An instruction to the receiver that the transmission must be acknowledged.
Reference all of a transmission after the word or phrase given.
What you have transmitted is correct.
I have made an error and the correct information follows.
Numerals or numbers follow.
The next word will be spelled out phonetically.
This is the end of the transmission, no reply is expected.
This is the end of my transmission at this time, your reply is necessary.
I have received your transmission satisfactorily.
Repeat the last transmission.
This transmission is from the station whose call sign immediately follows.
That which immediately follows is the date-time group of the message.
I must pause for a few seconds.
I must pause longer than a few seconds and will recontact you by call sign.
I have received your signal, understand it, and will comply. Since the meaning of
ROGER is included in that of WILCO, the two prowords are never used together.
Your last transmission is incorrect; the correct version follows.
unparen ( ) ), slant ( / ), quote or unquote ( " ), hyphen (-
in a hyphenated word), colon (:), semicolon (;), and
dash (-) when used between numbers or letters and
numbers. Numbers are always pronounced as follows:
ZE-ro, Wun, Too, Tree, FOW-er, Fife, Six, SEV-en,
Ait, and NIN-er. Letters are always pronounced, when
spelling out a word, by using the ICAO international
phonetic alphabet (AL-fah, BRAH-VOH, CHAR-lee,
etc.). You studied the international phonetic alphabet in
the Basic Military Requirements training manual, and a
copy is provided on the first or second page of each
DOD FLIP IFR Supplement.
therefore classified, the PMSV operator must have
access to the ships latest observations and TAFs.
The ships TAF, by itself, is usually not classified
since it does not provide the ships position. Weather
observers, even in nonsecure work areas, may obtain
and keep a sanitized copy of the ships observation and
forecast handy for ready reference. A sanitized copy
means that the ships name, all references to locations,
and message routing indicators have been deleted.
When passing U.S. Navy ship weather updates to
aircraft via PMSV, do not mention the ships position or

naval ships operating off the coast commonly call via
PMSV for updates on the latest observation and forecast
for "USS SHIP." Since relating the name of a U.S. naval
ship to its location, or even the fact that a certain ship is
operating in the area is usually classified, the pilot may
not ask for the weather for the ship by name. It is
essential that military observers or, at least, the duty
forecaster keep informed of the naval ships operating
within their area of responsibility (AOR). Additionally,
although the weather observations from the ships
contain the ships location and identification, and are
the name of the ship. Also, do not discuss expected
arrival time of the aircraft at the ship, since this would
give hostile forces a good estimate of the ships distance
from shore. Rest assured, the pilot can find the ship and
knows within minutes when his aircraft will be arriving.
You may have to read an entire TAF forecast over the
radio to prevent giving away the flight duration.
In addition to the communication systems we have
just discussed, several communications systems or
subsystems are designed especially for shipboard or
mobile operations. Some of the systems are intended
primarily for environmental communications, while
