The coronavirus crisis effects on aviation in 2020 are currently well-documented. Nonetheless, the widely registered low traffic due to the crisis does not necessarily lead to increased air navigation efficiency. Thus, the present work, developed to fulfill the program outcomes for the Master of Science in Aeronautics, Air Traffic Management (ATM) specialization, aimed to investigate what was the impact of the COVID-19 crisis on air navigation efficiency in Brazil. This research question was addressed through a quantitative, nonexperimental, observational approach with two parallel branches, designed to answer two sub-questions. For the first, regarding what was the impact of the crisis on arrival delays in Brazil, a posttest, one group design found no evidence of significant differences in mean arrival delays between 2019 and 2020. For the second, regarding flight times between city pairs, there was no strong correlation between the number of flights in a given route and their respective flight durations. Together, both branches suggested no overall efficiency improvements. In other words, the COVID-19 crisis did not have a significant impact on the air navigation system efficiency, within the Brazilian context. The work was relevant for the ATM industry due to the contrasting findings in other parts of the world and also for helping to develop alternative air navigation efficiency evaluations. Due to the nonexperimental nature of the research design, further investigations are recommended to support a better comprehension of global ATM
