FOREWORD

1. Introduction

This document contains abbreviations and codes approved by the Council of ICAO for worldwide use in the international aeronautical telecommunication service and in aeronautical information documents, as appropriate, and uniform abbreviated phraseology for use in pre-flight information bulletins, with the status of Procedures for Air Navigation Services (in abbreviated form the PANS-ABC).

This document is the outgrowth of study by the Air Navigation Commission in consultation with States in the matter of controlling and coordinating abbreviations and codes. It brings together all abbreviations and codes for use in aircraft operations with the following exceptions:

a) Designators for Aircraft Operating Agencies, Aeronautical Authorities and Services promulgated in Doc 8585.

b) Data designators and geographical designators for meteorological bulletins given in the Manual of Aero- nautical Meteorological Practice (Doc 8896).

c) Aeronautical meteorological codes given in the Manual of Aeronautical Meteorological Practice.

d) Additional abbreviations for restricted use in aeronautical information services (AIS) documents given in the Aeronautical Information Services Manual (Doc 8 126).

e) Location Indicators given in Doc 79 1 O.

0 Aircraft Type Designators given in Doc 8643.

Table A shows the origin of each edition of the PANS- ABC issued since 1964 and subsequent amendments thereto, together with a list of the principal subjects involved, the dates on which the amendments were approved by the Council and the dates on which they became applicable.

2. Principles for formulation of abbreviations

The principles applied in the formulation of ICAO abbreviations are:

a) that allocation of more than one signification to a single abbreviation should be avoided except where it can be

reasonably determined that no instances of misinterpret- ation would arise;

b) that allocation of more than one abbreviation to the same signification should be avoided even though a different use is prescribed;

c) that abbreviations should make use of the root word or words and should be derived from words common to the working languages except that where it is impracticable to apply this principle to best advantage, the abbreviation should follow the English text;

d) that the use of a singular or plural form for the signification of an abbreviation should be selected on the basis of the more common use;

e) that an abbreviation may represent grammatical variants of the basic signification where such application can be made without risk of confusion and the desired grammatical form can be determined from the context of the message. ,

With respect to the latter principle, several variants are given for a number of abbreviations where it might not be obvious that the variant is appropriate or acceptable.

3. Specifications governing the use of abbreviations

Specifications governing the use of the abbreviations and codes are contained in the following ICAO Annexes and PANS:

a) use of abbreviations in the aeronautical information service: 3.6.4 of Annex 15;

b) use of the NOTAM Code: 5.2 of Annex 15;

c) use of abbreviations and codes in the international aeronautical telecommunications service: 3.7 of Annex 1 O, Volume Il;

d) use of abbreviations on aeronautical charts: 2.3.3 and 2.9 of Annex 4;

e) use of abbreviations in plain language meteorological messages: Chapters 3, 4, 6 and 7, Appendices I , 2 and 5 and Attachment A of Annex 3;

2511 1104



--`,,```,,,,````-`-`,,`,,`,`,,`---

(vi) ICAO Abbreviations and Codes (PANS-ABC)

f) use of abbreviations in air-reports: 4.12 of Chapter 4 and Appendix I of PANS-ATM (Doc 4444);

g) use of abbreviations and designators in flight plans and other air traffic service messages: Chapters 12 and 16 and Appendices 2 and 3 of PANS-ATM (Doc 4444).

4. Status

The Procedures for Air Navigation Services (PANS) do not have the same status as the Standards and Recommended Practices. While the latter are adopted by Council in pursuance of Article 37 of the Convention on International Civil Aviation, subject to the full procedure of Article 90, the PANS are approved by the Council and recommended to Contracting States for worldwide application.

5. Implementation

The implementation -of ICAO Standards, Recommended Practices and Procedures is the responsibility of Contracting States; they are applied in actual operations only after, and in so far as States have enforced them. However, with a view to facilitating their processing towards implementation by States, this document has been prepared in a manner which will permit direct use by operational personnel.

6. Notification of Differences

The PANS do not carry the status afforded to Standards adopted by the Council as Annexes to the Convention and, therefore, do not come within the obligation imposed by

Article 38 of the Convention to notify differences in the event of non-implementation.

The attention of States is, however, drawn to the provision in Annex 15 related to the publication in Aeronautical Information Publications of a list of abbreviations and their respective significations used by the State in its Aeronautical Information Publications and in the dissemination of aeronautical information. Differences from ICAO abbreviations or their significations should be identified.

