Center of Gravity重心

Center of Gravity is the point at which an aircraft would balance if it were suspended, representing the average location of all aircraft mass; the abbreviation CG is standard in technical materials. In aerospace documentation, it appears in weight-and-balance reports, loading manuals, flight test data, and operational limitation sections, where forward and aft CG limits are defined for safe handling and stability.

Where this term appears

Translators encounter CG in weight-and-balance manuals, load sheets, flight manuals, maintenance records, and UAV mission planning software. Strings such as 'CG envelope,' 'forward CG limit,' 'aft CG limit,' and 'CG position' must be handled carefully, and units or percent-of-mean-aerodynamic-chord values must remain consistent across tables and text.

The mistake that shows up most often

A common error is treating center of gravity as the balance point of the payload alone, rather than the whole aircraft. Another is rendering 'CG limits' as a single 'gravity limit,' obscuring the forward and aft range. Misreading these limits can shift the loading calculation and degrade controllability or stability.

Why consistent rendering matters

EASA and CE certification impose language requirements on maintenance and safety documentation. These terms carry airworthiness and liability implications, so they are rendered against the governing standard rather than translated freely.

Angel Translation locks terms like this into a project terminology base before expert review begins, so the same source term resolves to the same target term across every document in a submission — and stays consistent in the next revision. See the 8-step AI + expert workflow.
