Patent number: 9728090Abstract: The management system plots the route to be flown in a flight plan, at least partially, by a chaining of published navigation procedures accessible from a NavDB navigation database and constituted of sequences of waypoints and/or turn points associated with specific flight constraints. It comprises a mirror memory storing the latest versions of the published navigation procedures, modified by the crew of the aircraft during the progress of the flight plan and means of substituting these latest versions stored in the mirror memory for the published versions of the navigation procedures during a change in the route predicted in the flight plan obtained by a new chaining of navigation procedures, some of which are taken from the preceding chaining. This makes it possible, during a change of navigation procedure, to take account of specific flight constraints already entered during the progress of the flight but not appearing in the published navigation procedures.Type: GrantFiled: November 14, 2006Date of Patent: August 8, 2017Assignee: THALESInventors: Elias Bitar, Stephane Leriche, Christophe Caillaud

Patent number: 8150623Abstract: The present invention relates to a method allowing a modification of the flight plan of an aircraft in a semi-automated manner. The invention presents the main advantage of affording the crew of an aircraft a method for aiding the rejoining of a flight plan requiring only a designation by an operator of the new active reference that he wishes to use for guiding the aircraft.Type: GrantFiled: November 17, 2008Date of Patent: April 3, 2012Assignee: ThalesInventors: Elias Bitar, Christophe Caillaud

Patent number: 8121783Abstract: The present invention relates to a method for selective filtering of a flight plan according to the operational needs, and it is characterized in that elements specific to the structure of the flight plan are added by the flight management system according to the nature of the elements inserted by the operator onto the flight plan, in order to determine whether these elements should or should not be taken into account for their use in the computations relating to the flight plan. This operator may, on his MMI (man-machine interface) carry out visual filterings of certain characteristic points or portions of the flight plan. This method makes it possible to add elements to a flight plan without modifying its essence and above all the maneuvers that are associated therewith.Type: GrantFiled: December 7, 2007Date of Patent: February 21, 2012Assignee: ThalesInventors: Elias Bitar, Stéphane Leriche, Christophe Caillaud

Patent number: 8046119Abstract: The parts of the flight plan of an aircraft corresponding to lateral trajectories at low altitude can comprise passages with limited lateral freedom of deployment because of risks of collision with the ground, or because of obstacles on the ground. The method makes it possible to signal them for the attention of the crew, so that said crew should redouble their attention. To do this it uses the display, on an onboard navigation screen, of a vertical profile of margin of maneuver relating to the navigation band widened to the right and to the left by lateral margins of maneuver, superimposed on the vertical navigation profile relating only to the navigation band.Type: GrantFiled: June 3, 2005Date of Patent: October 25, 2011Assignee: ThalesInventors: Elias Bitar, Nicolas Marty

Patent number: 8032266Abstract: This method facilitates the joining, by an aircraft, of a secure zone, without constraint of deployment in the horizontal plane, in particular when the latter is threatened by a risk of collision with the ground or by a risk of penetration into a forbidden zone which cannot be resolved by a purely vertical avoidance maneuver. It consists in selecting a point for joining a zone of free lateral deployment by means of a criterion of minimum cost of the initial maneuver of turning at the start of the trajectory for joining the possible points of access to the zones of free lateral deployment.Type: GrantFiled: March 22, 2005Date of Patent: October 4, 2011Assignee: ThalesInventors: Elias Bitar, Nicolas Marty

Patent number: 7786900Abstract: Navigation of an aircraft is facilitated through the displaying on a map of an over flown region, and of the limits of zones within range of the aircraft in an emergency situation. The points of the zones within range of the aircraft are tagged on the basis of: an estimate of the vertical margins to reach these points, taking into account non-maneuverability zones neighboring the aircraft to be circumvented; a vertical flight profile to be complied with; and a safety height margin.Type: GrantFiled: October 12, 2006Date of Patent: August 31, 2010Assignee: ThalesInventors: Elias Bitar, Nicolas Marty

Patent number: 7739035Abstract: This method allows the calculation, using a terrain elevation database, of a map of the distances of the points accessible to a mobile object subjected to dynamic constraints evolving with its time of travel, for example an aircraft having an imposed vertical flight profile, the distances being measured solely according to paths achievable by the mobile object. It implements a propagation-based distance transform which catalogs the achievable paths going from a goal point whose distance is to be estimated to a source point which is the origin of the distance measurements and likens the distance of the goal point to the length of the shortest achievable path or paths.Type: GrantFiled: September 8, 2004Date of Patent: June 15, 2010Assignee: ThalesInventors: Elias Bitar, Nicolas Marty

Patent number: 7733243Abstract: The device relates to the signaling, to the pilot of a moving vehicle, for example an aircraft, of its lateral maneuvering margins taking into account obstacles placed in its maneuvering zone. This device determines, over the maneuvering zone of the moving vehicle, the contours of a first type of risk region that must be bypassed and those of two other types of risk region consisting of lateral margins surrounding the first type of risk region, of widths less than separation thresholds or their upper limit considered necessary for a lateral maneuver without space constraint and displays them for the pilot of the moving vehicle. The determination of the separation thresholds takes into account the bearing angle under which a point of the contour of a region of the first type is seen from the moving vehicle.Type: GrantFiled: July 4, 2005Date of Patent: June 8, 2010Assignee: ThalesInventors: Elias Bitar, Nicolas Marty

