Description

Title of the invention: Method for sharing data between aeronautical equipment, associated electronic data sharing system and computer program

[0001] The present invention relates to a method for sharing data between aeronautical equipment.

[0002] The present invention also relates to an electronic system for sharing data between aeronautical equipment and a computer program configured to implement such a method.

[0003] The invention relates to the field of communication between aeronautical equipment.

[0004] During an aircraft flight mission, a plurality of agents are involved. Indeed, during his flight, a pilot of the aircraft is at least in communication with an air traffic controller with whom he can exchange data on his flight mission. During such communications, as a general rule, each user requests from his counterpart the data he needs to verify that the situation is in accordance with a flight plan or to determine different commands related to the aircraft. Following the request, the counterpart consults avionics equipment providing him with the requested data and transfers them to the first user, by speech or via digital communication between the aeronautical equipment. With this type of communication protocol, the data is said to be pulled. In other words, the data requester is at the origin of the engagement of the communication protocol.Alternatively, it is up to the data requester to indicate their need for data in order for it to be provided, with the data provider only responding to requests from the requester.

[0005] Such a mechanism may prove sufficient when only one aircraft pilot and one air traffic controller are communicating with each other and the situation is not critical. However, as soon as a larger number of agents are involved, the quantity of information requested makes these communications too slow. Similarly, when the situation is critical, for example for managing a breakdown, the speed of information transfer is a key factor that discriminates against conventional communication protocols.

[0006] To overcome this problem, we know the push data mechanism. Indeed, in this mechanism, the information from each piece of equipment is fully transmitted to the other aeronautical equipment without a prior request for data being necessary. Thus, the user of a The respective equipment does not need to indicate its need for the desired data to be transmitted to it. This mechanism therefore reduces the time taken to obtain data for each user.

[0007] However, as soon as the number of users involved exceeds two or as soon as the situation becomes critical, the quantity of data available to each user is too large for the user to have the time to process them, to determine which ones he needs. In addition, too large a quantity of data available increases the cognitive load of the users, or even promotes the feeling of panic among users of the various aeronautical equipment which can lead to late or erroneous decision-making.

[0008] Furthermore, communicating too much data is likely to overload the communications channels between the aeronautical equipment, leading to slowdowns in obtaining the data.

[0009] The invention aims to overcome this problem by limiting the quantity of information available to users.

[0010] To this end, the present invention relates to a method for sharing data between aeronautical equipment, at least one aeronautical equipment being included in an aircraft, the aircraft implementing a flight mission,

[0011] the method being implemented by an electronic data sharing system and comprising the following successive steps for one of said aeronautical equipment:

[0017] The filtering step makes it possible to sort all of the data to obtain only the data relevant to the current mission. In other words, only the data that each user and / or aeronautical equipment must be aware of are determined and transmitted to each aeronautical equipment.

These characteristics and advantages of the invention will appear more clearly in the reading of the description which follows, given solely as a non-limiting example, and made with reference to the attached drawings, in which:

[0040] [Fig.l] [Fig.l] is a schematic view of an aeronautical assembly comprising a data sharing system according to the invention;

[0041] [Fig.2] [Fig.2] is a flowchart of a data sharing method according to the invention;

[0042] [Fig.3] [Fig.3] is a diagram showing data exchanges in the data sharing system of [Fig.l];

[0043] [Fig.4] [Fig.4] is a schematic view of an aeronautical assembly according to a variant embodiment; and

[0044] [Fig.5] [Fig.5] is a diagram representing data exchanges in a data sharing system included in the aeronautical assembly of [Fig.4].

[0045] In [Fig.l] an aeronautical assembly 10 is shown according to a first embodiment. The aeronautical assembly 10 comprises at least one aircraft 15, a ground station 20 and an electronic data sharing system 25.

[0046] The aeronautical assembly 10 implements a mission. The mission is for example the management of an anomaly in an environment of the aircraft 15. To carry out this mission, the aircraft 15 and the ground station 20 are capable of implementing one or more corrective actions.

[0047] For example, the anomaly belongs to a predefined set of anomalies. For each anomaly, a set of corrective action(s) and a set of filtering rule(s) are predefined.

[0048] The aircraft 15 is for example an airplane, a helicopter, or a drone. Preferably, the aircraft 15 is an airplane, for example a commercial airplane.

[0049] The anomaly is typically any type of hazard, i.e. unforeseen event, concerning the aircraft 15 and / or the ground station 20, and justifying communication between the aircraft 15 and the ground station 20.

[0050] According to a first example, the anomaly is an engine failure of the aircraft 15. The ground station 20 is an air traffic control tower.

[0051] According to a second example, the anomaly is a fire in an environment of the aircraft 15. The aircraft 15 is a Canadair®. The ground station 20 is then a ground fire service.

[0052] According to a third example, the anomaly is a sick passenger in critical condition on board aircraft 15.

[0053] According to a fourth example, the anomaly is a request, coming from the ground station 20, that the aircraft 15 leave a group of aircraft alongside which it was flying until now.

