    [0001] FIELD OF THE INVENTION The invention relates to display techniques in the cockpit of an aircraft and details in particular the choice of the centering. BACKGROUND OF THE DISCLOSURE OF A FLIGHT PLAN FOR AIRCRAFT DRIVING OF AN AIRCRAFT of the graphical display area. State of the art Currently, the pilot of an aircraft can choose display zones on the screens of the cockpit display system (CDS) present in the cockpit using the position of the airplane, or a particular point defined as "MRP" (acronym for "Map Reference Point") defining the reference pointpoint (2D point, Latitude / Longitude) of the flight plan.
    [0002] A mode called "SLEW" makes it possible to change the display reference by scrolling the map by "sliding". This current solution of scrolling or sliding display greatly limits the display of information on the screens of the onboard computer because the elements must be around the plane or around a point of the flight plan.
    [0003] Tired manipulations must be made by the pilot if he wishes to have access to other views. These aspects lead to a cognitive overload of the pilot, which is detrimental to his fatigue and therefore to the safety of the flight. There is a need for advanced methods and systems for managing the on-board display of an aircraft or cockpit of a drone.
    [0004] SUMMARY OF THE INVENTION A computer-implemented method for displaying flight information of an aircraft comprising the steps of receiving indication of a selection of a display area is disclosed. any on a screen of an on-board computer of the aircraft; and in response to said indication, reconfiguring the display. The invention as defined overcomes the current inability to select any element of a screen embedded in an aircraft cockpit. The existing systems do not make it possible to select an "arbitrary" zone of a screen embedded in the cockpit but only, for example, predefined points such as waypoints on a map representing the flight path of the aircraft. In concrete terms, the CDS can only focus on the airplane model or on one point of the FMS flight plan positioned particularly on another FMD screen. The term "any" means (as the case may be) "unconstrained" or "non-predefined" or "free" or "freely chosen" or "not limited to predefined choices" or "not imposed by a subordinate information system". underlying ". This term can be omitted (it is not essential). In contrast, free selection according to the invention has multiple implications for display systems and upstream systems connected to display systems. In other words, profound changes must or can be made to the architecture of the information system. In addition to the selection of a point or any element that is freely chosen, various aspects and examples of reconfiguration of the display are presently disclosed. The selection of one or more elements of one or more displays will generally come from the driver but may also result from automatic operations (eg continuous evaluation of the flight situation by the machine, and selection of certain elements without need of rendering 3 associated visual 3021401, etc.). The selection operations may be hybridized, ie partially human and partly machine (for example by means of logic rules). According to one aspect of the invention, the method comprises steps for reconfiguring the display of one or more screens. in the cockpit (or remote control in the case of a drone). The display area may be a surface of the screen (i.e. non-point) or a portion of the screen or even a discrete point of the screen. The selection can be made in different ways, possibly combined. For example, the selection can be made by tactile designation and / or by voice command (e.g. confirmation) and / or by the wheel / mouse / trackpad, etc. In a development, the step of reconfiguring the display comprises one or more geometric transformations of at least a portion of the display, said geometric transformations being selected from displacement, isometry, similarity, affine transformation, a homographic transformation, and / or an inversion. The display area as designated or selected may for example be centered (or recentered) or even reconfigured in a predefined manner. The reconfiguration may comprise one or more geometrical operations (conducted successively or taken in combination) chosen from: a displacement (keeping the distances and angles oriented), an isometry (keeping the distances and the angles), a similarity (keeping the relations distance), an affine transformation (preserving the parallelisms), a homographic transformation (conserving the lines), and an inversion (keeping all the lines and circles in the plane case).
    [0005] In practice, the display may be cropped, enlarged, reduced, zoomed, deformed, recolored, shifted, the contrast adapted, etc., in whole or in part (eg the entire image or only sub-images). parts of image). Zoom values can be static or dynamic. The example driver can control the magnification value or "range" via selectors / rotators to zoom in and out of his ND displays. A reconfiguration may also include one or more bidifferentiable transformations (or diffeomorphisms), conformal or anticonforming transformations (maintaining the angles), equivalent or equiartial transformations (conserving the areas in the plane case), bicontinuous transformations or homeomorphisms (retaining the neighborhoods of points), displacements (reflections, central symmetries, translations, rotations), homotheties, affinities, etc.
    [0006] In one embodiment, the reconfiguration of the display includes a step of "centering" with respect to the selected point or area. In one embodiment, the reconfigured graphic display mode is performed on the so-called ND screen in a mode called "DATA PLAN" for referencing or centering or reconfiguring the active display area 20 (as displayed to the pilot ) with respect to an element designated by the pilot (via the FMD or via the NTD or by means of other equipment present in the cockpit, eg a voice command). In a development, the step of reconfiguring the display consists of centering the display.