7. Editorial Presentation

For encoding purposes the abbreviations given in this document are divided among a “general” and several specialized categories. For the convenience of the user, there is some duplication among these categories. Nevertheless, it may be necessary to draw on the “general” category of abbreviations when composing messages using one of the specialized categories.

Certain Q Code signals which through constant use have attained plain language status have been placed with their plain language significations in the portion of this document which contains the “general” category abbreviations.

Throughout the document, decode material is printed on white paper, encode material on green paper.

Any errors, omissions or discrepancies should be brought to the attention of the Secretary General of ICAO, 999 University Street, Montréal, Quebec, Canada H3C 5H7.

THE NOTAM CODE

PREFACE

(See 5.2.2 and Appendix 6 ofAnnex 15)

1. Introduction

The NOTAM Code is provided to enable the coding of information regarding the establishment, condition or change of radio aids, aerodromes and lighting facilities, dangers to aircraft, or search and rescue facilities. The NOTAM Code is a comprehensive description of information contained in NOTAM. It serves as an important criteria for storage and retrieval of information, as well as for deciding whether an item is of operational significance or not. It also establishes the relevance of the NOTAM to the various types of flight operations and determines whether it must therefore be part of a pre-flight information bulletin. In addition, it assists in specifying those items which are subject to immediate notification processes. The NOTAM Code also standardizes the presentation of the related plain-language text required at Item E) of the NOTAM Format as contained in Appendix 6 of Annex 15. Thus, the NOTAM Code is the basis for determination of the qualifiers TRAFFIC, PURPOSE and SCOPE used in Q . (Qualifiers) line and the related text to appear in Item E) of the NOTAM Format.

3.2 The second and ... ir1 letters identi the subject reported upon and the fourth and fifth letters denote its status of operation. The code identifying the subject or denoting its status of operation is, whenever possible, self-evident. Where more than one subject could be identified by the same self- evident code, the most important subject is chosen.

3.3 If the subject of the NOTAM is not listed in the NOTAM Code, inseri “XX” as the second and third letters.

3.4 If the condition of the subject is not listed in the NOTAM Code, inseri “XX” as the fourth and fifth letters.

3.5 When a NOTAM is issued containing a checklist of valid NOTAM, use KKKK as the second, third, fourth and fifth letters. When a NOTAM containing operationally significant infomation is issued in accordance with Appendix 4 and Chapter 6 of Annex 15 and when it is used to announce the existence of AiRAC AiP amendments or supplements (trigger NOTAM), insert ‘”IT’ as the fourth ‘and fifth letters.

Classificoton by subject (second and third letters) 2. Procedures

The transmission of NOTAM over the international aeronautical telecommunication service is governed by the appropriate sections of Annex 10, Volume II, and Annex 15. The former contains information on the acceptability of and priority to be accorded to NOTAM for transmission over the aeronautical fixed service (AFS), the latter full instructions on the textual format and contents of NOTAM.

3. Composition

General

3.1 All NOTAM Code groups contain a total of five (5) letters. The first letter of the code group is always the letter Q to indicate that it is a code abbreviation for use in the composition of NOTAM. The letter Q has been chosen to avoid conflict with any assigned radio call sign.

3.6 Facilities, services and other information which require coding have been classified by subject into sections and subsections. The second letter of the code group, which may be any letter of the alphabet except Q, indicates the subject subsections as follows:

AGA (Aerodromes)

ICAO abbreviations are to be used in preference to plain language wherever possible. In order to facilitate the dissemination of NOTAM by reducing the transmission time over telecommunication channels, eliminate translation and provide a suitable pre-flight information bulletin entry, the approved uniform abbreviated phraseology assigned to each signification of a two-letter combination in the NOTAM Code - Decode part is to be used in preference to significations wherever possible.

Note.- In addition, to meet certain requirements, a State may wish to provide a translation of the approved uniform phraseology in another language.

4. Significationsluniform abbreviated phraseology

The significationsiapproved uniform abbreviated phraseology assigned to NOTAM Code groups, as required for use in Item E) of the NOTAM Format (Annex 15, Appendix 6), are to be amplified or completed where necessary by the addition of

The information necessary to complete a significationhiform abbreviated phraseology, as indicated between parentheses, shall be given as applicable.

6. Amplification of significationsluniform abbreviated phraseology

The following is applicable to amplification of significationsluniform abbreviated phraseology:

amplifications relating to significations/uniform abbreviated phraseology of the second and third letters (subject of the NOTAM) must precede significationhiform abbreviated phraseology of the NOTAM Code;

amplifications relating to significations/uniform abbreviated phraseology of the fourth and fifth letters (status of operation) must follow significationhiform abbreviated phraseology of the NOTAM Code.

