Summer thunderstorms have a strong impact on air traffic - New procedures help alleviate the problem

- Langen, Germany.

Compared to previous summers, the 2016 season has suffered an unprecedented amount of severe weather. Heavy thunderstorms have disrupted traffic flows and caused significant delays. Some cells have extended vertically to an altitude making it impossible to fly over them. To ensure the safety of passengers, departures have had to be postponed until the weather fronts have either dissipated or moved on. This means that passengers have had to wait on board for an hour or longer before finally taking off. The FABEC air navigation service providers have addressed this problem and worked out concrete solutions.

In cooperation with the control centers in Langen, Karlsruhe, Zurich, Marseille and Padua, the Munich control center has designed re-routings to avoid thunderstorm cells. It is, for example, not possible to fly a direct route from Munich to Madrid if there is a storm cell above Lake Constance. In this situation, the air navigation services offer the airline dispatch an alternative route that leads south via Italy and then to the west towards Spain. The airline can decide whether to use this alternative or not: would they prefer the longer flight path or a longer wait on the ground. At the moment, DFS has agreements on the implementation of this procedure with four airlines – Lufthansa, Condor, Lufthansa Cityline, and Air Berlin.

Based on the positive results in Munich, further alternative routes will be developed in the coming months involving traffic departing to the northeast and in a second step headed towards Munich. At the FABEC level, the results of this pilot project will be passed on to FABEC partners who will undertake further implementations taking their local circumstances into account.
