Occurrence types – event risk classification
Studying ATSB’s event risk classification (ERC) for occurrences in the sector helps to gain further clarity on risk. ERC analysis shows higher safety risk from occurrences related to airspace conflicts such as aircraft separation.
Based on ERC classification the top 3 occurrence taxonomies are:
- near collision
- runway incursion
- airborne collision alert system warning.
Safety factors
ATSB applies safety factors to certain occurrences to identify conditions or factors that contributed to the occurrence.
Safety factors are an event or condition that increases safety risks. This means it increases the likelihood of an occurrence or the consequences associated with an occurrence.
