Safety management

At DFS, the top corporate objective is to keep the involvement of the air navigation services in causing an aircraft accident risk as low as possible. Achieving a high safety level in German airspace takes absolute priority over economic aspects. Safety at DFS is constantly checked and documented by different units, both inside and outside the company. Any change made to the “air traffic management system” is systematically checked for all potential hazards, while the associated risks are assessed and reduced to an acceptable level by taking suitable action. For example, annual audits required for ISO certification are conducted by the technical inspection association TÜV. For DFS to be allowed to perform air navigation services at all, it has to be certified. DFS has a safety management system in place that works on a proactive basis and meets national and international parameters. The system is divided into Corporate Safety and Security Management and safety management units of the Control Centre and Tower Division. They report directly to the Chairman of the Board of Managing Directors. Thus it is organised independently of operational management.

The Federal Supervisory Authority for Air Navigation Services (BAF), which performs the functional supervision of DFS, also regularly and independently examines all DFS processes.

DFS regularly conducts in-house safety surveys according to Regulation (EU) 1035/2011 and safety audits according to ICAO Doc 9859 to ensure a high level of safety. The safety surveys are conducted by IntACT, the International Audit Cooperation Team, whose members come from partner ANSPs in FABEC.
