    [0001] The present invention relates to a visualization system of an aircraft procedure comprising several alternative sequences of steps, each step comprising at least one operation to be performed, the system comprising: a display; a set of display management on the display, suitable for displaying on the display the successive steps of the procedure. Such a system is intended to be used in a cockpit of the aircraft, to facilitate the work of the crew for the execution of procedures required during the evolution of the aircraft. On the ground, it can also be used by the crew for training in procedures, or for information, for example in an electronic flight organizer or "Electronic Flight Bag". It can also be implemented by a maintenance operator from the cockpit or at a distance from the aircraft.
    [0002] The procedures are for example verification procedures to be implemented before a flight, to verify the proper operation of the various systems of the aircraft, navigation procedures to be implemented during flight, for example during a change phase of flight, or fault procedures to be implemented in case of breakdowns of one or more aircraft equipment. They are for example implemented directly in the cockpit by the crew, or by a remote operator of the aircraft from the ground. Each procedure advantageously comprises a series of operations defined by the manufacturer and / or the operator and validated generally by the certification authorities. These procedures are chained as successive steps comprising one or more operations, or an alternative between a plurality of possible steps. The operations are for example actions to be executed such as commands to an aircraft system, with verification of their application, questions to the crew with a simple expected response, or requests for actions of the crew. Other operations are also purely informative, such as sending messages and / or information to the crew, without expected response. When a procedure is implemented in flight, the crew performs the required actions by operating controls arranged in the cockpit, either directly by switches or by means of computers and software controlled by the crew.
    [0003] 3034860 2 In traditional piloting with a crew of two, a first member of the crew is responsible for short-term pilotage and a second crew member executes successively the various actions provided for in the procedure under the control of the first member of the crew. crew for significant or irreversible actions, such as engine shutdown, fire extinguishing ... The procedures are generally listed in one or more operating manuals of the aircraft, available in paper or electronic form. A large number of procedures are certified and must be strictly applied by the crew, especially in case of breakdowns.
    [0004] On modern aircraft, the procedures are stored as computer files in a database and can be displayed on a cockpit screen when they are to be implemented. Generally, the actions to be performed are successively displayed on a display, the crew having to validate the actions performed as and when they are executed. Some procedures are inherently complex and include several alternative concatenations resulting from discrete steps as a function of choice to be made by the crew, or states of the aircraft systems. In this case, the user may have difficulty in following the procedure, and / or in understanding what stage of the procedure he is at. Known visualization systems make it possible to display successively all the steps of the procedure, but are complex to grasp, given the small size of the display on which the procedure is displayed in a cockpit. For this purpose, the different actions of the procedure are displayed one after the other. On a small-sized display, in the case of an alternative between several steps sequences, the user must first go down the procedure to visualize all the actions to be performed in a first sequence of steps, before reaching the actions to be carried out for the second sequence of steps. This is likely to waste time and affect his understanding of the procedure.
    [0005] The known display systems are therefore unsatisfactory, and difficult to follow for the consultation and the progress of a complex procedure. An object of the invention is to have a visualization system that makes it possible to consult and unfold an airplane procedure in a very simple way, having a good awareness of the past, present and future situation and meeting the requirements of the present invention. reduced size display.
