ASD-STE100 Simplified Technical English (STE for short) is a controlled natural language and an international standard to write technical documentation. It is fully owned by ASD, Aerospace, Security and Defence Industries Association of Europe, Brussels, Belgium.
STE was developed in the late 1970s by the European Association of Aerospace Industries (AECMA, now ASD), with support from the Aerospace Industries Association of America (AIA), upon request from the European airlines (formerly, AEA). The goal was to make aircraft maintenance documentation easier to understand for readers with only a basic command of English. The resulting AECMA Simplified English Guide was released in 1986. In 2005, it became an international specification, and in 2025 it became an international standard: ASD-STE100 Simplified Technical English.
