The Dutch Safety Board has published the Quarterly Aviation Report over the third quarter of 2022. In the third quarter the Dutch Safety Board concluded four investigations into airproxes. Three further investigations were started this quarter. Airproxes are situations in which, in the opinion of a pilot or air traffic services personnel, the distance between aircraft as well as their relative positions and speed have been such that the safety of the aircraft involved may have been compromised.
The Safety Board is attempting to gain a greater insight into the common factors that played a role in the investigated airproxes. A notable development since 2021 is the increase in the number of reports of airproxes involving a motorised aircraft and a glider, which took place around aerodromes being used for glider activities. The Safety Board has considered these types of occurrences in past quarterly reports. In a future report, the Safety Board will present the findings of its exploratory investigation into airproxes.
More about investigations into aviation incidents can be found in the Quarterly Aviation Report Q3 2022.
