Abstract

This disclosure generally relates to devices, systems, and computer-implemented methods for simulating flights. Specifically, methods are described that comprise the operations of receiving flight information for one or more flights to be simulated; receiving historical flight information for historical flights; determining, based on the flight information and the historical flight information, probabilities for one or more flight parameters of the one or more flights to be simulated; determining a current state of the one or more flights to be simulated based on the determined probabilities for the one or more flight parameters; determining a next state of the one or more flights to be simulated based on the current state; and outputting one or more evaluation parameters associated with the next state of the one or more flights to be simulated.