[0054] According to a fifth example, the anomaly is a victim of an injury in mountain. Aircraft 15 is a rescue helicopter, and Ground Station 20 is a ground firefighting team.

[0055] The aircraft 15 comprises a plurality of sensors 26 capable of measuring different data linked to the aircraft 15. The aircraft 15 comprises a first aeronautical equipment 30 receiving the data measured by the sensors 26, calculating other data and storing the measured and calculated data POP_A (from the English Personal Operational Picture).

[0056] The ground station 20 is capable of communicating with the aircraft(s) 15 and with the sharing system 25.

[0057] The first aeronautical equipment 30 is for example a flight management system, or FMS (from the English Flight Management System), of the aircraft 15. Among the POP_A data stored in the first equipment 30, some are relevant for a user of the first aeronautical device 30, i.e. a pilot of the aircraft 15. These data form a first PROP_A (from the English Personal Relevant Operational Picturë) data set. “User-relevant data” means data useful or necessary for the user of aeronautical equipment for carrying out the mission. The first PROP_A data set is respective of the first equipment 30.

[0058] Just like the aircraft 15, the ground station 20 also comprises sensors 31 capable of measuring data relating to said ground station 20 or to an environment of the aircraft 15. The ground station 20 further comprises a second aeronautical equipment 35 receiving the data measured by the sensors 31, calculating other data and storing the measured and calculated data POP_B.

[0059] Each aeronautical equipment 30, 35 optionally comprises a display screen capable of displaying data received from the sharing system 25 as will be described later.

[0060] Preferably, each aeronautical equipment 30, 35 is furthermore, or alternatively instead, configured to calculate commands of the aircraft 15 from the data received from the sharing system 25.

[0061] According to the first example, the second aeronautical equipment 35 is an electronic air traffic control device. A user of the second aeronautical equipment 35 is an air traffic controller.

[0062] According to the second example, the second aeronautical equipment 35 is a data concentration system of the fire department. The user of the second equipment 35 is a firefighter.

[0063] Among the data stored in the second aeronautical equipment 35, some are relevant for the user and form a second PROP_B data set.

[0064] The electronic data sharing system 25 comprises a plurality of devices elementary electronic positives 40. In the example shown in [Fig.l], the data sharing system 25 comprises a first 40A, a second 40B and a third 40C elementary devices.

[0065] The sharing system 25 comprises at least one module 45 for obtaining a set of PROP_A, PROP_B data from one of the aeronautical equipments 30, 35, an addition module 50, a filtering module 55, at least one transmission module 60, and preferably at least one enrichment module 63.

[0066] In the example shown in [Fig.l], the sharing system 25 comprises a first obtaining module 45A, a first transmission module 60A, and preferably a first enrichment module 63A included in the first elementary device 40A. The sharing system 25 further comprises a second obtaining module 45B, a second transmission module 60B and preferably a second enrichment module 63B included in the second elementary device 40B. The addition module 50 and the filtering module 55 are, for their part, included in the third elementary device 40C distinct from the first 40A and second 40B elementary devices.

[0067] The first elementary device 40A is connected to the first aeronautical equipment 25 and to the third elementary device 40C. The second elementary device 40B is connected to the second aeronautical equipment 30 and to the third elementary device 40C.

[0068] According to a non-represented embodiment, the first elementary device 40A is included in the aircraft 15, and the second elementary device 40B is included in the ground system 20.

[0069] In the example of [Fig.l], each elementary device 40A, 40B, 40C is a computer comprising respectively a processor 65A, 65B, 65C and a memory 70A, 70B, 70C associated with the processor 65A, 65B, 65C and storing software instructions suitable for being executed by said processor 65A, 65B, 65C.

[0070] In [Fig.l], the modules 45A, 45B, 50, 55, 60A, 60B, 63A, 63B, are each produced in the form of one or more software programs, or a software brick, executable by the respective processor 65A, 65B, 65C.

[0071] Each software is further capable of being recorded on a medium, not shown, readable by computer.

[0072] The computer-readable medium is, for example, a medium capable of storing electronic instructions and of being coupled to a bus of a computer system. For example, the readable medium is an optical disk, a magneto-optical disk, a ROM memory, a RAM memory, any type of non-volatile memory (for example EPROM, EEPROM, FLASH, NVRAM), a magnetic card or an optical card. A computer program is then stored on the or each readable medium. including software instructions.

[0073] In a variant not shown, each module 45A, 45B, 50, 55, 60A, 60B, 63A, 63B, or each elementary device 40A, 40B, 40C, or even the data sharing system 25 in its entirety, is produced in the form of a programmable logic component, such as an FPGA (Field Programmable Gate Array) or even an integrated circuit such as an ASIC (Application Specific Integrated Circuit).

[0074] Each obtaining module 45A, 45B is configured to obtain the PROP_A, PROP_B data set from the aeronautical equipment 30, 35 with which it is associated.

[0075] The first obtaining module 45A is configured to obtain the first data set PROP_A from the first aeronautical equipment 30 and the second obtaining module 45B is configured to obtain the second data set PROP_B from the second aeronautical equipment 35.

