BVLOS超视距
BVLOS stands for beyond visual line of sight, a mode of unmanned aircraft operation in which the remote pilot cannot see the aircraft directly and instead relies on instrumentation, telemetry, or visual observers. In localized content, it appears in operational authorizations, safety risk assessments, detect-and-avoid procedures, and flight planning, where it must be distinguished from visual line of sight operations and other regulatory categories.

Where this term appears
BVLOS terminology appears when drone operators, manufacturers, or regulators localize operational manuals, specific operations risk assessments, mission plans, and training material. Translators encounter phrases such as 'beyond visual line of sight', 'extended visual line of sight', and 'visual observer', and must preserve operational roles and separation requirements without introducing local airspace-specific assumptions.
Translation checks
A common mistake is translating BVLOS as simply 'out of sight' or 'long-range', which loses the formal operational category and may confuse regulatory reviewers. Another error is merging visual observer or extended line of sight concepts into BVLOS, ignoring that these may have different approval, operational limitations, and detect-and-avoid requirements.
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.
