    IMPLEMENTATION OF THE FLIGHT PATH i
    Flight path management system
    The present invention relates generally to the determination of the flight paths of aircraft, and more particularly to the determination of the flight path of an aircraft to a moving target.
    Aircraft operators often want aircraft to fly around an area of interest (eg wreckage, accident site) to perform a search and rescue and / or surveillance mission. The flight path around such an area of interest may include a closed loop route, with a radial distance from the area of interest. Thus, the aircraft can maintain a precise distance from the area of interest while it is carrying out its mission. In addition, if the area of interest is hostile, the aircraft can fly at a safe distance from the area of interest.
    Aspects and advantages of embodiments of the present disclosure will be set forth in part in the description below or will emerge from the description or will appear upon the practice of the embodiments.
    An example of an aspect of this disclosure relates to a computer-executed method for determining an aircraft flight path. The method may include identifying, by one or more computer devices associated with an aircraft, one or more parameters associated with a moving target. The method may further include determining, by the computer device (s), a mobile circular flight trajectory associated with the mobile target, so that the mobile target is surrounded by the mobile circular flight trajectory, on the basis, at least in part, of the parameter or parameters associated with the moving target. The method may include identifying, by the computer device (s), one or more states associated with at least the aircraft or the mobile circular flight path. The method may also comprise the determination, by the computer device (s), of a flight path of the aircraft, from a position of the aircraft to the mobile circular flight path, based on , at least in part, of the parameter or parameters associated with the moving target and of the state or states associated at least with the aircraft and with the mobile circular flight trajectory.

    FIG. 8 represents an example of a system in accordance with examples of embodiments of the present disclosure.
    Reference will be made below in detail to embodiments of the present disclosure, one or more examples of which are illustrated in the drawings. Each example is given by way of explanation of this disclosure, without being limiting. In fact, those skilled in the art will understand that various modifications and variants can be made to the present disclosure without departing from the scope or the spirit of the invention. For example, properties that are illustrated or described as part of one embodiment can be used with another embodiment to result in yet another embodiment. Thus, the present disclosure aims to encompass such modifications and variations, insofar as they are within the scope of the appended claims and their equivalences.
    Examples of aspects of this disclosure relate to systems and methods for determining a flight path of an aircraft to a circular moving flight path around a moving target. For example, an aircraft flight management system (FMS) can identify a moving target and / or be supplied with identification data of a moving target of interest (for example a ship, another aircraft ). The moving target can be a target for which surveillance is desired or which requires assistance or refueling, etc. The flight management system can determine one or more parameters associated with the moving target (for example position, course, speed). The flight management system can then identify a mobile circular flight path surrounding the target, so that the target is inside (for example in the center) of the circular flight path. The circular flight path may move laterally (for example, in accordance with the target's course, speed, and the like), so that the target remains within the circular flight path, as the target moves. The flight management system can determine the optimal flight path from an aircraft position to the circumference of the moving circular flight path around the moving target. The optimal flight path can provide the minimum time required for the aircraft to move from its position to the circular flight path. Once on the circular flight path, the aircraft can fly along the circular flight path, so as to move around the target (for example for surveillance purposes) with a certain radius. Thus, the present disclosure can provide an automated flight system, with an effective flight path for search and rescue of a moving target, aerial surveillance of ships / vehicles in motion whose position and speed are known, the control of unmanned vehicles (UAS / UAV), interception and monitoring of extreme moving weather conditions, hostile targets etc., keeping a safe distance.
    More particularly, an aircraft may include a computer system and a display system. The computer system can for example be associated with a flight management system. The display system can for example be associated with a control and display system. In some embodiments, the flight management system can determine the optimal flight path for an aircraft, from its position (e.g. current position or future position) to a mobile circular flight path , surrounding a moving target. The moving target can be a vehicle, a ship, an aircraft, an unmanned aircraft, an individual weather system or the like, which is in motion.
