Another objective was to provide designers a means of facilitating their job while respecting the stringent safety criteria. This project was divided into three parts conducted in the frame of R&D activities, the first one dealing with the terminological aspects, the second devoted to syntax and the third one focused on the acronyms for computers naming. Throughout this innovative linguistic project, Airbus proves to be aware of the constant need to enhance safety. Keywords: Controlled language – Word order structuring – Terminological standardization – Abbreviations – Procedural texts – Acronyms. ___________________________________________________________________________ Introduction : what is a CL ? Controlled languages (CLs) are of vital interest (for safety and economic reasons, etc.) for industry. Indeed, they have been created in order to resolve problems of readability (reducing the complexity of syntactic structures of a text increases its readability), of comprehensibility (a lexical disambiguation increases the comprehensibility of a text) and of translatability (a syntactic and semantic control facilitates the shift between two languages) but not of grammaticality (a grammatical text written in a given CL will not necessarily be considered as grammatical in the corresponding natural language). As Goyvaerts (1996) wrote, “Industry does not need Shakespeare or Chaucer, industry needs clear, concise communicative writing - in one word Controlled Language”. “A restricted or controlled language refers to a system that limits language to a set number of core vocabulary words, and usually, a set of writing guidelines for grammar, mechanics, and style. […] A controlled language attempts to reduce ambiguities, colloquialisms, and synonyms” (AECMA (1995)). English is a very productive natural language for CLs’ creation as it is the current international language used for trade and science. Nevertheless, other natural languages such as German, Chinese, Swedish, French, etc. have generated CLs. A CL is not “simple” or “baby” English, German, French, etc. but simplified English, German, French, etc. The Airbus project In aeronautics, pilots must daily use procedures in any type of situations (normal or abnormal). It was observed that some incidents aboard commercial planes were due to the non compliance with procedures. Whether it be oral or written, a message will be considered successful and effective when it is in keeping with the mental process implemented to reconstruct and interpret the information contained in this message. But, because one does not expect any individual to master and speak a number of languages with the same level of competence as the one he has reached in his own mother tongue, industry prefers a precise and concise language to the use of a natural language which would allow non- parallel grammatical constructions, possessing inherent ambiguities of various types, etc. In 1998, Airbus started a project dedicated to the creation of a controlled language for industrial use; in …
