- SAR Search And Rescue
- the invention can also be applied from maritime buildings for the same type of mission.
- SAR pattern a pattern describing a search path in the English literature and that we will call a SAR trajectory pattern, or simply SAR, thereafter.
- This predefined trajectory aims to optimize the trajectory of the aircraft to cover the entire search area.

- the SAR trajectory patterns are then an integral part of the FMS which supports the tracking by the aircraft of a programmed trajectory.
- a lack of graphical representation in real time the operator enters all the parameters one by one, then this trajectory is inserted into the management of the flight. If visually this does not correspond to the expectation of the operator, the operator must modify the values one by one. This lack of representativeness implies a loss of time for the operator who must re-enter a trajectory if he considers that it is not optimal with respect to the search area;
- the parameters to be entered for the calculation are technical parameters, generally mathematical (position, distance, angles, ...) and are not parameters oriented for a mission (for example to save a pilot who is lost after a crash). This implies a loss of time for the operator who must re-enter a trajectory if he considers that it is not optimal compared to the search area;

- the calculation means comprise, for example, a utility module whose function is to provide the pattern data module with trigonometric calculation primitives in spherical geometry for calculating the position of the points of the patterns in a plane coordinate system.
- Said device comprises, for example, a management module whose function is to interpret the operator interactions detected by the map engine and to request from the pattern data module the modifications of the displayed pattern when an interaction controls the displacement of a control point of said pattern, an update of a pattern displayed on the screen being performed by an interaction of the operator controlling the movement of at least one control point, the map engine providing the management module the new position of said control point, the data module calculating the new positions of the pattern points according to said new position provided by the management module.
- Said device comprises for example a database of maps containing scanned maps representing a geographical area to be displayed, a displayed pattern being superimposed on a geographical area.
- the display means comprise for example means for selecting a pattern, said selection being performed by an interaction between the operator and said display means.
- the calculation of the positions of the points of a pattern is such that the displacement of a first control point produces a translation of the pattern without modification of the other technical parameters of said pattern.
- the calculation of the positions of the points of the pattern is for example such that the displacement of a control point produces a rotation of the pattern around the first control point and modifies the height of the pattern, without modification of the other technical parameters of said pattern.
- the calculation of the positions of the points of the pattern is for example such that the displacement of a control point produces a rotation of the pattern around the first control point and modifies the width of the pattern without modifying the other technical parameters of said pattern.

These patterns define search patterns to be tracked by the aircraft to perform the search. They are used according to the conditions and the nature of the research. These trajectory patterns each have a number of technical parameters that must be set for each mission, starting with the choice of pattern: an extended square pattern 1, a scale pattern 2, a pie pattern, or a pattern 4 tracking, other reasons being possible.
- the technical parameters to be regulated include the following:
- FIG. 2 shows the example of the ladder path pattern 2 where the operator has to define several technical parameters. In particular, he must define the latitude and longitude of the entry point 12 and the exit point 21 of the trajectory 2, as well as the height H, the space E between the "bars" and the total length L of the scale pattern. . All these parameters are entered manually.

- Figures 3b, 3c and 3d represent three successive manipulations on the pattern.
- control point Po has been moved.
- the pattern was then moved without undergoing any shape change, in a translational motion.
- a device may take as input certain parameters of the mission to help the seizure of the pattern and / or propose the best motive suited to the mission. It can also help for updating the pattern during the mission, by playing on its own technical parameters.
- These input parameters are for example the coordinates of a crash zone to be traveled, a last known position of the carrier, a last known traveling speed of the carrier, or the level of fuel remaining on board, and other possible parameters.
- a device may comprise connection means to be connected to avionics buses and on-board sensors, and may therefore:
- the operator's cognitive load is reduced, allowing him to focus on his mission. It does not calculate any change or position of the search path pattern.

- this base 42 may be external to the device, the scanned cards can be downloaded for example;
- a pattern data module 43 able to store and update all the technical parameters relating to the different patterns handled by the operator. For a scale 2 pattern, it stores at least the latitude and longitude of the entry point of the pattern, the latitude and longitude of the exit point, the width and length of the pattern, the orientation angle of the pattern and its number of branches;
- a management module 44 whose function is to recover the interactions of a user or an operator, to interpret them and to request from the module 43 the updating of the data relating to the patterns;
- a utility module 45 whose function is to provide trigonometric calculation primitives in spherical geometry, in order to allow the calculation of the position of all the points of a pattern in a geographical reference, plane, from the knowledge of the technical parameters. pattern (entry and exit points, orientation, shape elements ). These calculation primitives are provided to the pattern data module 43 which integrates the module for calculating the dot positions of the patterns.

