Duration of possible delays at Zurich Airport open

"Our teams are currently working flat out to rectify the technical problem," said the media office at the request of Keystone-SDA. The safety of air traffic is guaranteed.

Approach capacity in Zurich was reduced by 30 percent from the start of operations as a precautionary measure. A spokeswoman for Zurich Airport said shortly before 6 a.m. that there had been no cancellations due to the disruption so far. Passengers would be informed of the status of their flights by their airlines. The spokeswoman added that capacity would be reduced anyway due to the bise.

According to Skyguide, the technical problem occurred at the control center in Dübendorf ZH. A system that supports air traffic controllers in guiding incoming aircraft was not reliably displaying aircraft with major delays, skyguide wrote on Wednesday night. Instead, the controllers would hand over the flights concerned using a tried-and-tested manual procedure. This takes more time. Skyguide will provide information on the further course of events during the course of the morning.
