Which TO file type is a new edition of the TO that supersedes the previous edition?

• A. TO Revision
• B. TO Supplement
• C. TO Change
• D. TO Update

Answer: (A)

In this context, the new edition that fully replaces the previous one is called a TO Revision. A Revision is issued to supersede the existing edition and becomes the current authoritative reference; the old edition is effectively canceled and replaced by the new one. You’ll typically see the word “Revision” on the front and a note indicating which prior edition it supersedes. The other types serve different roles: a TO Supplement adds extra information without replacing the main document, a TO Change documents specific updates to procedures between revisions, and a TO Update provides minor corrections or clarifications between revisions, without replacing the entire edition.
