[0001] The present invention relates to a technology for providing a flight path for an aircraft such as a UAM to fly.

[0002] In the existing aviation system, when an irregular flight plan occurs, the flight operations manager checks the flight plans submitted to the traffic control system to ensure that the flight plans do not overlap with those of other aircraft on the flight path, and submits the flight plans. However, it is inevitable that a lot of time is spent reviewing these flight plans.

[0035] In addition, the input unit (1100) can obtain information on multiple waypoints existing between the departure point and the arrival point, flight plans of other aircraft, etc. from an external device (not shown) such as a control center using wired or wireless communication means.

[0036] In one embodiment, information about the plurality of waypoints may include a preset flight time between the plurality of waypoints, whether a flight is prohibited, etc.

[0037] In one embodiment, the flight plan of another aircraft may include information such as waypoints that constitute the flight path, the time to pass through each waypoint, etc.

[0038] Additionally, the input unit (1100) can obtain a request to select specific flight information from a user terminal using a wired or wireless communication means.

[0039] The candidate flight time calculation unit (1200) can calculate the candidate departure time and candidate arrival time based on the service request.

[0040] In one embodiment, the candidate flight time calculation unit (1200) may determine at least one time within a preset time (e.g., -10 minutes to +10 minutes) from the desired departure time among the times available at the departure location as at least one candidate departure time.

[0041] In one embodiment, the candidate flight time calculation unit (1200) may calculate the minimum flight time between a departure point and an arrival point. For example, the flight path provision device (1000) may calculate the shortest flight path based on preset flight times between multiple waypoints existing between the departure point and the arrival point. The candidate flight time calculation unit (1200) may determine the preset flight time between waypoints forming the shortest flight path as the minimum flight time.

[0042] In one embodiment, the candidate flight time calculation unit (1200) may calculate the shortest flight path by excluding at least one waypoint where flights are prohibited or restricted from among a plurality of waypoints existing between a departure point and an arrival point.

[0043] In one embodiment, the candidate flight time calculation unit (1200) can calculate the shortest flight path by applying a shortest path algorithm such as Dijkstra to a plurality of way points existing between the departure point and the arrival point.

[0044] In one embodiment, the candidate flight time calculation unit (1200) may calculate at least one candidate arrival time based on at least one candidate departure time and a minimum flight time. For example, the candidate flight time calculation unit (1200) may determine at least one candidate arrival time as at least one time period after the minimum flight time elapses from at least one candidate departure time, during which the arrival location is available for landing.

[0045] The candidate flight path generation unit (1300) can generate a candidate flight path based on the candidate departure time and candidate arrival time.

[0046] In one embodiment, the candidate flight path generation unit (1300) may determine at least one flight path, as a candidate flight path, that satisfies at least one candidate departure time and at least one candidate arrival time among flight paths composed of at least one of a plurality of waypoints existing between a departure point and an arrival point. For example, the candidate flight path generation unit (1300) may determine at least one flight path, as a candidate flight path, that departs at at least one candidate departure time and satisfies at least one candidate arrival time after the minimum flight time has elapsed.

[0047] The candidate flight information generation unit (1400) can generate at least one candidate flight information including a flight path, departure time, arrival time, cost, etc. according to at least one candidate flight path.

[0048] In one embodiment, the candidate flight information generation unit (1400) may change a candidate departure time according to at least one candidate flight path, a preset flight time between at least one waypoint constituting at least one candidate flight path, etc., and generate at least one candidate flight information including the changed departure time, arrival time, etc. Accordingly, two or more candidate flight information having different departure times and different flight speeds between waypoints may be generated from one candidate flight path.

[0049] In one embodiment, the candidate flight information generation unit (1400) may determine whether there is a possibility of collision with another aircraft at at least one waypoint when flying along at least one candidate route based on flight information of another aircraft. The candidate flight information generation unit (1400) may change the candidate departure time, the flight time between at least one waypoint constituting the at least one candidate route, etc., so that the time for passing through at least one waypoint with a possibility of collision is different from the time for passing through the at least one waypoint of the at least one candidate route.

[0050] In one embodiment, the candidate flight information generation unit (1400) may assign a weight to at least one of the flight times between waypoints constituting the candidate route, and may change the flight time between waypoints based on the assigned weight. For example, the candidate flight information generation unit (1400) may significantly or slightly change the degree of change in the flight time between waypoints with relatively low weights.

[0051] In one embodiment, the candidate flight information generation unit (1400) can generate candidate flight information including costs by calculating fare costs according to at least one candidate flight route, changed departure time, flight time, etc.

