CREATE: innovative operations and Climate and weatheR modEls to improve ATm resiliencE and reduce impacts

Air operations largely use weather information (visibility, wind, precipitation) to make the air traffic flow safe, continu- ous and efficient. Runway choice, arrival and departure routes are all affected by local weather. Weather causes operational delays, restrictions affect scheduling and operations at and near airports. Visibility and wind affect choice of runway in use. Noise contour limits and night bans may affect choice of routes and type of operations. Weather might also change in a short time. This has an impact on the ATM decision making processes and operational procedures. As climate changes are ongoing, with larger variability in local phenomena, available information on the weather on short and longer notice are increasing and technology is being improved to use this information. Minimizing fuel burn, emissions and contrails, will lead to a reduced impact on the environment and climate. The European project CREATE explore the feasibility of new concepts for the environmental assessment of ATM operations, while becoming more resilient to weather phenomena. CREATE will (1) study the vulnerabil- ity of the ATM system with respect to weather phenomena to improve ATM procedures (2) study the impact of aviation on the environment both short and long term, in order to propose ATM operational changes able to reduce such impact (3) study possible new meteo tools and methodologies to integrate their use in ATM (4) study and propose ATM operational changes X.

Russo ISSNOVA - Institute for Sustainable Society and Innovation Via dei Fiorentini, 21 – 80133 Napoli, Italy to improve efficiency of air traffic management and reduce related environmental impact for both en-route and TMA flight phases, while improving the ATM resilience with respect to weather phenomena (5) validate proposed ATM operational changes to reduce ATM environmental impact and improve ATM resilience with respect to weather. The ATM system will be looked at from the en-route operations and TMA operations perspectives. CREATE will utilize curved trajectories, to be optimized on-board basing on the CREATE optimization tool. Around these tactically modified trajectories, a concept of operation will be devel- oped based on the SESAR principles for TBO and i4D, enabling the Network Manager for more efficient overall flows optimization, strengthen ATM resilience. CREATE will rely on weather ensemble forecasting models, allowing high resolutions and short-range forecasts, thus contribution to the reduction of aviation’s impact on the environment and climate and improve ATM’s resilience to these phenomena. Both forecast and assessment tools will enable CREATE to design and implement the innovative ATM procedures and supporting tools required to reduce ATM environmental impact and improve ATM resilience with respect to weather
