[0113] Reference Figure 2 , Figure 2 FIG. 1 is a flow chart of a first exemplary embodiment of a flight display method. The flight display method comprises:

[0114] Step S10, obtaining the position and three-dimensional map information of the aircraft;

[0115] Specifically, the flight management system obtains the position of the aircraft, including the altitude and longitude and latitude of the aircraft, where the altitude of the aircraft is obtained through existing altitude measurement technology; the longitude and latitude of the current aircraft are determined through GPS satellite positioning or other means; the three-dimensional map information is real-life information such as the height and width of buildings obtained through satellites or other technical means.

[0116] Step S20, displaying a route and navigation node visual map on the screen of the aircraft according to the position of the aircraft, the three-dimensional map information, the preset route information and the preset route nodes.

[0117] Specifically, the preset route information includes the latitude and longitude, route and direction of the starting position and the target position; the flight management system obtains the result of step S110 and the preset information, such as the preset route nodes, the number and interval distance of the preset route nodes, to obtain a three-dimensional route layer; the three-dimensional map information and the position of the aircraft are merged to obtain a three-dimensional map layer; according to the position of the aircraft, the preset route nodes and the route information, a route node layer is obtained; based on the three-dimensional route map layer, the three-dimensional route layer and the route node layer, the route and navigation node visual map is displayed on the screen of the aircraft.

[0118] This embodiment uses the above scheme, specifically by obtaining the position and three-dimensional map information of the aircraft; according to the position of the aircraft, the three-dimensional map information, the preset route information and the preset route node, the route and navigation node visual map is displayed on the screen of the aircraft. Based on this scheme, by displaying the route and navigation node visual map on the screen of the aircraft and dynamically adjusting it according to the position of the aircraft, it is possible to dynamically and effectively display the relevant information when the aircraft passes through the route node, which provides convenience for people who want to understand the flight status of the aircraft and provides a way to display the relevant information of the current route node.

[0119] Further, refer to Figure 3 , Figure 3 The flowchart of the second exemplary embodiment of the flight display method is shown in FIG. 1 , wherein the step of displaying the route and navigation node view on the screen of the aircraft according to the position of the aircraft, the three-dimensional map information, the preset route information and the preset route nodes comprises:

[0120] Step A10, fusing the three-dimensional map information and the position of the aircraft to obtain a three-dimensional map layer;

[0121] Specifically, the flight management system obtains the position of the aircraft, and then fuses the information of the two to obtain the position in the three-dimensional map, thereby obtaining a three-dimensional map layer.

[0122] Step A20, obtaining a three-dimensional route layer according to the preset route information and the position of the aircraft;

[0123] Specifically, the flight management system can simulate the three-dimensional route layer logo and the destination position logo according to the preset route information and the position of the aircraft, adjust the three-dimensional route layer logo, and gradually reduce the node display frame of the route node from near to far along the flight direction of the aircraft to obtain the three-dimensional route layer.

[0124] Step A30, obtaining a route node layer according to the position of the aircraft, the preset route node and the route information;

[0125] Specifically, the interval between each route node is controlled according to the nodes of the preset route and the number of nodes of the route, and a display graph of the route node is simulated. The route node is displayed from near to far and from large to small in a certain proportion according to the distance between the route node and the current aircraft to obtain a route node layer.

[0126] Step A40, based on the three-dimensional route map layer, the three-dimensional route layer, and the route node layer, display the route and navigation node visual image on the screen of the aircraft.

[0127] Specifically, the flight management system integrates the three-dimensional route map layer, the three-dimensional route layer, and the route node layer and displays them on the screen of the aircraft as a route and navigation node visual map.

[0128] This embodiment adopts the above scheme, specifically by fusing the three-dimensional map information and the position of the aircraft to obtain a three-dimensional map layer; according to the preset route information and the position of the aircraft, a three-dimensional route layer is obtained; according to the position of the aircraft, the preset route node and the route information, a route node layer is obtained; based on the three-dimensional route map layer, the three-dimensional route layer and the route node layer, a route and navigation node visual map is displayed on the screen of the aircraft. Based on this scheme, according to the position of the aircraft, the three-dimensional map information, the preset route information and the preset route node, a route and navigation node visual map is displayed on the screen of the aircraft, thereby achieving the effect of being able to dynamically and effectively display the flight vision of the aircraft.

[0129] Further, refer to Figure 4 , Figure 4 The flowchart of the third exemplary embodiment of the flight display method is as follows. The step of obtaining the route node layer according to the position of the aircraft, the preset route node and the route information includes:

[0130] Step A100, simulating a three-dimensional node display frame of the route node layer according to the preset route nodes;

[0131] Specifically, the simulated shape of the route node is a variety of three-dimensional display graphics styles, which are not limited. Here, a three-dimensional node display frame is used as one of the embodiments for explanation.

[0132] Step A200, adjusting the node display frame according to the position of the aircraft and the route information to obtain a route node layer.

[0133] Specifically, the target waypoint and the flight direction are determined from the route information, and the node display frame of the route node is gradually reduced from near to far along the flight direction of the aircraft to obtain a route node layer.

[0134] This embodiment uses the above scheme to simulate the three-dimensional node display frame of the route node layer according to the preset route nodes; and adjusts the node display frame according to the position of the aircraft and the route information to obtain the route node layer. This achieves the effect of three-dimensionally displaying the position of the route node on the route, and also provides a display method for displaying route node related information, effectively showing the effect of the arrangement of the route node position on the route.