[0076] In the first example, the first PROP_A data set includes: a speed of the aircraft 15, an altitude of the aircraft 15, a position of the aircraft 15, a flight time to an initial destination of the aircraft 15, a quantity of fuel in the aircraft 15, a pressure in each engine of the aircraft 15, and a power of each engine of the aircraft 15.

[0077] In the first example, the second data set PROP_B comprises: an indication of traffic in an area around the aircraft 15, a delimitation of a no-fly zone, a radio communication channel with a pilot of the aircraft 15, and meteorological information in an environment of the aircraft 15.

[0078] In the second example, the first data set PROP_A comprises: a speed of the aircraft 15, an altitude of the aircraft 15, a position of the aircraft 15, a quantity of fuel in the aircraft 15, the state of water dumping stored in a tank of the aircraft 15, and a quantity of water in the tank of the aircraft 15.

[0079] In the second example, the second PROP_B dataset includes: a position of the fire, a wind direction at the fire location, at least one terrain feature at the fire location, and a position of the firefighters on the ground.

[0080] The addition module 50 is configured to add the data set PROP_A, PROP_B from one of the obtaining modules 45A, 45B, to a common group COP (Common Operational Picture) of data common to all the aeronautical equipment 30, 35.

[0081] Preferably, the addition module 50 is configured to add each data set PROP_A, PROP_B to the common group COP.

[0082] For example, the addition module 50 is configured to perform a concatenation of the PROP_A, PROP_B data sets to the data already contained in the common group COP.

[0083] In the first example, the common group COP comprises the following data: the speed of the aircraft 15, the altitude of the aircraft 15, the position of the aircraft 15, the flight time to an initial destination of the aircraft 15, the quantity of fuel in the aircraft 15, the pressure in each engine of the aircraft 15, the power of each engine of the aircraft 15, the ventilation state of a cabin of the aircraft 15, an element relating to passengers of the aircraft 15, the indication of traffic in an area around the aircraft 15, the delimitation of a no-fly zone, the radio communication channel with a pilot of the aircraft 15, the meteorological information in an environment of the aircraft 15, and information on other priority aircraft in an environment of the ground station 20.

[0084] In the second example, the common group COP comprises the following data: the speed of the aircraft 15, the altitude of the aircraft 15, the position of the aircraft 15, the quantity of fuel in the aircraft 15, the release status of the water stored in the tank of the aircraft 15, the quantity of water in the tank of the aircraft 15, the position of the fire, the direction of the wind at the location of the fire, at least one terrain characteristic at the location of the fire, and the position of the firefighters on the ground.

[0085] Preferably, the addition module 50 is configured to, if the data of at least one data set PROP_A, PROP_B includes data concerning elements already present in the common group COP, update said data included in the group as COP from those present in the data set PROP_A, PROP_B.

[0086] In other words, in the first example, the addition module 50 is configured to, if the common group COP already includes a position of the aircraft 15, update the position of the aircraft 15 from the position present in the first data set PROP_A.

[0087] The filtering module 55 is configured to filter the data of the common group COP via filtering rules specific to the mission, to determine at least one common relevant data CROP (Common Relevant Operational Picture), also called shared relevant data or first relevant data.

[0088] The at least one common relevant data CROP is relevant for all the aeronautical equipment 30, 35 of the avionics assembly 10 and / or for all the users of said equipment 30, 35, in order to carry out the mission.

[0089] In particular, each filtering rule is preferentially defined by users planning the missions and corrective actions to be implemented to accomplish these missions. Thus, each filtering rule is for example associated with a corrective action.

[0090] In the first example, a corrective action is the planning of a flight plan following the engine failure, a predefined filtering rule being intended to determine the data needed for flight plan planning.

[0091] In the second example, a predefined corrective action is the determination of a release axis for the water stored in the Canadair® tank to fight the fire, a predefined filtering rule being intended to determine the data necessary for the determination of said release axis.

[0092] The filtering module 55 is more precisely configured to calculate, for each data item of the common group COP, a relevance indicator from the predefined filtering rules specific to the mission.

[0093] These filtering rules are suitable for associating with each data item, a predefined indicator according to the importance, also called relevance, of the data item for all users of aeronautical equipment 30, 35, in order to implement the associated corrective action. The predefined indicator is for example a numerical value, such as a number between 0 and 100, where the minimum value 0 corresponds to data that is not very relevant for all users, and the maximum value 100 corresponds to data that is extremely relevant for all users.

[0094] By way of example, in the first example, the predefined indicator associated with a quantity of fuel in the aircraft 15 takes the value 100, while the indicator associated with the indication of autopilot engaged takes the value 0. This makes it possible to realize that the quantity of fuel in the aircraft 15 is much more important for all users than the indication of autopilot engaged, for the planning of the flight plan following the engine failure.

[0095] Preferably, in the first example, the predefined indicator associated with the speed of the aircraft 15 takes the value 81.