    [0006] For this purpose, the subject of the invention is a system of the aforementioned type, characterized in that the display management unit is capable of displaying on the display an active step of an active sequence of the procedure. at least one preceding step preceding the active step in the active sequence of the procedure and defining an alternative between a plurality of steps and at least one step subsequent to the active step in the active sequence of the procedure, without show a step in the procedure located on a non-active sequence of the procedure that can be accessed from any step prior to the active step. The system according to the invention may comprise one or more of the following characteristics, taken in isolation or in any technically possible combination: each step of the procedure is chosen from an operation to be carried out, a series of operations to be carried out; perform without alternative, access to a sub-procedure or an alternative between several stages. The display management assembly is capable of displaying a linking link between each pair of successive steps displayed on the display, and, when an alternative exists in the procedure between two successive steps, a link of branch signaling a non-active sequence of the procedure. the active step is adapted to be modified by a user and / or by a system 20 of automatic progress of the procedure, the display management assembly being clean, after modification of the active step, to move the old step active on the display to turn it into a new previous step preceding the new active step on the active sequence of the procedure, to move the old step after the old step active on the display to turn it into a new active step and displaying at least one step subsequent to the new active step on the active sequence of the procedure. the active step, the posterior step, and the previous step are displayed along a preferably vertical axis on the display, the display management assembly being able to move the old active step and the old posterior step along the axis, after modification of the active step. the active step is an alternative between two sequences of steps, the modification of the active step consisting in selecting one of the two sequences of steps, the display management assembly being clean, before modifying the active step, to display an alternative link between the sequences of steps, and after modification of the active step, to display at least the selected step, and to hide the step not chosen. The display management assembly is able to display the selected step by enlarging the chosen step, and is able to mask the step not chosen by moving the unselected step off the display. the modification of the active step is obtained by validating the execution of this step during the course of the procedure, the display management unit being able to display a button for validating the active step, which is its own to be operated by a user to validate the active step. - The validation button is adapted to be activated by selection and movement of the button on the display by the user following a predetermined path. The display management assembly is capable of displaying a clean displacement elevator to be actuated in order to display on the display stages prior to the active step on the active sequence. the displacement elevator comprises an indicator of the degree of progress of the procedure in the active sequence of the procedure. At least one step of the procedure suitable for being displayed on the display comprises a plurality of operations to be unwound without branching, the display management assembly being able to display the details of the successive operations to be carried out in the step. the display management assembly is capable of displaying, during a running of at least one operation of the procedure, a signaling cursor of the operation being carried out, and an indicator of achievement of each operation to unroll. the display management assembly is capable of displaying a procedure activation activation button, which can be activated by the user to switch from an activation configuration of the procedure flow, preventing a consultation of the steps; after the procedure to a pausing configuration of the procedure, allowing consultation of the later stages of the procedure. The subject of the invention is also a method of visualizing an aircraft procedure comprising alternating sequences of successive steps, each step comprising at least one operation to be performed, the method comprising the following steps: providing a viewing system as defined above; simultaneous display on the display by the display management unit of an active step of an active sequence of the procedure, of at least one preceding step preceding the active step in the active sequence of the procedure the prior step 35 defining an alternative between a plurality of steps and at least one step subsequent to the active step in the active sequence of the procedure, without displaying a step of the procedure located on a non-active sequence of the procedure that can be accessed from any step prior to the active step. The invention will be better understood on reading the description which will follow, given solely by way of example, and with reference to the appended drawings, in which: FIG. 1 is a view of a block diagram representing an example of a possible sequence of a procedure to be displayed using a display system according to the invention; FIG. 2 is a view similar to FIG. 1, after unfolding of the various sequences; FIG. 3 is a block diagram showing a first display system according to the invention; FIG. 4 is a diagram illustrating the principle of the display of the procedures by means of the display system according to the invention; FIGS. 5 to 7 are views illustrating the display on the display of the system of FIG. 3, when using the system according to the invention in the consultation mode of a procedure; FIGS. 8 to 12 are views illustrating the display on the display of the system of FIG. 3, when using the system according to the invention in the running mode of a procedure; FIG. 13 is a view illustrating the display on a display of the system of FIG. 3 during the implementation of a manual action by the user, and in parallel, the corresponding display on a display of a set of management systems of aircraft, illustrating the control associated with the action to be implemented.
    [0007] In the figures, the display screens are illustrative of real aircraft systems, and are therefore in English, in accordance with the standard display in the aeronautical field. A French translation of the relevant information is given if necessary in the description which follows. A first system 10 of procedural visualization of an aircraft 12 according to the invention is illustrated schematically in FIG. 3. The system 10 is intended to help the crew to implement procedures comprising alternating sequences of steps to 12. Each step comprises at least one operation to be unrolled. Systems 14 include, for example, one or more hydraulic systems 16, one or more electrical systems 18, one or more propulsion systems 20 of the aircraft 12 and / or one or more cab systems 22. This list can be extended to all controlled systems of an aircraft. Each system 14 comprises equipment and components suitable for carrying out hydraulic, electrical, propulsion or conditioning functions of the aircraft 12. In a conventional manner, the aircraft 12 comprises a cockpit 24 occupied by the flight crew. 12. The cockpit 24 comprises at least one table provided with physical control elements and / or a control screen 26 of the systems 14 of the aircraft 12, capable of implementing commands from the systems 14, by the intermediate 10 physical switches or software operated by the crew, or through computer and software driven by the crew. A procedure consists of sequences of operations to be carried out by the crew of the aircraft 12, in particular according to the given operating states of the systems 14 of the aircraft 12.
