ASD-STE100 is a simplified technical vocabulary developed by the Aerospace, Security and Defence Industries Association of Europe (ASD) to write Component Maintenance Manuals (CMMs) for Air, Land, Sea and Space vehicles. The S1000D standard mandates STE documentation for NATO interoperability, terminology standardization and safety. Contact us to get a link to the ASD-STE100 Specification.
Click for STE Before and AfterThe ASD-STE100 vocabulary has a core of approximately 1,000 key words, including 208 verbs and Simplified Technical English grammar rules.
The MAXit Checker is an AI assistant that uses 19,000+ AI inferences to check text for ASD-STE100 compliance. The MAXit validation is done instantly during editing and shows curated suggestions.
Simplified Technical English (STE) is a global standard to write Component Maintenance Manuals (CMM)
mandated by the FAA, EASA and other regulatory agencies.
STE is part of iSpec ATA2200, S1000D and marked
LanguageISOCode="sx". STE is proven in 149 countries and at all airlines.
The MAXit Checker
instantly checks for STE compliance.
The Australian Defence Forces (ADF) mandate Simplified Technical English (STE) to ensure that all
technical content is clear, concise and easily understandable. This mandate is crucial for
mission-critical information where linguistic ambiguity can cause errors and compromise safety.
STE removes ambiguity, improves clarity and enhances readability.

NOTE: For ADF compliance, the MAXit Checker uses both the STE and Macquarie dictionaries.
SMART team members are experts in S1000D and understand the needs for Shipdex documentation. Simplified Technical English is ideal for multinational shipbuilding, design specifications, HSE safety and maintenance procedures. The MAXit Checker is compatible with the Shipdex.org Viewer.
The SMART MAXit Checker for Arbortext is used for documentation on the Northrop Grumman E-2D (US Navy) Command and Control aircraft. Our team also has experience with documentation for drones to support NATO interoperability. We offer convenient online STE writer training and writer certification.
The SMART aerospace team developed a Controlled English program from STE for the US Satellite Control Network (SCN-Colorado). The SATCOM dictionary was customized for LEO Satellite software, network operations, telemetry (TT&C), mission success and risk management. The Controlled English is a low-cost solution to prevent high-cost errors.

Our experts have many years of experience in Aerospace and Defense documentation specifications, including
S1000D, Shipdex, ATA2200, ASD-STE100, STANAG 4586, MIL-STD-40051E, DO-178C,
.xml, .dita, .sgml, IETM and ITAR compliance.
The SMART team offers services to convert MIL-STD-40051 to S1000D.
The curated dictionaries in the MAXit Checker are ideal to write Safety Management documents for eVTOLs, electrical propulsion systems, air navigation, flight operations and airline customer experience.
An audit version of theMAXit Checker uses AI rules to read and redact text for ITAR compliance. The
Sherlock version scans .xml documentation
and automatically redacts (hides) classified information.
If a convenience translation is permitted, computer-aided language translation tools can create accurate translations from the STE source text. The convenience translation version helps the global MRO workforce to solve the shortage of aviation technicians.
Simplified Technical English is ideal for Interactive Electronic Technical Manuals (IETMs) that are distributed electronically to global users.