[0096] Furthermore, the filtering module 55 is configured to compare the relevance indicator to a predefined threshold. A threshold value is chosen according to the quantity of data that it is desired to transmit to the aeronautical equipment, as described below. The filtering module 55 is configured to determine the common relevant data CROP, as being the data of the common group COP, for which the relevance indicator is greater than or equal to the threshold. In the first example detailed above, the threshold value is for example set to 50.

[0097] In the first example, the common relevant data CROP includes: the speed of the aircraft 15, the altitude of the aircraft 15, the position of the aircraft 15, the flight time to an initial destination of the aircraft 15, the quantity of fuel in the aircraft 15, the pressure in each engine of the aircraft 15, the power of each engine of the aircraft 15, the indication of traffic in an area around the aircraft 15, and the delineation of a no-fly zone.

[0098] In the second example, the common CROP relevant data includes: the position of the fire, the wind direction at the fire site, at least one terrain feature at the fire site, and the position of firefighters on the ground.

[0099] The first transmission module 60A is configured to transmit to the first aeronautical equipment 30, only the relevant common data CROP. The second transmission module 60B is configured to transmit to the second aeronautical equipment 35, only the relevant common data CROP.

[0100] Advantageously, each transmission module 60A, 60B is configured to transmit to each aeronautical equipment 30, 35, only the relevant common CROP data which do not come from said aeronautical equipment 30, 35.

[0101] Each enrichment module 63A, 63B is configured to add to the PROP_A, PROP_B data set of the corresponding aeronautical equipment 30, 35, the relevant common data CROP.

[0102] As an optional addition, the first enrichment module 63A is configured to add to the first PROP_A data set of the first aeronautical equipment 30, only the relevant common CROP data which are not already present in the first aeronautical equipment 30, i.e. the relevant common CROP data from the second PROP_B data set of the second aeronautical equipment 35. The first enrichment module 63A is configured to, if the first PROP_A data set comprises data relating to the second equipment 35 from a previous enrichment, update said data from the new data of the relevant common CROP data, from the second PROP_B data set.

[0103] According to this optional addition, the second enrichment module 63B is configured in a manner analogous to the first enrichment module 63A by replacing the first equipment 30 with the second equipment 35 and the first data set PROP_A with the second data set PROP_B.

[0104] As an optional addition, each obtaining module 45A, 45B is configured to obtain the data set PROP_A, PROP_B in the following manner, explained for the first obtaining module 45A.

[0105] The first obtaining module 45A is configured to receive the POP_A data stored in the first aeronautical equipment 30, i.e. the POP_A data from the sensor(s) 26 associated with said aeronautical equipment 30 and / or determined by the first aeronautical equipment 30.

[0106] The first obtaining module 45A is further configured to select, from the received data POP_A, individual relevant data, also called local relevant data or second relevant data.

[0107] These individual relevant data are respective of the first aeronautical equipment 30. The individual relevant data are relevant for the user of the first aeronautical equipment 30, in order to control said first aeronautical equipment 30 within the framework of the mission.

[0108] Preferably, the first obtaining module 45A is configured to apply a methodology called MERIA in which the operators of the aircraft 15 and the ground station 20 have each predefined, for each mission, the information considered necessary for them. For example, this information forms a predefined column vector. Thus, the first obtaining module 45A is configured to select, from the received data POP_A, the individual relevant data as being the received data corresponding to those indicated in the predefined column vector.

[0109] The first obtaining module 45A is further configured to form the first data set PROP_A by concatenating the selected individual relevant data.

[0110] According to this optional addition, the second obtaining module 45B is configured in a similar manner to the first obtaining module 45A, except that it is configured to receive the POP_B data from the second aeronautical equipment 35, to select from among these POP_B data, those which are relevant for the user of the second aeronautical equipment 35, and to form the second PROP_B data set.

[0111] The operation of the electronic sharing system 25 will now be described with reference to [Fig.2] representing a flowchart of a data sharing method 100, and to [Fig.3] representing the data flows during the method 100.

[0112] First, the operation of the sharing system 25 is described based on the first example.

[0113] Initially, the aircraft 15 flies and is able to communicate with the ground station 20 and the sharing system 25.

[0114] At a given time instant, the anomaly appears. The anomaly is for example an engine failure of the aircraft 15. In this example, the first aeronautical equipment 30 is a flight computer of the aircraft 15. In this example also, the ground station 20 is an air traffic control tower, the second aeronautical equipment 35 being included in said air traffic control tower 20.

[0115] During an obtaining step 110, the first obtaining module 45A obtains the first PROP_A data set from the first aeronautical equipment 25

[0116] Preferably, the obtaining step 110 comprises a receiving sub-step 112 during which the first obtaining module 45A receives the POP_A data stored in the first aeronautical equipment 30, from said first equipment 30.

[0117] The obtaining step 110 further comprises a selection sub-step 114 during which the first obtaining module 45A selects, from the received data POP_A, the individual relevant data associated with the first aeronautical equipment 30, as described previously.

[0118] Preferably, during the selection sub-step 114, the obtaining module 45A selects the individual relevant data associated with the first aeronautical equipment 30 as being the data corresponding to the predefined column vector established by the operator of the first aeronautical equipment 30 prior to the mission.

