And 5, calculating the minimum flight path deviation path and the maximum flight path deviation path of the aircraft in the conflicting flight paths by combining the performance of the aircraft and the environmental information of the conflicting flight paths.
In the embodiment of the invention, the minimum route deviation path refers to the shortest path from the aircraft to the original route after deviating from the original route; the maximum route deviation path refers to the longest path of the aircraft returning to the original route after deviating from the original route.
In an embodiment of the invention, a minimum lane departure path and a maximum lane departure path of the aircraft in a secondary lane or a combination of secondary lanes are calculated.
In the embodiment of the invention, the area between the minimum route deviation path and the maximum route deviation path in each sub-route or each sub-route combination is used as the deviation-capable range, and a plurality of deviation-capable ranges are obtained.
In a specific implementation, the aircraft returns to its original route again after deviating in its degree of freedom, which is particularly affected by flight tasks, aircraft performance, specific conflicts and its surrounding environment, the range and power performance indexes of the aircraft are different, and the trajectory arcs deviating from the flight path are also different, for example, when the aircraft turns, climbs, lowers and the like, its deviation route angle and regression route angle are limited, and the corresponding route deviation path can be calculated through simulation, it should be noted that, no matter the minimum or maximum route deviation path, it may be a plurality of paths, or not necessarily two-dimensional, or three-dimensional, because the aircraft can deviate from multiple degrees of freedom, and the finally formed range that can deviate may be a three-dimensional range, and thanks to the three-dimensional dynamic image generation technology, the user can visually observe the range that the aircraft can deviate.
In specific implementation, the lane deviation path is calculated for two conflicting sub-lanes at the same time, and then corresponding deviation ranges can be obtained for the two conflicting sub-lanes.
In a specific implementation, besides on conflicting sub-routes, the corresponding deviation paths may be calculated on the basis of other sub-routes or a plurality of sub-route combinations on two conflicting flight routes, and of course, even if the calculation is based on a sub-route combination, the combination is mainly based on a conflicting sub-route, for example, two sub-routes are merged to calculate the corresponding minimum route deviation path and maximum route deviation path, so that more options are provided, and all deviation areas based on different sub-routes or combinations can be visually observed on a three-dimensional dynamic image to avoid conflicts with other routes which may occur or are potential after the routes are adjusted, or to meet special requirements of air planning, and the like.

In the embodiment of the invention, in a plurality of deflectable ranges, a path which enables the distance between conflicting sub-routes to be larger than a standard safety distance is calculated to be used as a minimum adjusting route, a path which enables no route conflict to exist between the sub-route and other sub-routes is calculated to be used as a maximum adjusting route, a feasible adjusting route range is determined in the deflectable range based on the minimum adjusting route and the maximum adjusting route, and the feasible adjusting route range is displayed in a three-dimensional dynamic image.
In the embodiment of the invention, the selected adjusting route in the range of the feasible adjusting routes of the three-dimensional dynamic image is brought into a new flight plan in response to an operation instruction; or taking the route with the shortest path in the feasible adjusted route range as the adjusted route to be included in the new flight plan.
In the specific implementation, each sub-route or the combination of a plurality of sub-routes corresponds to a plurality of deflectable ranges, the deflectable ranges are areas in which the aircraft can effectively fly, a corresponding path is selected, the distance between the path and the corresponding conflict sub-route is greater than a standard safe distance, when the path is selected, two minimum adjustment routes can be selected on the basis that the two conflict routes are deflected, one route can be kept unchanged, the other route is deflected to select the minimum adjustment route, and a path without conflict with routes other than the conflict sub-route can be selected, specifically, the conflict on the position and the time determined in the invention is included.
In particular implementations, the minimum adjusted route generally refers to a path such that the distance between conflicting sub-routes is just greater than or equal to a standard safe distance, the maximum adjusted route does not correspond to the maximum route deviation path and refers to the adjusted route having the longest path, but does not refer to the longest path in order to distinguish from the minimum adjusted route, and there may be multiple routes.
In a particular implementation, the feasible adjusted course range is generally the area between the minimum adjusted course and the maximum adjusted course, and given that in some cases other sub-courses may cross or pass through the deviatable range, in this case the feasible adjusted course range may be the area between the minimum course deviation path and the minimum adjusted course, and the area between the maximum adjusted course and the maximum course deviation path, and further, if there are multiple other courses that pass through the deviatable range, then multiple maximum adjusted courses may be calculated, and a range in which the aircraft may fly efficiently without course conflicts is determined. In practical applications, for the deviating areas of certain sub-routes or combinations, there is actually no minimum or maximum adjustment route from which to choose, in which case the deviating range of the sub-route or combination is ignored.
In specific implementation, the feasible lane adjustment range obtained based on the environment, the aircraft performance and the lane conflict can intuitively and effectively provide the adjustable area of the aircraft, so that the subsequent air plan can be effectively adjusted conveniently.
In particular implementations, the system may use the shortest route of the range of feasible adjusted routes as an adjusted route to replace the original sub-route or combination of sub-routes to resolve conflicts based on efficiency priority considerations, but in some cases may be selected by the user through an intervention interaction, particularly based on three-dimensional dynamic imagery, for more stable and safe air planning, or other special purposes and requirements, where the user may be quite intuitive to view the area of the aircraft where the route adjustment may be made and select a route therein as the adjusted route to replace the original route.
In specific implementation, after simulation deduction is finished, the original air plan airspace, the air route conflict condition, the resolved conflict condition and the unresolved conflict condition can be displayed, a certain unresolved conflict is clicked, the time period, the position and the process of the conflict occurrence in the three-dimensional scene can be switched to dynamic display, the whole process of the original air plan can be displayed in a three-dimensional scene mode through simulation deduction process duplication, and scene view angle switching and space position continuous dragging display are supported.
