Introduction
1.1
Purpose
Module 2
The purpose of this module is:
•
to provide a list of those abbreviations which are approved for general use
(Appendix A) by The Company,
•
to record those abbreviations which are specific to power plant and APU
manufacturers (Appendix B) and for which The Company has no control,
•
to record those abbreviations that are necessary but that cannot, because of
severe space limitations on the aircraft or for other exceptional circumstances,
comply with the rules governing abbreviations (Appendix C),
•
to provide rules for the proposal, approval and incorporation of new
abbreviations.
1.2
The Company - General Policy
The Company accepts that the use of abbreviations will always be necessary. However,
such usage must be strictly controlled because the indiscriminate use of abbreviations
can lead to the formation of a separate "language" which is not generally
understandable.
The Company is committed to a policy of Cross Crew Qualification (CCQ) between
Aircraft Programs and Projects. Special attention shall be paid to the need to be
absolutely consistent in the use of abbreviations and this consistency must apply across
all aircraft projects.
The use of abbreviations shall be restricted to:
•
abbreviations to be used only in connection with power plant and APU,
•
abbreviations to be used only in connection with circuit breaker panels and
screen/display messages.
It is to be used in all cases where abbreviations are necessary in communications
between departments and with suppliers.

Module 2
Definition
Abbreviation:
A shortened form of a written word or phrase used for brevity in place of the whole word
or phrase. It is commonly made by the omission of letters from one or more parts of the
whole word or phrase.
•
Ref: AP2080 Module 1 - Glossary of Approved Airbus Terms and Expressions
(GATE)
1.4
Types of Abbreviation
Based upon ISO 704 (Principles and methods of Terminology), there are basically three
types of abbreviation:
•
Abbreviation: Created by omitting part(s) of the term
e.g.: Cockpit: CKPT.
•
Initialism: Created by using the first letter of each term element to form a
designation. Alternatively, the sound of an element may be used. In some
cases they can be pronounced like a word,
e.g.: Abbreviated Test Language for Avionics Systems: ATLAS.
•
Acronym: Formed from other terms by the process of clipping and blending,
e.g.: Aviation Electronics: AVIONICS.

Module 2
Approved Abbreviations
Abbreviations approved for use, by The Company are listed in the Appendices of this
module of the AP.
5.4
Control of Abbreviations
It is essential that the unnecessary proliferation of abbreviations shall be prevented.
5.5
Abbreviations Excluded from this Module of the AP
The following types of abbreviations are not included in this module of AP2080:
•
those which are specific to a given discipline,
•
units of Measurement and Associated Symbols which are given in ABD0046 Units of Measurement,
•
abbreviations specific to EDP applications,
•
suppliers abbreviations used in their data and documentation unless approved
by the Airbus Reference Language Network,
•
abbreviations related to development activities which are not yet formalized
unless approved by the Airbus Reference Language Network.
5.6
New Abbreviations
If a new abbreviation is required this shall be discussed with the local Airbus Reference
Language Network Representative (see page 111 of this Module).
When an abbreviation is submitted for approval, the Airbus Reference Language
Network Representative must:
•
ensure that the abbreviation is necessary and can be justified, and
•
consult the source documents listed in Chapter 3 - Reference Documents. If
an existing abbreviation is available this shall be submitted to the Airbus
Reference Language Network for approval and inclusion in this part of the AP.
If no existing suitable abbreviation is available, a new abbreviation may be formed in the
following manner:
•
remove the vowels from the right hand end of the term with the objective of
achieving a maximum length of eight letters,
•
if a length of eight letters cannot be achieved then remove the consonants
from the right hand end of the term.

5.6
Module 2
New Abbreviations, continued
The resulting abbreviation shall be submitted to the Airbus Reference Language
Network for approval provided that it is:
•
not more than eight letters in length and ideally not less than six letters in
length,
•
not ambiguous i.e. it shall be clearly related to the original term and NOT be
capable of mis-interpretation.
5.7
Abbreviations for Compound Terms
Where a term consists of two or more words, each word shall be abbreviated separately
in accordance with this module of the AP. Any existing approved abbreviation must be
used.
Eg: Power = PWR, Supply = SPLY therefore Power Supply abbreviates to PWR SPLY.
5.8
Multiple Meanings for Abbreviations
It is permissible for an abbreviation to have more than one meaning. In this case, the use
of the abbreviation must be carefully controlled to ensure that the required meaning is
clearly understandable from the text or drawing in which it is used. Multiple meanings
shall be avoided in the same or similar context.
5.9
Multiple Abbreviations for the Same Term
It is not permissible to have more than ONE abbreviation for the same term.
The only deviation from this rule is where exceptional limitations do not allow the
approved abbreviation to be used. Any deviation shall be approved by the Airbus
Reference Language Network.
5.10
Initialisms
Wherever possible the use of initials is to be avoided where general terms are
concerned. The preferred alternative is to use abbreviations for each word in accordance
with this part of the AP.
E.g.: for Ground Setting use GND SET and not GS.
(Note: This principle may not always be valid where the names of aircraft systems and
equipment are concerned).

5.11
Module 2
Procedure for Approval of New Abbreviations
Approval for use can only be given by the Airbus Reference Language Network.
Proposals for approval shall be made via the local Airbus Reference Language Network
representative (see page 111 of this Module) who will submit them to the Abbreviation
Data Base Administrator. Before submitting any proposal, this person shall check the
applicability of the request. The administrator will send out a consolidated proposal list
once a month. After acknowledging receipt of the proposals, the Airbus Reference
Language members shall review and either accept or reject the proposal. They may also
request further information or make constructive comments which will lead to the
creation of a satisfactory abbreviation.
All members shall respond to proposals within 20 working days. The absence of a
response within the specified period will be assumed to signify "no-objection".
The originating Airbus Reference Language Network member shall be responsible for
progressing and coordinating responses to his proposal to the stage where he can
present an agreed proposal for final ratification or the proposal cannot be justified and
must be withdrawn.
To ease the processing of the request, the layout and content of the request should
comply with the example form shown on page 15.
5.12
Listing of Approved Abbreviations and Associated Restrictions
Abbreviations approved for use within The Company are listed in this module of the AP.
Appendix A: All abbreviations can be used without restriction.
The following restrictions apply to Appendix B and Appendix C:
Appendix B: Abbreviations listed in this Appendix, which were originated by engine or
APU manufacturers, are approved for use in drawings, documentation, etc., directly
related to Power Plant and APU.
Note: Some abbreviations are specific to one particular manufacturer - as identified in

Module 2
Abbreviation Usage Conditions
Approved abbreviations may be used on drawings in accordance with The Company
policy. No indication of their meaning is required. When used in text, abbreviations
should always be preceded by the term in full on the first occasion of their use, as
specified in ATA Specification i2200.
Abbreviations may involve capital and/or small letters (upper/lower case) as defined.
Abbreviations used shall comply with AP2080 Module 2 unless covered by the
specified exclusions (ref. chapter 5).
Abbreviations can be used in the plural by the addition of a lower case "s" as follows:
•
Lower case text: "the two FCUs…".
•
Upper case text: "THE TWO FCUs…".
If it is not possible to use lower case text then "'S", eg: THE TWO FCU'S, may be used.
Abbreviations shall not be used in the possessive case.
Instead of writing: "the FCU's mounting", write: "the mounting of the FCU".