[0119] The obtaining step 110 finally comprises a sub-step 116 of forming the first data set PROP_A, from the individual relevant data. For example, the first obtaining module 45A is configured to concatenate the individual relevant data associated with the first equipment 30, to form the first data set PROP_A.

[0120] In [Fig.3], the POP_A data received from the first aeronautical equipment 30 are represented on the left and step 110 is represented by the arrow joining said POP_A data to the first PROP_A data set.

[0121] In the first example, the POP_A data received from the first aeronautical equipment 30 comprises: the speed of the aircraft 15, the altitude of the aircraft 15, the position of the aircraft 15, the flight time to an initial destination of the aircraft 15, the indication of autopilot engaged, the quantity of fuel in the aircraft 15, the pressure in each engine of the aircraft 15, the power of each engine of the aircraft, the angle of attack of the aircraft 15, a position of the landing gear of the aircraft 15, a position of the flaps on wings of the aircraft 15, a state of an electric generator of the aircraft 15, an oil pressure in the engine(s) of the aircraft 15, a ground temperature at the initial destination location of the aircraft 15, the ventilation state of a cabin of the aircraft 15, and the passenger element of aircraft 15.

[0122] In the first example, the first PROP_A data set includes: the speed of the aircraft 15, the altitude of the aircraft 15, the position of the aircraft 15, the flight time to an initial destination of the aircraft 15, the quantity of fuel in the aircraft 15, the pressure in each engine of the aircraft 15, the power of each engine of the aircraft, the ventilation state of a cabin of the aircraft 15, and the element relating to the passengers of the aircraft 15.

[0123] The method 100 further comprises an addition step 120 during which the addition module 50 adds the first data set PROP_A to the common group COP as described previously.

[0124] Preferably, during the addition step 120, if the data of the first data set PROP_A includes data concerning elements already present in the common group COP, the addition module 50 updates said data from those present in the first data set PROP_A. By "updating a piece of data from the common group COP" is meant the deletion of the previous piece of data already contained in the common group COP, and its replacement by the corresponding piece of data from the data set PROP_A.

[0125] In [Fig.3], the addition step 120 is represented by the arrow connecting the first set from PROP_A data to the common group COP.

[0126] The method further comprises a filtering step 130 during which the filtering module 55 filters the data of the common group COP to determine the relevant common data CROP.

[0127] For this purpose, the filtering step 130 comprises a calculation sub-step 132 during which the filtering module 55 calculates a relevance indicator for each data item of the common group COP. For this, the filtering module 55 uses the predefined filtering rules as described previously.

[0128] Then, the filtering step 130 comprises a sub-step 134 of comparing the relevance indicator calculated for each data item of the common group COP, to the predefined threshold.

[0129] Finally, the filtering step 130 comprises a determination sub-step 136 during which the filtering module 55 determines the common relevant data CROP as being the data whose relevance indicator is greater than the predefined threshold.

[0130] In [Fig.3], the filtering step 130 is represented by the downward arrow connecting the common COP group to the relevant common CROP data(s).

[0131] The method further comprises a transmission step 140 during which the second transmission module 60B transmits to the second aeronautical equipment 35, only the common relevant data CROP.

[0132] Preferably, the method 100 comprises, prior to the filtering step 130, the iteration of the obtaining steps 110 and adding steps 120 for each aeronautical equipment 30, 35. Thus, in the present case, the obtaining steps 110 and adding steps 120 are further repeated for the second aeronautical equipment 35. These steps 110, 120 are similar except for the following. During the repeated obtaining step 110, the second obtaining module 45B obtains the second PROP_B data set of the second aeronautical equipment 35, for example by receiving the POP_B data of the second equipment 35, by selecting the individual relevant data associated with the second equipment 35 and by forming the second PROP_B data set by concatenation of said individual relevant data. from the addition step 120, the addition module 50 adds to the common group COP the second data set PROP_B.

[0133] This iteration is represented on the right part of [Fig.3]. In particular, the POP_B data from the second aeronautical equipment 35 are represented on the right and the iteration of the obtaining step 110 is represented by the arrow going from right to left and connecting said POP_B data to the second PROP_B data set.

[0134] In the first example, the POP_B data from the second aeronautical equipment 35 comprises: the indication of traffic in an area around the aircraft 15, the delimitation of a no-fly zone, the radio communication channel with a pilot of the aircraft 15, the meteorological information in an environment of the aircraft 15, and a position of other aircraft at the edge of an airspace, and weather in an environment of the ground station 20.

[0135] In the first example, the second data set PROP_B comprises: the indication of traffic in an area around the aircraft 15, the delimitation of a no-fly zone, the radio communication channel with a pilot of the aircraft 15, and the meteorological information in an environment of the aircraft 15.

[0136] The iteration of the addition step 120 is represented by the arrow going from right to left and connecting the second data set PROP_B to the common group COP.

