Definitions
- the present invention relates to the field of avionics and more particularly to the definition of the management of aircraft flight plans and their context.
- Flight plans are used to calculate the trajectories followed by the aircraft, and allow the various operators (pilot, air traffic controller, etc.) to assess, in advance, the path that will be followed by the aircraft. Flight plans are generally defined by a succession of waypoints, each waypoint being generally associated with a passage time and an altitude.
- the pilot of an aircraft has a display of the flight plan, allowing him to view the current flight plan context including the flight plan and the environment such as weather, NOTAMs, traffic, airspaces, etc., but also to modify it.

- One of the objectives of the invention is to synchronize, in real time, the first and second sets of objects, in order to allow the operators of the different systems to view, in real time, the same flight plan and the same objects, while doing independent work of processing sets of objects.
- the systems 1000 and 1100 exchange messages, via their communication ports 1030, 1130.

- the invention makes it possible to synchronize the representation of the flight plan and the surrounding objects between the system 1000 and the system 1200. In fact, changes made on one side are propagated to the other.
- This makes it possible to create a collaborative workspace, in which the different operators, for example a pilot and an air operations controller, can interact in real time.
- This is referred to as a deterministic dynamic flight plan context, because the flight plan and its context are dynamically shared between all the systems collaborating on the flight plan. It is also deterministic in the sense that it is uninterpretable.
- a response message is returned with a status indicating either rejection of the change or, when the change is accepted, a resend of the change. same modification, or subsequent modifications. This way, the sender of a change can check whether the change was applied identically, or involved subsequent changes.
- the invention also makes it possible to guarantee better air safety, since the various operators have up-to-date information at all times and in real time.

- a modification of the flight plan can be initiated by the flight management system 1050. It is then transmitted to at least one computing unit 1040, and integrated into the graphic interface.
- an avionics-initiated flight plan modification does not need to be validated by the operator of System 1000: it can be transmitted directly to System 1100.
- changes to the flight plan in the collaborative interface can be sent to the avionics, as soon as they are validated at both the system 1000 and system 1100 level, or manually at the request of the system operator. 1000.
- Figure 2 shows an example of a graphical interface in one embodiment of the invention.
- the graphical interface 200 can be used by both the first system 1000 and the second system 1100. It represents all the objects in the workspace.
- the set of objects in the environment of the flight plan 210 defined in particular by waypoints 211, 212, and 213, include:
- - zones defined along the flight plan o a GPS 220 service interruption prediction zone; a turbulence prediction zone 221;
- a change of speed 230 (change to Mach 79); o a creation or a change of offset (lateral shift) of trajectory at a point 231, o a climb towards a new FL at a point 213; o a point of no return to the departure aerodrome 240; o a point equidistant or equi-time between the departure and arrival aerodromes 241;
- An inactive flight plan section that does not belong to the active flight plan.
- the same graphical interface is displayed on each of the systems, and allows each of the operators to have the same view of the modified flight plan and of its environment for this mission. Indeed, the ground operators can see several missions but for a given mission, the flight plan and the interface are the same as those of the flight in question. This thus allows smoother interaction between the various operators, in particular between the pilots and the operators on the ground.
- the graphical interface 200 can be executed, in the form of a specific module, by the computing units 1040, 1140 can execute, in connection with the display devices 1010, 1110, and the input interfaces 1020, 1120 respectively.
- operators can zoom, shift the view, but also interact with it, including modifying the flight plan, adding objects or validating objects added by other operators.
- the graphical interface 200 allows the definition of characteristics of objects, and their placement on the map. It also allows you to view their insertion, and send them to other systems using the shared interface.
- Each of the objects can be defined using an attribute library, including among others: a type, a label, a text, and a function.
- the shape and position of an object can be defined in several ways. For example, they can be defined graphically on the mission interface, in the form of a succession of points, or by entering parameters in textual form.
- Figure 3 shows several exemplary objects of a graphical interface in a set of embodiments of the invention.
- the objects exchanged by the messages can, according to different embodiments of the invention, belong to different categories.
- revisions of the flight plan can be the addition or deletion of one or more points, procedure (s), section (s) of FPL.
- revisions dynamically update the flight plan.
- revision 310 consists of a “DirectTo” type flight plan revision instruction instructing the aircraft to go directly to waypoint WPT2, without going through waypoint WPT1. If this change is accepted, the initial flight plan 311, including waypoint WPT 1, then waypoint WPT2, becomes flight plan 312, in which the aircraft proceeds directly to waypoint WPT2, at starting from a geographical starting point (latitude / longitude) TP which is also shared between the ground and the edge.
