or ILS/DME), giving you both a course reference and a distance to help pin down your position and assist in sequencing and approach planning. The other phrases don’t reflect the established aviation term for this system, so they aren’t used in navigation terminology.
