1. Criticality and continuous certification
In aeronautics, but more widely in transport, energy production, nuclear power, finance, healthcare or military applications, many systems are qualified as "critical". The criticality of a system is defined in terms of the consequences that its failure could have in terms of loss of life or destruction of equipment.
The criticality (C) of the functions performed by a system is established in relation to the feared events affecting these functions. It is calculated by taking into account the frequency of occurrence (F) of the feared events, their severity (G) and their detectability (D):
