From hazards to risks: Lessons learnt from the procedure applications of the Swiss Low Flight Network (LFN).
Our basic philosophy is that risks are inherent factors that must be addressed in the context of risk management. And this risk management must be an essential part of the top-level management process. The goal is to avoid critical situations per se, which can lead to serious incidents or accidents.
As can be seen from the corrected title, it is not about hazards and risks, but that hazards lead to risks. By adding a specific operational exposure-weighted probability of occurrence to a hazard, the hazard becomes a risk.
By adding a specific operational exposure- and outcome-weighted probability of occurrence to a hazard, we turn the hazard into a risk. In practical terms, this means that other aircraft always represent a hazard. The risk of a mid-air collision (MAC) is significantly higher in heavily used and uncontrolled airspace than in airspace that is hardly used.
In the vast majority of cases, an accident is not caused by a single mistake. Years of accident research have shown that accidents are caused by various intentional and unintentional sequential changes in the situation. Therefore, the probabilities of the occurrence of the situation changes of the basic risk, then the escalation of the risk and finally the required probability of occurrence or manifestation of the risk must be determined and offset against each other.
In order to quantitatively assess the probability of an escalation into a more dangerous situation within the scope of the assessment, technical, operational and other barriers are identified and taken into account to a de-escalation of an already escalated situation to a basic (lower risk) initial situation.
The presentation will show a pragmatic scientific approach to modern risk management.
