Claim 6:
7. A method, executed on an aircraft icing prediction computer system, of predicting icing of an aircraft, the method comprising:
performing a regression analysis of real-time environmental data collected during a flight of the aircraft using a supervised learning algorithm to predict a risk of icing;
determining a metric of confidence in the predicted risk of icing using a reinforcement learning algorithm and based on the regression analysis; and
based on determining that the predicted risk of icing does not meet an acceptable level of safety based on user-defined parameters, at least one of:
generating an icing risk alert to an onboard crewmember or a remote operator; and/or
recommending an icing avoidance maneuver; or
based on determining that the predicted risk of icing meets the acceptable level of safety, not issuing the icing risk alert, not recommending the icing avoidance maneuver, and adding the environmental data and the predicted risk of icing to a library of learning stored in a database.