    [0008] Each procedure is for example implemented on the occurrence of a particular phase of evolution of the aircraft 12, for example taxiing, take-off, the passage of a given altitude, the cruise. Other procedures are implemented on the occurrence of a malfunction or failure of a system 14 of the aircraft 12.
    [0009] In this case, the procedure generally corresponds to a configuration or reconfiguration of one or more pieces of equipment of one or more functional systems 14 of the aircraft 12, by carrying out operations or a sequence of operations, according to the states observed operations of the systems 14 of the aircraft 12. The operations to be carried out advantageously comprise actions to be performed, such as an analysis of a state of a device, a command intended for an aircraft system, with confirmation of the execution of the order, a question to the crew, a request for action of the crew, a monitoring of the actions of the crew, a choice among several possible operations, a bypass of an optional operation, d 'a manual action or action failed to be performed automatically within a given time, adding a new procedure in the list of procedures to play, launching a procedure e and a validation of knowledge of an information by the user. Some operations of the procedure are informative, without validation of the user such as an informative display to the crew, for example the sending of an information message to the crew or the display of one or several parameters related to the procedure.
    [0010] 3034860 7 A command is intended to be transmitted to an aircraft system. Examples of commands are the opening or closing of a valve, the control of electrical switches. An order is generally followed in the procedure of a verification of its application. A question to the crew is generally followed by waiting for a simple answer, for example "yes" or "no". A request for action by the crew is generally followed by an expectation of the action, measured through the effects of the action by means of sensors of the systems 14 of the aircraft 12. A pilot action monitoring is sometimes followed by a confirmation when this action is likely to have significant consequences for the conduct of the flight. The choice among several possible operations, or "alternative" is determined according to the value of information representative of operating states of the systems 14 of the aircraft 12, for example of the state of a valve, of tensions observed, the presence of a fault message or a pilot choice. The choice results in a transition to a series of operations chosen from among several possible series of operations provided for in the procedure, generally between two possible sequences of operations, depending on the current operating states of the aircraft, that is to say operating states that have just been measured and / or pilot choices. A simple display to the crew is sometimes purely informative. In this case, it is followed by no action. The actions are to be performed on a control panel or in a mimic 25 of a screen. The realization of the action and validated by a manual acknowledgment or is detected automatically by a supervision module. Referring to Fig. 1, the procedures are generally specified by detailing the successive list of steps 27A-27E of the procedure, to perform at least one sequence of steps, each step 27A-27E comprising at least one operation to be performed. As indicated above, the procedure comprises at least one step 27B forming an alternative leading to different sequences of steps 27C, 27D, as a function of the current operating states of the systems 14 of the aircraft 12, or responses of the crew with questions to the crew.
    [0011] More generally, each step 27A to 27E of the procedure is formed by a single operation, by a series of operations without alternative forming a macro-operation, by an alternative leading to two sequences of different steps, and / or By access to a subprocedure contained in the procedure Referring to Fig. 3, the display system 10 includes a procedure database 28, receiving the specifications of a plurality of procedures to be performed by the user. crew according to given operating states of the systems 14 of the aircraft 12, a display 30 advantageously to be placed in the cockpit 24 of the aircraft to be accessible to the crew, a set 32 of display management on the display 30, able to display successive steps selected from the procedure on the display 30, and a man-machine interface 34 able to drive the display and / or to validate the display. operations present in the successive stages of the procedure. The human-machine interface 34 comprises for example a touch screen of the display 30 and / or a keyboard and a selection member on the display 30, such as a cursor control or a mouse.
    [0012] Advantageously, the visualization system 10 is connected to a crew assistance system 36 comprising a supervision module 38, able to automatically validate the execution of operations of the steps of the procedure and possibly a module of automatic execution of the operations of certain steps of the procedure.