    [0007] In one embodiment, the reconfiguration of the display comprises a step of "centering" with respect to a predefined point, previously associated with the preselected point or zone. For example, one of the corners of the screen if it is selected may trigger a dot-centered display representing the current situation of the aircraft, while the selection of another corner of the screen will correspond to the situation of the aircraft. next flight level change. Zones can therefore be defined in association either absolute (i.e. with respect to the screen) or relative (i.e. with respect to the map or MAP). Zones can be delimited by linear or curved boundaries (geographic areas or voxels in the case of 3D). In one embodiment, the display may be centered with respect to another previously defined point, statically in a file or database. The operation of centering the display may be relative to the center of the screen, but not only. In a development, the step of reconfiguring the display consists of reconfiguring the display with respect to a predefined zone associated with the selected zone. For example, the display may be reconfigured with respect to a point near the center, so as to keep displayed a maximum of elements of the flight plan (for example in the displayed range). The reconfiguration can also take as reference point a geographical point different from the one that has been selected (i.e. a predefined zone, previously associated with the predefined zone).
    [0008] In a development, the predefined zone is or corresponds to the selected zone. In the general case, the predefined zone and the selected zone are distinct. In a particular case, there is identity between these two zones. In a particular embodiment, the screen portion or area designated or selected by the driver may be an element of the DUPLICATE page, or an element of the FPLN page, or even a page-related element. Data_x (x = Waypoint, Navaid, Runway, Road) browsing the navigation database (or an element designated by another system, as specified later).
    [0009] In a development, the display area is associated with a third party system to the aircraft. According to one aspect of the invention, the reconfiguration of the display (eg centering) can be done on the basis or foundation of an element from any other system, third to the aircraft, ie not belonging to embedded systems. This embodiment particularizes the fact that any graphic element can be selected. The correspondence between the selected area (portion of the graphic display) and an item from another system (ie, third party) can be accomplished in a number of ways. This correspondence may be established "a priori", i.e. the correspondence is established in a prior manner, or "a posteriori" i.e. after the actual designation. For example, may be displayed on the ND a weather element such as a cloud detected by an on-board weather computer, the radar echo of a nearby aircraft as received by the traffic calculator TCAS, an element geographic as a city displayed by an EFB or a tablet, a field element from a field monitoring computer, etc.
    [0010] In a development, the non-aircraft system is a system selected from a taxi running computer, a ground customer equipment, a maintenance equipment, a terrain and / or traffic monitoring system and / or meteorological system. In the future, several third-party systems are likely to interact with the embedded systems, ie to be accessible via the HMI display interfaces, either by using existing public services or by using existing private services, or finally using new services. For example, it is possible to cite (a) the initialization of the FMS flight plan by an external computer (touch pad or EFB); (b) 7 3021401 integration of the "flight plan" of the FMS with the "taxi plan" of the taxiing calculator (called ANF for Airport Navigation Function, AOF for Airport Onboard Function or TAXI or AMM for Airport Moving Map) ; (c) optimization of the mission, called by a ground client (company tool 5 for example) or edge (tablet, EFB) via FMS calculation requests; (d) updating the FMS software (in particular its 28-day cycle Navigation databases) by third-party equipment (tablet, maintenance tool, EFB); (e) the use of FMS requests by a traffic monitoring system, the weather to filter alerts, or confirm them, or optimize lateral and vertical adjustments (for example for the avoidance of a cloud mass mobile detected by a Weather Radar). The traffic monitoring system is known by the acronym TCAS (Traffic Collision Avoidance System) or Traffic Computer. The field monitoring system is known by the acronym TAWS (Terrain Avoidance Warning System) or GPWS (Ground Proximity Warning System). The weather monitoring system is known by the acronym WxR (Weather Radar); f) the use of FMS requests to assist in triggering events on a third-party system (eg, radio frequency system (RMS) changes when the aircraft approaches a change-over point; g) verification of conformity of the lateral and / or vertical trajectory calculated by the FMS, compared to digitized aeronautical charts provided to the crew (stored in a tablet, an EFB for example); h) the use of the FMS system for predictions over a given time horizon according to defined modes of flight guidance (guidance) and airplane status (for example, the autopilot wishing to know the average climb rate over 2000 feet of altitude evolution with a motor broken down, fuel calculator wishing to compare the average consumption with the consumption FMS predictions ...); i) interactions with the Flight Warning System (FWS) to present verification results, to propose automated DO LIST launches, to directly modify FMS states upon confirmation of faults; j) passengers connected via their cabin interface (IFE for In Flight Entertainment), In a development, the selected area is a revision of the flight plan. This advantageous embodiment allows an evolution of flight plan revision tools. According to this mode, the method comprises a screen reconfiguration step that makes it possible to perform a shortcut for certain functions or to create new functions. The existing "ND 10 PLAN" mode places the MRP in the center of the display. In the present embodiment ("link menu"), a point of the MAP is selected and the list of possible revisions is displayed. After selecting one of the possible revisions, the display is reconfigured around this point.