    The flight management system can be configured to identify one or more parameters associated with a moving target. The parameter (s) may include the initial position of the moving target, a course of the moving target (for example the trajectory followed by the target), a speed of the moving target, a speed vector of the moving target, an altitude of the moving target, a target type, an entity associated with the target and / or other parameters associated with the moving target. In certain implementation modes, the flight management system can be configured to receive a set of data indicating the parameter or parameters associated with the moving target, coming from one or more data processing devices (for example a control center on the ground), which are not on board the aircraft.
    The flight management system can be configured to determine a mobile circular flight path associated with the mobile target so that the mobile target is within the mobile circular flight path. The mobile circular flight trajectory can represent a circular course (for example of surveillance) around the mobile target (for example a ship). The mobile circular flight path associated with the target can move so that the target remains in the center. For example, in the case where the moving target is a ship, the moving circular flight path can move laterally, in accordance with a motion vector which is at least similar to the lateral movement of the ship. In certain embodiments, the flight management system can receive a set of data indicating the mobile circular flight trajectory associated with the mobile target, coming from the data processing device (s) (which are not, for example, on board the 'aircraft).
    On the other hand, the flight management system can be configured to identify one or more states associated at least with the aircraft and / or the mobile circular flight path. For example, the flight management system can identify the momentary atmospheric flight conditions which the aircraft is undergoing or will undergo during the flight, information relating to the performance of the aircraft, the motion vector of the mobile circular flight path and other. The flight management system can identify these conditions by communicating with different on-board systems (for example sensors, data acquisition systems) and / or a remote computer system (for example the operations center, the meteorological center ).
    The flight management system can determine an aircraft flight path from a position of the aircraft to the mobile circular flight path based, at least in part, on the parameter (s) associated with the moving target and the state or states associated at least with the aircraft and the mobile circular flight path. The flight path can be an optimal lateral flight path to intercept a circumference of the mobile circular flight path. For example, the flight path can be determined in order to reduce a journey time (t2-ti) of the aircraft to move from its position to the mobile circular flight path. In certain embodiments, the flight path can represent a flight path with minimum lateral time from the position of the aircraft to the circumference of the mobile circular flight path, as described below.
    The flight management system can be configured to provide the determined flight path for viewing and acceptance. For example, the flight management system can be configured to generate output data indicating the flight path, and to provide a visualization of the output data indicating the flight path of the aircraft. The control and display system can be configured to display the output data indicating the flight path of the aircraft, for display on a user interface of a display device. A user (such as an operator or an aircraft crew member) can check and accept the flight path from the position of the aircraft to the mobile circular flight path. Acceptance of the flight path can be notified to the flight management system, which can implement the flight path so that the aircraft is moving along the flight path.
    The systems and methods according to exemplary aspects of this disclosure provide an aircraft with an optimal lateral flight path latéraleο to effectively intercept a moving circular flight path around a moving target of interest. In particular, the optimal flight path can increase fuel savings by performing the flight in accordance with a precise distance, time, flight path and fuel combustion predictions used for advance mission planning. On the other hand, systems and methods can reduce the operator's workload, thus allowing him to focus on the real-time conditions of a mission (for example for aircraft with and without pilot and / or crew ). Thus, the systems and methods according to exemplary aspects of the present disclosure have a technical effect by indicating flight paths which are efficient in terms of time and fuel for missions, which can unpredictably reduce wear and tear and the mission of the aircraft, while also increasing safety.
    FIG. 1 illustrates an example of a system 100 in accordance with exemplary embodiments of the present disclosure. As shown, the system 100 may include an aircraft 110 having one or more engines 112, a fuselage 114, a display system 115 and a computer system 116.

    In certain implementation modes, the display system 115 can be located at a distance from the aircraft 110. For example, the aircraft 110 can be associated with an unmanned vehicle control (UAS / UAV). The aircraft 110 can be controlled via communications with the data processing device (s) 130. The display system 115 can be associated with one or more data processing devices of this type. The computer system 116 can be configured to communicate with the display system 115 (for example to execute some of the operations described here), via the network 132.
