ANÁLISE DOS GRAUS DE VOO DE FORMATURA DE DOIS AVIÕES

Abstract

The aim of this article is to compare the grades obtained in formation flight with two aircraft in the Second Air Instruction Squadron (2nd AIS) with and without simulated instruction. The simulated training used the X-Plane 11 Simulator, in the digital version of the aircraft used in the 2nd AIS, NEIVA T-25 UNIVERSAL. The data consist of the grades from the periods of 2014 to 2018 and from 2022 to 2023, representing, respectively, the years without and with simulated instruction. The analysis methodology was conducted through the use of the R language with graphical analysis and t-tests, Mann-Whitney, Anova, and Kruskal-Wallis tests. The results of the t-test and Anova point towards rejecting the hypothesis of equality between the means of the grades with a p-value of approximately zero for the independent grouped data of the year and for the comparison of grades between the years. Similarly, the Mann-Whitney and Kruskal-Wallis tests indicate rejecting the null hypothesis in favor of the alternative hypothesis that the groups are sampled from populations with different distributions, with one of the populations exhibiting stochastic dominance. Post-hoc analysis was performed with the Tukey HSD and Dunn tests, which show significant differences between years with and without simulated instruction.
