Serious and major incidents are the highest severity classes of incidents. These incidents tend to be independent of reporting attitude by humans and are as such a commonly used indicator with ANSPs around the world.
Serious and Major incidents 2018-2022
A total of 2,540 incidents were registered in 2022.
An occurrence is any safety-related event that endangers or, if not corrected or addressed, could endanger an aircraft, its occupants or other persons, and in particular includes an accident or a serious incident.
An investigation has been carried out into all incidents. This number was more than the year before (2021: 1,807 incidents). This increase is due to the increase in the number of flight movements in 2022 compared to the previous year. The COVID-19 restrictions that were still in place in 2021 were lifted.
In the figure above, the reported occurrences are normalized for the number of flights and split into flying and ground operations. The trend of the twelve-month moving average of the number of serious occurrences, the two highest categories 'serious' and 'major', per hundred thousand aircraft movements is stable at the end of 2022 compared to the end of 2021. The use of this indicator is generally accepted internationally, because serious incidents have better reporting reliability.
