A datalink is a digital communication link used to exchange data between an aircraft and ground stations, satellites, or other aircraft. In aviation and UAV documentation, the term appears in communication system descriptions, command and control interfaces, air traffic services, operational procedures, and security guidance to specify message formats, frequencies, lost-link behavior, and the distinction between datalink traffic and voice or payload video channels.
Translators encounter datalink in UAV command and control manuals, ground control station software, air traffic services messages, and remote identification documentation. It appears in lost-link procedures, signal strength indicators, and interface labels. Localization must keep technical terms such as uplink, downlink, and C2 link distinct, because mixing them can change the meaning of emergency procedures.
A common error is translating datalink as "数据链路" and then abbreviating it inconsistently, or merging it with "telemetry" when telemetry is only one data type carried by the link. Some translations also use "数据连接" in ways that sound like a physical connector. This can create confusion in lost-link checklists and system status displays where precise link state 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.
