Master Minimum Equipment List主最低设备清单
The Master Minimum Equipment List is a regulatory baseline document that identifies the equipment and systems that may be inoperative while an aircraft is still permitted to operate, subject to conditions. In aerospace localization it appears in airline operations manuals, dispatch documentation, and type certification material, often abbreviated as MMEL and used as the source from which an operator’s MEL is developed.

Where this term appears
Translators encounter MMEL in operations manuals, dispatch reliability guidance, and regulatory submissions. The content is highly structured, with columns for repair intervals, number installed, number required, and operational restrictions, so localization must preserve cross-reference links. In multilingual airline documentation, even small changes to condition phrases can affect whether a flight may be dispatched with equipment inoperative.
Translation checks
A frequent error is translating “may be inoperative” as “must be repaired” or “is unserviceable,” which reverses the dispatch permission logic. Another is formatting the list as narrative text and losing the column relationships among repair intervals, quantities, and limitations; this can make it impossible to apply the correct relief condition and can lead to invalid dispatch decisions.
Keep the term aligned across your files
Check procedure sequence, part names, limits and cautions against the supplied references. Applicable aviation or market requirements depend on the product and project pathway.
Provide approved terms and previous translations with the source files. Agree how variants, ambiguous wording and revisions will be reviewed. Terminology maintenance and any termbase handback are confirmed in the project scope. See the 8-step AI + expert workflow.
