Note that Standard Service Volume (SSV) does not apply to airways as they've been certified at their respective distances.GS values, if displayed, are only accurate when flying directly to / from the station.If DME fails above FL 240, continue to next airport where repairs or equipment replacement can be done (must still report as per AIM 5-3-3).Required above FL 240 when VOR navigation required (under IFR) as per FAR 91.205(e).Can be identified every 30 seconds or about every 3rd to 4th VOR identification.

DME paired with a VOR constitutes a VORTAC.

DME is not available on a VOR and would require a separate receiver.

Due to the limited number of available frequencies, assignment of paired frequencies is required for certain military non-collocated VOR and TACAN facilities which serve the same area but which may be separated by distances up to a few miles.

Reliable up to 199 NM accuracy of better than 1/2 mile or 3% of the distance, whichever is greater (more accurate).Slant range error minimized at lower altitudes.Distance is measured in slant range (not horizontal range!) but some units can correct this.Time time it takes is interpreted as the distance, usually in Nautical Miles (NM).The ground station (transponder) sends the same pulses back to the aircraft at a different frequency.Paired pulses at specific spacing (interrogation) are sent to a ground station from the aircraft via the antenna.
