Selecting a navigation frequency.

ACS element text (the applicant demonstrates understanding of)

Selecting a navigation frequency.

Bottom line

Some aircraft have separate VOR and DME receivers, each of which must be tuned to the appropriate navigation facility. For a DME with its own frequency selector, use the frequency of the associated VOR/DME or VORTAC station. DME selection assures reception of azimuth and distance information from a common source when designated VOR/DME, VORTAC, ILS/DME, and LOC/DME are selected.