    [0013] The procedure database 28 contains a description of the procedures, in the form of the characteristics of each of the operations it contains, organized in successive steps, and the successive order of execution of each of the operations, within every step, and steps to steps. It further includes, for procedures including alternatives to several suites of different steps, a definition of the operating states or user choices conditioning the transition to one or the other of the series of steps. The display 30 is for example a screen of the control panel 26 or a window on a screen of the control panel 26. It has the limited dimensions, for example a maximum dimension, taken 30 between the two points furthest from its periphery. , less than 35 cm. The display 30 typically has a height of between 4 cm and 30 cm and a width of between 4 cm and 30 cm. The display management assembly 32 is able to create the display shown on the display 30, and to control the display 30 to display this display in whole or in part.
    [0014] As will be seen below, the display management assembly 32 is able to operate in a consultation mode, in which the user consults the procedure for information purposes on the display 30, without executing the operations of the display units 30. different stages of the procedure.
    [0015] The display management assembly 32 is also adapted to operate in a workflow mode in which the user and / or the control module 40 performs at least part of the operations of the steps of the procedure. user and / or supervision module 38 validating the execution of each operation. According to the invention, the display management assembly 32 is able to display simultaneously on the display 30, an active step on an active sequence of the procedure, at least one previous step preceding the active step on the display. active sequence of the procedure, and at least one step subsequent to the active step on the active sequence of the procedure, without displaying a step of the procedure located on a non-active sequence of the procedure accessible from a step prior to the step 15 active. This is illustrated in FIG. 4, in which the active step is pointed by an arrow 41A and in which the active link 41B is delimited by a closed line. In the consultation mode, the active step pointed by the arrow 41A is a step selected by the user on the display 30 using the man-machine interface 20 34 for example by clicking on the step or by touching the display 30 at the location of the step. In the workflow mode, the active step pointed by the arrow 41A is generally the step of the currently played procedure, in which an operation is running, before the execution of the step is enabled.
    [0016] The active chaining 41B is constituted by the successive active steps selected by the user or executed during the course of the procedure, as well as the step or series of steps immediately following the active step. A non-active sequence 410 of the procedure, accessible from a step prior to the active step, visible in phantom in FIG. 4, groups the steps of a sequence of steps accessible from a step prior to the active step. , but not selected by the user in consultation mode or not played in scrolling mode. With reference to FIG. 1, the display management assembly 32 comprises at least one processor 42 and a memory 44 comprising a plurality of software modules 35 capable of being executed by the processor 42. It furthermore comprises a device 46 of FIG. The processor 42 and the memory 44 are configured for use in the aeronautical field. The memory 44 contains at least one data recovery and data processing module 48, capable of interrogating the database 28 for retrieving and processing the data of at least one procedure chosen by the user, and a module 50 for developing the display on the display 30, able to create the display and transmit it to the display 30 via the device 46 management GUI. The data recovery and processing module 48 is adapted to load, from the database 28, the characteristics of the successive steps of the procedure, in particular the operation or operations to be performed in each step and the links between the steps. . The characteristics of the steps comprise, for example, information that is characteristic of the step, for example the title of the step, the statement to be made, an operation or the definition of an alternative. The characteristics may include additional information from the open world, that is to say outside the certification constraints, and if necessary, information relating to the mandatory nature or otherwise of the execution by the crew of an operation. . When a step comprises a series of operations, the characteristics of the steps include the list of operations to be performed, and the sequence of operations.
    [0017] The recovery and processing module 48 is able to unfold the procedure by duplicating from each alternative of the procedure the common steps 27E to the different steps of the procedure to separate the different branches of the procedure, as is FIG. 2. The processing module 50 is adapted to generate a visible display, for example in FIG. 6, including the active step 70 on the active linking of the procedure, at least one prior step 72 to FIG. active step and at least one step 74, 76 subsequent to the active step 70. The steps 70 to 76 are each displayed in the form of a frame containing the title of the step, and possibly a pictogram 78 representative of the obligation 30 to perform the step by the crew. To maximize readability, steps 70 to 76 are displayed in order of unwinding along an axis AA 'which is vertical in FIG. 6. Thus, each prior step 72 is displayed above the active step 70 and subsequent steps 74, 76 are displayed below the active step 70.
    [0018] Since the active step 70 is an alternative here, the steps 74, 76 which are sequences of possible steps in the active step 70 are displayed under the active step 70, advantageously being positioned next to each other. the other. In a variant, the order of unwinding takes place along a horizontal axis.
