Description

Non-operational item warning method and system for airplane

Technical Field

The invention relates to the field of avionics human-computer interface design, in particular to a non-working item warning method and system for an airplane.

Background

The design of the integrated warning system is always the research focus of various civil aircraft manufacturers. However, the highly complex internal logic and the complex data cross-linking relationship with the aircraft systems greatly increase the difficulty of design and verification. While the display and the alarm system are deeply integrated, in order to facilitate the handling of the pilot, the intelligent design features are necessarily required to be introduced.

In the design of the current mainstream model for the comprehensive alarm system, the non-operation item list is mainly divided according to the flight stage or different alarm messages. However, the above-described division and display method of the list of the non-working items has disadvantages.

In particular, for a list of non-operational items divided according to flight phases, the classification definition is not clear. The non-operational items are displayed in two categories, the "all flight phase" and the "approach landing phase" as in the current art. In actual use, there may be ambiguity or uncertainty in classification, such as non-operational terms in some approach landing phases, which may also affect the flight performance or flight quality in other flight phases. The two categories cannot be logically mutually exclusive, thereby causing to some extent pilot misunderstanding or confusion.

And for the non-working item list divided according to different alarm messages, repeated display of non-working items can occur. When non-working items associated with the same alarm message are listed under the same title, duplication may occur in different lists if different alarm messages are associated with the same non-working items. When the number of alarm messages is large, the classification method may increase the workload of the pilot for acquiring the information of the non-working items.

In response to the deficiencies of existing inactive item display designs, it is desirable to provide an improved inactive item alert method and system for an aircraft.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings in conjunction with specific embodiments. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the described exemplary embodiments. It will be apparent, however, to one skilled in the art, that the described embodiments may be practiced without some or all of these specific details. In other exemplary embodiments, well-known structures have not been described in detail to avoid unnecessarily obscuring the concepts of the present disclosure. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. Meanwhile, the various aspects described in the embodiments may be arbitrarily combined without conflict.

In the existing non-working item display design, the classification definition of a non-working item list divided according to the flight phase is not clear, and classification ambiguity or uncertainty may exist in the actual use process, so that misunderstanding of a pilot is caused. And the non-working item list divided according to different alarm messages can be repeatedly displayed, so that the workload of acquiring the non-working item information by the pilot is increased.

The invention provides an improved out-of-operation item warning method and system for an airplane, which avoid the defects of the prior art, reduce the workload of a pilot and improve the flight safety.

FIG. 1 illustrates a flow chart of a dead item alert method 100 for an aircraft of the present invention.

The method 100 starts in step 105. At step 105, one or more alert messages triggered by an aircraft fault are received.

When the airplane is detected to be in an abnormal system state or an operating state, the airplane alarm system can send out an alarm. For example, an aircraft alert system may generate and provide alert messages to the crew.

At step 110, a list of non-operational items is generated based on the one or more alert messages, wherein non-operational items in the list of non-operational items indicate aircraft modules that are not operating properly.

Note that the abnormal operation here includes the abnormal operation caused by the failure of itself or the failure of another module. In addition, the airplane module which cannot normally work may refer to that the function module is not available (for example, the envelope protection function does not work, the autopilot does not work, etc.), or may refer to that a certain display function is not available (for example, all maps are not available, FMC performance information is not available, a heading cursor on a navigation page does not work, etc.), or hardware such as a control plane, a multifunctional spoiler does not work.

In some embodiments of the invention, different alert messages may be associated with the same non-operational item. For example, if different alert messages are triggered by a failure of the same aircraft module, the same non-operational item may be associated. Thus, there may be duplicate non-working items in the generated list of non-working items.

In step 115, the inactive items repeated in the list of inactive items are merged.

For the condition that the same non-working item is caused by a plurality of alarm messages, the repeated non-working items in the non-working item list can be integrated in real time, and the repeated non-working items are avoided.

Next, in step 120, a corresponding sorting rule is selected based on the aircraft operating state to sort the non-working items in the non-working item list, where at least one of the non-working items has a different relative priority in different aircraft operating states.

In embodiments of the present invention, the aircraft operating conditions include the system state, flight phase, performance requirements, etc. of the aircraft.

