Overview

ISO 1151-13: Flight dynamics - Vocabulary - Part 13: Training devices provides a comprehensive set of standardized terms and definitions utilized in the field of flight simulation training devices (FSTD). Published by the International Organization for Standardization (ISO), this standard ensures consistency in terminology for use in the design, qualification, regulatory, and training documentation associated with flight simulation. The document supports the harmonization of language in aerospace, making communication clear and effective among aircraft manufacturers, operators, authorities, and flight training organizations.

Key Topics

ISO 1151-13 focuses on critical aspects and terminology related to flight simulation training devices (FSTD), including:

• Categories of Training Devices: Defines different types of simulators such as Full Flight Simulator (FFS), Flight Training Device (FTD), Cockpit Procedure Trainer (CPT), Navigation & Weapon Systems Trainer (NWS), Flight and Navigation Procedures Trainer (FNPT), and Basic Instrument Training Device (BITD).
• Simulation Features: Covers features like cockpit layout, flight models, ground handling, aircraft and navigation systems, flight controls, sound cues, visual display, motion and vibration cues, weather and terrain modeling, and air traffic control environments.
• Testing and Evaluation: Outlines key terms related to FSTD testing and performance such as validation data, approved data, qualification test guides (QTG and MQTG), objective/subjective testing, footprint and functions tests, and fidelity levels.
• Operational Definitions: Includes important concepts such as transport delay, control sweep, continuous field of view, convertible FSTD, upgrades and updates, and the role of the FSTD operator.

Applications

This standard is vital in multiple industry contexts:

• Design and Documentation: Aerospace engineers and simulator manufacturers use ISO 1151-13 terminology to ensure product documentation is globally consistent and easily understood, facilitating smoother design cycles and compliance.
• Crew Training Organizations: Flight schools and commercial airline training centers apply this standard to improve communication and maintain alignment with international best practices, especially in pilot training programs using advanced flight simulation equipment.
• Regulatory and Qualification Processes: Civil aviation authorities and certifying agencies refer to these terms for drafting and interpreting requirements for FSTD qualification tests, certifications, and regulatory compliance.
• Operational Safety: The consistent use of standardized vocabulary enhances the clarity of procedures and training protocols, contributing to aviation safety and improved crew proficiency through realistic training scenarios.

Related Standards

ISO 1151-13 aligns with and complements several other key international standards in the field of flight simulation and aerospace terminology, such as:

• ISO 1151 Series: Other parts of the ISO 1151 standard covering additional flight dynamics vocabulary.
• ICAO Doc 9625: Manual of Criteria for the Qualification of Flight Simulation Training Devices, referenced in ISO 1151-13 for simulation feature criteria.
• ISO/IEC Standards: Various ISO and IEC standards covering technical definitions and requirements for simulation, avionics, and aircraft systems.
• National Aviation Authority (NAA) Requirements: Harmonizes with regulatory language for simulator qualification and operational approval worldwide.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through
ISO technical committees. Each member body interested in a subject for which a technical committee
has been established has the right to be represented on that committee. International organizations,
governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely
with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).