    [0011] In one development, the method further comprises a step of receiving an instruction to delete and / or insert said flight plan revision. According to this development, the "link menu" can be used to insert the MRP in the flight plan relative to the selected flight plan element (before / after) or to replace the element of the flight plan selected by the MRP. In a development, the step of reconfiguring the display includes applying display rules. The reconfiguration can also be dynamic and / or complex (for example, result from the application of rules). In particular, the rules can resolve possible conflicts in case of instruction collisions between absolute and relative associations (e.g., order of priority of the rules).
    [0012] The reconfiguration of the display may be conditional, e.g. the rules may include tests and / or verifications. The rules can take avionics and / or non-avionics type parameters. For example, the different phases of the flight plan (take-off, cruise or landing), including at a finer granularity, may be associated with different configuration / reconfiguration rules. For example, the display requirements during takeoff are not the same as those during cruise and the display can be reconfigured accordingly.
    [0013] In a development, the method further comprises a step of receiving a deactivation instruction of the reconfiguration of the display. In one embodiment, the reconfiguration of the screen is "disengageable", ie the driver may decide to cancel or disable all the modifications of the current display to return quickly to the "nominal" display mode ie native without said reconfiguration. The output of the reconfiguration mode can for example be done by voice command (passphrase) or via an actuator (deactivation button). Various events can trigger this precipitous output of the current graphic reconfigurations (for example "sequencing" of a waypoint, a change of phase of flight, the detection of a major anomaly such as an engine failure, a depressurization, etc.). development, the selection of the display area is obtained by entering an alphanumeric identifier.
    [0014] According to the invention, it becomes possible to take as point of reference a point other than the position of the aircraft to sort the list of "duplicates". An extended Wildcard search first allows you to enter part of the name of an element. The elements corresponding to this beginning of name are displayed (for example on the ND). The displayed items may correspond to data of the FMS but also to other types of data (possibly merged), for example results from an Internet search or other available network on board the aircraft).
    [0015] In one embodiment, an alphanumeric identifier is selected and then a results list (eg "reference points") is determined by means of this identifier, by comparison with one or more embedded aeronautical element databases, and then optionally displayed. A particular reference point is selected (eg by the pilot). Optionally a list of revisions is proposed. The reconfiguration of the display associated with the selection of the display point (or of a selected revision) is performed. In the details, in one embodiment, a "duplicate" page appears if the list of "reference points" comprises at least two distinct elements. An additional and distinct identifier is attached to each element of the list. The elements of the list, and their additional identifiers, are displayed on the airplane display systems. In a development, the selection of the display portion is performed by touch selection and / or voice control. For example, the 20 selections (and / or subsequent control operations) can be performed by means of graphic cursors, mouse, pad, trackball, joystick, airtouch, motion or gesture detection, haptic sensors, etc. There is disclosed a computer program product, comprising code instructions for performing one or more steps of the method, when said program is run on a computer. There is disclosed a system comprising means for carrying out one or more steps of the method.
    [0016] In a development, the system comprises avionic-type means, for example a Flight Management System and / or a taxi-running calculator (of the "Airport Onboard Function" or "Airport Navigation Function" type). In this embodiment, avionic-type means (i.e. certified and / or regulated by the regulatory authorities) are therefore used. In a development, the system implementing one or more steps of the method comprises non-avionic type means, for example one or more Electronic Flight Bag tablets. In addition, or in substitution, non-avionic means (ie not certified and / or not regulated by the regulatory authorities) are therefore used, for example, the display reconfigurations may in certain cases be deported or switched over to a different location. other types of apparatus, e.g., surrounding EFBs or advanced display means) In a development, the screen or display screens are Human-System Interface screens. In a particular embodiment, the FMS can be used via an AID (Domain Interaction Agent) and / or an integrated IHS (Human-System Interface) which concentrates and organizes exchanges between computers. The screens according to the invention may be the screens of the CDS (Cockpit Display System), i.e. including the screens of the FMS but not only. For the purposes of the invention, the display screen or screens may also comprise one or more screens of the FMS (avionics) and / or one or more EFB screens (possibly non-avionics), as well as screens of third-party systems. In a "unified" perspective of human-machine interfaces, the graphical or visual interface presented to the pilot results from the integration of multiple screens, that is to say from different systems. The acronym IHS underlines this systemic perspective in contrast to the HMI acronym. Instead of compartmentalizing the display or maintaining the partitioning of the interfaces, an integrated display management is possible for future control systems. Therefore, optimizations can be implemented (the information density can be configurable and / or scalable and / or controlled based on rules, etc.). The benefits in cognitive terms can be significant 5 (redundancy or non-information, highlighting certain information, adaptations to the flight context or personal preferences, deactivation of relief etc.). The expression "IHS type screen" thus designates a screen considered according to such future systems, thus implying an additional logic layer (display rearrangement, for example dynamic) compared to the screens of existing systems. In a development, the system comprises, in complement or substitution of the other display means, means (for example display) of augmented and / or virtual reality. These means (for the moment generally considered to be of the "non-avionic" type) include virtual and / or augmented-reality headsets, such as immersive visualization