[0052] The recommended flight information decision unit (1500) can decide recommended flight information to be provided to customers, etc. from among candidate flight information based on departure time, arrival time, cost, etc.

[0053] In one embodiment, the recommended flight information determination unit (1500) may determine recommended flight information by weighting departure time. For example, if a flight service request includes a request to prioritize departure time, the flight information with the earliest departure time among the candidate flight information may be determined as the recommended flight information.

[0054] In one embodiment, the recommended flight information determination unit (1500) may determine recommended flight information by weighting arrival time. For example, if a flight service request includes a request to prioritize arrival time, the flight information with the earliest arrival time among the candidate flight information may be determined as the recommended flight information.

[0055] In one embodiment, the recommended flight information determination unit (1500) may determine recommended flight information by weighting cost. For example, if a flight service request includes a request to prioritize cost, the flight information with the lowest cost among the candidate flight information may be determined as the recommended flight information.

[0056] The output unit (1600) can transmit data to an external device (not shown) using a wired or wireless communication means.

[0057] In one embodiment, the output unit (1600) may transmit at least one piece of recommended flight information to a user terminal. Thereafter, when a request to select a recommended flight path is received from the user terminal, the flight path provision device (1000) may determine the recommended flight path as the flight path to be provided to the customer.

[0059] Figure 2 is a flowchart of a flight path providing method according to one embodiment of the present invention.

[0060] Hereinafter, the above method is described as an example performed by the flight path providing device (1000) illustrated in FIG. 1.

[0061] In step S2100, the flight path providing device (1000) can receive a flight service request including a desired departure time, departure location, arrival location, passenger information, etc. from an external device (not shown).

[0062] In one embodiment, the departure location and arrival location may refer to a location where an aircraft can take off and land, such as a vertiport.

[0063] In one embodiment, the external device may be a terminal of a customer who wishes to use an aircraft such as a UAM (hereinafter, a user terminal).

[0064] In step S2200, the flight path providing device (1000) can calculate candidate departure times and candidate arrival times based on the flight service request.

[0065] In one embodiment, the flight path providing device (1000) may determine at least one time within a preset time (e.g., -10 minutes to +10 minutes) from the desired departure time among the times when the departure location is available as at least one candidate departure time.

[0066] In one embodiment, the flight path providing device (1000) may calculate the minimum flight time between a departure point and an arrival point. For example, the flight path providing device (1000) may calculate the shortest flight path based on preset flight times between multiple waypoints existing between the departure point and the arrival point. The flight path providing device (1000) may determine the preset flight times between waypoints forming the shortest flight path as the minimum flight time.

[0067] In one embodiment, the flight path providing device (1000) may calculate the shortest flight path by excluding at least one waypoint where flights are prohibited or restricted from among a plurality of waypoints existing between a departure point and an arrival point. Here, the at least one waypoint where flights are prohibited or restricted may refer to a waypoint included in an area where flights are prohibited by a Notice to Air-mission (NOTAM).

[0068] In one embodiment, the flight path providing device (1000) can calculate the shortest flight path by applying a shortest path algorithm such as Dijkstra to a plurality of way points existing between a departure point and an arrival point.

[0069] In one embodiment, the flight path providing device (1000) may calculate at least one candidate arrival time based on at least one candidate departure time and a minimum flight time. For example, the flight path providing device (1000) may determine at least one candidate arrival time as a time when the arrival location is available for landing among at least one time period after the minimum flight time has elapsed from the at least one candidate departure time.

[0070] In step S2300, the flight path providing device (1000) can generate a candidate flight path based on the candidate departure time and candidate arrival time.

[0071] In one embodiment, the flight path providing device (1000) may determine at least one flight path that satisfies at least one candidate departure time and at least one candidate arrival time among a flight path composed of at least one of a plurality of waypoints existing between a departure point and an arrival point as a candidate flight path. For example, the flight path providing device (1000) may determine at least one flight path that departs at at least one candidate departure time and satisfies at least one candidate arrival time after the minimum flight time has elapsed as a candidate flight path.

[0072] In step S2400, the flight path providing device (1000) can generate at least one candidate flight information including a flight path, departure time, arrival time, cost, etc. according to at least one candidate flight path.

[0073] In one embodiment, the flight path providing device (1000) may change a candidate departure time according to at least one candidate flight path, a preset flight time between at least one waypoint constituting at least one candidate flight path, and the like, and generate at least one candidate flight information including the changed departure time, arrival time, and the like. Accordingly, two or more candidate flight information having different departure times and different flight speeds between waypoints may be generated from one candidate flight path.

