Patent number: 9507053Abstract: The present disclosure relates to a method of inferring data relating to atmospheric conditions within an airspace of interest using observations of aircraft trajectories. Information relating to aircraft intent may also be inferred. Aircraft flying within the airspace are identified, and their trajectories and aircraft type are determined. Aircraft performance data relating to that type of aircraft is retrieved from memory, along with any filed aircraft intent data. Then, the atmospheric conditions data and, optionally, any missing aircraft intent data that, in combination with the filed aircraft intent data and the aircraft performance data, would give rise to the determined trajectory for each processed aircraft are inferred. The atmospheric data and optionally the missing aircraft intent data are provided as an output.Type: GrantFiled: December 13, 2013Date of Patent: November 29, 2016Assignee: THE BOEING COMPANYInventors: Francisco A. Navarro, Eduardo Gallo

Publication number: 20160109579Abstract: The invention relates to a method for computing a bound B up to a given confidence level 1-4, of an error in a state vector estimation KSV of a state vector TSV of a physical system as provided by a Kalman filter. The method decomposes the errors of the Kalman solution as a sum of the errors due to each of the measurement types used in the filter, In addition, the contribution of each type of measurement is bounded by a multivariate t-distribution that considers the error terms from all the epochs processed. Then, the method implements three main operations: computing a probability distribution of the measurement errors for each epoch and measurement type; summing the previous distributions to obtain a global distribution that models the Kalman solution error; and computing the error bound B for a given confidence level from the resulting distribution.Type: ApplicationFiled: October 16, 2015Publication date: April 21, 2016Inventor: PEDRO FRANCISCO NAVARRO MADRID

Patent number: 9250099Abstract: The present invention provides a computer-implemented method of producing a description of aircraft intent expressed using a formal language. The description may be used to predict aircraft trajectory, for example by air traffic management. Rules are used in association with information provided to generate a set of instructions describing both the aerodynamic configuration of the aircraft and the motion of the aircraft. These instructions are checked to ensure that they describe unambiguously the aircraft's trajectory. The instructions are then expressed using a formal language.Type: GrantFiled: January 25, 2015Date of Patent: February 2, 2016Assignee: THE BOEING COMPANYInventors: Francisco A.

Patent number: 9153136Abstract: 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.Type: GrantFiled: January 27, 2012Date of Patent: October 6, 2015Assignee: The Boeing CompanyInventors: Javier Lopez Leones, Enrique Casado, Miguel Vilaplana, Francisco A. Navarro

Publication number: 20150253779Abstract: Example aircraft intent processors are described herein that can be used both for the prediction of an aircraft's trajectory from aircraft intent, and the execution of aircraft intent for controlling the aircraft. An example aircraft intent processor includes an aircraft intent input to receive aircraft intent data representative of aircraft intent instructions, an aircraft state input to receive state data representative of a state of the aircraft, and a residual output. The aircraft intent processor is to calculate residual data representative of an error between a state of the aircraft commanded by the received aircraft intent data and the state of the aircraft expressed by received state data, and output the residual data via the residual output.Type: ApplicationFiled: March 5, 2015Publication date: September 10, 2015Inventors: Francisco Navarro, Carlos Querejeta, Ernesto Valls Hernandez, Francisco García de Blanes, Luis D'Alto

Patent number: 8977411Abstract: 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 description of flight intent is parsed to provide instances of flight intent, each instance of flight intent spanning a flight segment. For each flight segment, an associated flight segment description is generated that comprises one or more instances of flight intent that describe the aircraft's motion in at least one degree of freedom of motion. One or more instances of flight intent are added to flight segments to close all degrees of freedom of motion. The flight segment descriptions are collated thereby providing a description of aircraft intent for the period of flight expressed in a formal language.Type: GrantFiled: May 24, 2013Date of Patent: March 10, 2015Assignee: The Boeing CompanyInventors: Enrique Juan Magana Casado, Juan Alberto Besada, Javier Lopez Leones, Ana Maria Bernardos Barbolla, Guillermo Frontera, Francisco Navarro

Patent number: 8843302Abstract: A method of detecting conflicts between aircraft passing through managed airspace, and to resolving the detected conflicts strategically. Air traffic control apparatus arranged to manage airspace through which aircraft are flying is provided that comprises processing means configured to receive aircraft intent data describing an aircraft's intended flight path, to launch a conflict detection procedure in which it computes a user-preferred trajectory for each of the aircraft based on the aircraft intent and determines whether any conflicts will arise, to launch a conflict resolution procedure in which it calculates revisions of the aircraft intent of the conflicted aircraft to remove the conflicts, and to transmit to the aircraft the revised aircraft intent data.Type: GrantFiled: May 24, 2013Date of Patent: September 23, 2014Assignee: The Boeing CompanyInventors: Francisco Garcia de Blanes, Miguel Vilaplana, Isabel del Pozo de Poza, Francisco A.

Patent number: 8744649Abstract: 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.Type: GrantFiled: May 24, 2013Date of Patent: June 3, 2014Assignee: The Boeing CompanyInventors: Enrique Juan Magana Casado, Francisco Navarro, Juan Alberto Besada, Javier Lopez Leones, Miguel Vilaplana