systems (eg head-mounted displays, head-mounted displays, glasses). , projectors, etc.) Advantageously, according to some embodiments of the invention, the pilot reduces his cognitive load. It can corollary to focus on data verification. In particular, the pilot can focus his display on any element of the globe, other than an element of the flight plan (or current plane position). Previously, in order to center the display on a point of the flight plan, it was necessary for the pilot to switch to the "PLAN" display mode in ND ("Navigation Display" screen at the middle of the CDS, displaying the flight plan ), then positions the waypoint on the 2nd line of the FPLN page of its head-down display (MCDU for Multi Purpose Control Unit or FMD for FMS Management Display). This sequence represents a work overload for the pilot and forces him to change the display mode to ND. There is another more recent mode of display, the SLEW mode, which makes it possible to scroll the map by sliding. This mode nevertheless requires knowing the direction of the desired element and is not suitable for displaying a distant element in the flight plan. It does not allow to center the map on any element of the globe. In addition, the FMS system does not provide an easy way for the pilot to control items of the same name having a different position (called DUPLICATE). These elements are currently grouped on a DUPLICATE page of the FMD, and the pilot must search among the elements that corresponds to the one he wishes to use: the pilot is forced to consult a paper or electronic map in order to check the position of the before selecting it. This leaves room for error and overloads the pilot's work. Advantageously, certain described embodiments make it possible to center the display at any point (for example one or more pixels e.g. with a geographical correspondence) which makes it possible to assist the pilot during his interactions with the system. Graphical shortcuts for functions can be created. The driver can graphically display items before using them. The pilot 20 thus decreases its cognitive load, being relieved of tedious verifications, and can focus more on the actual piloting. The present invention will advantageously be implemented in a wide variety of avionic environments, in particular for the presentation of information on board aircraft, on CDS (Cockpit Display System) type HMIs, FMSs, flight control systems, taxi (TAXI), on-board or ground mission systems for piloted or remotely piloted aircraft or drones, EFBs (for Electronic Flight Bag) or tactile tablets. It can also apply to the maritime or road context.
    [0017] DESCRIPTION OF THE FIGURES Various aspects and advantages of the invention will appear in support of the description of a preferred embodiment of the invention, but without limitation, with reference to the figures below: FIG. overall technical environment of the invention; Figure 2 schematically illustrates the structure and functions of a known FMS flight management system; FIGS. 3A and 3B illustrate the operation of the screens of the FMS calculator according to the state of the art; Figure 4 illustrates examples of reconfiguration of the display, according to different embodiments of the invention; Figure 5 illustrates an advantageous display option; Figure 6 illustrates various aspects relating to the HMIs for implementing the method according to the invention.
    [0018] DETAILED DESCRIPTION OF THE INVENTION Certain terms and technical environments are defined below. The acronym or acronym FMS corresponds to the English terminology "Flight Management System" and refers to the flight management systems of the 20 aircraft, known in the state of the art by the international standard ARINC 702. During the preparation of a flight or during a diversion, the crew proceeds to enter various information relating to the progress of the flight, typically using a flight management device of an aircraft FMS. An FMS comprises input means and display means, as well as calculation means. An operator, for example the pilot or co-pilot, can enter information 3021401 such as RTAs, or "waypoints", associated with waypoints, that is, points at the same time. from which the aircraft must pass. These elements are known in the state of the art by the international standard ARINC 424. The calculation means make it possible in particular to calculate, from the flight plan comprising the list of waypoints, the trajectory of the aircraft, according to geometry between waypoints and / or altitude and speed conditions. In the remainder of the document, the acronym FMD is used to designate the textual display of the FMS present in the cockpit, which is generally arranged at a low head (at the pilot's knees). The FMD is organized into "pages" which are functional groupings of consistent information. Among these pages are the page "FPLN" which presents the list of the elements of the flight plan (waypoints, markers, pseudo waypoints) and the page "DUPLICATE" which presents the results of the 15 searches in navigation database. The acronym ND is used to designate the graphical display of the FMS present in the cockpit, usually arranged in the middle head, in front of the face. This display is defined by a reference point (centered or bottom of the display) and a range, defining the size of the display area. The acronym HMI stands for Human Machine Interface (HMI). The entry of information, and the display of information entered or calculated by the display means, constitute such a man-machine interface. With known FMS devices, when the operator enters a waypoint, he does so via a dedicated display displayed by the display means. This display may optionally also display information relating to the time situation of the aircraft vis-à-vis the waypoint considered. The operator can then enter and display a time constraint set for this waypoint. In general, the HMI means allow the entry and consultation of flight plan information. Figure 1 illustrates the overall technical environment of the invention. Avionics equipment or airport means 100 (for example a control tower in connection with the air traffic control systems) are in communication with an aircraft 110. An aircraft is a means of transport capable of evolving within the atmosphere earthly. For example, an aircraft can be an airplane or a helicopter (or even a drone.) The aircraft comprises a cockpit or a cockpit 120. Within the cockpit are flying equipment 121 (called avionic equipment), comprising, for example, one or more on-board computers (means for calculating, storing and storing data), including an FMS, means for displaying or displaying and for inputting data, communication means, as well as ( possibly) haptic feedback means and a running computer A touch pad or an EFB 122 can be on board, portable or integrated in the cockpit, said EFB can interact (two-way communication 123) with the avionics equipment 121.
