Outline of IETM

  • IETM or Interactive electronic Technical Manual, as the name indicates, it is a Manual which is interactive and in the form of electronic/digital.
  • Then PDF file is also electronic/digital, will that be called IETM?
  • Yes, undoubtedly PDF is also IETM. It's Level 2 IETM.
  • I need to give an example so that u can understand better about Levels. . Every one of us must have played digital games. In that, we need to cross various levels. The first level would be simple, the second little difficult, and 3rd level more challenging and 4th Level tough.
  • Question is, why this documentation is required?
  • Along with phone or vehicle or any household gadgets, we get a user manual because, in case we have any trouble while using, we can refer to the manual and resolve the issue, without connecting to OEM or service center as might not be available 24 X7.
  • Hence, these documents should be in simple language and easy to navigate, and easy to reach any point in few clicks.
  • The bigger the system/device the more pages are required and more variety of manuals are required. i.e. User manual, Operator manual, Maintainer manual, Spare list, and so on.
  • If some fault has occurred in the system, then the operator may need to refer to more than one manual and it is very difficult to refer to multiple hard copies. Even it is not easy to refer to multiple PDFs and refer to the issue as there is no linkage between all PDFs.
  • The purpose of the Manual is to guide the operator. If the manual is more dynamic that will be easy for the operator to refer and resolve the issue.
  • Level 4 and to some extent Level 3 will be very handy and very fast. All the documents are converted to a database, hence searching and inter-document referring will become easier.
  • I.e. a user can search for a problem and easily reach that particular page in seconds and also can see all the related topics to that topic which is being displayed.
  • Simple is Level 1 and advanced is Level -4
  • LEVEL -1 Normally scanned document Normal PDF file
    LEVEL -2 Basic PDF file with indexing, internal links between pages
    LEVEL -3 Intermediate HTML/XML based Software
    LEVEL -4 Advanced HTML/XML based software with advanced navigation features
  • Indian Defense wants all the equipment to be delivered along with IETMs since 2014.
  • Based on the complexity, Level 3 or Level 4 is asked in the RFQ document. Since 2018, mostly Level 4 is asked to deliver.

What is IETM is it a document similar to PDF?

  • IETM Level 1 and 2 are PDF files.
  • IETM Levels 3 and 4 are not any document like MS Word or PDF file.
  • IETM is a combination of Software and database. All the manuals are converted to SQL database. Using IETM Viewer, the user can access the data i.e. manuals, drawings, images, etc.
  • IETM has 3 modes. User mode where users can access the documents. Admin mode where Admin can create users and track the activities of users.
  • Super admin or Authoring tool, where all the manuals are converted to database using this authoring tool.


IETMs are available in 2 standards

  • INDIAN Defense Standard (JSG 0852:2001)
  • European Aviation standard (S1000D)


  • Government of India, Ministry of defense has framed few standards, Joint service Guide 0852:2001 and reframed in 2007.

European Aviation standard

  • It is called S1000D, mainly used in the Aviation industry
  • If the RFQ or tender documents say it is IETM means, it's Indian standard only. If the end-user wants S1000D, then specifically “S1000D IETM LEVEL -4” is mentioned.

What is the difference in both the standard?

  • Ultimately the purpose of both the standard is the same, easy accessibility to all the documents and key points in few clicks.
  • Indian Standard uses SQL Database and IETM Viewer to see the database. IETM Viewer has tools to navigate faster and most effectively.
  • IETM does not need any third-party software to run. OEM can edit using the authoring tool which is available in IETM software.
  • S1000d is very costly than the Indian standard.
  • Indian Standard is SQL based and HTML based and s1000d is XML based
  • Few companies convert Documents to XML and call them S1000D.
  • Simple XML is not an S1000D IETM. If the end-user /navy/shipowner does not have a CSDB studio then all these IETMs cannot be imported and made a single master IETM.
  • CSDB studio is very costly software and is mainly supplied by western counties. Indian version CSDBs is not compatible with original S1000d importing.

