What is the main purpose of a supplemental manual?

The main purpose of a supplemental manual is to provide specific information not included in the original publication. Supplemental manuals are designed to complement the existing documentation by offering additional insights, updated procedures, or clarifications that are often necessary when technical or operational changes occur in a system or equipment.

While the primary manual includes essential information, it may not cover every scenario or provide all the latest details due to its original scope. Therefore, the supplemental manual serves an important role in ensuring that users have access to comprehensive and relevant information without overhauling the entire original manual. This approach allows maintenance and operational teams to have the most current and applicable instructions readily available, which might not be feasible to include in the original documentation without making the manual overly lengthy or complicated.
