Distance Measuring Equipment ('''[[DME]]''') uses the same frequencies as a [[VOR]]. A DME tells the equipment on board of the aircraft the distance towards the transponder. There is two-way communication between the equipment on-board and the DME station to calculate the result.

While a [[VOR]] can be a stand-alone beacon, a DME will be paired with a [[VOR]], a '''VOR-DME'''. Both senders will contain information about the other and tuning will be automatic. If the [[VOR]] station (of a VOR-DME) fails it defaults to a stand-alone [[DME]].