[0135] Further, refer to Figure 5 , Figure 5 The flowchart of the fourth exemplary embodiment of the flight display method further includes: after the step of displaying the route and navigation node view on the screen of the aircraft based on the three-dimensional route map layer, the three-dimensional route layer, and the route node layer, the following steps are included:

[0136] Step S301, adjusting the display position of the route node layer on the display screen of the aircraft according to the route change of the aircraft.

[0137] Specifically, when the aircraft is actually flying, it will deviate left or right or change altitude relative to the preset route information. At this time, the three-dimensional route layer generated by the flight management system will change. In order to ensure the display effect, it is necessary to adjust the position of the node display frame of the route node layer to ensure that the logo of the three-dimensional route layer is in the appropriate position of the node display frame to achieve the overall display effect.

[0138] This embodiment uses the above solution to adjust the display position of the route node layer on the display screen of the aircraft according to the route change of the aircraft. Based on this solution, the flight status of the aircraft when passing through the route node is dynamically and effectively displayed, which increases the fun of the flight and ensures that the node display frame is always displayed at the appropriate position of the route.

[0139] Further, refer to Figure 6 , Figure 6 The flowchart of the fifth exemplary embodiment of the flight display method further includes: after the step of displaying the route and navigation node view on the screen of the aircraft based on the three-dimensional route map layer, the three-dimensional route layer, and the route node layer, the following steps are included:

[0140] Step S302, obtaining a forward route node that is closest to the aircraft as a first node;

[0141] Specifically, the flight management system uses the longitude and latitude of the preset route node, the longitude and latitude of the aircraft position and the preset route information to select the route node with the smallest distance in front of the aircraft along the flight direction of the aircraft as the first route node.

[0142] Step S303, when the distance between the aircraft and the first node reaches a preset first distance, adjusting the display angle of the route and navigation node view on the display screen of the aircraft;

[0143] Specifically, the distance between the preset route and the aircraft and the first node is determined and compared with the preset first distance. When the first distance is reached, the flight management system adjusts the display position of the route node layer on the display screen of the aircraft to a front view position.

[0144] Step S304, when the position of the aircraft reaches the first node, the position information of the first node is displayed on the node display box of the first node, and / or a voice broadcast is performed so that relevant personnel can understand the current flight situation.

[0145] Specifically, when an aircraft passes through a route node during flight, the flight management system obtains the corresponding location name, longitude and latitude information, altitude information, etc. by receiving satellite positioning or other means, and then displays it to the flight crew or other relevant personnel through the screen on the aircraft, or informs them through voice broadcast.

[0146] This embodiment adopts the above scheme, specifically by obtaining the route node in front that is closest to the aircraft as the first node; when the distance between the aircraft and the first node reaches the preset first distance, the display angle of the route and navigation node view map on the display screen of the aircraft is adjusted; when the position of the aircraft reaches the first node, the position information of the first node is displayed on the node display box of the first node, and / or a voice broadcast is performed to allow relevant personnel to understand the current flight situation. Based on this scheme, after the aircraft reaches a certain distance from the route node in front, the route and navigation node view map is adjusted to a front view position, and when passing by, the corresponding place name and longitude and latitude information, altitude information, etc. are displayed on the node display box in the route and navigation node view map, and the flight crew can also be informed by voice broadcast, so as to achieve dynamic and effective display of accurate information when the aircraft flies through the route node, which brings convenience to relevant personnel.

[0147] Further, refer to Figure 7 , Figure 7 This is a flow chart of a sixth exemplary embodiment of a flight display method, wherein when the position of the aircraft reaches the first node, the position information of the first node is displayed on the node display frame of the first node, and / or a voice broadcast is performed to allow relevant personnel to understand the current flight situation, and the step also includes:

[0148] Step S305: if the aircraft flies away from the first node to a preset second distance, the node display frame of the first node is not displayed;

[0149] Specifically, after the aircraft passes the first node, it flies away to a preset distance. In order to ensure that the view is always forward like real driving, and only the view display effect of the route node ahead can be seen, the node display frame of the first node passed is no longer displayed.

[0150] Step S306: If the display time of the node display frame of the first node reaches a preset time, the node display frame of the first node is not displayed.

[0151] Specifically, when the position of the navigation route visual map of the aircraft is adjusted, the size, position and angle of the node display frame are maintained for display until a preset time is reached, and the node display frame of the first node is no longer displayed.

[0152] This embodiment adopts the above scheme, specifically, if the aircraft flies away from the first node to a preset second distance, the node display frame of the first node is not displayed; or if the display time of the node display frame of the first node reaches a preset time, the node display frame of the first node is not displayed. This scheme removes the node display frame that has flown over a preset distance or preset time according to the change of the route of the aircraft, avoiding interference and confusion in the display of the current flight status, achieving the effect of dynamically and effectively displaying the navigation route visual map, and improving the flight experience of the flight crew.

[0153] Further, refer to Figure 8 , Figure 8 2 is a flow chart of a seventh exemplary embodiment of a flight display method, wherein the steps of the flight display method further include:

[0154] Step S307, controlling the route and navigation node view to switch to the first perspective or the third perspective, and displaying them on the screen of the aircraft;

[0155] Specifically, during the first display, it is displayed according to a pre-set perspective. During the display process, the display mode can be controlled by relevant personnel to switch the display perspective to the first perspective or the third perspective; the first perspective refers to the three-dimensional route layer visual information and the three-dimensional node display frame visual information displayed from the pilot's perspective; the third perspective refers to the aircraft, three-dimensional route layer visual information, three-dimensional map layer visual information, three-dimensional node display frame visual information, etc. displayed from the perspective outside the aircraft, so that people can view the overall flight vision of the aircraft.
