Abstract

EN The paper presents statistical research results regarding the occurrence of which dangerous aviation events in 141919-2018. The source of the information about the events was the AviationSafetyNetwork website. With the 15use of Excel 2016 and Statistica v. 12 computer programs, five-time intervals were identified in which hazard-16ous aviation incidents took place.17Characterizing the distribution of these events in all periods, due to the technological advancement and capa-18bilities of airplanes, the distribution of dangerous events in the last three periods was compared. The following 19tests were used to verify the statistical hypotheses: x², Shapiro-Wilk, Brown-Forsythe, Kruskal-Wallis. When 20choosing the appropriate test, the following factors were taken into account: the type of measurement scale, 21the dependence/independence of samples, and their number. The standard significance level was assumed to 22be α = 0.05. The consequences and repeatability of aviation events in the identified time intervals were ana-23lyzed. Theresearch questions that were posed were the following: in which seasons of the year, months, days 24of the month, and days of the week did the most dangerous events deaths occur? How often did dangerous 25events take place? Was the distribution of events similar in the identified periods? 26The results of the conducted research allowed to identify five periods in which hazardous events took place and 27demonstrate that in particular periods the distribution of hazardous air events in subsequent seasons, months, 28and days of the week was not the same.
