VOR and DME are both acronyms (VOR being a compound

No. How do you pronounce "DME" as a word? "NASA" is an acronym. "RADAR"
is an acronym. DME is not, although it is an abbreviation.

VOR - Very High Frequency Omni-directional Range
DME - Distance Measuring Equipment

Abbreviations, not acronyms.

My dictionary doesn't say anything about pronouncing an acronym as a word.

Abbreviation: a shortened form of a word or phrase used for brevity

Acronym: A word formed from the initial letter or letters of each of the
successive parts or major parts of a compound term.
