    Determination of air transport security factors vulnerable to acts of unlawful interference

    by Iryna Vysotska, Alla Valko, Svitlana Pron, Iryna Herasymenko, Fedir Vysotskyi

    The object of research is air transport security system. The prerequisites for implementing security measures in air transport have been investigated. This is due to the fact that the most serious threat to the safety of air transport is unlawful interference acts (UIA), the commission of which is a crime and cannot be justified. Therefore, it is constantly necessary to promote the increase of efficiency in combating this evil at the global level. Factors influencing the safety of the ATS components depending on the features of their functioning have been determined. For the "air transportation" ATS component the most vulnerable object is the airport, where the processes of the initial and final stages of the flight take place. For the "special purpose aviation" component of the ATS, the most vulnerable sector is aviation-chemical work in the agricultural sector. In this sector, aviation protects grain crops with chemicals. It has been found that pesticides can be a significant threat due to their use for the purpose of biochemical terrorism. A mathematical model has been developed and implemented that reflects the dynamics of passenger flow through airport procedures. The dynamic distribution of airport resources for performing screening procedures both during normal operation and when operating under threat conditions was calculated. As a result, extreme cases of resource requirements were identified – for performing security checks lasting an average of 7 minutes per passenger. When the throughput is exceeded by 2 times, the need for the corresponding resources is 4.7 times greater than for performing security checks lasting an average of 3 minutes per passenger and with minimally sufficient process throughput to complete everything within the established time frame

    Constructing a system of integrated management of aviation safety as a key element of airport service quality

    by Alla Valko, Olena Soloviova, Ganna Volkovska, Iryna Herasymenko

    The scientific-practical basis of the quality of passenger and clientele service at the airport were studied. This was prompted by the need to determine the role of aviation safety (AS) and its impact on the quality and competitiveness of airport services. It was proved that within the framework of the system, quality monitoring is performed in the areas of the service of aviation safety (SAS). As a result of research, a quantitative assessment of the level of aviation safety of the airport, which is the basis for making a relevant management decision in the analysis subsystems, was determined. Management , in this case, implies the system of measures to improve the activities of the SAS. A procedure for assessing the quality of airport services, which reveals the essence of aviation safety in the system of airport quality management , was devised. The sequence of assessment of the system of aviation safety, reflecting the cost approach, the application of which involves determining the reserves for ensuring aviation safety in the continuous implementation of the quality management system, was proposed. The share of costs of aviation safety (AS) was determined on the example of three airports by economic elements (the model of criteria for choosing a subject) to determine the cost of ensuring an adequate level of aviation safety. It was proposed to introduce a comprehensive indicator of the quality of aviation safety for its functional components, which further makes up the integrated indicator of the quality of provided services. As a result of calculations, the amount of payment for aviation safety using adjustment coefficients to counteract the threat of a possible act of unlawful interference (AUI) will increase. This enables an aircraft company to form timely a reserve to prevent or eliminate the consequences of the AUI by including the aviation safety fee in the total cost of air transport services.
