Quick answer: Aerospace Tech Pub is not one job. A Technical Author writes maintenance procedures. A Technical Illustrator builds the drawings. An IPC or CMM Author specialises in one type of manual. An STE Checker reviews the language. If you like reading engineering data and writing step by step, start with Technical Author. If you think in pictures, look at illustration. Most freshers begin as an author and branch out later.
You have heard “Tech Pub” a hundred times by now. Maybe from a senior, maybe from a job portal.
But when you open the listings, the titles are all different. Technical Author. Technical Illustrator. IPC Author. CMM Author. STE Linguistic Checker. Technical Data Engineer.
Are they all the same job? Not really. Here is a plain guide to what each role does, so you can pick a direction before you apply.
The big picture: what the team produces
An aerospace Tech Pub team turns raw engineering data into the manuals that technicians use on the hangar floor. That includes procedures to remove and install parts, parts lists with pictures, wiring diagrams and repair instructions. Several people with different skills work on each manual.
Technical Author
The Technical Author is the entry point for most freshers.
- What you do: read engineering drawings, service bulletins and change documents, then write clear step-by-step maintenance procedures.
- Tools you use: authoring tools such as Arbortext Editor.
- Standards you follow: ATA 100, iSpec 2200 or S1000D, and ASD-STE100 for the language.
- Who it suits: people who like detail, reading data and writing precisely.

Technical Illustrator
- What you do: create and update the drawings that sit inside manuals, such as exploded views and step-by-step graphics.
- Tools you use: illustration tools such as IsoDraw and similar software.
- Who it suits: people who think visually and are comfortable with 2D and 3D engineering drawings.
A good illustrator makes a manual faster to use, because the technician can see the part instead of imagining it.
IPC Author (Illustrated Parts Catalogue)
- What you do: build and maintain the parts catalogue, which lists every part with its number, description and position in the assembly.
- What it needs: comfort with bills of material and parts data.
- Who it suits: people who enjoy structure, data and accuracy.
CMM Author (Component Maintenance Manual)
- What you do: write the manuals for repairing and overhauling individual components, such as a pump or a valve, rather than the whole aircraft.
- Who it suits: people who like going deep into one system.
CMM roles often ask for a few years of experience, so many authors move into them after their first role.
STE Linguistic Checker
- What you do: review manuals for compliance with Simplified Technical English, checking vocabulary, sentence length and clarity.
- Who it suits: people with a strong sense of language and an eye for small errors.

Technical Data Engineer or Proofreader
- What you do: check the technical content for accuracy and consistency before it is released.
- Who it suits: people who like quality control and are happy to question every number.

What GLOINNT’s training covers
GLOINNT’s Aerospace Technical Publications Training is a 3-month classroom programme in Bengaluru, Monday to Friday, 9:00 AM to 6:00 PM. It covers the main manuals, AMM, CMM, AIPC, SRM, WDM, Engine Manual, ITEM and Service Bulletins, along with engineering drawings, Arbortext Editor for authoring and IsoDraw for illustration. Your manual is validated on a real aircraft, and the course ends with a written test and a B2 level English test.
It is open to BE/BTech graduates in Aeronautical or Aerospace Engineering, and AME (Mechanical or Avionics) candidates. We offer placement assistance in the aerospace domain, not a job guarantee. You can also look at current openings on our Careers page.
