[0039] At block 204, it is determined whether there is currently an ND display. If it is determined at block 402 that there is currently no ND display, then at block 206, ND is displayed from none to one, and then the process proceeds to block 208. On the other hand, if it is determined at block 204 that there is currently an ND display, the process proceeds directly to block 208.

[0040] At block 208, determine if the ND is in MAP format. If it is determined at block 208 that the ND is not in MAP format, then switch the ND to MAP format at block 210 and then go to block 212. On the other hand, if it is determined at block 208 that the ND is already in MAP format, then go directly to block 212.

[0041] At block 212, the vertical section is automatically displayed. According to an exemplary embodiment, automatically displaying the vertical section may include causing the vertical section to be automatically displayed in a specific display area of ​​the display system.

[0045] exist Figure 2 The display process 200 of the vertical section display provides an embodiment of the vertical section display based on the ND display, and in particular based on the MAP format of the ND display. The vertical section display is usually an important component of the navigation page in the display system, which can provide information such as routes, restrictions, terrain, etc. in the vertical direction corresponding to a certain horizontal range of the current position of the aircraft. Displaying the vertical section together with the MAP format of the ND can generally form an effective complement to the horizontal navigation page (MAP) of the traditional bird's-eye view, provide the flight crew with more comprehensive flight status information, and improve the crew's situational awareness.

[0046] Despite Figure 2 The display process 200 of the vertical profile display provides an embodiment of the vertical profile display based on the ND display, and in particular based on the MAP format of the ND display, but a person skilled in the art should understand that the field is not limited thereto, but should cover embodiments in which the vertical profile display is based on other displays and embodiments in which the vertical profile display is not based on any other display. For example, according to some alternative embodiments, automatically displaying the vertical profile may include automatically displaying the vertical profile in a specific display area of ​​the display system. According to some exemplary embodiments, automatically displaying the vertical profile in a specific display area of ​​the display system may include one or more of the following or any combination thereof: displaying the vertical profile in an unoccupied specific display area of ​​the display system; displaying the vertical profile at least partially over a specific display area of ​​the display system that is occupied by other display content; and shrinking or rearranging other display content in an occupied specific display area of ​​the display system to display the vertical profile in the vacated area, etc.

[0047] Figure 3A schematic diagram of a display 300 showing a vertical profile along with a MAP format of a navigation display (ND) according to an aspect of the present disclosure is shown. Figure 3 The display 300 may be, for example, composed of the above combination Figure 1 The vertical section display system 100 described above adopts, for example, the above combination Figure 2 The display process 200 for vertical section display described is displayed. However, as known to those skilled in the art, in other embodiments of the present application, the vertical section does not have to rely on the MAP format of the navigation display (ND), or even on the navigation display (ND), but should cover embodiments in which the vertical section display is based on other displays as well as embodiments in which the vertical section display is not based on any other display. For example, according to some alternative embodiments, automatically displaying the vertical section may include automatically displaying the vertical section in a specific display area of ​​the display system. According to some exemplary embodiments, automatically displaying the vertical section in a specific display area of ​​the display system may include one or more of the following or any combination thereof: displaying the vertical section in an unoccupied specific display area of ​​the display system; causing the vertical section display to at least partially cover a specific display area of ​​the display system that is occupied by other display content; and causing other display content in an occupied specific display area of ​​the display system to shrink or rearrange to display the vertical section in the vacated area, etc.

[0048] like Figure 3 As shown in FIG. 3 , according to an exemplary embodiment, the layout of display 300 includes a MAP format of a navigation display (ND) displayed on top, wherein a bottom triangle indicates the direction of the aircraft nose, and a straight line with an upward apex angle of the triangle corresponds to a vertical profile. According to an exemplary embodiment, Figure 3 In the vertical section, the right direction represents the direction in which the aircraft is moving.

[0049] According to an exemplary embodiment, the layout of display 300 also includes a vertical section displayed below. The vertical section may correspond to, for example, a straight line with the top angle of the triangle indicating the direction of the aircraft nose in the navigation display (ND) above pointing upward. That is, the vertical section corresponds to the section represented by the straight line. Although it is not necessary to display the vertical section together with the MAP format of the ND according to the present application, doing so can effectively complement the horizontal navigation page (MAP) of the traditional bird's-eye view of the vertical section, provide the flight crew with more comprehensive flight status information, and improve the crew's situational awareness.

