ISO 1151-13:2026 is an ISO International Standard in the Flight dynamics - Vocabulary series. It defines the terms used for pilot training with technical equipment called flight simulators, and it covers the basic concepts used in science, engineering and manufacturing for flight simulation training devices for airplane and helicopter training. For readers, it is the common vocabulary for specifying, testing and discussing these devices consistently.
What does ISO 1151-13:2026 specify?
ISO 1151-13:2026 specifies the terms and definitions used for flight simulation training devices, with a focus on pilot training in a controlled environment. It gives the shared language for describing simulator categories, simulator features, validation data, and qualification-related testing.
The document is organized into Clause 1 Scope, Clause 2 Normative references, and Clause 3 Terms and definitions. Clause 3 is split into three parts:
- 3.1 Categories
- 3.2 FSTD’s simulation features
- 3.3 Basic definitions
An index at the end helps users find individual terms quickly.
What are the key requirements of ISO 1151-13:2026?
Because ISO 1151-13:2026 is a vocabulary standard, its main substance is the set of defined terms. In practice, those definitions shape how an FSTD is described, procured, evaluated and maintained.
Main device categories in Clause 3.1
| Term | Practical meaning |
|---|---|
| FSTD | The umbrella term for a flight simulation training device. |
| FFS | A full-size replica of a specific aircraft flight deck, with systems and cues needed for full ground and flight operations. |
| NWS | A device focused on navigation and weapon systems, with no motion cueing required. |
| FTD | A full-size replica of an aircraft cockpit or flight deck, without a required visual system, force cueing or motion cueing. |
| CPT | A procedure trainer with mission systems, without a required motion or visual system. |
| FNPT | A flight deck or cockpit environment used to represent aircraft flight operations to the extent that systems appear to function as in an aircraft. |
| BITD | A ground-based device representing the student pilot station of a class of aeroplanes. |
| CBT | Training software on a personal computer or workstation for self-training, without a cockpit replica. |
These distinctions matter because buyers, trainers and evaluators need to specify how much of the aircraft experience the device must reproduce.
Clause 3.2 defines the simulation features that can be described and assessed: cockpit layout and structure, flight model, ground handling, aircraft systems, flight controls and forces, sound cue, visual display cue, vibration cue, motion cue, navigation environment, weather environment, landing areas and terrain environment, and air traffic control environment. In practice, these are the elements that determine fidelity level and what must be modeled or reviewed for a given training task.
Clause 3.3 defines the evidence and test vocabulary used around qualification. Terms such as validation data, approved data, flight test data, validation flight test data, engineering simulation validation data, and validation data roadmap (VDR) describe where comparison data comes from and how it is organized.
The same clause also defines the main evaluation tools: qualification test guide (QTG), master qualification test guide (MQTG), statement of conformance (SOC), objective test, subjective test, validation test, functions test, integrated testing, footprint test, hands-off test, hands-on test, closed loop testing, driven test and manual testing. These terms matter because they describe how an FSTD is checked against aircraft data and how test results are documented.
Clause 3.3 also includes lifecycle terms such as FSTD operator, FSTD update, upgrade, convertible FSTD, correct trend and magnitude (CT&M), deadband, and transport delay. These help teams describe changes to a device and the performance effects that are observed during testing.
What terms does ISO 1151-13:2026 define?
- FSTD - Flight simulation training devices, the general category for the training equipment covered by the standard.
- FFS - A full flight simulator with a full-size replica of a specific aircraft flight deck and the systems needed for full operation.
- Validation data - Data used to prove that the FSTD performance corresponds to that of the aircraft.
- Approved data - Aircraft data collected using good engineering practice and accepted by the National Aviation Authority (NAA).
- QTG - The qualification test guide used as the primary reference for evaluating an FSTD.
- VDR - A validation data roadmap that identifies the best sources of data for the required qualification tests.
- SOC - A statement of conformance declaring that specific requirements have been met.
Who uses ISO 1151-13:2026?
ISO 1151-13:2026 is used by simulator manufacturers, aircraft manufacturers, flight training organizations, FSTD operators, evaluators, and National Aviation Authorities (NAA). They use it to specify simulator features, prepare validation data, write test guides, assess conformance, and maintain qualification for airplane and helicopter training devices.
What does the ISO 1151-13:2026 document contain?
ISO 1151-13:2026 contains a structured vocabulary for flight simulation training devices. It groups terms into device categories, simulation features, and basic definitions, and then provides an index for navigation.
The document covers the terms used in design discussions, validation work, qualification testing, and operational management of FSTD. It is especially useful when teams need to align on what a device can simulate, how it is tested, and what evidence supports its qualification.
The entries include terms for training device types, cueing and environment features, test methods, data sources, and documentation used in FSTD qualification and maintenance.
