Winglet翼梢小翼
A winglet is an aerodynamic surface at the wingtip, usually vertical or angled upward, that reduces induced drag by altering the wingtip vortex and can improve fuel burn or climb performance on transport-category aircraft. In technical documentation, it appears in airframe descriptions, aerodynamic sections, performance manuals, illustrated parts catalogs, and modification or supplemental type certificate packages covering wingtip devices and their inspections.

Where this term appears
In translation, winglet appears in performance manuals, service bulletins, STC modifications, structural repair manuals, and maintenance task cards for wingtip inspections. Translators must preserve the difference between winglet, wing tip, raked wingtip, and wing fence, because these are distinct aerodynamic devices with different part numbers, maintenance actions, and allowable damage limits.
Translation checks
A frequent error is translating winglet simply as 'wing tip' or 'tip device,' erasing its specific function and inspection identity. This can cause confusion in parts catalogs where the winglet has a separate part number and maintenance criteria. Another mistake is using a decorative term like 'small wing' in engineering contexts, which lacks the required technical precision.
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.