[0050] As known to those skilled in the art, the present disclosure is not limited to Figure 3 The layout of display 300 shown in FIG. 3 may include other layouts. For example, the vertical section may be displayed above the MAP, or the vertical section may be displayed as a picture-in-picture in the MAP, etc. According to an exemplary embodiment, Figure 3The display 300 shown in FIG. 3 may be displayed on the same physical display, or the MAP and the vertical section may be displayed on different but adjacent physical displays, and so on.

[0051] According to an exemplary embodiment, the distance of the display 300 that displays the vertical section along with the MAP format of the navigation display (ND) is preferably consistent with the scale of the MAP to facilitate a more intuitive understanding for the crew.

[0052] Figure 4 A schematic diagram of a display 400 showing a vertical profile along with a MAP format of a navigation display (ND) according to an aspect of the present disclosure is shown. Figure 4 The display 400 may be, for example, composed of the above combination Figure 1 The vertical section display system 100 described above adopts, for example, the above combination Figure 2 The display process 200 for vertical section display described is displayed. However, as known to those skilled in the art, in other embodiments of the present application, the vertical section does not have to rely on the MAP format of the navigation display (ND), or even on the navigation display (ND), but should cover embodiments in which the vertical section display is based on other displays as well as embodiments in which the vertical section display is not based on any other display. For example, according to some alternative embodiments, automatically displaying the vertical section may include automatically displaying the vertical section in a specific display area of ​​the display system. According to some exemplary embodiments, automatically displaying the vertical section in a specific display area of ​​the display system may include one or more of the following or any combination thereof: displaying the vertical section in an unoccupied specific display area of ​​the display system; causing the vertical section display to at least partially cover a specific display area of ​​the display system that is occupied by other display content; and causing other display content in an occupied specific display area of ​​the display system to shrink or rearrange to display the vertical section in the vacated area, etc.

[0053] like Figure 4 As shown in FIG. 4 , according to an exemplary embodiment, the layout of display 400 includes a MAP format of a navigation display (ND) displayed on the left, wherein a bottom triangle indicates the direction of the aircraft nose, and a straight line with an upward apex angle of the triangle corresponds to a vertical profile. According to an exemplary embodiment, Figure 3 In the vertical section, the upward direction represents the direction of the aircraft's movement, which is consistent with the direction in the MAP format.

[0054] According to an exemplary embodiment, the layout of display 400 also includes a vertical section displayed on the right. The vertical section may correspond to, for example, a straight line with the top angle of the triangle indicating the direction of the aircraft nose in the navigation display (ND) above pointing upward. That is, the vertical section corresponds to the section represented by the straight line. Although it is not necessary to display the vertical section with the MAP format of the ND according to the present application, doing so can effectively complement the horizontal navigation page (MAP) of the traditional bird's-eye view of the vertical section, provide the flight crew with more comprehensive flight status information, and improve the crew's situational awareness.

[0055] As known to those skilled in the art, the present disclosure is not limited to Figure 4 The layout of display 400 shown in FIG. 4 may include other layouts. For example, the vertical section may be displayed on the left side of the MAP, or the vertical section may be displayed as a picture-in-picture in the MAP, etc. According to an exemplary embodiment, Figure 4 The display 400 shown in FIG. 4 can be displayed on the same physical display, or the MAP and the vertical section can be displayed on different but adjacent physical displays, and so on.

[0056] According to an exemplary embodiment, the distance of the display 400 that displays the vertical section along with the MAP format of the navigation display (ND) is preferably consistent with the scale of the MAP to facilitate a more intuitive understanding for the crew.

[0057] Figure 5 A schematic diagram of a preferred embodiment of an automatic vertical section display system 500 for operation scenarios according to an aspect of the present disclosure is shown. The automatic vertical section display system 500 may include a display management system. The display management system may receive input from an input part.

[0058] According to an exemplary embodiment, the input portion may include various systems, including but not limited to, for example, a weather radar system (WXR), a terrain awareness and warning system (TAWS), etc. These systems may provide alerts to the display management system. According to an exemplary embodiment, the alerts may be divided into two or more levels. For example, the alerts may be divided into a warning level and an alert level, etc.

