Interactive Electronic Technical Manual (IETM) is a modern alternative to printed user manuals, training manuals, and operation and maintenance manuals used in the defense and aviation sectors. It provides an interactive and electronic medium that improves technical support, usability, and accessibility of complex systems. In contrast to static paper or PDF-based instruction manuals, IETMs offer defense operators and technical personnel an all-digital user guide solution with multimedia integration, interactive navigation, improved searching, and maintenance workflows. Interactive Electronic Technical Manual, in short, is called IETM. If you are a supplier of defence then along with the system/equipment you also need to provide training aids like CBT, Charts and blowup diagrams, Video films, Training work Modules and a few sets of Hard copies of the manuals and IETM.