    [0019] The processing module 50 is able to mask the steps of the non-active sequences, accessible from each previous step 72 to the active step 70 to facilitate the understanding of the active sequence by the user. The processing module 50 is suitable for placing on the display that it generates linkages 80 between the steps, characterizing the direction of sequence of the 10 steps. Furthermore, according to the invention, and in consultation mode, the processing module 50 is suitable for placing on the display that it generates a connection link 82 signaling a non-active sequence of steps accessible from an earlier step 72, without displaying the steps following this branch link 82 in the non-active sequence.
    [0020] The connection link 82 is advantageously stitched on the linking link 80 connecting the previous step 72 to the active step 70 The elaboration module 50 is able to indicate on the link link 80 and on the link of connection 82 a conditional indication representative of the condition of choice of the corresponding sequence of steps in the alternative.
    [0021] In FIG. 6, the conditional indication is for example "yes" ("yes" in English) or "no" (in English) in response to the alternative defined in the previous step 72 ("FUEL" : ENG1 LO PRESS still active "For" LOW PRESSURE FUEL ALARM ON ENGINE 1 is still active "). Likewise, when the active step 70 is an alternative, the processing module 50 is adapted to place an alternative link 84 between the active step 70 and each of the possible sequence sequences 74, 76, with the conditional indication associated with each sequence of steps 74, 76. The active step 70 is adapted to be modified. In the consultation mode, the active step 70 is modified, for example, when the user selects a new active step, for example the next step 74 in FIG. 6, using the human-machine interface. In the procedure of the procedure, the active step is modified when the active step 70 is validated or acknowledged by the user or by the supervision module 38 to proceed to the next step 74.
    [0022] When the active step 70 is modified, for example by selecting or going to the step 74 shown in FIG. 6, the processing module 50 is able to generate an animation that moves the old display on the display. active step 70 to transform it into a new prior step 92 visible in FIG. 7 and to arrange the new active step 90 resulting from step 74 in FIG. 6 under the new prior step 92. The old active step 70 being a alternatively to choose two suites of steps 74, 76 distinct, the processing module 50 is able to hide the step unselected 76 visible in Figure 6 and to display in Figure 7 a branch link 82, stitched on the chaining link 80 between the active step 90 and the previous step 92. The elaboration module 50 is able to generate an animation between the pre-modification display shown in FIG. 6 and the modified display represents shown in FIG. 7 in which the old active step 70, and the previous step 72 move in translation along the axis AA 'advantageously upwards, and in which the selected step 74 grows and moves towards the axis A-A ', while the step 76 not chosen moves transversely to disappear from the display. Advantageously, when the new active step 90 is displayed, the module 50 is adapted to allow the simultaneous display of all the steps subsequent to the active step 90 until the next step forming an alternative and the sequences of possible steps. after the alternative. Thus, the user has an improved view of the past, present and future situation, while maintaining adequate legibility, even on a reduced size display. Advantageously, the processing module 50 is able to generate a display in which all the previous steps 72 from the point of entry into the procedure to an active step 70 forming an alternative can be accessible. In the case where the number of steps is too large to be displayed in full on the display 30, the processing module 50 is able to insert on the display a lift 94 visible in FIG. along the axis AA 'of displacement. The processing module 50 is able to calculate and display on the elevator 94 a pictogram 95 for locating the steps displayed on the screen, and an indicator 96 for the degree of progress of the active step in the sequence. active procedure, from the beginning of the procedure, until the end of the procedure, choosing a sequence of possible steps, for example the longest possible sequence to the end of the procedure and including the active chaining. The pictogram 95 is for example a closed curve delimiting, on the elevator 94, the displayed steps.
