Abstract: A method for assisting an aeronautical operator in the creation of a flight plan of an aircraft passing through a set of predetermined geographic mission zones includes a step of determination, for each mission zone, of an entry access point and an exit access point of the mission zone, the entry and exit access points associated with a mission zone being able to be separate or merged; and a step of determination of an interzone path from an entry access point to an exit access point of the set of the mission zones which connects, in series and without loop, all the mission zones by their entry and exit access points, and the length of which is minimal.

Abstract: A pattern able to be updated by an operator, the position, the orientation and/or the shape of the trajectory pattern dependent on trajectory parameters, the device comprises at least display means to view the trajectory pattern and the representation of the zone, and means for computing and storing the position data of the pattern and of the representation, the representation comprising a set of control points, the function of a control point being to define at least the value of one of the trajectory parameters, the value being dependent on the movement of the control point, a trajectory pattern modification resulting from an interaction of the operator moving at least one control point.

Abstract: A device comprises display means and means for calculating and memorizing the positions of points forming patterns being capable of being updated by an operator, the position, orientation and the form of a pattern being defined by a set of technical parameters. Each pattern comprises a set of control points, the function of a control point being, by virtue of its movement, to modify at least one technical parameter, a trajectory pattern modification being carried out through an interaction in which the operator moves at least one control point.

Abstract: An aeronautical software application development workbench handling the production of a graphical human-machine interface on one or more display equipment systems comprises computer means processing software tools for creating, simulating or integrating graphical functions or “widgets” and logic functions for modifying the content of the graphical functions according to incoming events on the display equipment system or systems, said widgets being described in a file called “Definition File”. The workbench includes a single graphical editor for designing the user application, the technical characteristic of which is to produce a structured language which describes each widget contained in the definition file and which associates consumed variables called “input plugs” with the modifiable attributes of said widget and produced variables called “output plugs” with the notifications of the events produced by said widget.

Abstract: The field of the invention is that of graphical libraries providing graphical functions used for the drawing of symbologic images. One of the fields of favored application is the generation of symbologic images for the piloting of aircraft. The object of the invention is to propose a method of graphical generation of a colored vector surrounded by a dark contour (H) on a background likewise colored as a single drawing, making it possible to preserve the function of antialiasing. The method uses two different mixing laws dependent on the position of the pixel of the vector with respect to the central axis of the vector. This method presents the following advantages: The calculations are optimized and successive writes to the buffer-memory are avoided; The dark contour is drawn at the same time as the vector of which it forms an integral part and thus becomes a functional state of the vector; The method takes into account the relative priority of the vectors with a single ordering logic.

Abstract: The field of the invention is that of graphics libraries supplying graphics functions used in the tracing of symbolic images. For certain applications, the screen comprises restricted areas, referred to as ‘clipboxes’, inside which no graphics objects must be traced. The method according to the invention allows elementary straight lines to be generated on a matrix display comprising restricted areas without filling the frame-buffer with segments of the straight line belonging to said restricted areas. The method comprises a first step for calculating the segments of the line situated strictly within the allowed area and a second step for tracing said segments in the allowed area.

Abstract: The field of the invention is that of graphical libraries providing graphical functions used for drawing symbologic images. The object of the invention is to replace the rectangular elementary lines with lines having rounded ends so as to eliminate the problems of artifacts which appear when a thick line is represented by a simple rectangle. The invention describes the various steps of the graphical method of generating lines according to the invention in the case involving elementary lines or open or closed broken lines.
