    [0001] FIELD OF THE INVENTION The invention relates to the field of avionics, and in particular that of mission preparation on the ground, on board and during flight. State of the art The pilot of an aircraft uses the flight plan information in several contexts: within the avionics equipment for the FMS (Flight Management System) function, generally on an "EFB" (Electronic Flight Bag) for example of tablet type, with an "Operational Flight Plan" function or an "Electronic Flight Folder" or by means of a "Card" function (Chari) of the EFB. Flight plan information is also contained in the Flight Planning System (FPS), a part of which is transmitted to air traffic control. The large number of data sources and the diversity of uses of different flight plan information generally involve many manual and cognitive operations by flight personnel (for example, the mission preparer and the pilot of the aircraft). The associated tasks require numerous checks and validations, in coherence. In current avionics systems, the flight plan is generally prepared on the ground by the mission preparer, for example using a tool called the "Flight Planning System". Part of the flight plan is transmitted to the air traffic control for validation. Another part of said flight plan 3023911 is transmitted to the ground via a server on board the aircraft by means of a function called "Operational Flight Plan" or "Electronic Flight Folder". The flight plan information is entered manually, ie one by one and therefore fastidiously in the "Maps" function. The flight plan as such is also entered manually by the pilot in the so-called flight management function in accordance with the instructions issued by the mission preparer. These existing techniques and practices have many disadvantages. First of all, there is no unified input method since up to three different methods are possible to do this. In itself, the learning times are not rationalized and this heterogeneity can be a source of errors or at the very least of slowness. Then there is no integrated check of the entries (eg data consistency). These aspects lead to a cognitive overload of the pilot, which is detrimental to his fatigue since these tedious tasks are generally required just before the flight. There is a need for methods and systems for optimizing flight plan data capture. SUMMARY OF THE INVENTION There is disclosed a computer implemented method of managing data of an aircraft flight plan comprising the steps of collecting initial data from an operational flight plan from a flight plan system. FPS flight planning by an EFB electronic flight bag type electronic device; converting said initial data and communicating said converted data to the avionics system of the flight management system FMS, said FMS being able to calculate an avionic flight plan from the converted data; and retrieve or receive data from the avionic flight plan as processed by the FMS flight management system. In a development, the flight management system FMS verifies the security and / or integrity of the converted initial data by means of 5 predefined compliance rules. In one development, the method further comprises an avionics protocol emulation step by the FMS flight management system to calculate an avionics flight plan from the converted flight plan data. In one development, the method further comprises a step of comparing the avionic flight plan as calculated by the FMS flight management system with the initial operational flight plan data. In one development, the EFB electronic flight bag type electronic apparatus comprises display means and the method comparison step comprising simulating and displaying on said EFB electronic flight bag electronic device the processing avionics initial data from the operational flight plan. In one development, the method further comprises receiving one or more modifications of one or more initial data of the operational flight plan. In one development, the method comprises repeating one or more of said collection, conversion, retrieval, communication, comparison or simulation steps. In one development, the method further comprises a step of encrypting the data before sending to the FMS flight management system. In a development, the electronic flight bag EFB is a tablet computer.
    [0002] There is disclosed a computer program product comprising code instructions for performing one or more steps of the method, when said program is executed on a computer. There is disclosed a system comprising means for carrying out one or more process steps. Advantageously, a dialogue between avionic systems and non-avionic systems is permitted, at least in part, by the invention. Advantageously and in particular, the flexibility and / or the calculation capacity (clean or offset via the cloud) of an EFB-type apparatus can be used for the processing of the data of the flight plan. 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 not limited to, with reference to the figures below: FIG. overall technique of the invention; Figure 2 schematically illustrates the structure and functions of a known FMS flight management system; Figure 3 shows an overview and examples of steps of the method according to the invention; Figure 4 details some examples of steps of the method according to the invention.