    [0023] The indicator 96 is here formed by a gauge disposed in the elevator. The level of the gauge materializes the steps prior to the active step above the level of the gauge (displayed for example in a first color) and the steps subsequent to the active step below the level of the gauge ( for example in a second color). The indicator 96 allows the user to move quickly to view the previous and / or subsequent steps and then return to the active step by aiming at the level of the gauge. In a variant, not shown, a text is displayed to give the number of remaining steps to unwind in the longest possible sequence of the procedure. The position of the indicator 96 on the elevator 94, here the level of the gauge, is representative of the degree of advance, which allows the user to locate approximately the active step in the sequence of the procedure. In the consultation mode, the visualization is recursive. The user can go back into the active sequence of the procedure and select a sequence of unexplored steps. For this purpose, starting from the new active step 90 on the display of FIG. 7, the user is able to select the step 92 corresponding to the old active step 70, to return to the display of FIG. and then selecting step 76 instead of step 74 In this case, the processing module 50 is adapted to deploy step 76 and to hide step 74. More generally, the production module 50 is able to deploy the frame of an active step to display as part of the active step, the list of operations to be performed at this step. It is adapted to fold the frame on the action of the user, or when the active step is modified, in order to display only the title of the step in the frame. In the unwinding mode, illustrated by FIGS. 8 to 12, the processing module 50 is able to place on the display a cursor 100 identifying the operation being executed in the active step. The cursor 100 is adapted to have a first normal display configuration, in the case where no interaction with the user is needed, as shown in FIG. 10. It is adapted to have a second marked display configuration. , visible in FIG. 11, in the case where user interaction is expected. In the latter case, the slider 100 advantageously has a different color, and / or a visual effect such as a flashing or enlargement / reduction of cyclic size for quick visualization. This blinking can be temporary.
    [0024] The display of the cursor 100 in the latter case can also be combined with that of an interaction button 102 with a user, which can be displayed on the active step and / or on the current operation. step, and to validate the operation and / or to make a choice in an alternative, and optionally with an outer frame 103.
    [0025] The interaction button 102 is for example activatable by selection and then sliding of a user's finger along a given trajectory on the display 30, for example in horizontal translation, when the man-machine interface 34 comprises a touch screen or by click with a cursor moved by a selection member of the human-machine interface 34.
    [0026] The selection of the button 102 and the sliding along a given trajectory prevents the validation of the operation being carried out by mistake by the user, by simply touching the screen. In the run mode, for each operation to be executed, the processing module 50 is able to give a visual indication of the execution level of the operation, for example by means of a color code, and / or to display a symbol 104 of the execution level of the operation. The execution level of the operation is chosen for example from an operation to be executed (the symbol 104 is then an empty square in FIG. 10), an operation executed and validated (the symbol 104 is then a tick symbol on 10, and the operation is colored green), an operation in progress (the symbol 104 is then a waiting clock, not shown, and an unrealized operation because of a failure in the process. (The symbol 104 is then a cross and the operation is colored in amber.) In the case of a running operation requiring execution within a predefined execution time, a time counter remaining Before the end of the predefined execution time is advantageously displayed, an earlier step comprising fully executed operations is also colored green, whereas a step comprising at least one non-executed operation is colored in amber.
    [0027] In the procedure flow mode, the processing module 50 is able to also display a button 108 for activating / deactivating the procedure. The button 108 is activatable in the same manner as the interaction button 102. It is adapted to switch the display management assembly 32 between an active unwind configuration of the procedure, shown in FIG. Figure 11, and a pause configuration, shown in Figure 12.
    [0028] In the pause configuration, or when a breakpoint in the active unwind configuration requiring user validation is reached, the user is able to navigate through steps 74, 76 of the procedure after the active step 70. In this case, the processing module 50 operates for these later stages as in the consultation mode, as can be seen in FIG. 12. The user can also go back in the active sequence to consult the previous steps of the procedure already carried out. It is however unfit to consult the non-active sequences of the procedure accessible from the previous steps 72. The development module 50 displays the links 80 between the steps, without displaying the 10 connection links 82 from the steps 72 prior to the active step 70, as visible in Figure 9. As previously in the consultation mode, the processing module 50 is adapted to insert a lift 94 on the display provided with a level indicator of progress 96 such as described above.
    [0029] The supervision module 38 is connected to the aircraft systems 14 to detect system states and the execution of at least one operation. The automatic execution module 40 is connected to the aircraft systems 14 to send commands for automatic execution of at least one operation, possibly after confirmation of execution by a user of the system.
