Severe Problem in Greek FIR: Flights Grounded or Diverted

A significant issue with radio frequencies is impacting Greek airspace, leading to reduced capacity and flight cancellations/diversions. The Hellenic Civil Aviation Authority has issued a relevant directive, and departures, particularly from Eleftherios Venizelos Airport, have become challenging. Aircraft already in the air will be landed using manual procedures, without automated systems. An experienced pilot states that aircraft will need to follow specific procedures in case of complete system disruption, and emphasizes the need to modernize the HCAA systems, despite substantial revenue from Eurocontrol. The problem appears to be located in the central radio frequency systems of the Athens and Macedonia Area Control Centers, with the restoration time currently unknown.