[0137] Preferably, the obtaining step 110 and the repeated obtaining step 110 are implemented simultaneously by the first 45A and second 45B obtaining modules. Similarly, the adding step 120 and the repeated adding step 120 are implemented simultaneously by the adding module 50.

[0138] Thus, in the first example, the common group COP comprises: the speed of the aircraft 15, the altitude of the aircraft 15, the position of the aircraft 15, the flight time to an initial destination of the aircraft 15, the quantity of fuel in the aircraft 15, the pressure in each engine of the aircraft 15, the power of each engine of the aircraft 15, the ventilation status of a cabin of the aircraft 15, the element relating to the passengers of the aircraft 15, the indication of the traffic in an area around the aircraft 15, the delimitation of a no-fly zone, the radio communication channel with a pilot of the aircraft 15, and the meteorological information in an environment of the aircraft 15.

[0139] It is then understood that in the first example, the common relevant data CROP include: the speed of the aircraft 15, the altitude of the aircraft 15, the position of the aircraft 15, the flight time to an initial destination of the aircraft 15, the quantity of fuel in the aircraft 15, the pressure in each engine of the aircraft 15, the power of each engine of the aircraft 15, the indication of the traffic in an area around aircraft 15, and the delimitation of a no-fly zone.

[0140] Thus, during the transmission step 140, the first transmission module 60A transmits to the first aeronautical equipment 30, only the common relevant data CROP.

[0141] Preferably, the first transmission module 60A transmits to the first equipment 30, only the relevant common CROP data which are not already stored in the first aeronautical equipment 30, i.e. the relevant common CROP data coming from the second aeronautical equipment 35.

[0142] Similarly, the second transmission module 60B transmits to the second equipment 35 only the relevant common CROP data which are not already stored in the second aeronautical equipment 35, i.e. the relevant common CROP data coming from the first aeronautical equipment 30.

[0143] As an optional addition, the method 100 comprises an enrichment step 150 during which the enrichment modules 63A, 63B enrich the PROP_A, PROP_B data sets by adding the relevant common CROP data.

[0144] Preferably, the first enrichment module 63A adds to the first data set PROP_A, the common relevant data CROP which do not come from the first aeronautical equipment 30, i.e. which come from the second aeronautical equipment 35. Similarly, the second enrichment module 63B adds to the second data set PROP_B, the common relevant data CROP which do not come from the second aeronautical equipment 35, i.e. which come from the first aeronautical equipment 30.

[0145] In [Fig.3], the enrichment step 150 is represented by the two arrows 150 connecting the common relevant data CROP to the PROP_A, PROP_B data sets.

[0146] Then, each aeronautical equipment 30, 35 displays the relevant common CROP data intended for the user of said aeronautical equipment 30, 35.

[0147] According to a first operating variant, each aeronautical equipment 30, 35 uses the common relevant data to calculate a command of the aircraft 15, such as a flight command of the aircraft 15.

[0148] According to a second operating variant, one of the aeronautical equipments 30, 35 displays the common relevant data CROP, while the other aeronautical equipment 30, 35 uses the common relevant data CROP to calculate a command of the aircraft 15, such as a flight command of the aircraft 15.

[0149] According to a third variant, the sharing system 25 is concentrated in a single electronic device 40 capable of communicating with each aeronautical equipment 30, 35. The sharing system 25 then comprises a single obtaining module 45 configured so as to combine the configurations of the first 45A and second 45B obtaining modules. Similarly, the sharing system 25 comprises a single transmission module 60 and optionally a single enrichment module 63, each configured to respectively combine the configurations of the first 60A and second 60B transmission modules and the first 63A and second 63B enrichment modules.

[0150] The method 100 applies analogously to the second example with the differences below.

[0151] In the second example, the aircraft 15 is a Canadair® and the ground station 20 is a data concentration system of the fire service. The anomaly is a fire breaking out in the environment of the aircraft 15. The mission is the management of this fire, and one of the corrective actions is the determination of an axis for releasing the water contained in the Canadair®.

[0152] In this second example, the POP_A data received from the first aeronautical equipment 15 includes: the speed of the aircraft 15, the altitude of the aircraft 15, the position of the aircraft 15, the flight time until the fire, the indication of autopilot engaged, the quantity of fuel in the aircraft 15, the pressure in each engine of the aircraft 15, the power of each engine of the aircraft, the angle of attack of the aircraft 15, the state of water dumping stored in the tank of the aircraft 15, and the quantity of water in the tank of the aircraft 15.

[0153] The POP_B data received from the second aeronautical equipment 20 includes: the position of the fire, the wind direction at the fire location, at least one terrain characteristic at the fire location, the position of the firefighters on the ground, a number of ground agents mobilized, a number of vehicles mobilized, a slope of the ground at the fire location, a total surface area of the terrain likely to be affected by the fire, and a quantity of water available in tanks in the vicinity of the fire.

[0154] The first data set PROP_A then comprises: the speed of the aircraft 15, the altitude of the aircraft 15, the position of the aircraft 15, the quantity of fuel in the aircraft 15, the state of release of water stored in the tank of the aircraft 15, and the quantity of water in the tank of the aircraft 15.