    [0003] DETAILED DESCRIPTION OF THE INVENTION Certain terms and technical environments are defined below. The acronym or acronym EFB corresponds to the English terminology "Electronic Flight Bag" and refers to embedded electronic libraries. Generally translated as "electronic flight bag" or "electronic flight bag" or "electronic flight tablet", an EFB is a portable electronic device and used by the flight crew (eg drivers, maintenance, cabin ..). An EFB can provide flight information to the crew, helping them to perform tasks (with fewer papers). In practice, it is usually a commercial computer tablet. One or more applications allow the management of information for flight management tasks. These general-purpose computer platforms are designed to reduce or replace paper-based reference material, often found in the "Pilot Flight Bag" hand baggage, which can be difficult to manipulate. Reference paper documentation usually includes flight manuals, navigation charts, and ground operations manuals. These documentations are advantageously dematerialized in an EFB. In addition, an EFB can host software applications specifically designed to automate manually conducted operations in normal times, such as take-off performance calculations (speed limit calculation, etc.). Different classes of EFB material exist. Class 1 EFBs are portable electronic devices (PEDs), which are not normally used during take-off and landing operations. This device class does not require a specific certification or authorization administrative process. Class 2 EFB devices are normally located in the cockpit, e.g. mounted in a position where they are used during all phases of flight. This class of devices requires prior authorization. Class 1 and Class 2 devices are considered portable electronic devices. Class 3 fixed installations, such as computer carriers or stationary docking stations installed in aircraft cockpit generally require approval and certification by the regulator. The acronym or acronym FMS corresponds to the English terminology "Flight Management System" and refers to the flight management systems of the 10 aircraft. 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 FMS aircraft. An FMS comprises input means and display means, as well as calculation means. An operator, for example the pilot or the co-pilot, can enter via the input means information such as RTAs, or "waypoints", associated with waypoints, ie points vertically. which the aircraft must pass. The calculation means make it possible in particular to calculate, from the flight plan comprising the list of waypoints, the trajectory of the aircraft, as a function of the geometry between the waypoints and / or altitude and speed conditions. The acronym HMI stands for Human Machine Interface (HMI). The entry of the information, and the display of the information entered or calculated by the display means, constitute such a man-machine interface. With known FMS type 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 An EFB 122 may be on board, in a portable manner or integrated into the cockpit EFB may interact (two-way communication 123) with the avionics equipment 121. The EFB may also be in communication 124 with 20 external computing resources, accessible by the network (for example cloud computing or "cloud computing" 125. In particular, the calculations can be made locally on the EFB or in a manner e partial or total 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). This architecture makes it possible to inject flexibility on the side of the EFB 122 while ensuring a controlled security on the on-board avionic side 121. FIG. 2 schematically illustrates the structure and functions of a control system. known FMS flight management. An FMS system 3023911 200 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 5, and at least the following functions: - Navigation (LOCNAV) 201, to perform the optimal location of the aircraft according to the geolocation means 230 such as satellite 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 designated "airways" according to English terminology. The functions which are the subject of the present invention affect or concern this part of the computer. Navigational database (NAVDB) 203, for constructing geographic routes and procedures from data included in the bases relating to points, tags, interception or altitude bequests, etc .; - Performance database, (PERFDB) 204, containing the aerodynamic and engine parameters of the aircraft; Lateral Trajectory (TRAJ) 205, for constructing a continuous trajectory from the points of the flight plan, respecting the performance of the aircraft and the confinement constraints (RNP); Predictions (PRED) 206, to construct an optimized vertical profile on the lateral and vertical trajectory and giving estimates of distance, time, altitude, speed, fuel and wind, in particular on each point, to each control parameter change and at destination, which will be displayed to the crew; - Guiding (GUID) 207, to guide the aircraft in its lateral and vertical planes on its three-dimensional trajectory, while optimizing its speed, 5 with the aid of the information calculated by the Predictions function 206. In an aircraft equipped with a automatic control device 210, the latter can exchange information with the guide module 207; - Digital Data Link (DATALINK) 208 to exchange flight information between Flight Plan / Prediction functions and 10 control centers or other aircraft 209. Figure 3 provides an overview and examples of steps of the process according to the invention. In one embodiment, the information of the flight plan is advantageously centralized within an EFB 300 type device. For example, a function or application "Flight Plan 15 Check & Management" 302 (among other functions or applications 301) called from such an EFB 300 can perform various management operations of the flight plan thus consolidated. In particular, the EFB can transmit, via the aircraft interface 310, the flight plan data, verified and processed, to the FMS 320 (on-board computer integrated with the aircraft). The pilot 20 consults the data and validates in return the different parts of the flight plan. Figure 4 details some examples of steps of the method according to the invention. In particular, the exchanges of information and the gateways between the certified and regulated avionic portion 121 (FMS and 25 interface equipments), schematized by the dotted lines in the figure, and an "open" and non-certified technical environment (EFB) are illustrated in particular. & Flight Planning System). In particular, the figure highlights aspects related to the security and integrity of data reinjected into avionics systems.
    [0004] At step 400, the Flight System Planning (for example that of the airline) transmits (for example via Wifi, 3G / 4G or USB), the operational flight plan within the flight record. The EFB system may for example include a "Flight Plan Check & Management" function which receives the ground data from this "Flight Planning System", ensuring security (encryption or encryption, secure protocol, authentication, etc.) , as well as the integrity of the data (checksum) and also, ensuring that an operator can validate the request if required by the regulations. The manipulated data can be standardized (for example according to ARINC 633). They are usually in a structured XML language format. The EFB collects and centralizes the initial data of the operational flight plan. In step 401, the operational flight plan is encrypted and a hash value is calculated (checksum).
    [0005] In step 402, using a conversion file, the EFB displays the flight plan for the Flight Management System 200. In step 410, the EFB decrypts the data and checks the checksum. the flight plan for the mission preparation and filters the data necessary for the Flight Management System (and / or transmits the pre-filled flight plan reference 20.) At step 411, the flight plan is transmitted to the FMS 200 In step 420, the aircraft interface equipment 310 retrieves the data and checks their coherence according to pre-established rules (for example compliance rules 421) These rules, for example, verify the details of the flight plan. the existence and relevance of the data, etc. In step 430, the aircraft interface equipment 310 emulates a communication protocol of the ACARS (air-ground communication) type, received from a protocol model 431, in order to transmit the flight plan in an avionics protocol and on an avio bus In step 440, the Flight Management System retrieves the flight plan as verified and validated by the certified avionics systems and offers it to the pilot for validation via the EFB. The pilot validates (or not, or partially) the new flight plan by ensuring data consistency between those of the EFB and those from the avionics. In particular, a dedicated display on the EFB can also simulate the processing steps of the avionics equipment: the pilot can compare the data between those displayed on his EFB tablet 300 and those displayed on the avionics equipment 310. The present invention can be implement 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 computer resources can be distributed. 20 25 12
