The paper refers to the evolution of methods, new technologies, and devices in security control processes in light of civil aviation requirements, procedures, and increased flow of passengers. The research problem has been defined as follows: How shall the international airport security controls function in the context of regulatory and operational conditions and current and future threats? In reference to the problem, the research hypothesis was defined as follows: Security control in civil aviation consists of screening persons and detecting prohibited articles and mainly depends on the professional competence of security staff and the proper selection and maintenance of electronic assistive devices. Professional competences refer to personnel’s knowledge, experience, qualification, monitoring, operational supervision, and quality control as part of their tasks. The development of new technologies requires the appropriate selection, commensurate with risk analysis, of electronic assistive devices, including equipment, methods, technical means, and their maintenance in a proper technical condition. The paper presents the results of empirical research conducted amongst experienced aviation security forums. Because of its complexity and unpredictability, this problem still leaves a wide margin for improvement and efficiency. The following research methods were used to solve the research problem: theoretical methods and empirical methods: diagnostic survey and expert interview.
