On 10 May, EUROCONTROL published a data snapshot of transponder interrogations taken from 26 April 2021, which highlighted risks to the overall ATC picture presented to controllers.

The latest data snapshot looks at the overload on the use of surveillance radar, demonstrating the need for optimisation of the surveillance infrastructure in order to support improvements in safety, emission, and overall cost of the system.