[0059] The display management system may receive an alarm from an input portion. According to an exemplary embodiment, the display management system may perform different vertical profile displays for different alarm levels. According to some exemplary embodiments, based on different alarm levels, the display management system may determine whether to perform a vertical profile display and what type of vertical profile display to perform. For example, for an alert level alarm, the display management system may instruct a conventional vertical profile display. For another example, for a warning level alarm, the display management system may seize the display area with the lowest priority to perform a vertical profile display.

[0060] On the other hand, for warning level alerts, the display management system may provide alerts in addition to the conventional vertical profile display. For example, according to an exemplary embodiment, the alert may include flashing, sounding, text prompts, symbol prompts, etc., and / or may include, for example, changing one or more display features (e.g., color, brightness, thickness, font, shading, etc.) of the conventional vertical profile display.

[0061] According to an exemplary embodiment, the input part may further include one or more flight management systems (FMS). These flight management systems (FMS) may provide flight control information, such as information about the final approach point (FAF), airport elevation, etc., to the display management system.

[0062] According to an exemplary embodiment, the display management system may receive information about the final approach point (FAF), airport elevation, etc. from the input part. According to an exemplary embodiment, the display management system issues instructions to the display system (not shown) based on the various information received from the input part (including but not limited to various warning information and / or flight control information) according to the urgency of the crew's response required for abnormal scenarios and normal scenarios.

[0063] According to an exemplary embodiment, the display management system controls the display system to automatically open / overlay the vertical profile through instructions based on normal and abnormal operating conditions in combination with the cockpit display configuration. Specifically, according to an exemplary embodiment, when the display management system receives warning information in an abnormal scenario (e.g., from a weather radar system (WXR) and / or a terrain awareness and warning system (TAWS)), the display management system sends (e.g., to the display system) an abnormal scenario VD display instruction. On the other hand, when the display management system receives flight control information in a normal scenario (e.g., from each flight management system (FMS), etc.), the display management system sends (e.g., to the display system) a normal scenario VD display instruction.

[0064] Specifically, when the display management system sends an abnormal scene VD display instruction to the display system, the display system determines the number status of the current display windows to determine whether there is an available display area.

[0065] According to an exemplary embodiment, if the number of current display windows indicates that there is no available display area, the display system may reduce other display contents in the occupied specific display area of ​​the display system or rearrange the display area to free up area for VD display.

[0066] The display system then determines whether there is currently an ND display. If there is currently no ND display, the MAP is displayed in a designated window of the display system (e.g., designated windows on both sides of the display system), followed by a vertical profile of an appropriate distance. According to an exemplary embodiment, in the case where the current operating scenario is an abnormal operating scenario, the appropriate distance range is determined based on the corresponding abnormal operating scenario.

[0067] If there is currently an ND display, determine whether the current ND display is in MAP format. If so, automatically display MAP, and then display the vertical section of the appropriate distance. If not, switch the PLAN to MAP format, and then display the vertical section of the appropriate distance.

[0068] On the other hand, when the display management system sends a normal scene VD display instruction to the display system, since there is currently an ND display in the normal scene, it only needs to determine whether the current ND display is in MAP format. If so, MAP is automatically displayed, and then the vertical section of the appropriate distance is displayed. If not, PLAN is switched to MAP format, and then the vertical section of the appropriate distance is displayed.

[0069] Figure 6 A flowchart of a method 600 for displaying a vertical section of an operation scene according to an aspect of the present disclosure is shown.

[0070] According to an exemplary embodiment, Figure 6 The operation scenario-oriented vertical profile display method 600 may include receiving a vertical display (VD) display trigger in box 602. According to an exemplary embodiment, the VD display may be triggered under normal operating conditions, and / or triggered under abnormal normal operating conditions. According to an exemplary embodiment, for example, a normal operating scenario may include, but is not limited to, one or more normal operating scenarios such as the final approach phase, take-off from a plateau airport, landing at a plateau airport, etc. According to an exemplary embodiment, an abnormal normal operating scenario may include, but is not limited to, an alarm triggering scenario. For example, according to some exemplary embodiments, an abnormal normal operating scenario may include, but is not limited to, one or more abnormal normal operating scenarios such as a weather alarm triggering, a terrain alarm triggering, etc. As known to those skilled in the art, various normal and / or abnormal normal operating scenarios may be defined according to various regulations, practices, needs, preferences, etc.

