This event created a real awareness, which has lead to a 11 significant change in the way services and their continuity are approached.

Faced with such a large-scale incident, safety was always guaranteed.

However, we participate after the investigation The en-route delay in order to implement the recommendations and changes recommended by the investigation reports. affected by 19 the 27 May incident For 2015, Belgocontrol failed to achieve its aim to reduce en-route delays. The main cause for this failure is the impact of the power cut experienced on 27 May 2015, which paralysed Belgian airspace and forced air traffic controllers to apply the “clear the sky” procedure consisting of the diversion of all flights to the nearest airports and airspaces. At no time was traffic safety compromised. But the numerous regulations issued at the time caused major delays. Without the impact of this event, Belgocontrol would have achieved its aim and made a positive contribution towards the performance recorded by FABEC. By contrast, Belgocontrol fully achieved its aims relating to the delay in arrivals at airports.
