BERLIN, March 25 (Xinhua) -- Ongoing software problems at Germany's air traffic control (DFS) caused restrictions in air traffic throughout Germany on Monday.
Germany's largest airport in Frankfurt announced that the "software malfunction" at the German air traffic control would cause "delays in operations and flight cancellations".
At Frankfurt airport alone, 68 flights of around 1,400 planned flight operations were cancelled on Monday morning, a spokesperson of Frankfurt airport confirmed to Xinhua.
On Wednesday last week, the German air traffic control DFS had already reduced traffic capacity in German airspace by 25 percent due to software problems at DFS's air traffic control center in Langen near Frankfurt.
According to DFS, a "not accurately functioning" control system which provides air traffic controllers with important data such as aircraft type, flight routes and expected overflight time of aircrafts in German airspace would be the reason for the current disruptions in German air traffic.
However, "all other air traffic control systems are available without restriction" and the other DFS control centers in the cities of Munich, Bremen and Karlsruhe would not be affected by the software problems, according to DFS.
"Air traffic safety is not affected" by these disruptions, DFS said and announced, that "an alternative software" is scheduled to be put into operation on Wednesday night this week.
