ISO 5843-4:1990

Overview

ISO 5843-4:1990 - Aerospace - List of equivalent terms - Part 4: Flight dynamics is an international standard that provides a multilingual glossary of flight-dynamics terms. The document lists equivalent terms in English, French, Russian and German, with the English terms presented in alphabetical order. This second edition (1990) expands the original 1988 list and includes an annex linking term numbers to definitions in ISO 1151 (Flight dynamics - Concepts, quantities and symbols).

Key topics

• Multilingual flight dynamics terminology (English/French/Russian/German) presented as a list of equivalent terms.
• Alphabetical indexes for French, Russian and German entries to aid lookup.
• Cross-reference to formal definitions in ISO 1151 (Annex A), facilitating accurate interpretation of technical concepts.
• Examples of covered concepts (as shown in the source): aero-normalized derivatives, various forms of airspeed (indicated, calibrated, equivalent), types of altitude (geometric, geopotential, pressure, density, temperature), and many angles used in flight-path and aircraft attitude descriptions.

Practical applications

ISO 5843-4 is a practical resource for any activity that requires consistent multilingual use of flight-dynamics terms:

• Preparation of technical documents, manuals and specifications for international aerospace projects.
• Translation and localization of aerospace documentation, ensuring consistent terminology across languages.
• Regulatory and certification work where precise term equivalence is required between nations or authorities.
• Engineering communication across multinational design, test and operations teams to avoid misunderstandings in flight-dynamics concepts.
• Training materials and textbooks where standardised terminology improves clarity.

Who should use this standard

• Aerospace engineers and flight-dynamics specialists needing consistent term mapping.
• Technical writers, translators and documentation teams producing multilingual aerospace content.
• Regulatory bodies, certification agencies and standards committees coordinating international requirements.
• Aviation maintenance and operations personnel engaged in cross-border or multinational programs.

Related standards

• ISO 1151 - Flight dynamics: concepts, quantities and symbols (used as the definitional basis; Annex A of ISO 5843-4 provides correspondence).
• Other parts of the ISO 5843 series (multilingual lists for aerospace components and topics such as rivets, bolts and nuts, electrical equipment, environment/operating conditions, standard atmosphere, aircraft structure and more).

Using ISO 5843-4:1990 helps ensure consistent, authoritative aerospace terminology for flight dynamics across multiple languages, reducing ambiguity in international design, certification and documentation workflows.