[0071] According to an exemplary embodiment, receiving a VD display trigger in box 602 may include receiving a VD display trigger from various systems, including but not limited to, for example, a weather radar system (WXR), a terrain awareness and warning system (TAWS), etc., which may provide a VD display trigger including an alert; and also including but not limited to various flight management systems (FMS), which may provide a VD display trigger including flight control information.

[0072] According to an exemplary embodiment, Figure 6 The operation scenario-oriented vertical profile display method 600 may include determining the current operation scenario in box 604. For example, the operation scenario may include a normal operation scenario and an abnormal operation scenario. The current operation scenario may be determined according to the type of the VD display trigger received in box 602. For example, when the VD display trigger received in box 602 includes an alarm, it is determined that the current operation scenario is an abnormal operation scenario. For another example, when the VD display trigger received in box 602 includes flight control information (for example, information about the final approach point (FAF), airport elevation, etc.), it is determined that the current operation scenario is a normal operation scenario.

[0073] According to an exemplary embodiment, Figure 6 The vertical profile display method 600 for operation scenarios may include automatically displaying a VD within a suitable range circle based on the ND display in the MAP format at block 606. According to an exemplary embodiment, automatically displaying a VD within a suitable range circle based on the ND display in the MAP format may include automatically displaying a VD within a suitable range circle based on the ND display in the MAP format according to the current operation scenario. For example, if the current operation scenario is an abnormal operation scenario, it is determined whether there is an ND display. If not, the ND in the MAP format is displayed from scratch in the designated window.

[0074] According to an exemplary embodiment, automatically displaying a VD within a suitable range circle based on an ND display in a MAP format may include determining whether an existing ND display is in a MAP format, and switching the current ND display to a MAP format if the ND display is not in a MAP format.

[0075] According to an exemplary embodiment, automatically displaying the VD within the appropriate range circle based on the ND display in the MAP format may further include automatically displaying a vertical profile of the appropriate range in the case where the ND display in the MAP format is currently present.

[0076] Although the above embodiment of the present application describes the vertical profile display as being displayed in the case of an ND display in a MAP format, this is only a preferred embodiment of the present disclosure, and the solution of the present disclosure is not limited thereto. In fact, the vertical profile display for the operation scenario of the present application can be displayed independently of the ND display in a MAP format, or even independently of the ND display.

[0077] The above description is only an exemplary embodiment of the present invention. However, the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.

[0078] The various illustrative logical blocks, modules, and circuits described in conjunction with the present disclosure may be implemented or executed with a general purpose processor, a digital signal processor (DSP), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA) or other programmable logic device (PLD), discrete gate or transistor logic, discrete hardware components, or any combination thereof designed to perform the functions described herein. A general purpose processor may be a microprocessor, but in the alternative, the processor may be any commercially available processor, controller, microcontroller, or state machine. The processor may also be implemented as a combination of computing devices, for example, a combination of a DSP and a microprocessor, a plurality of microprocessors, one or more microprocessors in conjunction with a DSP core, or any other such configuration.

[0079] The steps of the method or algorithm described in conjunction with the present disclosure may be implemented directly in hardware, in a software module executed by a processor, or in a combination of the two. The software module may reside in any form of storage medium known in the art. Some examples of usable storage media include random access memory (RAM), read-only memory (ROM), flash memory, EPROM memory, EEPROM memory, registers, hard disks, removable disks, CD-ROMs, and the like. The software module may include a single instruction, or many instructions, and may be distributed over several different code segments, distributed between different programs, and distributed across multiple storage media. A storage medium may be coupled to a processor so that the processor can read and write information from / to the storage medium. Alternatively, a storage medium may be integrated into a processor.

[0080] The methods disclosed herein include one or more steps or actions for achieving the described methods. These method steps and / or actions may be interchangeable with each other without departing from the scope of the claims. In other words, unless a specific order of steps or actions is specified, the order and / or use of specific steps and / or actions may be changed without departing from the scope of the claims.

