Safety

The task of air navigation services is to ensure sufficient distance between aircraft, both in the air and on the ground. In the air, the vertical distance is at least 1,000 feet (300 m) and the horizontal distance is three to five nautical miles (5.6 to 9.3 km). Even the slightest deviation is immediately registered as an infringement of separation – even if the later detailed analysis shows that the safety of the aircraft was not put at risk.

Since 2015, DFS has been using new, uniform methods laid down by the EU Commission (Risk Analysis Tool – RAT). This means that the values determined since 2015 are not completely comparable with those of the previous years.