    [0030] A first display method implementing a display system 10 according to the invention during the consultation of a procedure by a user will now be described, with reference to FIGS. 5 to 7. Initially, the user selects the procedure that he wishes to consult. The loading and processing module 48 queries the database 28 to retrieve the procedure data described above, including the characteristics of the successive steps of the procedure, the operations to be performed within each step and the links between the steps. steps. Optionally, the module 48 unfolds the procedure as shown in FIG. 2 by duplicating at each branch of the procedure the steps common to other branches. Then, as illustrated in FIG. 5, the module 48 generates a display having an initial step 120, an active step 122 forming an alternative and two following steps 124, 126 possible from the alternative that is displayed on the display 30. Each step 122 to 126 is presented in the form of a frame here comprising the name of the step, and possibly a pictogram 78 of the obligation to execute the step by the pilot.
    [0031] Likewise, the processing module 50 generates the display of a simple link 80 between the initial step 120 and the active step 122 and an alternative link 84 between the active step 122 and each Following steps 124, 126. When the user wishes to view a first sequence of steps, he modifies the active step by selecting step 124, by touch screen contact, or by clicking on help from a selection body. In this case, as illustrated in FIG. 6, the step 124 of FIG. 5 becomes the new active step 70 and the old active step 122 of FIG. 5 becomes an earlier step 72. In accordance with the invention, the module of elaboration 50 generates an animation that moves step 124 to center it, increasing the size of its frame. The animation hides the alternate step 126 by laterally moving the step 126 to exit it gradually from the display. The processing module 50 places a linking link 80 between the active step 70 and the previous step 72 and a branch link 82 stitched on the linking link 80, to materialize the presence of a non-concatenation link. active active from the previous step 72 to the following steps 126. This inactive sequence is hidden on the display 30. The active step 70 of Figure 6 is also an alternative. The processing module 50 displays the two subsequent series of possible steps 74, 76 and an alternative link 84 between the active step 70 and the sequences of steps 74, 76. In this case, the subsequent step 76 is a sub procedure. The posterior step 74 is a series of operations to be performed by the pilot, as embodied by the symbol 78.
    [0032] When the user wishes to continue to consult the procedure, he selects, for example, step 74. A new active step 90 is then obtained from the old posterior step 74 by deploying the frame of step 74 and displaying the sequence of operations to be carried out in this new active stage 90.
    [0033] The old active step 70 becomes a new earlier step 92 in Fig. 7 and moves upward along the axis A-A '. As before, the old unselected later step 76 is masked, as well as all the steps following this step 76, which are in a non-active chaining.
    [0034] A chaining link 80 is created between the new previous step 92 and the new active step 90 and a branch link 82 is stitched on the direct link 80.
    [0035] All the steps prior to the active step 90 from the starting point remain present on the display generated by the module 48. However, given the size of the display 30, only part of the previous steps is visible. in the display 30. The non-visible steps of the active chaining remain accessible using a lift 94 5 having a progress indicator 96 as described above. If the user wishes to examine the steps of a non-active concatenation accessible from an earlier step 92, it folds the frame of the active step 90, which again modifies the active step. It then returns to the configuration of FIG. 6, in which the active step is step 70.
    [0036] This then allows him to consult step 76 as previously described. It is also possible to select a branch link 82 to show the sequence of steps associated with this link 82 that become part of the active sequence by masking the non-active sequences accessible from previous steps.
    [0037] A second display method implementing a display system 10 according to the invention, during the course of a procedure, will now be described, with reference to the references of FIGS. 8 to 12. In this example, the procedure is carried out automatically by the control module 40, with the possible obtaining confirmation from the user for certain operations, especially for certain alternatives. The execution of the operations performed is automatically validated by the supervision module 38. Initially, the user activates the start of the procedure using the human machine interface 34, for example by clicking on the button 108 or / and by moving it along a determined path on the touch screen. The button 108 is then displayed by the processing module 50 with a scrolling symbol. The processing module 50 then generates a display as illustrated in FIG. 8, comprising the step 120 of starting the procedure, the step 122 subsequent to the start step 120 and the two succession of steps 124 , 126 alternatives according to step 122.
    [0038] The control module 40 then starts the automatic execution of the operation present at the active step. Initially, before executing the operation, the execution level symbol 104 is an empty square visible in FIG. 8. The execution level symbol 104 successively passes to a waiting clock when executing the execution level. operation, then to a checkmark after execution of the operation and validation of the execution of the operation by the supervision module 38 3034860 18 Similarly, the processing module 50 changes the color of the operation according the execution level, for example to run it in cyan at run time and in green, once the operation has been executed. At the same time, the processing module 50 displays the cursor 100 next to the current operation in the first normal display configuration. Once the initial step has been validated, the active step is modified as shown in FIG. 8. The cursor 100 is moved next to the new active step 122 and the old active step 120 becomes an earlier step. Since the new active step 122 is an alternative requiring a choice, the processing module 50 passes the cursor 100 in the second marked display configuration, and places a frame 103 around the active step. The control module 40 automatically chooses a sequence of steps according to the system states, here the "Leak detection procedure" ("leak detection procedure").