    [0019] The EFB may also be in communication 124 with external computing resources, accessible by the network (eg cloud computing or "cloud computing" 125. In particular, calculations may be done locally on the EFB or in the calculation means accessible by the network, the on-board equipment 121 is generally certified and regulated while the EFB 122 and the connected computer means 125 are generally not (or to a lesser extent). architecture allows to inject flexibility on the side of the EFB 122 while ensuring a controlled security on the side of the avionics avion 121.
    [0020] 17 3021401 Among the equipment on board are various screens. The ND screens (graphic display associated with the FMS) are generally arranged in the primary field of view, in "average head", while the FMD are positioned in "head down". All the information entered or calculated by the FMS is grouped on pages called FMD. Existing systems can navigate from page to page, but the size of the screens and the need not to put too much information on a page for its readability do not allow to comprehend in their entirety the current and future situation of the flight of synthetic way. The 10 crews of modern aircrafts in cabin are usually two people, distributed on each side of the cabin: a "pilot" side and a "co-pilot" side. Business aircraft sometimes have only one pilot, and some older aircraft or military transport have a crew of three. Each one visualizes on his IHM the pages that interest him.
    [0021] 15 Two pages of the hundred or so possible are usually displayed permanently during the execution of the mission: the page "flight plan" first, which contains the route information followed by the aircraft (list of the next points of departure). passage with their associated predictions in distance, time, altitude, speed, fuel, wind). The route is divided into 20 procedures, themselves consisting of points (as described in patent FR2910678) and the "performance" page, which contains the parameters useful for guiding the aircraft on the short term (speed to follow, ceilings d altitude, next changes of altitude). There are also a multitude of other pages available on board (the pages of 25 side and vertical revisions, information pages, pages specific to certain aircraft), or generally a hundred pages. The large number of pages available sometimes makes it difficult to access information.
    [0022] Figure 2 schematically illustrates the structure and functions of a known FMS flight management system. An FMS 200 type system disposed in the cockpit 120 and the avionics means 121 has a man-machine interface 220 comprising input means, for example formed by a keyboard, and display means, for example formed by a display screen, or simply a touch display screen, and at least the following functions: - Navigation (LOCNAV) 201, to perform the optimal location of the aircraft according to the geolocation means such as the satellite positioning or GPS, GALILEO, VHF radionavigation beacons, inertial units. This module communicates with the aforementioned geolocation devices; - Flight Plan (FPLN) 202, to capture the geographical elements constituting the "skeleton" of the route to be followed, such as the points imposed by the departure and arrival procedures, the waypoints, the air corridors, commonly referred to as "airways" according to English terminology. The disclosed methods and systems affect or concern this portion of the calculator. An FMS generally hosts several flight plans (the so-called "Active" flight plan on which the aircraft is guided, the "temporary" flight plan 20 allowing modifications to be made without activating the guidance on this flight plan and "Inactive" flight plans of work (so-called "secondary") - Navigation Database (NAVDB) 203, for constructing geographical routes and procedures from data included in the bases relating to points, beacons, interception or altitude legacy, etc. - Performance database, (PERFDB) 204, containing the aerodynamic and engine parameters of the aircraft; 19 3021401 - Lateral Trajectory (TRAJ) 205, to construct a continuous trajectory at from the points of the flight plan, respecting the performance of the aircraft and the confinement constraints (RNAV for Area Navigation or RNP for Required Navigation Performance); 5 - Predictions (PRED) 206, to build an optimized vertical profile on the trajecto Laterally and vertically, giving the estimates of distance, time, altitude, speed, fuel and wind, in particular at each point, at each change of pilot parameter and at destination, which will be displayed to the crew. The disclosed methods and systems affect or affect this portion of the calculator. - Guidance (GUID) 207, to guide the aircraft in its lateral and vertical planes on its three-dimensional trajectory, while optimizing its speed, using the information calculated by the Predictions function 206. In an aircraft equipped with a device autopilot 210, the latter 15 can exchange information with the guide module 207; - Digital data link (DATALINK) 208 for exchanging flight information between flight plan / prediction functions and control centers or other aircraft 209. - one or more HMI screens 220. All information entered 20 or calculated by the FMS is grouped on screens of displays (pages FMD, NTD and PFD, HUD or other). FIGS. 3A and 3B illustrate the operation of the screens of the FMS calculator according to the state of the art. As a reminder, in current systems, the display can only be reconfigured with respect to a waypoint. This reference point corresponds to the position of the aircraft itself or to a point selected from the other waypoints of the FMS flight plan. No other point can be directly selected in the state of the art.
