Perturbation management of 4D trajectories.

C-SHARE, Joint ATM Cognition through Shared Representations, aimed to develop a novel representation of the tactical and strategic air traffic management tasks – a common shared representation (model of the world) that underlies both the actions of the automation and the cognition of the human actors. This so-called Functional Airspace Representation (FAR) can act as a visual interface for the human operator and provides the principles and input for higher levels of automation such as long- and short-term planning, revising, and monitoring of 4DT’s and highly-advanced conflict detection and resolution algorithms.