- These revisions can come from navigation applications or from the 1040 flight management system and can include: o usual navigation functions, such as the Direct To, offset, add, delete point (s) functions , waiting pattern, procedure (s) ...; o updates to parts of flight plans.
- a flight plan review can be initiated by an operator on one of the interfaces 1020, 1120, or by the flight management system 1040.
- objects can also be of one of the following types:
- pseudo point defined as another type of point created by the operator or the system that can be fixed or moving along the flight plan, different from a fixed waypoint from a database;
- any graphic object that can be inserted into a navigation interface can be used by the invention, whether it is of a purely informative or graphic nature (example: a text zone), or whether it contains information likely to interact with the reference flight plan (example: a closed surface representing a meteorological danger zone.
- flight plan is a function directly applicable in the flight plan management function within the meaning of the state of the art of the navigation functions of an FMS flight management system, for example the erasure of a point , the activation of a Direct To, the insertion of a vertical rise step ...
- - a type defines the type of graphic objects: point, area ...;
- a position this can be defined in different ways, for example by geographic coordinates, or a relative position on the flight plan;
- a function defining an interaction with the flight plan for example, an area crossed by the flight plan generates a function such as an offset (lateral shift).
- a system can be used to view multiple different flight plans, of multiple aircraft.
- an air traffic control system can alternately display several different flight plans corresponding to different aircraft with which the air traffic controller can communicate.
- the objects to be displayed can be more or less relevant depending on the flight plan considered: objects can be defined, in general, at a location regardless of the flight plan considered. For example, a closed surface indicating a storm is a relevant object regardless of the flight plan or the aircraft considered. We will then speak of a universal object, displayed regardless of the flight plan considered on the CCS side.
- the universal objects are displayed regardless of the flight plan studied, and the specific objects only. when the flight plan to which it is associated is displayed. This allows for example an operator of the operational control center to change flight plan to collaborate with different aircraft, while having a set of universal objects permanently visible.
- An object of type "text zone” can place a text providing an indication to the other operators. For example, a text “NO ENTRY FL 200 FL 400" indicates that an area is no-fly between FL 200 and 400.
- Symbol type objects can be defined from a library of symbols common to the different systems, each symbol being defined by an identifier in the library.
- the symbol 320 represents orographic waves (or "mountain waves" in English) and can be inserted by one of the operators at any place in the work area that can be associated with a geographical area.
- the use of a common symbol base allows the interactive addition of symbols immediately understandable by all operators, allowing even smoother interaction between the different operators.
- Closed areas can be defined by a set of geographic positions defining a geometric shape, delimited by an outline, a fill meeting a criterion associated with the object and a label.
- the hatched area of Zone 330 defines a meteorological hazard.
- An object of the "enhancement” type defines a geometric figure arranged around an object of the interface. This figure can in particular be defined by a shape, a color and a thickness, in order to highlight an element represented on the interface.
- objects 340 and 341 respectively highlight waypoints "SIROD", and an "LSTR" airport, to signify that LSTR airport is a preferred diversionary airport.
- flight plan section 350 defines a flight plan section between waypoints WPTA, WPTB, and the ARPTI airport.
- a “pseudo point” type object represents a pseudo point on the flight plan, that is to say a point on the flight plan that does not involve any modification or revision of the flight plan. this one. For example, it could be an informative point.
- the pseudo-point 360 associated with the label “PNR” (Point of No Return), indicates a point on the flight plan from which the aircraft can no longer make a U-turn to reach the departure aerodrome. with minimum fuel on board.
- FIG. 4 represents a first example of creation of derived objects, before and after revision of a flight plan, in a set of embodiments of the invention.
- the interaction of certain objects with the dynamic flight plan induces the creation of other objects, which may be called derived objects.
- At least one computing unit is configured for:
- This new object is a derived object.
- each system according to the invention can permanently update a list of original objects, and derived objects, and iteratively add or delete derived objects, when the modifications of the original objects involve the creation or the removal of an interaction with the flight plan.
- the modifications on the derived objects are made, and a feedback message is sent to the sending system, with all the changes applied, on the original objects and the derived objects.
- an interaction between the flight plan and other objects involves placing or removing pseudo-points when the flight plan enters or leaves a closed surface.
- the addition or deletion of pseudo-points can occur, either when a closed surface is added or deleted, or when the flight plan is modified.
- Pseudo-points can be associated with flight plan functions depending on the meaning of the closed surface. Figure 6 provides an example of such an association.
