(54) Safety nets for alerting of hazardous situations in air traffic


(57) The present invention relates to a system and a method for alerting of a potentially hazardous situations in air traffic on the basis of surveillance data wherein predicted conflicts are identified based on the prediction of future air traffic situations. A basic idea of the present invention consists of defining a stochastic model for trajectory prediction in which the uncertainty of the prediction is represented as a function of the prediction time. The stochastic model for predicting trajectories is preferably used to construct a stochastic model for conflict prediction. In the latter model, probabilities of conflict are compared to minimum confidence levels and allow to decide whether a given predicted situation is a predicted conflict or not.
