A method is provided for optimizing a flight of an aircraft with at least one segment of formation flight. The method includes accessing flight plans for flights of a fleet, and transforming the flight plans into values of a set of features that describe segments of the flights. The values are applied to a machine learning model trained to predict the segment(s) during which the aircraft is within a region that includes at least one second aircraft of the fleet that is thereby capable of serving as a leading aircraft in the segment(s) of formation flight in which the aircraft is a trailing aircraft. A notification is sent to the aircraft of the segment(s) and the second aircraft capable of serving as the leading aircraft. And a second notification is sent to the second aircraft of the segment(s) and the aircraft capable of serving as the trailing aircraft.

Disclosed is an open world communication device with an aircraft avionics system including an application component. The device further includes an interfacing component with a communication module able to intercept each request sent by the application component and a clone of the avionics system able to test each request intercepted by the communication module in order to determine the status of the request between a conforming status and a non-conforming status. The communication module is able to send to the avionics system, only the requests having the conforming status.

Aspects of the present disclosure provide systems and methods for evaluating a flight plan with respect to an executed route of an aircraft. An example method includes obtaining data associated with a route of a vehicle. The method further includes determining a first cost index associated with the route based at least in part on a segment of the data. The method further includes comparing the first cost index to a second cost index associated with a plan for the route. The method further includes determining a cost penalty associated with the route based at least in part on the comparison between the first cost index and the second cost index. The method further includes performing one or more actions associated with the vehicle in response to determining the cost penalty.

A flight management system for an aircraft, includes a critical first avionics module for trajectory calculation, i.e. a module the integrity level and availability level of which are specified by regulatory standards in force, delivering as output a safe trajectory, based on a flight plan; a second module for trajectory calculation that is less critical than the critical first module, i.e. a module the integrity level and availability level of which are lower than those of the first module, delivering as output an improved trajectory that is less safe than the trajectory delivered by the critical first avionics module, based on a flight plan; a critical avionics module for trajectory verification, configured to validate or invalidate the safety of the less safe improved trajectory; and a critical avionics module for decision-making configured to select a trajectory from the safe trajectory and the less safe trajectory.