  • Technical Manuals / Technical Literature
  • Computer-based Training
  • Video film
  • Charts and Blowups
  • Training Work Models
  • Scale down models etc.

It is becoming very difficult to refer thousands of hard copies or PDF files when the issue arises in equipment to fix it.

Now from the past few years as per the guidelines received from Navy/Air force/ Army headquarters, they want OEMs to deliver IETMs along with actual machinery. IETM is one of the deliverables mentioned in the RFQ/Scope document. To submit the quote, you need to know the tentative cost of IETM.

If the system is small (we mean page count of all the manuals put together is not more than 4,000) IETM Level -3 is asked in RFQ or scope document.

If the page count is more IETM Level 4 is proposed.

Introduction to IETM | History of IETM | what is IETM?

  • Technical manuals (e.g. maintenance, user, training, operations, etc) published in electronic format are becoming more and more popular than paper based manuals for their interactivity, convenience and ease of use.
  • For example, the maintenance and operation manuals of a warship, which used to occupy 300 -350 sq. feet of prime area with thousands of pages of technical literature.
  • It was very difficult to refer some operating process or trouble shooting from thousands of hardcopies. Each time, maintainers had to refer multiple books to get information related to issues.
  • To address these issues, IETMs were introduced in ships initially. IETM is the replacement of paperwork / hard copies
  • IETMs are now replaced by their electronic versions occupying very little space and can be viewed on tablets from any part of the ship. These electronic technical manuals are termed as Interactive Electronic Technical Manuals (IETM) or Interactive Electronic Technical Publications (IETP).
  • Interactive Electronic Technical Manuals (IETMs) or Interactive Electronic Technical Publications (IETPs) are technical manuals (such as maintenance, training, user or operations manuals) usually authored in XML or HTML -5.
  • IETMs are a portable, electronic "library" which contain thousands of pages of documentation and images and allows end users to trace technical documentation in a more efficient manner, and the digital nature provides a more agile and accurate method of updating technical documentation.

The Classes of Electronic Technical Manuals

Level 0/Class 0 Non-Electronically-Indexed Page Images

As we all know that Level 0/Class 0 gives us the full description of the spectrum by providing the digital page with images that can be mean to plan for electronic archival filing. These pages allow the users to view only on an electronic device but it does not have the detailed index for navigation with this document for the online purpose.

Level 1/Class 1: Electronically Indexed Page Images

In this level systems with a digital page with images are provided with full page display and it allows the navigation by means of user-friendly which can be an automated index page. For e.g: Navy Advanced Technical Information System – ATIS). This type of systems which can be used in libraries and as well as used for reference setting for research and reading purpose.

Level 2/Class 2: Electronic Scrolling Documents

Systems for Interactive Display of ASCII-Encoded Documents using an intelligent index and Hypertext tags inserted into an attached document file. In general, the document is the result of a simple conversion from a page-oriented document but with little or no alternative by a subject matter expert with the exception of adding hypertext tags. These allow a user to navigate through the document, but have very limited, if any, author inserted navigation aids or a content-driven "NEXT" function.

Level 3/Class 3: Linear Structured IETMs

Interactive Display of Technical Information which is SGML tagged using MIL-D-87269 tags to the maximum extent possible and using a Hypertext presentation system for display in accordance with MIL-M-87268. It is based on a sequential SGML document file and not a hierarchically based on Database. Navigation is based on author developed make employing features such as to bring dialog boxes and content-driven logical "NEXT" function.

IETM Class-III is a linearly structured electronic document where the content is stored in smaller logical blocks of text with hyperlinked content to different logical pages and less use of scrolling compared to IETM Class-II. Class-III IETM is structured in freely flowing linear format following the logic of the content.

Key Feature of our Class-III IETM are:

  • Content derived from Logically Hyperlinked Static Pages and not related to database
  • Linear Structured Table of Contents with Hyperlinked data
  • Interaction through dialog boxes
  • Logical display of data in blocks related to content
  • Logical NEXT and BACK functions for User navigation through content
