Аbstract. This article is devoted to the consideration of airport aviation security as a complex
function. The article uses the analysis of advantages and disadvantages, as well as the method of
formalization. Using two methods, a multi-criteria task was formulated, which serves as the basis for
building an airport security system based on key indicators. At the same time, the main aspects
reflecting the most important points in the distribution of the significance of the criteria by their
weight coefficients were noted.
Keywords: aviation security, security formalization, quantitative safety indicators, procedural