    FIG. 2 schematically represents examples of flight paths in accordance with exemplary embodiments of the present disclosure. The computer device (s) 119 can be configured to identify a moving target 202. The moving target 202 can include a moving vehicle, ship, aircraft, unmanned aircraft, individual weather system, etc. For example the moving target 202 can move from an initial position 204 (for example 36 degrees of latitude - 73 degrees of longitude) to a second position 206 (for example 35 degrees of latitude - 74.5 degrees of longitude) The moving target 202 can continue to move (for example beyond the second position). In some embodiments, the computing device (s) 119 can be configured to identify the moving target 202 without communicating with other systems. In certain implementation modes, the computer device (s) 119 can be configured to identify the mobile target 202 on the basis, at least in part, of communications with the on-board system (s) 120 and / or the data processing device (s) 130 For example, the data processing device (s) 130 may be associated with an operational entity, a command center, a mission control center, a ground-based center, a friendly aircraft or the like. The computer device (s) 119 can be configured to receive a set of data indicating the moving target 202, coming from the data processing device (s) 130.
    The computer device (s) 119 can be configured to identify one or more parameters 208 associated with the moving target 202. The parameter (s) 208 can include the initial position 204 (for example the latitude and longitude) of the moving target 202, a heading 208A of the moving target 202, a speed 208B of the moving target 202, a speed vector 208C of the moving target 202, a reference time 208D associated with the moving target 202 (for example an observation time, a time where target 202 is in its initial position), a course of the moving target 202, an altitude of the moving target 202, a type of target, an entity associated with the target and / or other parameters associated with the moving target 202 In certain implementation modes, the computer device (s) 119 can be configured to identify the parameter (s) 208 without communicating with other systems. In certain implementation modes, the computer device (s) 119 can be configured to receive a set of data 210 indicating the parameter (s) 208 associated with the moving target 202, coming from the data processing device (s) 130.
    The computer device (s) 119 can be configured to determine a mobile circular flight trajectory 212 associated with the mobile target 202. The mobile circular flight trajectory 212 can be associated with a flight trajectory along which the aircraft 110 can move around from the moving target 202, at a constant distance or with a constant radius 214, as the moving target 202 continues to move. The movable circular flight path 212 may surround the movable target 202. The movable target 202 may be inside the movable circular flight trajectory 212. In certain embodiments, the radius 214 of the flight trajectory mobile circular 212 can be programmed to change so that the distance between the mobile target 202 and the aircraft 110 (which moves for example following the mobile circular flight path 212) can increase and / or decrease. In certain implementation modes, the flight path for the aircraft 110 can be determined to adapt to a change in radius 214. The mobile circular flight path 212 can be used for example to monitor a mobile target 202. Although FIG. 2 indicates the circular mobile flight trajectory 212 clockwise, this is not intended to be limiting, and the mobile circular flight trajectory 212 could also be move in another direction (for example anticlockwise).
    The mobile circular flight path 212 can surround the mobile target 202. In certain embodiments, the mobile target 202 can be inside the mobile circular flight path 212. For example, the aircraft 110 can determining the mobile circular flight path 212 associated with the mobile target 202, so that the mobile target 202 can be located inside (for example at the center 216) of the mobile circular flight trajectory 212, on the basis , at least in part, of the parameter or parameters 208 associated with the mobile target 202. Thus, the mobile circular flight trajectory 212 can move in accordance with a motion vector 217. This motion vector can be at least similar to an associated motion vector to the moving target 202 and / or in relation to it.
    For example, the computer device (s) 119 can identify a ship as a moving target 202. The computer device (s) 119 can establish that the initial position 204 of the ship is 36 degrees latitude, - 73 degrees longitude , that the ship's initial heading 208A is 225 degrees and that the ship's speed 208B is 32 knots. The computer device (s) 119 can determine the mobile circular flight path 212 on the basis, at least in part, of these parameters, so that the ship is inside the mobile circular flight path 212, as it moves. The mobile circular flight path 212 can move following the movement vector 217, at a speed which matches that of the ship. On the other hand, the computing device (s) 119 can determine the radius 214 of the mobile circular flight path 212. This can be based, at least in part, on the type of moving target, weather conditions, other aircraft in the area, aircraft performance, type, etc.