Publication number: 20100100258Abstract: The invention relates to a method and an associated device making it possible to avoid guidance command input errors by the crew. Since the course and the radial are linked by different relationships depending on whether the aircraft is approaching or moving away from a point, the procedures from air traffic control may be given either in course or in radial, and since the FMS system can also require the input of one of the two values, the number of possible different combination creates a situation of ambiguity that is prejudicial to the safety of the flight. To resolve this problem, the invention proposes a systematic display in text mode and/or in graphic mode of the input datum (course or radial) and of the other for verification by the crew.Type: ApplicationFiled: September 11, 2009Publication date: April 22, 2010Applicant: THALESInventors: Elias Bitar, Christophe Caillaud

Patent number: 7693613Abstract: In distance maps used in order to facilitate the navigation of craft such as an aircraft, the distances estimated take into account obstacles to be circumvented but not the maneuverability of the craft. The adaptation route required by the craft in order to take the right direction is not taken into account so that certain distance estimates for accessible points located in the neighborhood of the craft are unrealistic. In order to make a distance map more realistic, it is proposed that an obstacle of concave shape associated with the craft be added behind the position of the craft, forcing the estimations of distances to be circumvented an area that is inaccessible to the craft for reasons of maneuverability.Type: GrantFiled: February 9, 2005Date of Patent: April 6, 2010Assignee: ThalesInventors: Elias Bitar, Nicolas Marty

Patent number: 7668625Abstract: This lateral maneuverability map shows the area of movement of a vehicle with the contours of the regions of complete freedom of lateral movement. It is generated from a distance map listing the distances of the points of its regions that can be negotiated by the vehicle to the regions to be circumvented. It may show the area of movement of the vehicle in the form of a subdivision into at least three types of region, namely a first type corresponding to regions to be circumvented, a second type corresponding to bands surrounding the regions to be circumvented and having the width of a maneuvering space arbitrarily considered as necessary for free lateral movement of the vehicle, and a third type of region corresponding to regions of free lateral movement. In the case of an aircraft, said map may be superimposed on the map of a TAWS system in order to specify to the pilot if he has complete freedom of lateral movement or not.Type: GrantFiled: November 30, 2004Date of Patent: February 23, 2010Assignee: ThalesInventors: Elias Bitar, Nicolas Marty

Device for signaling risks, risk level map obtained by the device and method for formulating the map
Patent number: 7633411Abstract: The device relates to the signaling, to the pilot of a craft, of the risks that it incurs due to obstacles placed in its zone of deployment. This device determines, on the zone of deployment of the craft, the contours of several types of risk region as well as the contours of two lateral regions of tight deployment tied to the craft and produces alarms as a function of the types of zones at risk found in the lateral regions of tight deployment.Type: GrantFiled: July 27, 2005Date of Patent: December 15, 2009Assignee: ThalesInventors: Elias Bitar, Nicolas Marty -
Patent number: 7634335Abstract: This method uses for the estimation of a distance, a propagation distance transform considering only the paths which are both accessible to the aircraft taking account of its vertical flight profile and complying with air regulations. The propagated distance Dp is accompanied by a propagated altitude Ap which at all points follows the vertical flight profile of the aircraft, while being greater than the altitudes of these points and complying with the air regulation constraints at these points. This is obtained by subjecting the propagation to compliance with the vertical flight profile of the aircraft, constraints of the elevations of the points of the relief and air regulation constraints.Type: GrantFiled: March 22, 2005Date of Patent: December 15, 2009Assignee: ThalesInventors: Elias Bitar, Nicolas Marty

Patent number: 7587272Abstract: A method of locating difficult access points on a topological map includes: analyzing curvilinear distances using a chamfer mask to catalogue approximate values C(V) of the Euclidean distances separating a point C00 of the map from its nearest neighbors V; determining therefrom, at each point C00 of the map of curvilinear distances, the discrepancies |DT(V)?DT(0)| of curvilinear distances separating the point considered C00 from its nearest neighbors V; comparing these discrepancies with the approximate values C(V); determining the point as a difficult access point based upon a difference between the Euclidean distance and the determined discrepancies of curvilinear distances; and rendering a display of a map indicating difficult to access points.Type: GrantFiled: February 23, 2005Date of Patent: September 8, 2009Assignee: ThalesInventors: Elias Bitar, Nicolas Marty

Patent number: 7583856Abstract: The coefficients of a chamfer mask are, to within a multiplicative scale factor making it possible to give them an integer value, approximations of the Euclidian distances separating the pixels covered by the mask, from the pixel under analysis placed at the center of the mask. As there are at least two possible integer values for each coefficient, the over- and the under-approximation, one is rapidly faced with a considerable number of possible combinations. The method proposed allows progressive selection of the possible integer values, firstly at the level of each coefficient by virtue of an axis error rate criterion, then at the level of the coefficients considered by binomials by virtue of a sector error rate criterion, which considerably reduces the number of combinations to be analyzed to arrive at an optimal combination from the point of view of the error rate obtained in the distance estimations.Type: GrantFiled: October 21, 2004Date of Patent: September 1, 2009Assignee: ThalesInventors: Elias Bitar, Nicolas Marty

Patent number: 7493197Abstract: The parts of the flight plan of an aircraft corresponding to lateral trajectories at low altitude can comprise passages with limited lateral freedom of deployment either because of risks of collision with the ground, or because of risks of penetration into a forbidden overfly zone. The method makes it possible to signal them for the attention of the crew, on the onboard navigation screen, so that said crew should redouble their attention. To do this it uses a detection procedure analogous to that of TAWS ground collision risk warning systems with protection envelopes related to the aircraft, of shapes suitable for the monitoring of the integrity of the spaces necessary for the aircraft to perform flat turns that are as tight as is permitted, while taking account of the local wind.Type: GrantFiled: May 31, 2005Date of Patent: February 17, 2009Assignee: ThalesInventors: Elias Bitar, Nicolas Marty
