Abstract: A computer-implemented method, system, and computer program product for managing passenger information. Communication between an electronic device of a user and an airline data server is established. The user is identified as a passenger for a departing flight at an airport. Flight status information associated with the passenger is retrieved via the airline data server. Passenger location information is retrieved with the electronic device. An estimated time for the passenger to reach the boarding gate is computed based on the passenger location information and the flight status information. A probability of the passenger missing the flight is computed based on the estimated time for the passenger to reach the boarding gate and the flight status information. A notification is produced according to the computed probability.

Abstract: The present disclosure relates to the secure transmission of an aircraft trajectory that is to be flown or that has been flown. A ground-referenced description of the trajectory of the aircraft expressed in ground-referenced parameters is converted, using a description of an imaginary atmospheric model describing imaginary atmospheric conditions along the trajectory, into an air-referenced description of the aircraft trajectory expressed in air-referenced parameters. For decryption, knowledge of the imaginary atmospheric conditions allows the air-referenced description of the aircraft trajectory to be converted back into the ground-referenced description of the aircraft trajectory. Thus, the ground-referenced trajectory may be though of as the plain text, the imaginary atmospheric model as the cipher key and the air-referenced trajectory as the cipher text.

Abstract: The present invention provides a system and method of producing a description of the flight intent of an aircraft expressed using a formal language. The description may be used to generate a predicted aircraft trajectory, for example by air traffic management. Rules are used in association with information provided to express the flight intent of the aircraft in a formal language. The flight intent describes a flight in terms of flight segments, and provides information of the path to be flown and how it is to be flown. The flight intent does not necessarily define unambiguously the aerodynamic configuration of the aircraft and the motion of the aircraft during the flight. The flight intent is used alongside other information to generate the aircraft intent that does describe unambiguously the aircraft's trajectory.

Abstract: The present disclosure provides a computer-implemented method of generating a description of aircraft intent expressed in a formal language that provides an unambiguous description of an aircraft's intended motion and configuration during a period of flight. A flight intent description is parsed to provide instances of flight intent that span a flight segment, the flight segments together spanning the period of flight. The parsed flight intent is converted into parametric aircraft intent by generating an associated flight segment description for each flight segment that comprises instances of flight intent to close all associated degrees of freedom of motion and of configuration of the aircraft. At least some flight segment descriptions contain a parameter range, and the method further comprises optimizing the parametric aircraft intent by determining an optimal value for the parameter of each parameter range.
