Today, especially at larger airports, controllers use air traffic control support systems to help them organise and guide arriving and departing traffic. However, these systems do not yet have the capability to use weather measurements or forecasts to calculate flight routes around, for example, thunderstorms. “If extreme weather areas occur, the pilots decide on which side and at what distance they will fly around them. Controllers then have to calculate manually separation infringements with other aircraft,” explains Antonio Parodi, coordinator of the SINOPTICA project.
The project developed a module for an extended arrival manager (Extended AMAN) system that uses current weather information and forecasts to plan the approaching traffic around the developing weather at an early stage. It is integrated directly into the working position of approach controllers and works seamlessly with existing systems. In case a severe weather area blocks the route, the AMAN calculates new approach routes around the dangerous areas with new arrival times and new positions in the landing sequence. The controllers responsible get advisories where and for how long the aircraft have to leave the standard approach routes and at which target times they will be at the main waypoints of the route. Additionally, the systems allow controllers to visualise the predicted and animated severe weather areas.
Weather and climate change are inextricably linked, which is what prompted the CREATE project to assess the impact of ATM operations on the climate, while also improving resilience to weather phenomena in a changing climate. “The changing global climate increases the future severity and frequency of disruptive weather phenomena. This deteriorates the reliability
