On non-RNAV procedures, the VDP must also be identified by a DME fix
using the same DME source as other fixes in the final segment.
You want me to do what?" You didn't say it aloud, but you may well have been thinking it when the controller directed, "N12345, hold northeast of XYZ on the 050 radial, 20 DME fix
