Simplified Technical English

ASD-STE100 Simplified Technical English (STE) is a controlled natural language that is designed to simplify and clarify technical documentation. It was originally developed in the 1980s by the European Association of Aerospace Industries (AECMA) at the request of the European Airline industry, which wanted a standardized form of English for aircraft maintenance documentation that could be easily understood by non-native English-speakers.
