摘要

This study conducts a safety analysis at seven Brazilian airports through the application of a method of risk analysis, which considers the occurrence of the following events: landing overrun, takeoff overrun, landing undershoot, and veer-off on landing and takeoff operations; these types of accidents accounts for most accidents that occur on or in the immediate vicinity of the runway. The models employed are based on evidence from worldwide accidents and incidents that occurred during the past 27 years and evaluate the likelihood and severity of event types due to engineering non-compliances at airports. For the purposes of the research provided in this paper, data was collected at seven major Brazilian airports, in order to obtain information on meteorology, operations, airport layout, and to identify main non-compliances that might compromise safety. Analysis for a given day and a critical design aircraft indicate that 10.84% of non-compliances in these airports should not be tolerable, demanding actions to solve these issues; 45.78% are tolerable, which risks could be managed with mitigating actions; 43.37% are acceptable, considering a given level of safety. Additionally, sensibility analysis was done to identify and quantify the impact of several variables on risk. The case-study and its results are useful for engineers and planners, in order to assess risk and to support planning and engineering decisions.
