- the technical field of the invention is that of autonomous aircraft navigation, such as a drone or an airplane equipped with a navigation and automatic guidance system.
- the field of operation is that of remotely operated drones in BVLOS, for the acronym of "Beyond Visual Line of Sight", outside the visual range of a teleoperator, and autonomous aircraft more generally, which may include an airplane initially piloted by a crew who would have lost the ability to pilot (hypoxia, incapacitation of a single pilot, ).
- the aircraft may encounter a certain number of hazards to be dealt with, as illustrated in [Fig.1].
- the objective is to provide safe and autonomous navigation of an aircraft.
- Autonomous navigation means the fact that the aircraft can autonomously modify its navigation in order to adapt either to a modification of the mission or to the vagaries of the mission.
- Safe navigation means the fact that the navigation has a level of criticality corresponding to the risk levels assessed for the mission of the aircraft. It is assumed in this document that the functions other than navigation (propulsion, control surfaces, etc.), have the required levels of criticality with regard to the objectives of flight safety according to the class of the aircraft concerned (drone, commercial aviation, etc.).

- volability of a trajectory refers to the fact that a trajectory is flyable or not; a trajectory being flyable if the aircraft is able to fly this trajectory, i.e. the trajectory is continuous and compatible with the performance of the aircraft.
- the sub-module for checking the flightability of each trajectory is configured to check the adequacy of the trajectory with the technical characteristics of the aircraft representative of the performance of the aircraft comprising technical characteristics representative of aerodynamic performance, propulsion performance, and performance of the navigation and automatic guidance system of the aircraft.
- the sub-module for checking the flightability of each trajectory is configured to use flat rates to estimate the values of the technical characteristics representative of the aerodynamic performance, the propulsion performance, and the performance of the system of navigation and automatic guidance of the aircraft.
- a package quantitatively represents a capacity of the aircraft.
- An example of a forfeit may be the ability to climb with a given vertical speed.
- the flightability verification sub-module for each trajectory is configured to use modeling to estimate the values of the technical characteristics representative of the aerodynamic performance, the propulsion performance, and the performance of the control system. navigation and automatic guidance of the aircraft.

- FIG.7 schematically illustrates the validation of the database comprising a flight mission trajectory and diversion trajectories validated by the analysis and validation module, according to one aspect of the invention.
- the [Fig.2] schematically represents a trajectory selection system of an aircraft provided with an automatic guidance system GA on a trajectory, implemented by computer.
- the system comprises a module for calculating Calc_Traj a flight mission trajectory of the aircraft and diversion trajectories in the event of the occurrence of a hazard during the mission trajectory.
- the system also comprises a TrajDB_Checker analysis and validation module for mission and diversion trajectories present in a TrajDB database, comprising: - a sub-module VV for verifying the volability of each trajectory by verifying the adequacy of the trajectory with the technical characteristics of the aircraft representative of the performance of the aircraft; And
- VA verification sub-module that the diversion trajectories make it possible to respond to a set of determined contingencies, at any time during the mission trajectory.
- the TrajDB database includes a flight mission trajectory and diversion trajectories validated by the TrajDB_Checker analysis and validation module, and is configured to memorize a new flight mission trajectory and new diversion trajectories transmitted by the Calc_Traj calculation module for analysis purposes by the analysis and validation module.
- the TrajDB database is also configured to, in the event of validation of said new flight and diversion mission trajectories by the TrajDB_Checker analysis and validation module, update the validated flight and diversion mission trajectories.
- the system also comprises a module for selecting Sel_Traj the flight trajectory from among the validated flight and diversion mission trajectories, as a function of values of operating parameters of the aircraft making it possible to determine the presence of one of said random, configured to transmit said selected trajectory to the automatic guidance system on a trajectory.
- the Calc_Traj module for calculating a flight mission trajectory of the aircraft and diversion trajectories in the event of the occurrence of a hazard during the mission trajectory performs its trajectory calculations in the open world (no design constraint related to operational safety).
- the Calc_Traj calculation module calculates a set of trajectories corresponding to the trajectory of the mission and all the contingency or diversion trajectories linked to predetermined hazards that may occur during the mission as illustrated in the [Fig.3].
- the Calc_Traj calculation module can recalculate a new set of trajectories during the mission (in the event of modification thereof). This function can be hosted either on the ground in a data center or "data-center” in English or on an on-board computer or "Edge Computer” in English for reasons of latency or availability of the ground link. edge, redundant if necessary, in order to guarantee the availability of the calculation.
- the Calc_Traj calculation module is located on the ground, the new set of trajectories is transmitted to the aircraft via ground/on-board connectivity.
- the C2 link between the drone and its ground station can be used.
- the various means of cockpit and/or cabin connectivity can be used (Satcom, VHF, Air-to-Ground). Specific protocols and gateways (AFCDI type) can be used to update the onboard database with the new set of trajectories.
- this set of trajectories is loaded into a database on board the aircraft and the TrajDB_Checker analysis and validation module checks the set of trajectories. It includes two sub-modules.
- the flightability verification sub-module returns the status OK if the aircraft can actually fly the trajectory (adequacy between the trajectory and the performance of the drone), and returns NOK (for Not OK) otherwise.
- the verification sub-module that the diversion trajectories make it possible to respond to a set of determined contingencies, at any time of the mission trajectory or verification of the contingencies to be processed returns the status OK if the set of trajectories allows you to manage all the predefined hazards until the end of the mission (Concretely, at any time and for any hazard, there is a trajectory compatible with this hazard allowing the mission to be finished). It returns NOK otherwise.
