Reference excerpt

The S-Series of ILS specifications is a common denominator for a set of specifications associated to different integrated logistics support aspects. Originally developed by AECMA (French acronym for the Association Européenne des Constructeurs de Matériel Aeronautique, later ASD), the S-Series suite of ILS specifications is managed currently jointly by multinational teams from the AeroSpace and Defence Industries Association of Europe (ASD) and Aerospace Industries Association (AIA) reporting to the AIA/ASD ILS Council. The ILS Council established the term S-Series (of) ILS specifications as the common denominator for all its specifications, and this term was consolidated with the publication of SX000i.

List of S-Series ILS specifications The specifications encompassing the S-Series of ILS specifications are as follows:

SX000i - International guide for the use of the S-Series of Integrated Product Support (IPS) specifications S1000D - International specification for technical publications using a common source database S2000M - International specification for material management S3000L - International specification for Logistics Support Analysis (LSA) S4000P - International specification for developing and continuously improving preventive maintenance S5000F - International specification for in-service data feedback S6000T - International specification for training analysis and design SX001G - Glossary for the S-Series of IPS specifications SX002D - Common data model for the S-Series IPS specifications SX003X - Interoperability matrix for the S-Series IPS specifications SX004G - Unified Modeling Language (UML) model readers guidance SX005G - S-Series ILS specifications XML schema implementation guidance S1000X - Input data specification for S1000D S2000X - Input data specification for S2000M S3000X - Input data specification for S3000L S4000X - Input data specification for S4000P S6000X - Input data specification for S6000T

Specification number encoding The encoding of the specifications is inspired by the Dewey Decimal Classification (DDC) of human knowledge. Transversal specifications are encoded with an "X" instead of a number, so as to represent the "10" used in Roman numerals. The initial "S" stands for specification, and the last letter indicates a keyword within the title, as highlighted in the list above. Exceptions to this rule are S1000D (where the "D" stands for documentation) and the specifications ending in "X", which represents "Exchange". Though all letters are upper case, SX000i has a lower case ending letter for improved readability and to prevent confusion with an "l" in certain fonts.

Other associated specifications Though strictly speaking it is not one of the S-Series specifications, ASD-STE100 is often associated to them because of its common origin with the S-Series of ILS specifications.

Integration of the specification and with other domains The S-Series of ILS specifications have in the past years made a significant effort to be interoperable, as this was not always necessarily true in the past. In that context, SX000i defines the common ILS process to which all the specifications will adhere, and SX002D defines a common data model that binds the data models of the different specifications together. This integration has ensured that the specifications have been included in the ASD Strategic Standardization Group (SSG) Radar Chart as adopted. In order to maintain the future interoperability of the specifications, SX000i establishes in its chapter 4 the governance of the S-Series ILS specifications and a common change process. A common unified S-Series ILS Specifications commenting tool was also established. The S-Series of ILS specifications are also involved in the development of the new ISO 10303-239 (AP239) PLCS Edition 3 project, so as to integrate with the ISO 10303 STEP architecture and non-support domains such as Engineering or Manufacturing. The representatives of the S-Series in the AP239 Edition 3 project are members of the Data Modeling and Exchange Working Group (DMEWG), which is responsible for the development of SX001G, SX002D, SX003X, SX004G and SX005G.

Worked examples

Example 1 — a first encounter with S-Series of ILS specifications

Start with the simplest possible case. Write down what S-Series of ILS specifications claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to S-Series of ILS specifications before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about S-Series of ILS specifications ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of S-Series of ILS specifications

In research: S-Series of ILS specifications appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses S-Series of ILS specifications in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: S-Series of ILS specifications is common in secondary-school and first-year university syllabi. It links to neighbouring topics Aerospace engineering, so understanding it makes those chapters shorter.
In everyday life: Look for S-Series of ILS specifications outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
