Software Error Causes Flight Delays and Cancellations

In Germany, a bug in the Air Traffic Control System led to the cancellation of numerous flights at Frankfurt Airport.

This is not the first time that the German Air Traffic Control System has suffered technical problems, this time Frankfurt Airport was affected by an unexpected outage. The operator of Germany's largest airport, Fraport, reported the problem, immediately informing that there would be outages throughout European airspace and thus delays in operations and isolated flight cancellations.

Investigation into the technical problem revealed that it was related to a software failure during theinstallation of an update to the Langen Control System. Although the problem was resolved early in the morning local time, all passengers were instructed that delays and cancellations could be expected throughout the rest of the day before operations returned to normal. The Langen Control Center is responsible for lower airspace in the central regions of Germany, including some of the country's busiest airports such as Düsseldorf, Cologne and Frankfurt.
