THE NEWEST DICTIONARY OF AIRBUS ABBREVIATIONS AND ACRONYMS FROM AIRBUSWORLD, GOOD MATERIAL FOR UNDERSTANDING THE ABBREVIATIONS AND ACRONYMS WHILE STUDYING ABOUT AIRBUS PLANES…

Airbus abbreviations and acronymsDearportal user, The aeronautical industry has beenusing abbreviations and acronyms for along time! We have designed the abbreviation and acronym list belowto help youfind the meaningof such series of letters!The abbreviations and acronyms are extracted from‘Lexinet’, our Airbus terminology reference tool.It also contains the vocabulary inuse at Airbusand provides definitions of terms. Abbreviations and acronyms are listed with a status in the 3rd column:. The “Approved” onescan be used in alldocuments and data relatedto Airbus programs without restrictions.. The “For information” ones may be found inthe Airbus environment, butthey shall not be used inDefinition Dossiers or technical publications. Tofind the meaningof a specific abbreviation or acronym, just presstogether the ‘Ctrl’and ‘F’ keyson your PC keyboard andfill out the small box atthe top. Then press enteruntil you get the abbreviationin the left column: Youwill then find the full form ofthe abbreviation in the centre column.