    [0023] FIG. 3A shows the screen of a current FMS (for example an ND screen) in "ROSE" mode 300: in the example presented, the model is centered on the airplane and oriented according to the aircraft heading (FIG. airplane 301 is in the middle of the screen). When moving the aircraft, the display remains centered on the aircraft. An alternative view called "ARC" makes it possible to visualize what comes in front of the aircraft (semicircle, always centered on the plane). Figure 3B shows the same screen existing in "SLEW" mode 310: the screen is oriented in North / East and can be manually shifted (here by application via a touch interface) from a position 321 10 to 322 by the pilot. ND's SLEW mode also allows you to change the display reference by scrolling the map. This SLEW mode nevertheless requires knowing the direction of the sought-after element. It is not suitable for displaying a distant element in the flight plan. The "SLEW" mode is a particularization of the "PLAN" mode also oriented North / East and centered on the point corresponding to the second line of the FMD page "FPLN". FIG. 4 illustrates examples of reconfiguration of the display, according to various embodiments of the invention. In a context 401 (flight plan revision) or 402 (pilot information search), after the determination 410 of a so-called MRP point, the display is reconfigured 430 according to options 440. The point MRP ( "Reference point" or "Map Reference Point") according to the invention may correspond to a waypoint 411 of the flight plan, but not only. Any point 412 displayed on the map (or generally on the flight displays), or else manually created for example by means of a click on the screen, may be selected. Different elements can be selected from the FMD or NTD to define this MRP.
    [0024] The driver can access the options for reconfiguring the display in several ways, several examples of which are described below. Several contexts of access or arrival in the mode of (reconfiguration of) the visualization of the flight plan according to the invention are 5 possible. A first context 401 corresponds for example to the revision of a flight plan (e.g. modification of the flight plan in the aeronautical context, for example according to AEEC ARINC 702). In this example, the flight plan concerned is displayed and any point of the flight plan can be selected. A second context 402 making it possible to access the visualization according to the invention can be called "Search" and corresponds to a search for information on the part of the pilot (for example a "data_Waypoint, data_Navaids or Data_Airport" page) or according to a new page dedicated to the FMS). For example, the data to be searched for can be those included in the international standard AEEC ARINC # 424 (waypoints, procedures, airports, radio navigation beacons, ...), but more generally, the search function can be applied to any element present in a database.
    [0025] In this context, according to a particular embodiment, a menu may allow the pilot to specify the name of the flight plan to display, flight plan that can be used during interactions with the system. The system can then propose a default flight plan or the pilot can choose another flight plan of his choice in at least one dedicated selection area.
    [0026] The choice of the default flight plan can for example be stored in CMI. The last value selected by the driver can also be used for the next run in the new "Data Plan" mode or in a "Search" mode. Different flight plans can be selected (for example via radio buttons) 22 3021401 In the detail of another possible implementation, the "current" MRP and the various other waypoints can be displayed line by line on the FPLN page of the FMD . The pilot, by scrolling the flight plan information on the text display, can select a new MRP and thus center the display around this new choice. For example, by placing the 10th point of the flight plan on the 2nd line of the FPLN, the pilot centers the graphical display on this point, which makes it possible to visualize his environment (trajectory around this point and / or elements like the airports, navigation beacons, etc ...).
