Can someone explain me what do we mean by the term frequency pairing?
I met the term in an avionics book.The phrase is the following;
The DME interrogation and reply frequency are paired with VOR
frequency.
Thank you

That's it, just an assignment, so that when you tune the VOR
or ILS the DME tunes to the correct frequency.

The DME had to be tuned independently before they
established pairings.

VOR's are in the VHF band (108-118 mHz approx)
DME's are in the UHF band (up in the 400's mHZ)

When you tune a DME, the VHF frequency you enter on the device (or have
channeled to it from the nav) is a paired frequency, established years
ago by international convention.

Noooo...

VORs (plural, not possessive) are in the VHF band (108-118 MHz. exactly)
Glideslopes are in the UHF band (325 MHz. or so)
DMEs are in L band (1000 MHz or so)

It's even more complex than it first looks:

There are 200 VHF channels allocated for NAV/DME of which 40 are also
paired with the ILS. That means when you tune to a VHF NAV frequency
you also tune the DME transmitter, DME receiver and ILS receiver. Each
part of the system uses a separate range of frequencies but for
simplicity selecting one automatically selects the rest.

These are:

108-117.95MHz VOR/LOC
1041-1150MHz DME Transmitter
978-1213MHz DME Receiver
328-336 MHz Glideslope Receiver
(Glideslope selected by the VHF range up to 111.95MHz)

Being mere pilots all we need to know is when you tune the NAV
everything else should follow as it is 'paired'.

David

Thanks Jim...

I know I can count on you to keep me straight when I fudge radio stuff a
little bit.

Actually, the apostrophe is NOT incorrect here if you consider VOR
to be a grouping of letters (abbreviation) rather than a acronym
(a word made out of the abbreviation). Certainly DME is not an
acronym. The rules of usage allow don't really favor one or the
other.

VOR and DME are both acronyms (VOR being a compound
acronym).

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

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.

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.

An acronym is not a word. Like Bob said there is no requirement that an
acronym be pronouncable, . For detailed references, troop down to your local
library (or branch) and peruse the Chicago Manual of Style, AP Style Guide,
or New York Time Manual of Stye and Usage.

If it is any solace to you, the AP Stlybook and Chicago Manual of Style
both agree with you against the NY Times. Chicago waffles a tiny bit,
however, saying that if the plural form is confusing without the apostrophe,
then use it.

Did you look up the definition of "word"? How is "DME" a "word"? As Ron
implies, "VOR" *could* be considered a "word", but the vast majority of us
spell it out and don't consider it to be a "word".

Then what do you think it is? It's not an abbreviation and you apparently don't
think it's an acronym. So, what is it?

The latter being a quick read on eye infections.

They *are* both abbreviations. "DME" is a shortened form of the phrase
"Distance Measuring Equipment", while "VOR" is a shortened form of the
phrase "Very High Frequency Omnidirectional Range".

I'll have to correct every acronym list I've worked with... wait, the odds of
the military changing are pretty low.

Did you see the latest AOPA rag? It uses the term "initialism" for DME
and VOR etc. That's even worse then our disagreement over the term
acronym and abbreviation.

What's your point? That the military also misuses the word "acronym"? Are
we supposed to be surprised about that?

Why? "Initialism" is a perfectly valid word and does describe both "DME"
and "VOR". Perhaps when you go look up the word "word", you'll take the
moment to check out "initialism" as well.

I suppose my point is that never before I have heard/read/seen anyone
anywhere complain that DME and VOR, for example, are not acronyms.
But the next time someone supposedly misuses a word such as acronym,
it won't be the last.

Already looked up "word" - the definitions were not useful to the discussion.
"initalism" isn't in my dictionary.

Afraid I missed that thread -- but just noticed that my electronic
American Heritage gives "WAC/Women's Army Corps" as an example of an
acronym, and "USMC/United States Marine Corps" as an example of an
abbreviation, with no cross-referencing between them. Weird!

I can say WAC---wack , but I can't pronounce usmuck.

Not useful? Your dictionary uses the word "word" to define "acronym", and
yet you did not find the definition of "word" in that same dictionary to be
helpful in understanding the actual meaning of the word "acronym"? Or did
you mean by "not useful" simply that your dictionary's definition of "word"
didn't help support your incorrect understanding of "acronym"?

> "initalism" isn't in my dictionary.

I don't think "initalism" is a word. As far as "initialism" goes, here's
one dictionary's definition for you:

http://dictionary.reference.com/search?q=initialism

Hope that helps. You might want to think about getting a new dictionary.
