Which elements are used to version documentation linked to engine configurations in ECMS?

• A. Archiving old documents
• B. Manual notes
• C. File names only
• D. By version numbers, revision levels, and linking to ECOs

Answer: (D)

In ECMS, documenting engine configurations is kept accurate and traceable by using formal versioning with version numbers, revision levels, and links to ECOs. The version numbers show major releases and compatibility, while revision levels capture smaller, incremental updates to the same version. Linking documents to Engineering Change Orders ties each change to a specific engineering action, creating a clear record of what changed, when, and why.

This combination ensures you can always identify which document applies to which configuration, understand the history of changes, and verify that the right documents accompany any given engine setup or modification. Archiving old documents, relying on manual notes, or using file names alone don’t provide this level of traceability or explicit change linkage, making them insufficient for robust configuration management.