    [0027] In the "search" mode, a particular management of the duplicates is described below. To revise the flight plan or in other contexts, items in the navigation database (such as waypoints, tags, or airports) may be searched by the pilot. The latter then enters all the letters of the searched element (according to the state of the art). It then frequently happens that the name entered by the driver corresponds to several distinct elements of the database (the names are limited to 5 characters). In this case, the FMS displays the DUPLICATE page by listing the names of the elements (names that are all identical) as well as the position of each of them in the form of a textual Latitude / Longitude. The elements are sorted in ascending order of distance to the aircraft, with the nearest elements being displayed above the farthest elements. The driver is then in charge of selecting the element so that the system finishes the revision if necessary. In other words, the structuring of the database and the search mode can lead to the appearance of many duplicates, so that when the pilot wants to change the current display, many manual operations are required ( for example, the centering of the ND display on a point of the flight plan requires the pilot to switch to PLAN display mode to ND, to insert this waypoint in one of the flight plans, and to position this waypoint on the 2nd line of the FPLN page of the FMD, in 23 3021401 having, if necessary, selected the waypoint among duplicates after a search by "Wildcard" if necessary). The current FMS system does not provide the means for the pilot to check that the item he will select in the "DUPLICATE" list corresponds to the one he wishes to use: the pilot is compelled to consult a paper or electronic card to check the position of the item before selecting it on the DUPLICATE page. This leaves room for error and overloads the driver. Sorting by increasing distance from the elements to the aircraft may also be inadequate, the element sought by the pilot may be several hundred nautical miles (modification of the end of the flight plan, near the destination, for a transoceanic flight plan for example). The full name of an element is not enough to remove all ambiguities. It is generally only after the revision has been completed that the pilot can control graphically that he is not mistaken. Wildcard extended search allows the pilot to enter only part of the name of an item. The possible options are: a) no special character use requiring extended search, the extended aspect applies to all searches. Entering a sequence of characters searches for all items that begin with these characters, end with these characters or contain this character string (configurable options); b) an extended search specified by the driver when using a special character in the name. The special character can be placed at the beginning, middle or end of characters entered by the pilot. He can also use the special character several times. On the other hand, if this special character does not appear in what has been entered by the pilot, only the elements whose name is exactly the same as that entered by the pilot will be part of the result of the search. The choice of search type can be parameterized, and the preferred choice stored in a configuration file at startup.
    [0028] In one embodiment, the pilot may select one or more reference points, other than the position of the aircraft, to sort the list of duplicates. The pilot for example can choose his sorting option by means of a dedicated menu, the chosen point and its position appear on the DUPLICATE page. Different options are possible, these options being selectable by the pilot and the system offering a preferred default setting stored in CMI: aircraft position, destination airport, MRP, the center point of the new Data_Plan mode when it is active. The driver may also request to center the ND in Data_Plan mode with this reference point, using a graphical means (for example, a button). A wide variety of options associated with the reconfiguration of the display 440 are possible, in particular by searching "Wildcard", by means of graphic indicators, by specifying the "range" options (zoom values, etc.). Different improvement options for the "range" (e.g. zoom values) can indeed be defined by prior configuration of different values. In a "DATA_Plan" mode, the driver can select as MRP an element displayed on the FMD from the following elements: (a) an element 20 of the DUPLICATE page, allowing the pilot to verify that it is the correct element ( by visual inspection of the point in relation to the flight plan trajectory or other element displayed on the ND). For example, the pilot selects the element by clicking or designating a graphical interface means associated with the element (in the example below, by clicking or by passing the pointer over the Lat / Long coordinates of the point in question). ). This preselection can have the effect of centering the element to the ND by using a dedicated symbol and identifying in the list of the DUPLICATE page the element by another graphic means (for example, changing the color of the font, the background of the name); (b) a flight plan element on the FPLN page to center it at the NTD. This 3021401 makes it possible to modify the flight plan and / or the trajectory since the graphic mode. Acting as a shortcut, in 2 clicks the waypoint is placed at the center of the ND without placing the waypoint in line 2 of the FPLN page and without changing the display mode of the ND; (c) an element of the navigation data base during a consultation (Data_x pages, where x is a Waypoint, Navaid, Runway, AAR route or Drop Pattern). The pilot can thus use this element on the ND and access a contextual menu allowing the modification of the flight plan, the trajectory or the pilot database (OMD) without inserting the element in a flight plan.
    [0029] According to another example of access to the reconfiguration of the display, the driver can also select one or more elements on the ND to open the "Data_Plan" mode among (i) a data option (mode of presentation to the ND of elements of the navigation database such as waypoints, airports, radio navigation beacons); (ii) a point on the flight plan and (iii) the position where the pilot clicked on the ND (the system then creates a point called "pilot point" 412 whose coordinates correspond to the location of the click or the tactile designation on the map). It is emphasized that any area of the display (in the overall sense) can be selected. In addition to the predefined points or areas, the pilot can interact with one or more points of his choice. An element can therefore be "created" manually e.g. "on the fly" by the pilot (for example by a mouse click or a manual designation of a touch screen area).
    [0030] In particular, an element corresponding to an element from another system can be selected. This correspondence between the portion of the graphic display can be established "a priori", i.e. the correspondence is established beforehand, or "a posteriori" i.e. after the actual designation. As an example, a weather element such as a cloud detected by an on-board weather computer, the radar echo of a nearby aircraft as received by the traffic calculator TCAS, can be displayed on the ND. geographical element such as a city displayed by an EFB or a tablet, a field element derived from a field monitoring calculator, etc. Figure 5 illustrates an advantageous display option. In some cases, items of interest may be outside the display frame. Graphical indicators such as arrows 521, 522 or 523 (and others) can provide the direction (and distance, for example, displayed under arrow 523, or symbolized by a smaller arrow size 522) of these elements. off the display. In other words, the waypoints that are outside the display area of the ND can be materialized by graphic indications. A graphical indication is used to give the direction of the one or more elements that do not appear on the display. In order not to overload the display, the indication may appear every 45 ° (other values are possible). In one embodiment, when the pilot selects (for example by touching the screen) one of these indications, the list of points concerned or a series of options may be displayed. Still using the touch interface, removing the finger or confirming the current selection, the driver can center the display on the selected point. In one example, when the pilot selects an indication (for example the arrow "SOUTH" 523), the list of waypoints that are in that direction appears.