    The computer device (s) 119 can be configured to identify one or more states 218 associated at least with the aircraft 110 and / or with the mobile circular flight path 212. The state (s) 218 can include one or more initial states and / or one or more predicted states. The predicted state or states may include the position of the aircraft, the course of the aircraft, the true speed, the current wind vector, the current weather, the performance of the aircraft, the limitation of the angle of inclination. lateral, the central point (for example 216) of the mobile circular flight path 212, a turning radius, the movement vector 217, the reference time 208D, etc. The reference time can also and / or as a variant be associated with a past and / or future time and / or it can indicate a time when the mobile circular flight trajectory 212 begins to move along the motion vector 217. The or the predicted states may include states in which the aircraft will be at a future time, for example when the aircraft is moving along the mobile circular flight path 212. By way of example, the predicted state or states may include a planned gear change. This may include an acceleration or deceleration which can be programmed to occur before joining the mobile circular flight path 212. The effect of the speed change on the time-based solution can be predicted by the device (s) 119 and can be taken into account.
    The computer device (s) 119 may be configured to determine a flight path 220 of the aircraft 110, from a position 222 of the aircraft 110 to the mobile circular flight path 212, on the base, at at least in part, of the parameter or parameters 208 associated with the mobile target 202 and / or of the state or states 218 associated at least with the aircraft 110 and / or with the mobile circular flight trajectory 212. The position 222 can be a position current and / or future position. For example, the aircraft 110 can move to fulfill another mission, but can plan in advance to follow a flight path from a future position (for example associated with the other mission) until the mobile circular flight path 212. The flight path 220 can be an optimal lateral flight path to intercept a circumference 224 of the mobile circular flight path 212. The flight path 220 can be determined to reduce a travel time (t2 -ti) for the aircraft 110 in order to move from position 222 to the mobile circular flight path 212. In certain embodiments, the computer device (s) 119 can determine the flight path 220, from so that it represents a flight path with minimum lateral time from the position 222 of the aircraft to near the circumference 224 of the flight path flown re mobile 212, as described below.
    As shown in FIG. 2, in certain modes of implementation, the flight path 220 can comprise one or more segments 226A to 226B. For example, the flight path 220 may include a first segment 226A and / or a second segment 226B. The first segment 226A of the flight path 220 may be associated with a first trajectory from the current position 222 and up to the proximity of a circumference 224 of the mobile circular flight path 212. The first segment 226A may include a substantially straight segment from the aircraft 110, for example, and following the heading to an area located in the vicinity of a point of intersection 250 with the mobile circular flight path 212. In addition, and / or as a variant , the first segment 226A can be associated with a geodetic line, the shortest path distance on the ground, etc. The second segment 226B can be associated with a second trajectory to orient the aircraft 110 so that it travels following the mobile circular flight trajectory 212. For example, the second segment 226B can comprise a curved trajectory, such as a transition turn 230 around the intersection point 250, which joins the mobile circular flight path 212.
    Although Figure 2 shows the flight path 220 from a position outside of a circumference 224 of the mobile circular flight path 212, this should not be interpreted as being limiting. In certain embodiments, the computer device (s) 119 can determine the flight path 212 from a position 222 inside the circumference 224 of the mobile circular flight path 212 (for example at the within the limits of the trajectory).
    The computer device (s) 119 may be configured to generate output data indicating the flight path, for viewing. For example, FIG. 3 represents a part of the example of the system 100 according to exemplary embodiments of the present disclosure. As shown, the computer device (s) 119 can generate output data 302 indicating the flight path 220 of the aircraft 110. In addition, and / or as a variant, the output data 302 can indicate the moving target 202, the mobile circular path 212, the parameter (s) 208, the state (s) 218 and / or other data. The computer device (s) 119 can be configured to provide a display of the output data 302 indicating the flight path 220 of the aircraft 110 on a user interface 304 of a display device 117.
