Nowadays, air transportation is considered the fastest way to transport people and goods within the shortest time over long distances. Due to growing air traffic trends, the development of advanced Decision Support Tools (DSTs), based on technological advances in communications and navigation in Air Traffic Management (ATM), is important to guarantee sustainable transport logistics to balance airspace capacity with user demands. In this paper, the tuning of Calculated-Take-Off Times (CTOTs) as a tool for mitigating the propagation of perturbations between trajectories in dense sectors is analysed. The proposed methodology uses a powerful tool for predicting potential spatio-temporal concurrence events between trajectories over the European airspace that are removed by considering bounded time stamp adjustments on strategic agreed points of the aircraft trajectory. The proposed approach is based on a robust Constraint Programming model aimed to determine the feasible time stamp agreements considering the Trajectory Based Operation (TBO) interdependencies.
