The Words This Industry Uses

Technical publications runs on acronyms, and most of them are defined nowhere a newcomer can reach. Each entry here says what the term expands to, what it actually means on a program, and what it gets confused with.

Grouped by where you meet them. Every entry links onward to the longer piece, because a definition is where a question starts rather than where it ends.

S1000D and S-Series

ACTApplicability Cross-reference Table

Business Rules

The decisions a program makes about everything its specification deliberately leaves open, from coding schemes to applicability to permitted content.

CSDBCommon Source Database

Data Module

The unit of content in S1000D: a self-contained piece of information, valid on its own, stored once in the CSDB and identified by a data module code.

DMCData Module Code

The structured identifier that gives every S1000D data module a unique address encoding what it covers and what kind of information it holds.

DMRLData Module Requirement List

The planned inventory of every data module a project intends to produce, functioning as both the scope baseline and the progress tracker.

Publication Module

The S1000D object that defines a deliverable publication as an ordered assembly of references to data modules, rather than as a document.

S3000LInternational procedure specification for Logistic Support Analysis

The S-Series specification for Logistic Support Analysis, the upstream process whose data drives publications, provisioning and training.

SNSStandard Numbering System

The breakdown that assigns every system and component on a product a number, forming the subject portion of every data module code.

The U.S. Army's government-furnished IETM authoring and viewing software, developed at Redstone Arsenal and specified across Army contracts.

IETMInteractive Electronic Technical Manual

A technical manual designed to be used on a screen, with navigation, search, applicability filtering and interactive behavior rather than pages.

IETPInteractive Electronic Technical Publication

The same category of deliverable as an IETM, under the name S1000D and several services prefer. Shaped per program by business rules.

ITARInternational Traffic in Arms Regulations

The U.S. regulations controlling defense articles and the technical data about them, whose definition of technical data reads like a tech pubs library.

MIL-STD-3031

The U.S. Army's S1000D business rules standard. Revision B is current and aligns to S1000D Issue 4.2 rather than the newest issue.

MIL-STD-3048

The U.S. Air Force's S1000D business rules standard for Technical Orders. Revision C is current and aligns to S1000D Issue 4.1.

MIL-STD-38784

The DoD standard practice for the general style and format of technical manuals, currently at Revision B, issued in 2020 and free from ASSIST.

MIL-STD-40051

The U.S. Army standard governing the content and structure of technical manuals, split into an IETM part and a page-based part, both at Revision D.

RPSTLRepair Parts and Special Tools List

The parts and tools listing in a U.S. military technical manual, identifying every replaceable item and the tools needed to work on it.

TDPTechnical Data Package

The complete technical description of an item sufficient to support procurement, production and sustainment, from drawings and models to specifications.

TMCRTechnical Manual Contract Requirements

The document that states exactly which technical manual standards a contract invokes and how each one is tailored for that program.

Civil Aviation

Airworthiness Directive

A mandatory instruction from a regulator addressing an unsafe condition, which removes the operator's discretion about whether to comply.

AMMAircraft Maintenance Manual

The airframer's manual for maintenance performed on the aircraft, covering fault isolation, removal, installation and scheduled tasks.

ATA Chapter

The numbering scheme that divides an aircraft into standard systems, so the same subject sits at the same number across manufacturers.

ATA iSpec 2200

The civil aviation information standard for maintenance documentation, organized by the ATA chapter numbering the industry has used for decades.

CMMComponent Maintenance Manual

The component vendor's manual for testing, repairing and overhauling a unit away from the aircraft, in a workshop.

EFBElectronic Flight Bag

The device, usually a tablet, that carries the flight operations library, charts and performance tools into the cockpit.

FCOMFlight Crew Operating Manual

The manufacturer's operating manual for the flight crew, describing systems, limitations and procedures for normal and non-normal operations.

IPCIllustrated Parts Catalog

The catalog identifying every replaceable part on a product and its relationship to the assembly, used to order the right item.

MELMinimum Equipment List

The list defining what may be inoperative and still permit dispatch, derived by each operator from the manufacturer's master list and approved.

QRHQuick Reference Handbook

The time-critical extract of abnormal and emergency checklists, condensed for use in the seat while the event is happening.

Markup and Content

CCMSComponent Content Management System

A system that manages content as components rather than documents, tracking each piece, its versions, its relationships and where it is used.

CGMComputer Graphics Metafile

The vector graphics standard technical illustration standardized on decades before SVG, still carrying hotspot data in aerospace libraries.

CMSContent Management System

A system for managing content as pages or documents, typically for a website, rather than as reusable components.

Content Model

The declared structure content must follow, expressed so a machine can enforce it, as opposed to a template that merely suggests a shape.

DAMDigital Asset Management

A system for storing and finding media assets such as images and video, optimized for retrieval and rights rather than document control.

Digital Thread

The connected chain of authoritative data across a product's life, from design through sustainment, with publications as its last mile.

DITADarwin Information Typing Architecture

An open XML architecture for topic-based technical content, built around typed topics, maps that assemble them, and specialization.

A system managing whole documents as controlled objects, with versions, approvals, permissions and an audit trail of who received what.

DTDDocument Type Definition

The older grammar mechanism declaring which elements and attributes a document may contain, inherited from SGML and still cited by contracts.

MBDModel-Based Definition