    The display device 117 can receive the output data 302 and display at least the flight path 220 of the aircraft 110 on the user interface 304. For example, the display device 117 (associated for example with the control system and display 115) can display at least the flight path 220 of the aircraft 110 on the user interface 304, for a user associated with the aircraft 110 (for example a remote operator or a member of the crew of the aircraft). 'aircraft). The user can interact with the display device 117 and / or another device, via an input device (for example a microphone, a mouse, a touch screen or a trackball) to accept and / or reject the flight path
    220. In the case where the flight path 220 is accepted, the display device 117 can receive a set of data 306 indicating the acceptance of the flight path 220 (for example via input by the user). The display device 117 can provide, and the computer device (s) 119 can receive, a set of data 308 indicating an acceptance of the flight path 220, via the user interface 304.
    The computer device (s) 119 can be configured to execute the flight path 220, so that the aircraft 110 moves along the flight path 220. For example, the computer device (s) 119 can be configured to set implementing the flight path 220 via the flight management system and / or the automatic pilot system of the aircraft 110. After the implementation, the aircraft 110 can move along the first segment 226A from the flight path 220, to near the circumference 224 of the mobile circular flight path 212, and following the second segment 226B, until the transition to flight along the mobile circular flight path 212. In certain modes of implementation, at the end of the transition turn 230 of curved trajectory, the lateral piloting control can pass from the traditional piloting with rectilinear and curved segments to te specific piloting techniques for positioning on and following the mobile circular flight path 212. When aircraft 110 follows this mobile circular flight path 212, it moves circularly and laterally, in a manner which is similar to the example of flight path 402 in diagram 400 shown in FIG. 4.
    FIG. 5 represents a flow diagram of an example of a method 500 for determining a flight path, in accordance with exemplary embodiments of the present disclosure. FIG. 5 can be implemented by one or more computer devices, for example the computer device (s) 119 illustrated in FIGS. 1 and 8. One or more steps of the method 500 can be executed during the flight of the aircraft 110. On the other hand, Figure 5 shows steps performed in a particular order, for purposes of illustration and explanation. Those skilled in the art using the disclosures disclosed herein will understand that the various steps of the methods described herein can be modified, adapted, extended, reorganized and / or omitted in various ways, without departing from the scope of the present invention.
    In (502), the method can include identifying a moving target. For example, the computer device (s) 119 can identify the moving target 202. As described above, the computer device (s) 119 can identify the moving target 202 by one or more communications with the data processing device (s) 130 (for example a center mission control, command center, ground-based center). In addition, and / or alternatively, the computer device (s) 119 can identify the moving target 202 without communicating with other systems.
    In (504), the method can include identifying one or more parameters associated with the moving target. For example, the computer device (s) 119 on board the aircraft 110 can identify one or more parameters 208 associated with the moving target 202. As described above, the parameter (s) 208 can include an initial position 204 of the moving target 202 , a heading 208A of the moving target 202, a speed 208B of the moving target 202, and a reference time 208D associated with the moving target 202. The computer device (s) 119 can identify the parameter (s) 208 by communicating with one or more several data processing devices 130. For example, the data processing device (s) 119 can receive a set of data 210 indicating the parameter (s) 208 associated with the moving target 202, coming from one or more data processing devices 130 which are not on board the aircraft 110.
    In (506), the method may include determining a mobile circular flight path associated with the mobile target. For example, the computer device (s) 119 can determine a mobile circular flight path 212 associated with the mobile target 202, so that the mobile target 202 is surrounded by the mobile circular flight trajectory 212, on the base, at the at least in part, of the parameter (s) 208 associated with the moving target 202. The moving circular flight path 212 associated with the moving target 202 can move laterally, so that the moving target 202 remains inside (by example in the center) of the mobile circular flight path 212. For example, the computer device (s) 119 can determine the mobile circular flight path 212, based, at least in part, on the initial position 204 (for example 36 latitude (73 degrees longitude) of moving target 202, heading 208A (e.g. 270 degrees) of moving target 202 and speed 208B (e.g. 32 knots) of moving target 202 (for example a ship) and / or a reference time 208D. The mobile circular flight trajectory 212 can be determined so that a radius of the mobile circular flight trajectory 212 is associated with a safety distance for the aircraft 110 when it is moving along the flight trajectory mobile circular flight 212. In certain embodiments, the computer device (s) 119 can determine the mobile circular flight trajectory 212 by receiving a set of data indicating the mobile circular flight trajectory 212, coming from one or more devices data processing 130.
