A system and a computer-implemented method for evaluating uncertainty of a predicted trajectory infrastructure is disclosed The method comprises collecting (202) a plurality of data sets from a predicted trajectory (104): comprising providing (204) an aircraft intent description (120) based on the predicted trajectory (104); selecting (206) both a point in time and one or more variables among the collected plurality of data sets as sources of uncertainty (134); representing (208) each selected variable at the selected point in time as a uni-variable polynomial expansion; representing (210) each non-selected variable by a single point; and combining (212) selected and non-selected variables into a multivariable polynomial chaos expansion representing a stochastic prediction of the aircraft's trajectory at the selected point in time and a measurement of a sensitivity of the prediction to each of the selected one or more sources of uncertainty.
