SORT-ATM is a user-friendly software for MITIGA SOLUTIONS capable to provide customer-based solutions for Air Traffic Management during emergency situations involving atmospheric natural hazards. The impact assessment is based on calculations of a unique algorithm that employs in-house HPC atmospheric dispersion models, parameters for flight plan configurations and schedules, aircraft specifics, forecasted weather conditions and other relevant ATM and asset data from clients. We developed and designed the graphical interface to display real-time impacts, allowing to improve emergency management and define mitigation strategies.