- derivative objects can be used, according to different embodiments of the invention.
- the interaction between the flight plan and a surface or a volume can generate the production and modification of objects such as 4D volumes, varying over time.
- these volumes may represent the entry of the aircraft into a danger zone.
- the flight plan 410 initially comprises the points 420, 421 and 422.
- Two closed surfaces 430, 440 are defined in the environment of the flight plan. Initially, the flight plan crosses the surface 440, entering it at pseudo-point 441, and exiting at pseudo-point 442.
- the flight plan is then modified into a flight plan 411, by deleting the waypoint 421: the aircraft then goes directly from point 420 to point 422. It then no longer crosses zone 440, but zone 430: the pseudo-points 441 and 442 are deleted, but the pseudo-points 431 and 432 are added, respectively at the entry and exit of the aircraft from the closed surface 430.
- FIG. 5 represents a second example of creation of derived objects, before and after revision of a flight plan, in a set of embodiments of the invention.
- the flight plan 510 consists of waypoints 520, 521 and 522, and crosses the closed zone 530. Derived objects are thus present: the pseudo-points 540 and 541, respectively representing the entrance and the exit from the closed surface 530.
- the flight plan 510 is modified into a flight plan 511: the waypoint 521 is replaced by the point 523.
- the flight plan then still crosses the surface 530, but the entry and exit points are modified. . Consequently, the pseudo-points 540 and 541 are deleted, and replaced by the pseudo-points 542 and 543 respectively located at the new entry into the area 530, and at the new exit from the area.
- FIG. 6 represents an example of creation of a derived object function of a flight plan after insertion of an original object closed surface, in a set of embodiments of the invention.
- a closed surface 620 is added on the ground side, delimiting an offset navigation zone (lateral shift) of distance 5 nautical miles to the right of the flight plan 600. This surface is crossed by the flight plan. After addition on the ground side, the surface is sent to the on-board system.
- the on-board system checks whether the interaction between the surface and the flight plan induces the creation of derived objects.
- the answer is positive, and two waypoints 630 and 631 are added to the flight plan, respectively at the entry of the flight plan into the surface, and at the exit of the flight plan from the surface.
- These points flight paths are associated respectively with a start and end of flight offset function (lateral shift) of 5 nautical miles.
- This example is given by way of non-limiting example only and, in general, the interaction of a surface with a flight plan to generate the creation of waypoints on the flight plan, associated with a function depending on the meaning of the closed surface.
- FIGS. 7a and 7b respectively represent an example of coding of an object, and an example of coding of a flight plan revision, according to a set of embodiments of the invention.
- the calculation units 1040, 1140 are configured to encode the objects added or modified before sending a message, and to decode, symmetrically, the object. upon receipt of a message for inclusion.
- the coding of additions or modifications can take different forms. For example, a label can be assigned to added and / or modified objects. A time stamp can also be inserted, corresponding to the last modification of the object.
- an object 710a is defined by one or more attributes, which can for example be chosen from the following attributes: type, position, label, text, function.
- the object 710a can for example be a context or environment object.
- the encoding of the object is based on a list of predefined codes defining the different types of objects and attributes, and consists of representing the object as follows:
- a predefined code representing the type of objects then, for each attribute present for the object, a predefined code representing each type of attribute.
- These sets of codes represent a section of code 721a.
- This section can also include an object identifier chosen from identifiers of an object among table 730a of objects already added in the interface. This makes it possible to detect that the coding defines a modification of an object already present, and not the addition of a new object; - then, an alphanumeric sequence of characters 722a defines, for each attribute, the associated value.
- an object could be represented as below:
- each type of object is coded in alphanumeric form.
- an object of type "zone” will be represented by the attribute "Z”
- an object of type "Mountain wave” by the attribute "M”;
- each type of object is associated with a set of predefined attributes.
- attributes of a zone Z will be a series of positions defined in the form of latitude and longitudes;
- a series of alphanumeric characters is inserted for each of the attributes, for example a series of characters representing the successive latitudes and longitudes for an object of zone type.
- the reverse operation can be done: first the code section 721a is decoded, which makes it possible to determine what type of object is decoded, and what attributes are present. Then, the alphanumeric sequence 722a is read in order to provide a value for each of the attributes.
- each type of attribute is associated with a sequence of alphanumeric characters of predefined length.
- the geographic coordinates of objects can be defined by a series of characters of a given length representing their latitude and longitude.
- the encoding of objects according to different embodiments of the invention can be combined with the encoding, standardized, of waypoints.
