Highly sophisticated technology to guide aircrafts safely through german airspace.


Since 2008 ask – Innovative Visualisierungslösungen GmbH contributes to the design, development and commissioning as well as maintaining software solutions for German Air Traffic Control with substantial quality assurance tasks. METFROG is one of the software solutions we have delivered on behalf of DFS to perform air traffic control safely and efficiently by harnessing weather information of German Weather Service DWD for flight planning and controlling.

METFROG uses highly sophisticated technology to display weather information. Since 2010 MEFROG is operational at DFS control centers (Langen, Bremen, Karlsruhe, Munich) to guide aircraft safely through german airspace and on towers of 16 international german airports to ensure that air traffic at German airports is handled safely and punctually. Another solution of our company for DFS is the WTQ (Wind, Temperature, QNH) Service application which manages and processes incoming weather data. It performs weather information conversion and operationally supplies the DFS end systems ATCISS and P1/VAFORIT with the expected data formats.
