Acceptable Level of Safety Performance (ALOSP), Airport, Risk, Risk Assessment, Risk Management, State Safety Programme (SSP)


This work proposed the development of a methodology for risk management in airports for ICAO’s State Safety Programmes (SSP). To do so we investigated the nature of the airport safety events occurred in busiest Brazilian airports and proposed a risk index capable to provide the Acceptable Level of Safety Performance (ALoSP) ICAO demands to their signatory States. The approach allowed us to rank airports per their risk in relation to the ALoSP calculated and proposed State optimized regulatory actions to where the risk is. Research found the high concentration on risk recurrence among 31 airports. Only 4 concentrated 30% of all the recurrence of risk, 8 were responsible for 50% and 17 represented approximately 80% of the total risk load in Brazilian airport operations. Five groups of airports are proposed as per their safety performance (Safety+2, Safety+1, Neutral, Safety-1 and Safety-2). Their measured performance showed statistically significant differences. Safety+1 group presented a safety performance 1.49 times better than ALoSP and 3.52 times better than worst group of airports (Safety-2). The Safety+2 group is 3.76 times safer than ALoSP and 8.88 times safer than Safety-2 group. Safety-1 group presented a risk level 1.51 times higher than ALoSP and Safety-2 performed 2.35 times riskier than the ALoSP. This matrix way of problem solving brings more effectiveness and rationality to the SSP’s, amplifying their effectiveness.