[0081] The processor can execute software stored on a machine-readable medium. The processor can be implemented with one or more general and / or special processors. Examples include microprocessors, microcontrollers, DSP processors, and other circuit systems that can execute software. Software should be broadly interpreted as meaning instructions, data, or any combination thereof, whether it is called software, firmware, middleware, microcode, hardware description language, or other. As an example, a machine-readable medium may include RAM (random access memory), flash memory, ROM (read-only memory), PROM (programmable read-only memory), EPROM (erasable programmable read-only memory), EEPROM (electrically erasable programmable read-only memory), registers, disks, optical disks, hard drives, or any other suitable storage media, or any combination thereof. The machine-readable medium may be implemented in a computer program product. The computer program product may include packaging materials.

[0082] In a hardware implementation, the machine-readable medium may be a part of a processing system that is separate from the processor. However, as will be readily appreciated by those skilled in the art, the machine-readable medium or any part thereof may be external to the processing system. As an example, the machine-readable medium may include a transmission line, a carrier modulated by data, and / or a computer product separate from the wireless node, all of which may be accessed by the processor via a bus interface. Alternatively or in addition, the machine-readable medium or any part thereof may be integrated into the processor, such as a cache and / or a general register file may be the case.

[0083] The processing system can be configured as a general processing system having one or more microprocessors providing processor functionality and external memory providing at least a portion of the machine-readable medium, all linked together with other supporting circuitry via an external bus architecture. Alternatively, the processing system can be implemented with an ASIC (Application Specific Integrated Circuit) with a processor, bus interface, user interface (in the case of an access terminal), supporting circuitry, and at least a portion of the machine-readable medium integrated in a single chip, or with one or more FPGAs (field programmable gate arrays), PLDs (programmable logic devices), controllers, state machines, gating logic, discrete hardware components, or any other suitable circuitry, or any combination of circuits capable of performing the various functionalities described throughout this disclosure. Those skilled in the art will recognize how to best implement the functionality described with respect to the processing system, depending on the specific application and the overall design constraints imposed on the overall system.

[0084] The machine-readable medium may include several software modules. These software modules include instructions that cause a processing system to perform various functions when executed by a device (such as a processor). These software modules may include a transmission module and a reception module. Each software module may reside in a single storage device or be distributed across multiple storage devices. As an example, when a triggering event occurs, a software module may be loaded into a RAM from a hard drive. During the execution of the software module, the processor may load some instructions into a cache to increase access speed. One or more cache lines may then be loaded into a general register file for execution by the processor. When the functionality of a software module is described below, it will be understood that such functionality is implemented by the processor when the processor executes instructions from the software module.

[0085] If implemented in software, each function can be stored on or transmitted by one or more instructions or codes on a computer-readable medium. Computer-readable media include both computer storage media and communication media, and these media include any media that facilitate the transfer of a computer program from one place to another. Storage media can be any available media that can be accessed by a computer. As an example and not limitation, such computer-readable media may include RAM, ROM, EEPROM, CD-ROM or other optical disk storage, disk storage or other magnetic storage devices, or any other media that can be used to carry or store the desired program code in the form of instructions or data structures and can be accessed by a computer. Any connection is also properly referred to as a computer-readable medium. For example, if the software is transmitted from a website, server, or other remote source using a coaxial cable, fiber optic cable, twisted pair, digital subscriber line (DSL), or wireless technology (such as infrared (IR), radio, and microwave), the coaxial cable, fiber optic cable, twisted pair, DSL, or wireless technology (such as infrared, radio, and microwave) is included in the definition of the medium. As used herein, disk and disc include compact disc (CD), laser disc, optical disc, digital versatile disc (DVD), floppy disk, and Disks, where disks often reproduce data magnetically, and discs reproduce data optically with lasers. Thus, in some aspects, computer-readable media may include non-transitory computer-readable media (e.g., tangible media). Additionally, for other aspects, computer-readable media may include transient computer-readable media (e.g., signals). Combinations of the above should also be included within the scope of computer-readable media.

[0086] Thus, some aspects may include a computer program product for performing the operations presented herein. For example, such a computer program product may include a computer-readable medium having stored (and / or encoded) thereon instructions that can be executed by one or more processors to perform the operations described herein. In some aspects, a computer program product may include packaging materials.

[0087] It will be understood that the claims are not limited to the precise configuration and components illustrated above. Various changes, substitutions and variations may be made in the arrangement, operation and details of the methods and apparatus described above without departing from the scope of the claims.