[0155] The second PROP_B data set includes: the position of the fire, the wind direction at the fire location, at least one terrain characteristic at the fire location, and the position of the firefighters on the ground.

[0156] The common group COP includes: the speed of the aircraft 15, the altitude of the aircraft 15, the position of the aircraft 15, the amount of fuel in the aircraft 15, the state of water dumping stored in the tank of the aircraft 15, the amount of water stored in the tank of the aircraft 15, the position of the fire, the direction of the wind at the location of the fire, at least one terrain characteristic at the location of the fire, and the position of firefighters on the ground.

[0157] The common relevant data CROP includes: the position of the aircraft 15, the state of release of water stored in the tank of the aircraft 15, the position of the fire, the direction of the wind at the location of the fire, at least one terrain characteristic at the location of the fire, and the position of the firefighters on the ground.

[0158] As an optional addition, the aeronautical assembly 10 comprises several aircraft 15 and / or several ground stations 20.

[0159] Each aircraft 15 comprises a respective first aeronautical equipment 30. The sharing system 25 preferably comprises a first elementary device 40A for each aircraft 15.

[0160] In each first elementary device 40A is then included a first obtaining module 45A, a first transmission module 60A, and preferably a first respective enrichment module 63A.

[0161] Each first obtaining module 45A, transmission module 60A and enrichment module 63A is configured like the first obtaining modules 45A, transmission module 60A and enrichment module 63A described previously.

[0162] Similarly, each ground station 20 comprises a second respective aeronautical equipment 35. The sharing system 25 preferably comprises a second elementary device 40B for each ground station 20. In each second elementary device 40B, there is included a second obtaining module 45B, a second transmission module 60B, and preferably a second enrichment module 63B.

[0163] Each second obtaining module 45B, transmission module 60B and enrichment module 63B is configured like the second obtaining module 45B, transmission module 60B and enrichment module 63B described previously.

[0164] Thus, in this second embodiment, the common group COP comprises the data sets PROP_A, PROP_B of each of the first 30, and second 35 aeronautical equipment.

[0165] Preferably, the number of aircraft 15 is greater than or equal to three.

[0166] During the data sharing method 100, the steps of obtaining 110 and adding 120 are iterated for each aeronautical equipment 30, 35.

[0167] According to a variant shown in Figures 4 and 5, the aeronautical system 10 comprises an aircraft 15, a first ground station 20, a second ground station 20D and a third ground station 20E.

[0168] The first ground station 20 is analogous to the ground station 20 described previously.

[0169] In the first example where the first ground station 20 is an air traffic control tower, the second ground station 20D is an office of a manager of airline fleet and the third ground station 20E is a security service of the destination airport of aircraft 15 which should receive aircraft 15 and secure it.

[0170] In the second example, the first ground station 20 is a fire service, the second ground station 20D is a service for coordinating ground fire teams, and the third ground station 20E is a service for monitoring the terrain by drones, such as rotary-wing drones.

[0171] As shown in [Fig.4], each of the first 20, second 20D and third 20E ground stations comprises respective sensors 31, 31D, 31E and a second aeronautical equipment 35, 35D, 35E similar to those described previously.

[0172] The sharing system 25 comprises a second elementary device 40B, 40D, 40E respective of each ground station 20, 20D, 20E.

[0173] The elementary equipment device 40D, 40E associated with each of the second ground station 20D and the third ground station 20E is similar to the second elementary device 40 associated with the first ground station 20 described previously.

[0174] The second elementary device 40D, 40E associated with each of the second 20D and third 20E ground stations comprises for example a processor 65D, 65E, and a memory 70D, 70E storing an obtaining module 45D, 45E, a second transmission module 60D, 60E, and preferably an enrichment module 63D, 63E.

[0175] According to this variant, the obtaining modules 45A, 45B, 45D, 45E are analogous, i.e. configured to receive the data POP_A, POP_B, POP_C, POP_E from the associated aeronautical equipment 30, 35, 35D, 35E, to select the individual relevant data from these data POP_A, POP_B, POP_C, POP_E, and to form the associated data sets PROP_A, PROP_B, PROP_C, PROP_E, from the selected individual relevant data.

[0176] According to this variant, the mission is implemented by only a subset of the aeronautical assembly 10. The subset comprises at least two elements among the aircraft 15 and the ground stations 20, 20D and 20E.

[0177] For example, the mission is implemented:

[0178] - only by aircraft 15 and first ground station 20,

[0179] - only by aircraft 15 and second ground station 20D,

[0180] - only by aircraft 15 and third ground station 20E,

[0181] - only by the first ground station 20 and the second ground station 20D,

[0182] - only by the first ground station 20 and the third ground station 20E,

[0183] - only by the second ground station 20D and the third ground station 20E,

[0184] - only by aircraft 15, first ground station 20 and second ground station floor 20D,

[0185] - only by aircraft 15, first ground station 20 and third ground station floor 20E,

[0186] - only by aircraft 15, second ground station 20D and third ground station ground station 20E, or by the first ground station 20, the second ground station 20D and the third ground station 20E.