- the TrajDB_Checker analysis and validation module for mission and diversion trajectories calculates a status which can take the following values:
- the TrajDB trajectory database is secure: the TrajDB_Checker analysis and validation module for mission and diversion trajectories returns OK. It allows the aircraft to carry out its mission and to deal with the hazards to be dealt with.
- the TrajDB trajectory database is not secure: the TrajDB_Checker analysis and validation module for mission and diversion trajectories returns NOK. Either one of the trajectories cannot be flown by the aircraft, or there are no trajectories to deal with one of the hazards. [0045] Thus, the return status of TrajDB_Checker is OK only if the statuses of the two sub-functions (checking of the volability and checking of the contingencies to be processed) are OK. In all other cases, the status is NOK.
- the flightability verification function is illustrated in [Fig.5]. This function is called for each database trajectory to be checked. It uses data on the performance of the aircraft: this performance includes aerodynamic performance, propulsion performance (e.g. rate of climb and possible radius of turn) and performance of the navigation and automatic guidance system. This function determines if the aircraft is able to follow the trajectory. For example, if the trajectory includes a slope greater than the maximum rate of climb of the aircraft then the function returns NOK.
- the flightability verification sub-module VV can be implemented using packages to represent the performance of the aircraft and its guidance.
- the function can use a corridor whose size is predefined and returns NOK only if the aircraft can follow its trajectory while remaining in the corridor.
- the sub-module VA for verifying the contingencies to be processed consists of a set of rules to be verified.
- the translation of the hazards into a series of rules is done during the design of the hazard verification sub-module VA.
- the following table gives an example of rules from hazards: These rules will depend on the aircraft in question. For example, the endurance of an aircraft may vary in the event of an engine failure. Some of these rules may require information that must be stored in databases on board the aircraft. For example, it may be necessary to have a database of obstacles in order to verify that no listed obstacle meets a trajectory.
- FIG.6 illustrates the hazard checking function for the three hazards/rules given in the table below.
- the hazard verification sub-module VA can also use the notion of corridor around the trajectory.
- the TrajDB_Checker analysis and validation module for mission and diversion trajectories is designed as an avionics function module hosted by the aircraft. Thus, this module is developed and qualified with the design constraints to ensure the constraints of availability and integrity.
- This TrajDB_Checker analysis and validation module for mission and diversion trajectories is called before each mission and the aircraft cannot take off if the TrajDB trajectory database has not been validated. It is also called each time the TrajDB trajectory database is modified. If the verification fails, then the modification is not accepted and the aircraft remains on the old version of the TrajDB trajectory database. Thus, the aircraft always flies with a valid TrajDB trajectory database. It is in this mechanism, illustrated in [Fig.7], that lies in particular the inventiveness of the solution, because it makes it possible to ensure the autonomy of the aircraft in a safe way (since it has at all times a set of trajectories valid for all the possible hazards of the mission, and this from the initialization of the mission).
- the on-board Sel_Traj flight path selection module chooses the correct path from among the paths in the TrajDB database throughout the mission. This decision-making integrates the operational logics as a pilot on board would have done. It uses the sensors present on board the aircraft in order to identify hazards and possibly change trajectory. In particular, the flight path selection module Sel_Traj can pass on a path diversion depending on the hazard(s) identified. It is also an avionics function module hosted by the aircraft.
- the navigation and automatic guidance system SNGA makes it possible to guide the aircraft along the chosen trajectory. It is an avionics function module hosted by the aircraft.
- a function module, on board the aircraft, for calculating trajectories associated with a database of flight plans determined in the open world can be inserted between calls from the Sel_Traj flight path selection module and SNGA automatic navigation and guidance system on a path.
- the flight plans obtained can be based on the information published in an A424 navigation database (capacity adapted to commercial aviation flights to fit into the General Air Traffic (GAT) for example) or on free routes , not constrained by existing procedures (capacity adapted to drone-type missions following a gas pipeline, for example).
- the system according to the invention allows safe and autonomous navigation, because the TrajDB trajectory database being validated by an avionics function module TrajDB_Checker, for any hazard, there is a validated trajectory to complete the mission. This trajectory is executed by avionic function modules.
- the trajectories are calculated in the open world, it is therefore possible to use all the resources of the open world to obtain mission trajectories.
- the aircraft is a drone carrying out an inspection mission of a power line or a gas pipeline, it is possible to use the operator's GIS (Geographic Information System) in order to calculate these trajectories. It is also possible to adapt the trajectory calculation to a new type of mission or to improve the calculation of the trajectories without modifying the avionic functions of the aircraft.
- GIS Geographic Information System
- the trajectories can also be calculated on a platform on board the aircraft (but not avionics), this makes it possible to update the database of trajectories during the mission and to use the sensors of the aircraft as input data for the trajectory calculation. It can be used for tracking missions of a moving target, in this case, the trajectories depend on the sensors allowing the tracking of the target (for example an optronic ball) and are calculated at a high frequency (a few seconds). It is also possible to use this calculation on board for an aircraft avoidance function: if a conflict with traffic, or a meteorological event is detected by the sensors of the aircraft (camera type) then a new calculation trajectory is triggered in order to avoid this conflict.
- the present invention can be applied to any aircraft and in particular to