Different aircraft operating conditions may affect the relative priority of non-operational items. In particular, the system state of the aircraft (the operational or fault state of an existing system) may affect the ordering of the inoperative items. Different flight phases place different emphasis on certain functional modules, thereby also affecting the ordering of non-operational items. Furthermore, certain operating procedures selected by the pilot (e.g., different approach landing procedures, different takeoff thrust, etc. settings) may have particular performance requirements for the corresponding functional module, thereby also causing changes in the sequencing.

In some embodiments, the non-operational items associated with low hydraulic system pressure for normal retraction of the landing gear have a relatively high priority if the current system state indicates that the landing gear emergency release system is not operating properly. On the contrary, if the current system state indicates that the emergency landing gear system works normally, the non-working item related to the low pressure of the hydraulic system for the normal retraction of the landing gear has lower priority.

In some embodiments, if the current flight phase is a landing phase, the brake fault has a higher degree of impact on aircraft operation. In this case, the non-operational item related to the brake failure has a relatively high priority. Conversely, if the current flight phase is not the landing phase, the brake fault has a relatively low degree of impact on aircraft operation. In this case, the non-operational item related to the brake failure has a relatively low priority

In some embodiments, the pilot selecting different operating programs may have particular performance requirements for the corresponding functional modules. For example, a pilot selecting an instrument landing procedure may have higher performance requirements on the modules associated with the instrument landing procedure. If a module associated with the instrument landing system is not working properly and the pilot selects the instrument landing procedure, its non-working items have a relatively high priority. Conversely, if the pilot selects a VOR approach or other non-instrumented landing procedure, the non-operational item has a lower priority.

In some embodiments of the invention, a variety of sequencing rules may be defined for different aircraft operating conditions. For example, if the current flight phase is a landing phase, the sequencing rule may assign a relatively higher priority to non-operational items related to brake failure. Conversely, if the current flight phase is not a landing phase, the sequencing rule may assign a relatively lower priority to non-operational items related to brake failure.

Finally, at step 125, the sorted list of inactive items is displayed.

In the preferred embodiment, the ordered list of non-working items can be displayed in a window in the main view field range of the airplane pilot, so that the crew can conveniently look up in time, and the condition perception capability of the crew on the flight system is improved.

Preferably, the respective non-working items are displayed in a list form, and the highest-ranked non-working item is displayed uppermost in the list. In this way, the crew can be made more clear of system failure.

In some embodiments of the invention, the display area in the window may be configured to be interactive so that a particular inactive item may be selected (e.g., by cursor or touch). When an inoperative item is selected, an alert message associated with the inoperative item may be displayed in a window.

In an embodiment of the present invention, when an alert message or an aircraft operation state changes, the list of inactive items may be updated and the updated list of inactive items may be displayed. Details regarding updating the list of inactive items are further described in FIG. 2.

The method 100 avoids the occurrence of repeated non-operational items in the list of non-operational items displayed to the crew by merging the repeated non-operational items, thereby reducing the workload of the crew. Meanwhile, the non-working items are sequenced, so that the condition perception capability of the unit on the aircraft system is further improved, and the flight safety is improved.

FIG. 2 illustrates an exemplary flow chart of a method 200 of updating a list of non-working items of the present invention.

And when the list of the non-working items is displayed in the window, if the alarm message or the aircraft running state changes, updating the list of the non-working items and displaying the updated list of the non-working items.

Specifically, in step 205, when a new alert message is received, a new non-working item associated with the new alert message is added to the non-working item list.

For example, if a new aircraft module fails, the aircraft alert system may generate a new alert message. At this time, a new non-working item associated with the new alert message may be generated. When the new non-working item is added to the non-working item list, the priority of the new non-working item can be determined and added to the proper position in the non-working item list according to the priority, so that the new non-working item list does not need to be reordered. Alternatively, the new non-working item may be added anywhere in the list of non-working items and the new list of non-working items may be reordered.

In some cases, the non-working items resulting from the new alert message may already be present in the list. At this point, the newly added non-working item is duplicated with the original non-working items in the list. In this case, the new list of non-operational items may be merged and sorted by the sorting unit, so that the newly added non-operational item is merged with the duplicate non-operational item in the original list. In other words, in some cases, the updated list of non-working items may be the same as the original list of non-working items.