    In (508), the method can include identifying one or more states associated with at least the aircraft and / or the mobile circular flight path. The computer device (s) 119 can identify one or more states 218 associated at least with the aircraft 110 and / or with the mobile circular flight path 212. In certain embodiments, the state (s) 218 can include states initials and / or predicted states. For example, the computer device (s) 119 can identify the momentary atmospheric flight conditions which the aircraft 110 is undergoing or will undergo during the flight, the information relating to the performance of the aircraft, the motion vector 217 of the circular flight path mobile 212 and other states.
    In (510), the method may include determining a flight path for the aircraft. The computer device (s) 119 can determine a flight path 220 of the aircraft 110, from a position 222 of the aircraft 110 to the mobile circular flight path 212, based, at least in part , of the parameter (s) 208 associated with the moving target 202 and / or of the state (s) 218 associated at least with the aircraft 110 and / or with the mobile circular flight trajectory 212. For example, the flight trajectory 220 of the the aircraft 110 can be determined to reduce the travel time (for example t2-ti) of the aircraft 110 to move from position 222 (for example current or future) to the mobile circular flight path 212. The flight path 220 can be associated with an optimal lateral flight path from position 222 to the mobile circular flight path 212 which is associated with the minimum time necessary for the aircraft 110 to reach (and / or join) the trajectory of v ol mobile circular 212 from position 222 of the aircraft.
    By way of example, the computer device (s) 119 can use the curvature of the earth, together with the state (s) 218 (for example the initial states, the predicted states) to find an estimated minimum time, at the end of which the aircraft 110 will join the mobile circular flight path 212. This estimated minimum time can be used to find a point of intersection 250 which can be the point where the flight trajectory 220, to join the mobile circular flight trajectory 212, cuts the circumference 224 of the mobile circular flight path 212. The minimum estimated time and the point of intersection 250 can be refined to take account of the effects of the wind on the ground speed of the aircraft 110, of the time to make the turn 230 so to join the mobile circular flight path 212, a planned speed change and / or other factors. In addition, and / or as a variant, a wind vector and a predicted course of the aircraft along a potential flight path can be used to predict the ground speed of the aircraft at several given times (for example seconds, milliseconds etc.).
    The flight path 220 (for example an optimal flight path) can then be established. For example, the flight path 220 may include a first segment 226A and a second segment 226B. The first segment 226A of the flight path 220 can be associated with a first trajectory starting from the current position 222, up to the proximity of a circumference of the mobile circular flight path 212. The second segment 226B can be associated with a second trajectory for orienting the aircraft 110 so that it travels following the mobile circular flight trajectory 212. The first segment 226A can for example comprise a rectilinear (and / or substantially rectilinear) segment, starting from the aircraft 110 and following the heading up to the point of intersection 250. The second segment 226B may for example comprise a curved trajectory, with a transition turn 230 around the point of intersection 250, which joins the mobile circular flight trajectory 212. The curved trajectory can join the mobile circular flight trajectory 212 at an angle which takes into account the effect of the drift angle of the movement of the trajectory. mobile circular flight and / or flight speed of the aircraft at the instant of intersection. As described above, at the end of the curve trajectory transition turn, the lateral piloting command of the aircraft 110 can pass from traditional piloting with rectilinear and curved segments to piloting techniques intended to execute the mobile circular flight trajectory. 212.
