History:
The Q-code was originally instituted at the Radiotelegraph Convention held in
London, 1912. The Q-codes then grew over the years and decades.
The following list of current Q-codes is compiled from various sources.
The QAA...QNZ
series are reserved for the aeronautical service.
(ICAO Procedures for Air Navigation Services, Abbreviations and Codes
(PANS-ABC) [Doc8400])
The QOA...QQZ
series are reserved for the maritime services.
(ITU RR1990, Appendix 14)
The QRA...QUZ series
are for use by all services.
(ITU RR1990, Appendix 13, 14)
The QZA...QZZ
series for other usage.
ICAO PANS-ABC Doc8400 :
The ICAO Q Code
Editor's note: The following codes have been found in an
older editions of Doc8400 up to Doc8400-4 (4th edition 1989).
The Q-codes have been deleted and are no longer part of revised editions since
Doc8400-5 (5th edition 1999), so it is historical stuff now.
1. The meanings of the Aeronautical Code signals were
assigned by ICAO.
Since, in general, only stations of the Aeronautical Service will have
available copies of the Aeronautical Code it should not be used in
communications with stations of other services unless it is known that the
station concerned is familiar with the code.
2. Q signals may be amplified or completed by the addition
of appropriate location indicators, approved abbreviations, signals, call
signs, figures or numbers.
2.1. The information necessary to complete a signification, as indicated by a
blank space, shall be given except when:
(a) The blank spaces are enclosed within parentheses to indicate that their
completion is optional.
(b) an alternative meaning shown in parentheses is selected and the blank space
in this alternative meaning is completed.
2.2. The information used to complete the blank spaces shall be sent
immediately after the Q signal in the sequence shown in the signification.
2.3. Expressions or words in parentheses which do not include blank spaces have
the following significance:
(a) when following a blank space, the explanation of the information to be used
in filling in the preceding blank.
(b) when following a word or expression, an alternative to the word or
expression.
2.4. Q signals shall be read as a question when followed by a note of
interrogation signal (IMI). When a signal is used as a question and is followed
by additional or complementary information, the note of interrogation signal
shall follow this information.
2.5. Q signals that are capable of being given an affirmative or negative sense
shall be read in the appropriate sense when immediately followed by the signal
YES in the case of the affirmative or the signal NO in the case of the
negative.
2.6. Q signals used in the aeronautical service that are capable of being given
the sense of an order shall be read in this sense when immediately followed by
the signal ORD.
2.7. Q signals with numbered alternative significations shall be followed by
the appropriate figure to indicate the exact meaning intended. This figure
shall be sent immediately following the Q signal.
2.8. All times shall be given in Greenwich Mean Time (GMT) unless otherwise
indicated in the question or reply.
