The S-Series of ILS specifications
S1000D does not stand alone. It is one member of the S-Series, a suite of specifications that together cover Integrated Product Support (IPS) — the engineering, logistics, and information activities that keep a product working through its life.
Each S-Series specification handles one IPS discipline. They share common terms and processes, so data produced under one specification can feed another. S1000D is the technical-publications member of the family.
The family name uses ILS (Integrated Logistics Support), the traditional term. The specifications now describe themselves with the broader term IPS (Integrated Product Support). The two names refer to the same suite. SX000i is the umbrella guide that links the members.
The family at a glance
The table below lists each specification with its official scope. SX000i is the guide; S1000D through S6000T are the working specifications.
| Specification | Scope |
|---|---|
| SX000i | International specification for Integrated Product Support (IPS) — the umbrella specification that guides the use of the rest of the S-Series |
| 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 |
ASD-STE100 Simplified Technical English (STE) is not part of the S-Series, but it is closely associated. STE is a controlled-language standard. It defines a limited set of writing rules and approved words so that maintenance text is clear and easy to read, including for people who do not speak English as a first language. S1000D authors often write content in STE. See Simplified Technical English for detail.
How the members fit together
The specifications cover different stages of a product's support story:
- SX000i explains how to use the rest of the suite together, so the members stay compatible.
- S3000L analyses what support the product needs (LSA), early in the life cycle.
- S4000P plans the preventive maintenance — the scheduled tasks and their intervals.
- S1000D produces the technical publications that tell people how to operate and maintain the product.
- S2000M manages the material — the spare parts and provisioning.
- S6000T analyses and designs the training.
- S5000F feeds real in-service data back from the field, so the earlier analyses can improve.
A single program can use several S-Series specifications at once. Shared definitions let the analysis from S3000L and S4000P drive the content that S1000D authors write, and let S5000F return field data that refines both. The members are designed to exchange information, not to work in isolation.
Who manages the S-Series
The S-Series is a joint international effort. It is managed by multinational teams from two industry associations:
- ASD — the AeroSpace and Defence Industries Association of Europe.
- AIA — the US Aerospace Industries Association.
The suite grew out of work first done under AECMA, the European aerospace manufacturers' association that later became ASD.
S1000D has one extra governing partner. Because it deals with technical publications shared across civil aviation, it is managed by ASD, AIA, and the ATA e-Business Program (Air Transport Association / A4A) through the S1000D Steering Committee. The other S-Series members are managed jointly by ASD and AIA.
| Specification | Managing organizations |
|---|---|
| S1000D | ASD + AIA + ATA (A4A) |
| SX000i, S2000M, S3000L, S4000P, S5000F, S6000T | ASD + AIA |
The specifications are published as open standards and can be downloaded for free from the official sites.
Programs pick the members they need. A defense aircraft program, for example, might run S3000L for its support analysis, S4000P for maintenance planning, and S1000D for its technical manuals, all under the guidance of SX000i. This combination is illustrative — each program defines its own scope.
