A radar system failure at air traffic management provider Skyguide restricted flight operations at Zurich Airport for approximately one hour on Tuesday afternoon. The technical malfunction struck at 14.15 local time, halting all outbound departures before limited operations gradually resumed.
Radar System Failure Halts Departures
Operations remained completely frozen for half an hour before a small private flight managed to depart at 14.45. Another hour passed before an EasyJet flight bound for Edinburgh successfully left the gate, marking the gradual resumption of traffic.
Vladi Barrosa, a media spokesperson for Skyguide, explained to reporters that the disruption stemmed directly from a failure within the system responsible for generating radar displays for air traffic controllers. Because technicians have not yet identified the root cause of the glitch, the company implemented a preventative capacity reduction across Swiss airspace.
Did You Know?
Skyguide previously had to reduce capacity due to a technical problem in its control tower during the spring, according to company records.
Skyguide halves airspace capacity after technical fault
In response to the unresolved technical fault, Skyguide cut Swiss airspace capacity to 50 percent as a precautionary measure. Barrosa issued an apology to airline partners and affected passengers while confirming that investigators currently have found no indications of a cyberattack.
The 50 percent capacity cap is likely to produce rolling delays across the network, with airports in Zurich and Geneva facing the heaviest disruptions. Airlines and passengers must anticipate schedule adjustments until engineers fully diagnose and repair the radar generation software.
Airspace capacity remains restricted following radar glitch
What caused the disruption at Zurich Airport?
The disruption was caused by a problem in the system that generates radar pictures for air traffic controllers. Skyguide confirmed that the exact cause of the glitch remains unidentified.
Are flights still operating normally in Swiss airspace?
No, Swiss airspace capacity remains restricted to 50 percent as a precaution. This limitation is expected to cause temporary delays, particularly at the airports in Zurich and Geneva.
Is there any suspicion of a cyberattack?
Skyguide stated that there are currently no indications that the radar system failure was the result of a cyberattack.
