Abstract: The nonstandard translation of civil aviation terminology not only exists in manuals and technical documentation used by airlines, but also in professional civil aviation reference books and other civil aviation related reference books. On the premise of translation accuracy, civil aviation terminology can be translated based on the transparent principle. Literal translation, sequential translation and zero translation can be used to keep the morphological formation and meaning of the original terminology. In this way, the meaning of the terminology can be understood from the translation. And back translation can also be used to verify the accuracy of civil aviation terminology translation.