[0074] In one embodiment, the flight path providing device (1000) may receive flight information of another aircraft flying at least one waypoint constituting at least one candidate route within a candidate departure time and a candidate arrival time from an external device such as a control tower. The flight path providing device (1000) may determine whether there is a possibility of collision with the other aircraft at at least one waypoint when flying along the at least one candidate route based on the flight information of the other aircraft. The flight path providing device (1000) may change the candidate departure time, the flight time between at least one waypoint constituting the at least one candidate route, etc., so that the time of passing through the at least one waypoint with a possibility of collision is different from the time of passing through the at least one waypoint of the other aircraft. The flight path providing device (1000) may generate candidate flight information including the changed departure time, flight time, etc.

[0075] In one embodiment, the flight path providing device (1000) may assign a weight to at least one of the flight times between waypoints constituting the candidate path, and may change the flight time between waypoints based on the assigned weight. For example, the candidate flight information generating unit (1400) may significantly or slightly change the degree of change in the flight time between waypoints with relatively low weights.

[0076] In one embodiment, the flight path providing device (1000) can generate candidate flight information including costs by calculating fare costs according to at least one candidate flight path, changed departure time, flight time, etc.

[0077] In step S2500, the flight path providing device (1000) can determine recommended flight information to be provided to customers, etc. from among candidate flight information based on departure time, arrival time, cost, etc.

[0078] In one embodiment, the flight path provision device (1000) may determine recommended flight information by weighting departure time. For example, if a flight service request includes a request to prioritize departure time, the flight information with the earliest departure time among the candidate flight information may be determined as the recommended flight information.

[0079] In one embodiment, the flight path providing device (1000) may determine recommended flight information by weighting arrival time.

[0081] In step S2600, the flight path providing device (1000) may transmit at least one piece of recommended flight information to the user terminal. Thereafter, when a request for selecting a recommended flight path is received from the user terminal, the flight path providing device (1000) may determine the recommended flight path as the flight path to be provided to the customer.

[0082]

[0083] Figures 3 to 7 are drawings for explaining a method for providing a recommended path according to one embodiment of the present invention.

[0084] Referring to Figure 3, five waypoints existing between a departure point and an arrival point and the flight times between the waypoints are illustrated. The flight path providing device (1000) can generate a minimum flight path based on waypoints 1 to 4, excluding waypoint 5, which is a no-passage waypoint among the five waypoints.

[0085] Referring to FIG. 4, the flight path providing device (1000) can determine a path with the minimum flight time from the departure point to the arrival point, i.e., a minimum flight path composed of way points 1, 2, and 4, by applying a minimum path algorithm based on the flight time between way points 1 to 4.

[0086] Referring to FIG. 5, the flight path providing device (1000) can determine whether there is a possibility of collision with aircraft 2 when aircraft 1 flies along a candidate flight path. Aircraft 1 departs from the departure point at 10:00 AM and passes through waypoints 1, 2, and 4 to arrive at the destination. Aircraft 2 departs at 10:00 AM and passes through waypoints 3 and 4. Since aircraft 1 is scheduled to arrive at waypoint 4 at 10:15 AM and aircraft 2 is scheduled to arrive at waypoint 4 at 10:16 AM, there may be a possibility of collision at waypoint 4. At this time, the flight path providing device (1000) can calculate a time range in which collision can be avoided at waypoint 4, i.e., an avoidance time range (e.g., -2 minutes to +2 minutes).

[0087] Referring to FIG. 6, the flight path providing device (1000) can change the flight time between waypoints so that the aircraft 1 does not pass through waypoint 4 within the avoidance time range. For example, if the preset flight time from the departure location to waypoint 1 is 5 minutes, the flight path providing device (1000) can change the flight time to 4 minutes. In addition, although not shown in FIG. 6, the flight path providing device (1000) can change the departure time so that the time at which the aircraft 1 passes through waypoint 4 does not fall within the avoidance time range. In this case, the flight path providing device (1000) can generate candidate flight information including the changed flight time, the changed arrival time, the flight path composed of waypoints 1, 2, and 4, etc.

[0088] Referring to FIG. 7, the flight path providing device (1000) can prevent aircraft 1 from passing waypoint 4 within the avoidance time range by changing the departure time. At this time, the flight path providing device (1000) can generate candidate flight information including the changed departure time, arrival time, and the flight path consisting of waypoints 1, 2, and 4.

[0089] In addition, the flight path providing device (1000) can change the path from departure location 1 to waypoint 4 from waypoints 1, 2, and 4 to waypoints 1, 3, and 4 so that the aircraft 1 does not pass waypoint 4 within the avoidance time range. At this time, the flight path providing device (1000) can generate candidate flight information including the changed flight path (waypoints 1, 3, and 4), changed arrival time, etc.
