The challenge

CREATE project will study the vulnerability of the ATM system with respect to weather phenomena, in order to improve ATM procedures so that vulnerability can be reduced.
Studying the impact of aviation on the environment both short and long term (climate), in order to propose ATM operational changes able to reduce such impact.
Studying possible new meteo tools and methodologies, in order to integrate their use in ATM.
Validating proposed ATM operational changes in order to reduce ATM environmental impact and improve ATM resilience with respect to weather.

The 4D trajectory

The 4D trajectory optimisation and replanning concept proposed in CREATE will be designed as a multi-objective optimisation framework, taking into account the different components of the environmental impact of operations and addressing the trade-offs and interdependencies among them (Pareto optimality).
