ASD-STE100 (Simplified Technical English or STE, for short) is a controlled language for the preparation of technical documentation.
English is the international language of science, technology and human relations. It is also the language of the aerospace and defense industry. However, it is not often the native language of the readers of technical documentation. Many readers have a limited knowledge of English. Complex sentence structure and the large number of meanings and synonyms that many English words have can cause confusion.
STE was created in the late 1970s by the Association of European Airlines and the European Association of Aerospace Industries, in cooperation with the Aerospace Industries Association of America. The goal was to make aircraft maintenance documentation more readable for those with limited knowledge of English. The resulting AECMA Simplified English Guide was released in 1986 and later became the ASD Simplified Technical English Specification, ASD-STE100.
Today, the success of STE is such that other industries use it beyond its original intended purpose of aerospace maintenance documentation. Interest in STE has also increased dramatically in the areas of language services, professional translation and interpreting, as well as in the academic world.
Issue 8 of the specification fully replaces all previous issues and revisions.
