Maximum Takeoff Weight最大起飞重量
Maximum Takeoff Weight is the maximum total weight at which an aircraft is approved to begin takeoff, including the airframe, fuel or battery mass, payload, and crew or equipment. In aerospace documentation, it appears in type specifications, flight manuals, weight-and-balance records, loading schedules, and operational limitations where performance and structural boundaries are established, often with the abbreviation MTOW.

Where this term appears
Translators encounter this term in aircraft and UAV specification sheets, flight manuals, weight-and-balance calculations, loading software, and airworthiness compliance documents. They must keep the abbreviation MTOW or MGTOW aligned with the full term in tables, figure titles, and body text, and preserve units such as kg or lb without reordering values.
Translation checks
A frequent error is confusing maximum takeoff weight with maximum ramp weight or maximum landing weight, especially when all three appear in the same loading table. Another is translating 'approved' as 'recommended,' which weakens the limit. Such mistakes in weight-and-balance documents can lead to incorrect loading calculations and exceed takeoff or landing limits.
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.