[0187] In particular, the aeronautical assembly 10 is for example capable of implementing several missions, each being implemented by one of the sub-assemblies described above.

[0188] In each of the two examples previously described, the aforementioned mission is implemented by the aircraft 15 and the first station 20.

[0189] According to this variant, the addition module 50 is analogous to the addition module 50 described previously. Thus, the common group COP comprises the concatenation of the data sets PROP_A, PROP_B, PROP_D and PROP_E from each of the elementary devices 40A, 40B, 40D, 40E.

[0190] According to this variant, the filtering module 55 is configured to filter the common group COP to determine the at least one common relevant data CROP for each mission.

[0191] Thus, the at least one common relevant data CROP is respective of the subset implementing the mission.

[0192] In each of the examples detailed above, the at least one common relevant data CROP is therefore respective of the aircraft 15 and of the first ground station 20, the at least one common relevant data therefore bearing the reference CROP_AB.

[0193] According to this variant, at least one relevant data CROP_AB, CROP_AD, CROP_AE, CROP_BD, CROP_BE, CROP_DE, CROP_ABD, CROP_ABE, CROP_ADE, CROP_BDE is capable of being obtained for each of the subsets implementing a respective mission.

[0194] According to this variant, the transmission modules 60A, 60B, 60D, 60E of the elementary devices 40A, 40B, 40D, 40E are configured to transmit, to the corresponding aeronautical equipment 30, 35, 35D, 35E, only the at least one common relevant data item CROP_AB associated with a subset comprising said elementary device 40A, 40B, 40D, 40E.

[0195] In other words, if the mission is only implemented by the aircraft 15 and the first ground station 20, the transmission modules 60D, 60E are not configured to transmit the at least one corresponding relevant data CROP_AB, to the aeronautical equipment 35D, 35E associated with the second 20D and third 20E ground stations.

[0196] According to this variant, the enrichment modules 63A, 63B, 63D, 63E of each elementary device 40A, 40B, 40D, 40E are configured to enrich the set of corresponding PROP_A, PROP_B, PROP_D, PROP_E data, only from the relevant common data CROP_AB associated with a subset comprising said elementary device 40A, 40B, 40D, 40E.

[0197] In other words, if the mission is only implemented by the aircraft 15 and the first ground station 20, the enrichment modules 63D, 63E are not configured to enrich the PROP_D, PROP_E data sets associated with the second 20D and third 20E ground stations from the at least one common relevant data CROP_AB.

[0198] The method 100 for sharing data according to this variant is analogous to that previously described, with the following differences.

[0199] During the obtaining step 110, the PROP_A, PROP_B, PROP_D, PROP_E data set associated with each elementary device is obtained. This is notably visible in [Fig.5] by the arrows 110.

[0200] In the addition step 120, all the data sets PROP_A, PROP_B, PROP_D, PROP_E are added to the common group COP. This is represented in [Fig.5] by the arrows 120.

[0201] During the filtering step 130, the at least one common relevant data CROP_AB is respective of the subset implementing the mission, i.e. the aircraft 15 and the first ground station 20 in the examples described previously.

[0202] The transmission 140 and enrichment 150 steps are implemented only for the subset implementing the mission, i.e. for the aircraft 15 and the first ground station 20 in the examples previously described. In [Fig.5], this is represented by an absence of arrow 140, 150 connecting the at least one common relevant data CROP_AB and the second aeronautical equipment 35D, 35E associated with the second ground station 20D and the third ground station 25E.

[0203] According to this variant, the elements of the aeronautical assembly 10 not implementing the mission are not overloaded with information which does not concern them.

[0204] The present invention then makes it possible to improve the level of knowledge of the aeronautical equipment 30, 35; 30, 35, 35D, 35E and / or associated users, by the pushed data mechanism, without overloading each aeronautical equipment 30, 35; 30, 35, 35D, 35E and / or user.

[0205] In fact, only the data considered relevant for each user and / or aeronautical equipment are transmitted, thus limiting the data load to be processed.

[0206] In addition, this automatic push data mechanism makes it possible to anticipate the needs of aeronautical equipment and / or users, thus saving time for these aeronautical equipment and / or users in implementing corrective actions. This is particularly advantageous in the context of situations critical situations where reaction time is often a limiting factor.

[0207] In addition, the optional enrichment step allows each aeronautical equipment 30, 35; 30, 35, 35D, 35E involved in the mission to take advantage of the data from other equipment 30, 35; 30, 35, 35D, 35E, for example to infer new data which require a complete vision of the aeronautical assembly 10.

[0208] Furthermore, the distribution of the sharing system 25 and the fact that it is not centralized in a single device makes it more robust to potential external attacks.

[0209] In addition, the optional sub-steps during the step 110 of obtaining the PROP_A, PROP_B data set; PROP_A, PROP_B, PROP_D, PROP_E, make it possible to carry out a first limitation of the quantity of data by not taking into account any data which is not relevant for the aeronautical equipment and / or its user. Thus, the quantity of data in the common group COP is limited and the processing of this data is accelerated.
