The Greek Air Traffic Controllers' Union has highlighted a recurring issue with the data link to the Merenda hill, which has once again failed, disrupting communications critical for air traffic management. This malfunction mirrors a similar incident from August when a replacement part that the Hellenic Civil Aviation Authority had been evaluating since May 2024 was still undelivered. The union emphasizes that the primary approach radar at Athens, which serves the country's largest airport, is now operating with only one radar instead of the usual three, causing significant concern over air traffic safety.

The controllers pointed out that the loss of data transmission between the Merenda hill and the control centers leaves them without backup frequencies, further jeopardizing flight operations. They expressed their frustration, noting that the only safety net in these situations has been the diligent work of air traffic controllers themselves, who continue to manage air traffic despite the technical failures. The union insists this situation is unsustainable and needs urgent attention to ensure continuous safety and operational efficiency in air traffic management.

This ongoing malfunction poses serious implications for both safety and operational capabilities at one of the busiest airports in Greece. With only one functioning radar, the risks for air traffic are heightened, potentially leading to delays and unsafe landing conditions for incoming flights. The call to address these technical issues is critical, not only for the current situation but also for the future of aviation safety in Greece, as reliance on under-resourced equipment is proving to be a challenge for maintaining high safety standards in air traffic control.
