The research aimed to study and experimentally verify the efficiency of the use of problem-based methods in teaching future air traffic controllers to conduct radio exchange in non-routine situations. The professional readiness to conduct radio exchange is viewed as a complex of professional skills and knowledge (communicative, cognitive and functional) enhanced by motivation. The study involved 67 university students of a bachelor's degree programme majoring in "Aviation transport". Tests, observations and specially designed questionnaires were used to evaluate the use of problem-based methods (role-playing, simulation of specific situations, problem-solving, case studies) in ESP study. The conclusion was made about the effectiveness of problem-based ESP methods since they simulate possible professional situations and promote communication between future air traffic controllers and pilots, thus contributing to the acquisition of professional knowledge and activation of use of standard phraseology of radio exchange and plain English in non-routine situations. As shown by the results of our study, problem-based ESP methods are effective in raising future air traffic controllers' motivation to acquire Aviation English as they bring the learning closer to professional life.

At the present stage of science and technology development the need to strengthen cyber security in every developed country and transform it into one of the most important

<p><span style="font-size: small;"><span style="font-family: Times New Roman;"><span>Nowadays solving practical problems in various sectors using intelligent solutions, based on expert systems are becoming more and more widespread. </span><span>In this paper an expert system method is proposed for assessment and prediction of destructive influences. All disadvantages of existing assessment systems are taken into account during the development and analysis phases. The most important estimated parameters are determined. This method is based on quantitative methods of expert evaluation, which gives the advantage: there is no need to collect large amounts of statistical data and clear formalization of the current situation.</span></span></span></p>