    The computer device (s) 119 can be configured to determine the flight path 220, based, at least in part, on one or more parameters 208 and / or on a state or states 218 updated. day. For example, one or more of the parameters 208 (for example the speed of the target 208B) and / or states 218 (for example the effect of the wind) can change over time. The computer device (s) 119 can receive one or more updates of at least one of the parameters 208 and / or states 218. In certain implementation modes, the computer device (s) 119 can receive the updates so periodic (for example every 5, 10, 15, 30, 60 s), on request, continuous or other. The computer device (s) 119 can determine the flight path 220 of the aircraft 110, based, at least in part, on at least one of the updated parameters and / or the updated states. Thus, the computer device (s) 119 can take into account changes in parameters and / or states, when they determine the optimal flight path.
    FIG. 6 illustrates an example of a method 600 for determining a flight path in accordance with exemplary embodiments of the present disclosure. In certain modes of implementation, the method 600 can be practiced in (510) of the method 500. FIG. 6 can be implemented by one or more computer devices, for example the computer devices 119 illustrated in FIGS. 1 and 8. One or more steps of method 600 can be performed during the flight of aircraft 110. In addition, Figure 6 shows steps performed in a particular order, for purposes of illustration and explanation. Those skilled in the art using the disclosures disclosed herein will understand that the various steps of any of the methods described herein can be modified, adapted, extended, reorganized and / or omitted in different ways, without departing from the scope of the present invention.
    In (602), the method 600 can comprise the calculation of the initial position of the mobile circular flight trajectory. For example, the computer device (s) 119 can calculate the initial position of the mobile circular flight path 212. In certain embodiments, the initial position of the mobile circular flight path 212 can be associated with the initial position 204 (for example 36 degrees latitude - 73 degrees longitude) of the moving target 202. As indicated above, a reference time (for example 208D) associated with the moving circular flight path 212 can indicate the moment when the movement of the mobile circular flight path 212 begins (for example, an instant when the mobile circular flight path 212 begins to move along the motion vector 217).
    In (604), method 600 may include determining whether the aircraft is inside or outside the mobile circular flight path. For example, the computer device (s) 119 can determine whether the aircraft 110 is inside or outside the mobile circular flight path 212, when it is in position 222 and / or in a other position. In the event that it is determined that the aircraft 110 is inside the mobile circular flight path 212, the computer device (s) 119 can establish a flight path 220 (for example an optimal interior lateral flight path ) to the mobile circular flight path 212, from a position inside the mobile circular flight path 212, at (606). In the event that it is determined that the aircraft 110 is outside the mobile circular flight path 212, the computer device (s) 119 can establish a flight path 220 (for example an optimal exterior lateral flight path ) toward the mobile circular flight path 212, from a position outside the mobile circular flight path 212, at (608).
    FIG. 7 illustrates an example of a method 700 of constructing a flight path of the aircraft in accordance with exemplary embodiments of the present disclosure. In certain modes of implementation, the method 700 can be practiced in (606), (608), (616) and / or (618) of the method 600. FIG. 7 can be implemented by one or more computer devices, for example computer devices 119 illustrated in FIGS. 1 and 8. One or more steps of the method 700 can be executed while the aircraft 110 is in flight. In addition, Figure 7 shows steps performed in a particular order, for purposes of illustration and explanation. Those skilled in the art using the disclosures disclosed herein will understand that the various steps of any of the methods described herein can be modified, adapted, extended, reorganized and / or omitted in different ways, without departing from the scope of the present invention.
    In (702), the method 700 can comprise the calculation of the ground speed of the aircraft along the current trajectory. For example, the computer device (s) 119 can calculate a ground speed of the aircraft 110 along the current trajectory of the aircraft 110. Thus, the calculation of the ground speed can be based, at least in part, on a or several of the states 218, such as the wind vector to which the aircraft 110 is subjected. In (704), the computer device (s) 119 can calculate the minimum estimated time necessary for the aircraft 110 to reach the circumference 224 of the trajectory of mobile circular flight 212 and / or the point of intersection 250 (for example a point where the flight path of the aircraft intersects the mobile circular flight trajectory 212). This may be based, at least in part, on whether the aircraft 110 is inside or outside the mobile circular flight path 212. At (706), the computer device (s) 119 can repeat the calculations in (702) and / or (704) to refine the minimum time and the point of intersection 250 and to take into account, for example, the predicted trajectory of the aircraft and the ground speed along the flight path 220, to the point of intersection 250. This can allow the computing device (s) 119 to take into account the potential changes associated with the aircraft 110 (and its states) along the flight path 220.