    [0039] The elaboration module 50 again modifies the active step displayed as illustrated in FIG. 9. It passes the old active step 122 in the previous step 128A, performs an animation masking the unselected step sequence 126 and creates an link 80 between the new previous step 128A and the new active step 130A. According to the invention, no step of the procedure located on a non-active sequence of the procedure accessible from an earlier step 128A to the active step is displayed. However, unlike the consultation mode, the procedure is irreversible, except in case of explicit cancellation by the driver of each step back in the procedure. The processing module 50 therefore does not display a connection link 82 on the link links 80 between the steps prior to the active step, but just a conditional indication representative of the choice made (here answer "yes" or yes to the question of the alternative), as visible in Figure 9. The development module 50 also unfolds the active step 130A to display successively all the operations to be performed in this step. Each operation of the procedure is accompanied by an execution level symbol 104 as previously described. The control module 40 then performs the operations to be performed as described above and the processing module 50 modifies the display of the operation accordingly.
    [0040] When an operation can be bypassed manually, the process module 50 places a bypass button (not shown) on the operation, allowing the user to proceed to the next operation by clicking the button or moving the button on the screen. Once the operation sequence of the active step 130A has been carried out, the supervision module 38 validates the step, which allows the passage to a new active step 132 forming an alternative, visible in FIG. must manually choose the sequence of steps 134, 136 to implement. The processing module 50 then displays a frame around the active step 132 and two select buttons 102 to be operated in a first direction to select a first sequence of steps and in a second direction to select a second sequence. steps. The cursor 100 is put in its display configuration marked. As the procedure is suspended at the user's choice, the user can then press the button 108 to deactivate the procedure and consult the subsequent steps of the procedure without performing the operations of these steps.
    [0041] For example, the user selects a sequence of steps 134, among the two sequences of steps 134, 136 possible after the active step 132. The processing module 50 modifies the active step 132, and hides the following steps 136 not selected, as previously described for the consultation mode. With reference to FIG. 12, he places a link 80 between the active step and the previous step and a branch link 82. The user can also navigate the active sequence of steps using the elevator. by being guided in its progression by the degree of progress indicator 96. In a variant illustrated in FIG. 13, when the user must manually perform an operation of the active step, on a piece of equipment of a system 14 of the aircraft 12, the control screen 150 of the system 14 is activated and an indicator 152 is placed on the mimic of the system 14 of the aircraft 12 to signal the operation to be performed. In another variant of the unwinding mode, the user performs partially or completely manually the operations of the successive steps of the procedure without using the control module 40 and / or manually validates the execution of each operation, without using the module of 38. In yet another variant, the system 10 does not have a supervision module 38 and / or a control module 40.
    [0042] In yet another variant, the user is able to select a specific icon in the context of the active step of the procedure, to bring up a window containing the information of the open world. Thanks to the system 10 according to the invention, a user having to carry out complex procedures is able to navigate more easily through the procedure to follow an active sequence, without being disturbed by previous non-active sequences which are nonetheless marked by a branch link 82 in consultation mode. Presenting the later steps as alternatives allows the user to easily view the possible sequence of steps after the active step. In the consultation mode, the user is able to go down in the procedure and on the contrary to go back in the active sequence and to return to the previous alternatives, to explore possibly other possible sequences. The use of an elevator 94 provided with a level of progress indicator 96 further facilitates the perception of the progress of the active step in the procedure. The user therefore has a better awareness of the past, present and future situation. The display system 10 according to the invention is also very useful in a procedure of the procedure, in particular when this procedure is automatic, which makes it easy to locate which stage of the procedure is played. The way of proceeding is irreversible for the past stages, but allows a consultation of the future stages. Thanks in particular to the successive masking of the series of steps not chosen for the alternatives, the display remains both compact and legible, which meets the technical constraints of an aircraft cockpit.