    [0031] Another option (not shown) is to establish a context menu ("link"). The "Data_Plan" mode introduces the possibility of referencing two graphical elements to the ND: 1) the reference point MRP (in the center of the ND) and 2) an element displayed on the map (MAP). This allows to open a contextual menu ("link menu") of revisions between 27 3021401 these two elements. This is a shortcut for some functions. The element selected by the pilot may be a point in the flight plan or an element of the displayed "data options" or Latitude / Longitude information corresponding to the location on the MAP where the pilot clicked, or again a element provided by another system. In a very particular case, the centering point or MRP selected may correspond to an element coming from a system other than the FMS, this point being able to be used to interact with the FMS. Other advanced features (not shown) can be implemented. A new interaction to enter the report points ATC (called FIX INFOS) can in particular to center the "Reference Point" of a FIX_INFO, and thus to test several radial and several distances. A graphic means (for example by means of a gray button with the "LOCATE" label) can make it possible to request to switch to "DATA_Plan" mode centered on the Waypoint REF of the FIX_INFO function. According to another advanced option, the reference airports of the "Equi-Time Point" function can also be selected by the pilot to implement the "DATA_Plan" mode. According to another advanced option, the link menu can be used to insert the MRP in the flight plan relative to the selected flight plan element (before / after) or to replace the element of the selected flight plan by the MRP. Finally, a "What If" option can help to make the decision by centering the display on a point of interest in order to check the weather map, the air traffic, the availability of airport services before insertion into the plan. Figure 6 illustrates various aspects relating to the HMIs for implementing the method according to the invention In addition to - or as a substitute for - the screens of the onboard computer FMS and / or EFB, additional HMI means can be used. , the FMS 30 avionics systems (which are systems certified by the air regulator and which may have certain limitations in terms of display and / or ergonomics) may be advantageously complemented by non-avionic means, in particular HMIs. In particular, said man-machine interfaces can make use of 5 headsets of virtual reality and / or augmented.The figure shows a headset of reality vi Opaque 610 (or a semi-transparent augmented reality headset or a configurable transparency headset) worn by the pilot. The individual display headset 610 may be a virtual reality headset (RV or VR), or augmented reality headset (RA 10 or AR) or a high aim, etc. The helmet can be a "head-mounted display", a "wearable computer", "glasses" or a headset. The headset may comprise calculation and communication means 611, projection means 612, audio acquisition means 613 and video projection and / or video acquisition means 614 (for example, use for scraping). data accessible analogically from the cockpit or cockpit of the aircraft). In this way, the pilot can - for example by means of voice commands - configure the visualization of the flight plan in three dimensions (3D).
    [0032] FIG. 6 represents such an example of 3D visualization of a flight plan, as accessible to the pilot by means of the helmet 610. The position of the aircraft in progress is indicated by the dot marked 601. Various intermediate waypoints are represented and the final destination point is marked 602. By means of suitable interfaces the pilot can determine one or more viewing perspectives represented for example by the cones 621 and 622. In a 2D embodiment, the pilot can reconfigure the display (eg recenter) from any point in the space. In a 3D embodiment, the driver may reconfigure the display (e.g., determine the perspective represented by a solid angle) from any point in space 630 (e.g., freely selected).
    [0033] 29 3021401 The information displayed in the 610 helmet can be entirely virtual (displayed in the individual helmet), entirely real (for example projected on the flat surfaces available in the real environment of the cockpit) or a combination of both (in part 5 a virtual display superimposed or merged with reality and partly a real display via projectors). The display can also be characterized by applying predefined placement rules and display rules. For example, human-machine interfaces (or information) may be "distributed" (segmented into distinct, possibly partially redundant, then distributed) portions between the different virtual (e.g., 610) or real (e.g. FMS, TAXI) screens. The different steps of the method can be implemented in whole or in part on the FMS and / or on one or more EFBs. In a particular embodiment, all the information is displayed on the screens of the single FMS. In another embodiment, the information associated with the steps of the method are displayed on the only embedded EFBs. Finally, in another embodiment, the screens of the FMS and an EFB can be used together, for example by "distributing" the information on the different screens of the different devices. Proper spatial distribution of information can help to reduce the driver's cognitive load and thereby improve decision-making and increase flight safety. The present invention can be implemented from hardware and / or software elements. It may be available as a computer program product on a computer readable medium. The support can be electronic, magnetic, optical or electromagnetic. The means or computing resources can be distributed ("Cloud computing"). 30
