FOR THE STUDENT
The aim
English for Aircraft will help you use aeronautical manuals more easily It is designed for civilian or military technicians engineers and mechanics and can be used with a qualified teacher in a training course or for self-study It is for users of English with an intermediate level in written English
The first volume Documentation Handbook, contains the basic principles structure and vocabulary of aeronautical English, with a large number of authentic one-sentence examples from all aircraft systems
System Maintenance is a companion volume to the first It contains extensive texts and figures which are practical examples of the principles explained in the Documentation Handbook A cross-reference system (p 332) enables you to move from one volume to the other and consolidate your knowledge
How is the book organized?
System Maintenance is divided into twenty-four chapters, each one corresponding to a major ATA system (or group of systems in the case of the first and last chapters)
Every chapter begins with a checklist of basic terms and ends with a short glossary that provides a brief explanation of words of special interest or difficulty The main body of the chapter consists of a series of texts of various types accompanied by numerous illustrations
and activities The activities are technically-
based as well as linguistic, enabling you to explore both the technical content and the language used, and to acquire essential reading techniques

FOR TRAINING PURPOSES ONLY
You can check your answers to the exercises in the Exercise Key at the end of the book The Index gives you access to the terms explained in the glossaries at the end of each chapter
References in the margin to the Documentation
Handbook make it easy to find explanations of
the language, syntax and grammar used A wide range of texts
In System Maintenance, we have used
documents which reflect the range of styles and difficulty that a fitter, a mechanic, a technician or an engineer has to deal with today The texts are identified in such a way that it is very easy to select only the type of texts you actually need to
use,
The texts have been chosen to cover as wide a range as possible in the field of aircraft maintenance documentation You can choose the texts you want to study according to several variables :
- the ATA chapter;
- the type of document : AMM, SB, AD, TFU,
CMM, SRM, OIT, SIL, Technical Incident Reports, Technical Logs telexes and letters; - conventional (A300, A310) or glass cockpit
(A320) technology:
- conventional English (A300, A310) or
Simplified English (A320) Variety of language
The language varies in style and complexity The

* Note: Only the Aircraft and Component Maintenance Manuals are written consistently in Simplified English and
this only since 1986, Simplified English
Today, a relatively mature form of Simplified English is used in the Aircraft Maintenance Manuals and most Component Maintenance Manuals of aircraft such as the A320, Fokker
100 B747-400, B737-500, B767, A340, A330
and other aircraft of this generation
This means that the ground engineer on the shop floor working on these aircraft will be using job cards and reading system descriptions in
Simplified English However, this is not always
the case when working on planes produced prior to 1986 Therefore, even people working on the basic documentation will be faced with both Sim- plified and conventional English for some time This is all the more true for Engineering Departments where virtually none of the “day- to-day” documentation issued -by the vendors
and manufacturers is in Simplified English Consequently, English for Aircraft is not a Simplified English manual: we have taken both forms of the language into account A short account of Simplified English is given on pages 195-202 of the Documentation Handbook The activities
There are three basic categories of activity, identified by one, two or three stars:
* rapid “scanning” or “skimming” activities to improve the speed, accuracy and efficiency of your reading
** linguistic activities to practise the syntax, grammar or vocabulary used in the documents **%*% comprehension activities to check your understanding and your ability to use the technical content of the documents
Trang 7Points to remember
It is important, at least initially to approach the texts only through the activities Do not try to translate word for word or understand everything in the texts
Most of the modules of texts and exercises should only require about 20 minutes’ work This means that it is easy to work regularly and
frequently
FOR THE TEACHER The learning process
System Maintenance has been designed to
provide a reservoir of texts of convenient length enabling the student or the teacher to go back
and forth between explanations and examples in the first volume and application in the second This pendular movement consolidates the
learning process
The variety of systems types of document and
types of activity make it easy to choose course material according to the language ability,
technical background and professional ability of
the students
Every teacher will naturally draw on his or her
personal experience and skill to adapt these materials to the needs and abilities of each group Most of the exercises can be used successfully in the form of pair work group research, competitive team activities,
information exchange, etc
The aim of all the activities is to lead the student
gradually to acquire the various facets of an effective reading technique In no case do the activities represent an exhaustive treatment of a
text; it is always possible to go further Returning to a text that has already been covered is highly profitable
FOR TRAINING PURPOSES ONLY
Reading techniques
The activities reflect the different skills or
knowledge necessary to read and use a technical document They include:
- vocabulary acquisition and expansion;
— recognition of verb forms, word endings, prefixes compound words, etc
~ recognition of the significance of the above as
regards their differences in functional and not just grammatical terms:
— a knowledge of basic English sentence
structure (syntax);
— the ability to use the context to understand unknown words;
— the use of titles, headings tables and figures with relation to a text:
- the ability to find information quickly:
knowing where to look and what to look for:
— the ability to find the key words and the main
verb in a sentence:
- immediate recognition of the type of
information contained in a document or a sentence (e.g instruction description operation, location, purpose means cause conse-
quences ):
- the use of prior technical knowledge to
interpret a text:
— the ability to follow a logical thought process
in English and to visualize meaning, thereby reducing translation to a minimum;
— the creation of a “checklist” of points which should develop into an automatic reflex for tackling any document

On in-service aircraft, cracks, caused by vibration, have been discovered on
refrigeration unit intermediate ducts
To remedy this condition, improved intermediate ducts (addition of three additional riveted stiffeners) have been installed on aircraft MSNO37 thru 052
on production line
As this solution proved to be an unsatisfactory improvement, it is recommended to replace existing intermediate ducts by reinforced ducts (with all stiffeners completely riveted)
This new technical status has been incorporated on production aircraft

To improve conditioning airflow regulation in flight compartment
When both packs are operating, some flight crews find that airflow is too
high
This Service Bulletin proposes addition of a manual control electric valve on air supply duct to permit variation of airflow in flight compartment
according to flight crew \requirements
In order to alleviate the jinconvenience resulting from excessively long lead
time for availability of Service Bulletin 21033 kits, a particular scheme has
been implemented This)scheme calls for reduced air flow in the cockpit in
compliance with Mod 1620 requirements
This Service Bulletin covers this particular scheme

B Air-Cycle Machine (Ref Fig 004)
The main component of the air-cycle machine is a rotating shaft A turbine, a compressor and a fan are mounted along the shaft The shaft rotates on two self-acting foil-air bearings, a double self-acting air- thrust bearing takes the axial thrust loads Air tapped from the turbine inlet, is used to cool the bearing and then discharged into the ram airflow Labyrinth seals reduce air leakage between static and rotating parts The light-alloy turbine is supplied with air through a stainless-steel nozzle and a light-alloy scroll In case of turbine break up, the stainless-steel nozzle acts as a containment ring The light-alloy centrifugal compressor is mounted in
the center of the rotating shaft Air is supplied from a light-alloy scroll An
outer scroll has a stainless-steel diffuser In case of a compressor break up, the stainless-steel diffuser acts as a containment ring Fan air is discharged through a conical nozzle, this gives a jet-pump effect in the fiberglass plenum diffuser The primary heat exchanger outlet is connected to the discharge ram airflow through the fiberglass diffuser
