It is shown, in particular, that the term "Risk Factor" appeared in the ICAO SMM due to the erroneous translation into Russian of the English term "Safety Risk", and its use in parallel with the term "Hazard" in high-level documents (the Air Code of the Russian Federation, article 24.1 and in the Decree of the Russian Federation Government from 18.11.2014 No 1215) introduces additional confusion at the level of air enterprises in the understanding of risk management within the technocratic concept of risk. . . . . .
