Patent number: 8234068Abstract: A present novel and non-trivial system, module, and method for constructing a flight path used by an avionics system are disclosed. A processor receives flight plan data and object data associated with terrain and obstacles. Free cells are extracted above the objects using a recursive space decomposition technique, and a reference path is formed through traversable free space determined from the availability of free cells. In an additional embodiment, threat data associated with hostile military weaponry and significant meteorological conditions could affect the availability of free cells. A genetic algorithm applying genetic operators which include mutators is employed with aircraft kinematic constraints to refine the reference path used to form a population of best path candidates. When a best path is reached after cycling through a re-generation process of path candidates, flight path data representative of the best path is generated and provided to at least one avionics system.Type: GrantFiled: January 15, 2009Date of Patent: July 31, 2012Assignee: Rockwell Collins, Inc.Inventors: Shih-Yih Young, Kristen M.

Patent number: 8200433Abstract: The present disclosure is directed to a Synthetic Vision System (SVS) view combined with information from navigation charts. The operator of a vehicle is not required to mentally combine separate SVS view and navigation charts, increasing situational awareness and decreasing complexity. A synthetic terrain representation is generated, combined with navigation chart information, and displayed. Additionally, the combination may include an indicator indicating the intended path of the current planned course. The combination may be generated with less detailed navigation chart information when further away or more detailed navigation chart information when close, displaying more detail as landmarks are approached. The combination may include indicators representing one or more navigation aids based on information in the navigation charts. The combination may include text based on navigation chart information.Type: GrantFiled: August 24, 2007Date of Patent: June 12, 2012Assignee: Rockwell Collins, Inc.Inventors: Alan E.