- the standard code of a waypoint can be inserted into the code of the object exchanged between interfaces according to the invention.
- FIG. 7b An example of coding of flight plan modifications is presented in FIG. 7b.
- this is only a non-limiting example, and any type of coding allowing deterministic coding and decoding of flight plan modifications can be used according to various embodiments of the invention.
- a modification of the flight plan 710b can be defined by one or more waypoints, and one or more flight plan functions.
- the functions can for example be trajectories resulting from specific functions of the onboard system, such as the offset trajectory (lateral offset).
- a 720b coding of the flight plan modifications may include:
- a section of code 721 b comprising: a predefined code defining that it is a modification of the flight plan; o for each of the functions of the modification, a predefined code defining the type of function.
- a function When a function is modified, its identifier can be indicated, from among a table 730b of the functions of the flight plan; - an alphanumeric sequence 722b defining the coordinates of each waypoint, and the parameters of the added functions.
- this convention allows changes to the flight plan to be exchanged transparently between the different systems using a shared interface.
- the alphanumeric sequence only contains the parameter values corresponding to the coding of the waypoints and functions actually present in the modification. This convention therefore allows compact coding of the modifications to the flight plan, and bandwidth savings.
- the receiving system upon receipt of a modification of the set of objects, applies the modification, presents it to an operator, and, if the latter approves the modification, recodes the modification, as applied to the receiving system, to return it to the sending system. It is then sufficient for the sending system to compare the codes of the modification sent and the modification received to check the integrity of the modification on the receiver side: if the codes are identical, the modification will have been applied identically to the receiver side. .
- This code mechanism therefore provides a simple and efficient method of validating the integrity of the changes with all the systems involved, and ensuring that the changes are correctly synchronized by the different systems.
- FIG. 8 represents a method of applying a modification to a ground system, and of validating the modification to an on-board system in a set of embodiments of the invention.
- a modification of a set of objects of an interface is carried out by an air traffic controller in the system 1100, and sent to the system 1000.
- this method is given by way of non-limiting example only: some steps are only used for certain embodiments of the invention.
- systems 1000 and 1100 are given by way of example only. More generally, this method can be implemented between a system having only access to the shared interface, and a system having access to a flight management system. Likewise, the pilot and the air traffic controller can be replaced by other operators, such as a remote drone pilot.
- Figures 8 and 9 show examples of creating ground-side and edge-side objects, respectively. Indeed, although the ground-side and edge-side interaction exhibits a large number of symmetrical characteristics, in a set of embodiments of the invention, certain differences are present. For example, on-board modifications can be considered to have priority over modifications on the ground side. Thus, some modifications on the edge side do not require validation on the ground side. Likewise, the interaction with the avionics takes place on the board side. These principles may also, more generally, be applicable to an interaction between a system having access only to the interface, and a system having access to a flight management system.
- Figures 8 and 9 are presented, for the sake of simplicity, for the interaction between two systems.
- the invention is applicable to interactions between more than two systems on the same shared interface: in this case, it suffices to send the modifications to all of the systems, and to extend the concept of validation to the return of all the systems, a modification being considered as definitively adopted only when it is validated by all the systems.
- the steps of method 8000 can in particular be executed by calculation units 1040, 1140.
- the air traffic controller performs a modification of the set of objects of the interface, as represented by the system 1100.
- This modification may for example consist of the creation of an object, the modification or deletion of an existing object, or a modification of the flight plan.
- the modification is carried out in particular by the inputs 1120, in connection with the display 1110.
- the modification can for example consist of a modification of the flight plan 210, the deletion or the modification of one of the original objects of the interface (for example one of the objects 220, 221, 240, 241, 250, 251), or adding a new object.

- step 8100 the impact of the modification on the derived objects is verified, for example on the model explained with reference to FIGS. 4 and 5: if, following the modification, derived objects must be created, modified or deleted, these modifications are evaluated and displayed in step 8100.
- step 8110 the modification, as applied in system 1000, is recoded.
- This recoding step 8110 therefore comprises the encoding of the received modification, as actually applied at the system 1000 level, and if applicable, an encoding of the modifications of the derived objects.
- changes to the derived objects are calculated, encoded, and sent later.
- step 8120 the recoding of the modification is sent to the system 1100.
- step 8130 the recoding is received by the system 1100.
- step 8140 the system 1100 verifies that the recoding (excluding modifications of the derived objects) is identical to the initial encoding, carried out in step 8020).
- step 8160 The modification is then canceled in step 8160.