    In (708), method 700 may include constructing a transition turn around the point of intersection. For example, the computer device (s) 119 may determine the transition turn 230 around the point of intersection 250 (for example which joins the mobile circular flight path 212), based, at least in part, on the effect angle of drift of the movement of the mobile circular flight path 212 and of the predicted ground speed of the aircraft at the instant of intersection. In (710), the computer device (s) 119 can refine the minimum time and the point of intersection 250, based, at least in part, on the time required to execute the transition turn 230, the effects of the wind associated with the transition turn, planned speed changes associated with the execution of transition turn 230 and / or other factors. The computer device (s) 119 can reconstruct the transition bend 230 around the refined intersection point 250, at (712). This can be used to obtain a more precise determination of the transition turn 230 that the aircraft 110 will have to execute in order to appropriately join the mobile circular flight path 212.
    In (714), the method 700 can comprise the detection of abnormal scenarios of mobile circular flight trajectory. For example, the computing device (s) 119 can determine abnormal scenarios associated with the mobile circular flight path 212. For example, the computing device (s) 119 can determine whether the moving target 202 is moving at a speed greater than that of the aircraft 110, which makes it difficult for the aircraft 110 to reach the mobile circular flight path 212.
    Referring again to Figure 6, at (610), the method 600 may include adjusting the inputs for the mobile circular flight path 212. For example, the computer device (s) 119 can adjust all of the parameters associated with the mobile circular flight path 212, used to establish the flight path 220, as necessary, to take into account the effect of time when the movement of the mobile circular flight path 212 begins (e.g. reference time 208D ). In (612) to (618), in the case where the inputs are adjusted, the computer device (s) 119 can reconstruct the flight path 220, based, at least in part, on the fact that the aircraft 110 is inside or outside the mobile circular flight path 212. In (620), the computer device (s) 119 can process the abnormal scenarios associated with the mobile circular flight path 212. For example, the computer devices 119 can adjust the route and / or the speed of the aircraft 110, so that the aircraft 110 is capable of reaching the mobile circular flight path 212, in the event that the mobile target 202 is moving at a speed higher than that of aircraft 110.
    Returning to FIG. 5, at (512), the method may include the generation of output data indicating the flight path of the aircraft. For example, the computer device (s) 119 may generate output data 302 indicating the flight path 220 of the aircraft 110. At (514), the method may include providing visualization of the output data indicating the path flight. For example, the computer device (s) 119 can provide a display of the output data 302 indicating the flight path 220 of the aircraft 110 on a user interface 304 of a display device 117. As described here, the display device 117 may be on board the aircraft 110 and / or be located at a distance from the aircraft 110. In certain implementation modes, a user can interact with the user surface 304 to accept the flight path 220 determined by the or IT devices 119.
    In some embodiments, in (516), the method may include receiving acceptance of the flight path. The computer device (s) 119 can receive a data set 308 indicating that the flight path 220 is accepted. This can take place, for example, when a user (for example a member of the aircraft crew, a remote operator) associated with the display device 117 accepts flight path 220.
    In (518), the method can include implementing the flight path. For example, the computing device (s) 119 can execute the flight path 220, so that the aircraft 110 moves in accordance with the flight path 220. The aircraft 110 can move in accordance with the first segment
    226A to arrive at the mobile circular flight path 212, and in accordance with the second segment 226B to join the mobile circular flight path 212. Thus, the aircraft 110 can move in the direction of the mobile circular flight path 212 and in accordance with this, in an efficient and time-appropriate manner.