- all these components are located in the tablet.
- the screen of the tablet, touch screen type displays the trajectory patterns superimposed on the map background corresponding to the search area.
- the architecture and components of Figure 4 can also be implemented in an onboard mission calculator.
- the HMI is done by means of a screen 40 communicating with this computer, this screen being of the tactile type for example.
- the modification of a pattern can be done via a mouse cursor in the case of using a non-touch media.
- the operator asks to display on the screen a scale 2 pattern on the map, by clicking on the point on the map where the trajectory is to be displayed.
- the map engine 41 determines the actual geographic coordinates of the point designated by the operator;
- the different corresponding interactions are sent by the cartographic engine 41 to the management module 44, these interactions indicating the pattern to be displayed (in scale in this example) and the position of the pattern (latitude, longitude).
- the management module 44 requests the pattern data module 43 to initialize a pattern with the data acquired by the operator's interactions;
- the pattern data module 43 updates its data and asks the map engine 41 to display the pattern, by calling primitives utility module 45 and lists of points;
- the cartographic motor module 41 displays the graph corresponding to the pattern
- the operator performs a "drag and drop" of the control point Po which is at the origin of the motive, the motive to be translated.
- the cartographic module 41 interacts with the operator and retrieves the new point Po;
- the different corresponding interactions are sent by the cartographic engine 41 to the management module 44, specifying the new position Po of the pattern, in latitude and in longitude.
- the management module 44 then requests the pattern data module 43 to modify the pattern with the new point Po passed as a parameter.
- the pattern data module 43 calculates the new points forming the pattern. It can use the utility module 45 for trigonometric calculations. It updates the pattern data and requests the map engine module to display the pattern, by calling primitives and a new list of points;
- the cartographic engine module displays the modified graphic corresponding to the pattern, this pattern being displayed as is until the next interaction on a control point.
- Figures 5a to 5d illustrate the control points for the four exemplary patterns shown in Figure 1.
- Several control points are defined according to the type of pattern as previously indicated. For each pattern, all of its control points allow you to make any possible changes to its technical parameters, changes being made by moving control points.
- Each control point can be manipulated by the operator, for example by a "Drag and Drop" operation on the touch screen of the device.
- Figure 5a shows the control points for the scale 2 pattern, which has four control points:
- Ph its function, by its displacement, to modify the height of the pattern and its orientation, without changing the point of origin Po, the rotation the point Ph is for example placed on the first branch of the pattern, the end opposite the point Po;
- Pn Its function, by its displacement, to modify the width of each branch, and therefore their number.
- the number of branches is equal to the integer part of the result of dividing the width of the pattern by the width of a branch. If necessary, the system adds a last branch to finalize the pattern.
- the point Pn is for example located on one of the branches parallel to the first branch;

- Pn allows to modify the width of each branch, and thus their number. This point is for example located on the last branch of the square before the exit of the trajectory;
- Figure 5c shows the control points for the sector pattern 3:
- Figure 5d shows the points for the tracking pattern 4:
- ⁇ Ph allows to change the height of the pattern and its orientation, without changing the origin point Po (the rotation is around the point Po).
- This point Ph is for example located at the output of the pattern;
- Figures 6a to 6d illustrate the use of control points on the screen of a device according to the invention. More particularly, these figures illustrate the operation of the control points for the scale 2 pattern, the use being identical for all the other reasons.
- the pattern 2 in full lines is in its original position.
- the pattern 2 'in broken lines is the same pattern, but modified as a result of an interaction on one of the control points.
- Pattern 2, 2 ' is superimposed on a map background corresponding to a search area.
- An arrow 60 illustrates the movement of a finger 61 performing "drag-and-drop” or "Drag and Drop" of a control point on the touch screen.
- Figure 6a illustrates the "Drag and Drop” of the control point Po. This displacement produces a translation of the pattern. In this example, the pattern is moved to the right. The orientation and shape of the pattern are preserved.
- Figure 6b illustrates the "Drag and Drop" of the Pw checkpoint. This movement produces an enlargement or a decrease of the pattern as well as its rotation. The origin Po of the motif does not move. The rotation is around this point. In this example, the pattern is enlarged.
- Figure 6c illustrates the "Drag and Drop" of the Ph checkpoint. This displacement produces an enlargement of the pattern in height as well as a rotation. The origin of the Po pattern does not move, rotation is around this point.
- Figure 6d illustrates the "Drag and Drop" of the Pn control point. This movement produces an enlargement or a decrease in the width of the branches, which respectively leads to a decrease or an increase in the number of branches. In this example, the width of the branches has been enlarged and consequently the number of branches has decreased.
- the invention has been described for displaying and updating SAP trajectory patterns. It can be applied for other reasons describing other types of trajectories.