- This step 8160 can in particular include a notification from the air traffic controller that the modification is canceled, and the cancellation of the display. It can also include sending a message to system 1000, so that it also cancels the change on its side.
- the air traffic controller can then, if desired, re-make a modification, and method 8000 is executed again, with a new modification.
- step 8180 the system 1000 checks whether the modifications have an impact on the flight plan. This is the case, for example, if the modification sent is a modification of the collaborative flight plan, or if certain objects impact the flight plan, as in the example in Figure 6.
- step 8200 validation of the pilot is received. In the event that the pilot rejects the modifications to the flight plan implied by the modification, this modification is canceled. A message is sent to the system 1100 to inform the air traffic control, and to cancel the modification on the system 1100 side. After validation by the pilot, the modification of the flight plan is sent in step 8210 to the flight management system 1050.
- the flight management system rejects the modification, for example if it is not compatible with the aerodynamic performance of the aircraft, the modification is canceled, in both the 1000 and 1100 system.
- Figure 9 shows a method of applying a modification to an on-board system, and validating the modification to a ground system in a set of embodiments of the invention.
- a modification of a set of objects of an interface is carried out in the system 1000, either by action of the pilot, or by reception of a modification of the flight plan by the flight management system 1050, and sent to the system 1000.
- this method is given by way of non-limiting example only: certain steps are only used for certain embodiments of the invention.
- systems 1000 and 1100 are given by way of example only. More generally, this method can be implemented between a system having only access to the shared interface, and a system having access to a flight management system. Likewise, the pilot and the air traffic controller can be replaced by other operators, such as a remote drone pilot.
- the steps of method 9000 can in particular be executed by calculation units 1040, 1140.
- a modification of the set of objects of the interface is received as input.
- This modification can for example consist in the creation of an object, the modification or the modification. deletion of an existing object, or a modification of the flight plan.
- the modification can in particular be initiated by: the pilot, who enters them through the inputs 1020, in connection with the display 1010;
- the flight management system 1050 which initiates a modification of the flight plan. If this modification is validated by the pilot, the modification is received as input to method 9000.
- the modification can for example consist of a modification of the flight plan 210, the deletion or the modification of one of the original objects of the interface (for example one of the objects 220, 221, 240, 241, 250, 251), or adding a new object.
- step 9020 If, following the modification, derived objects are to be created, modified or deleted, these modifications are evaluated and displayed in step 9020.
- the pilot can then, in a set of embodiments of the invention, accept or reject modifications. If he refuses, the change is canceled.
- the modification does not come from the flight management system 1050, but involves a modification thereof, and where the pilot accepts the modifications, the modification of the flight plan is sent to the flight management system. 1050.
- the flight management system rejects the modification, for example if it is not compatible with the aerodynamic performance of the aircraft, the modification is canceled.
- step 9040 pilot validation is received, for all modifications.
- the modification or modifications (initial modification, modifications of the derived objects, modifications of the flight plan following the FMS dispatch) are coded, for example according to the principles discussed with reference to FIGS. 7a and 7b.
- step 9060 all of the modifications are sent to the system 1100.

- the air traffic controller must validate or not the modifications.
- the air traffic controller may need to validate all changes.
- the modifications sent by the on-board can all be automatically applied to the ground, without validation from the air traffic controller.
- only certain types of modifications for example, modifications to the flight plan) can be submitted for validation by the air traffic controller.
- the modification is subject to validation by the air traffic controller, the latter can validate or reject the modification, in particular via inputs 1120.
- the feedback (validation or rejection of the air traffic controller) is received.
- the subsequent steps 9100, 9110, 9120 are also activated only if the modification is subject to validation by the air traffic controller.
- step 9100 the type of return is tested.
- a rejection message 9110 is sent from system 1100 to system 1000.
- the changes are reverted at step 9120 in system 1000, which therefore reverts to state prior.
- step 9130 the modifications, as applied in the system 1100, are recoded.

- the 9000 method demonstrates the ability of the invention to allow several systems to work, collaboratively, on flight plans, while ensuring that the modifications made by either side are correct. synchronized between the different systems.
- a system can, for example, "centralize" operations.
- the modifications of the objects of the collaborative interface are propagated from the central system to the others, and the examples developed above can be generalized. For example, if a change is made on the central system, it will be propagated to other systems, and can be rolled back if at least one of the other systems rejects the change. If a modification is received by the central system, and validated by the latter, a message comprising the modification can be sent to the other systems. This allows the collaborative interface to be deployed to more than two systems.
