Software issue at DFS solved

The software problems at the air traffic control centre of DFS Deutsche Flugsicherung in Langen have been solved. The restrictions in air traffic were cancelled at 4:00 hrs local time on Thursday morning.

28.03.2019.- The malfunctioning of the electronic flight progress strip system at the air traffic control centre in Langen was rectified after the DFS technicians implemented the previous, well-tested software release in the night from Wednesday to Thursday.

Since this morning, DFS has been providing the full capacity for the Langen airspace again . This airspace reaches from the French border to the west up to Thuringia to the east, and from Lake Constance to the south up to Kassel to the north.

In the past few days, the capacity provided by the Langen control centre had been reduced by 25 percent for safety reasons. As a consequence, traffic peaks could no longer be met without delay. Despite the capacity restrictions following the software problem, the Langen control centre safely handled the seasonal increase in flight movements during the past few days and controlled more traffic overall compared to the previous weeks.

During the malfunction, the safety of air traffic was never impaired.
The other DFS control centres in Munich, Bremen and Karlsruhe were not affected by the issue. Robert Schickling, Managing Director of DFS Deutsche Flugsicherung GmbH, said: “We would like to apologise to all passengers for any inconvenience caused. The reduction of air traffic control capacity was a precautionary measure to ensure safety in airspace and, as a consequence, passenger safety.”