Examples (as applicable to Item E) of the NOTAM Format)

a) The touchdown zone lights of RWY 27 are not available due to power failure.

E) RWY 27 RTZL NOT AVBL DUE PWR FAILURE

b) The taxiway edge lights of taxiway B are obscured by snow.

7. Use of NOTAM Code groups

7.1 Five-letter NOTAM Code groups are to be used in conjunction with the NOTAM Format (Annex 15, 5.2.1, 5.3.2 and Appendix 6). They also constitute the basis for determination of the qualifiers Traffic, Purpose and Scope. Both NOTAM Code groups and NOTAM qualifiers are to be inserted in Q (Qualifiers) line of the NOTAM Format.

Note.- The most commonly used NOTAM Code groups and their respective relation with the qualifers Trafic, Purpose and Scope are presented in the NOTAM Selection Criteria tables (Doc 8126 - Aeronautical Information Services Manual, Attachment to Appendix C).

7.2 Five-letter NOTAM Code groups are formed in the following manner:

FIRST LETTER

The letter Q (see 3.1).

SECOND AND THIRD LETTERS

The appropriate combination of two letters selected from the “Second and Third Letters” section of the NOTAM Code to identify the facility, service or danger to aircraft being reported upon. (See 3.3,3.5 and 3.6.)

FOURTH AND FIFTH LETTERS

The appropriate combination of two letters selected from the “Fourth and Fifth Letters” section of the NOTAM Code

to denote the status of operation of the facility, service or danger to aircraft reported upon. (See 3.4,3.5 and 3.7.)

Examples

Note.- In the examples of NOTAM below, the letters Q to G inclusive, each followed by a closing parenthesis, identifl an item in the NOTAM Format. (Annex 15, Appendix 6).

a) The distance measuring equipment (DME), at Paris/Oriy, will not be available from the 31st day of March 1992 at 2359 UTC until the 1st day of April 1992 at 0600 UTC.

ICAO TECHNICAL PUBLICATIONS

The following summary gives the status, and also describes in general terms the contents of the various series of technical publications issued b y the International Civil Aviation Organization. It does not include specialized publications that do not fall specifically within one of the series, such as the Aeronautical Chart Catalogue or the Meteorological Tables for Intemational Air Navigation.

International Standards and Recommended Practices are adopted by the Council in accordance with Articles 54, 31 and 90 of the Convention on International Civil Aviation and are designated, for convenience, as Annexes to the Convention. The uniform application by Contracting States of the specifications contained in the Intemational Standards is recognized as necessary for the safety or regularity of international air navigation while the uniform application of the specifications in the Recommended Practices is regarded as desirable in the interest of safety, regularity or efficiency of international air navigation. Knowledge of any differences between the national regulations or practices of a State and those established by an International Standard is essential to the safety or regularity of intemational air navigation. In the event of non-compliance with an International Standard, a State has, in fact, an obligation, under Article 38 of the Convention, to notify the Council of any differences. Knowledge of differences from Recommended Practices may also be important for the safety of air navigation and, although the Convention does not impose any obligation with regard thereto, the Council has invited Contracting States to notify such differences in addition to those relating to International Standards.

Procedures for Air Navigation Services (PANS) are approved by the Council for worldwide application. They contain, for the most part, operating procedures regarded as not yet having attained a sufficient degree of

maturity for adoption as International Standards and Recommended Practices, as well as material of a more permanent character which is considered too detailed for incorporation in an Annex, or is susceptible to frequent amendment, for which the processes of the Convention would be too cumbersome.

Regional Supplementary Procedures (SUPPS) have a status similar to that of PANS in that they are approved by the Council, but only for application in the respective regions. They are prepared in consolidated form, since certain of the procedures apply to overlapping regions or are common to two or more regions.

The following publications are prepared by authority of the Secretary General in accordance with the principles and policies approved by the Council.

Technical Manuals provide guidance and information in amplification of the International Standards, Recommended Practices and PANS, the implementation of which they are designed to facilitate.

Air Navigation Plans detail requirements for facilities and services for international air navigation in the respective ICAO Air Navigation Regions. They are prepared on the authority of the Secretary General on the basis of recommendations of regional air navigation meetings and of the Council action thereon. The plans are amended periodically to reflect changes in requirements and in the status of implementation of the recommended facilities and services.

ICAO Circulars make available specialized information of interest to Contracting States. This includes studies on technical subjects.