At step 210, when all alert messages associated with an inoperative item in the list of inoperative items have been dismissed, the inoperative item is deleted from the list of inoperative items.

When all alarm messages associated with a certain non-working item have been released, the corresponding function module can be considered to have been cleared of faults and to be able to work normally. At this time, the non-working item may be deleted from the list of non-working items.

As an example, illustrated in connection with fig. 4 below, the non-working item "Autopilot inop" in fig. 4 is associated with two alert messages ("NAV INERTIAL SYS" and "FD FAULT"). Only if both alarm messages have been dismissed will the inoperative item "Autopilot inop" be deleted from the list. If only one of the alarm messages is dismissed, the inoperative item "automatic inop" remains in the list.

In step 215, when a new warning message is received or the aircraft operation state changes, the non-working items in the non-working item list are merged and sorted again.

For example, when the current flight phase of the aircraft changes, the priorities of some non-working items change, and the non-working items can be merged and sorted again according to the latest priorities.

Finally, at step 220, the updated list of inactive items is displayed. For example, the updated list of inactive items may be displayed in a window within the primary field of view.

It should be noted that the order of the above steps is exemplary. In various embodiments of the present invention, the steps described above may be performed in a different order or in parallel.

The method 200 enables the flight crew to know the latest aircraft fault condition in time by updating the list of non-operational items in real time, thereby further improving flight safety.

FIG. 3 illustrates an exemplary process 300 for non-operational item alerting for an aircraft of the present invention.

As shown, first, the aircraft alert system provides an alert message indication to the crew based on the current abnormal system status or operational status of the aircraft. For example, the aircraft alert system may generate one or more alert messages, such as alert message 1, alert message 2, and alert message 3 in the figure. It should be noted that the three alert messages shown in the figures are merely exemplary. In different implementations, more or less than three alert messages may be generated.

The generated alert messages may then be provided collectively to an alert processor for processing. The alert processor may form a list of non-operational items in conjunction with real-time pilot operation in the procedure.

Meanwhile, the alarm processor receives the parameters of the running state of the airplane, namely the system state, the flight phase, the performance requirement and the like. And the alarm processor selects a corresponding sorting rule based on the aircraft running state through comprehensive analysis, wherein the sorting rule assigns a specific priority to each non-working item. And the alarm processor sorts the non-working items in the non-working item list by using the selected sorting rule, generates a sorted non-working item list and displays the sorted non-working item list to the unit for reference.

In a preferred implementation, the inactive items are displayed in the form of a list in a separate page or window within the main field of view. In addition, manual hide and recall functionality may be provided, as well as automatic pop-up functionality under particular scenarios or conditions (e.g., when an aircraft enters a landing stage).

If the display area is configured as an interactive window or page, the corresponding non-working item can be clicked to look up the alarm message associated with the non-working item.

As shown, if an alert message or an aircraft operating state changes, the alert processor will receive real-time information, update the list of inactive items and display the updated list of inactive items. Details regarding updating the list of inactive items are described above in FIG. 2 and are not described in detail herein.

It should be noted that the process 300 shown in fig. 3 is merely exemplary. In different implementations, the worker in the art may implement the non-operational item alert in different ways. For example, in the implementation of fig. 3, when an alert message or an aircraft operating state changes, the original list of non-working items is updated (e.g., new non-working items are added to the original list, non-working items are deleted from the original list). In the replacement implementation, when the alarm message or the aircraft operation state changes, a new non-working item list can be generated according to the latest alarm message and the aircraft operation state and the original non-working item list is covered, instead of updating the original non-working item list.

FIG. 4 shows an interaction diagram 400 of the list of inactive items of the present invention.

In the implementation of displaying the list of the non-working items in the interactive window or page, the non-working items can be interacted through other hardware or software interaction modes such as cursor controller or touch control.

As shown in FIG. 4, an exemplary list of non-working items is listed on the left side of the page, including three non-working items: autopilot inop (Autopilot-on-the-fly), LNAV inop (lateral navigation-on-the-fly), VNAV inop (vertical navigation-on-the-fly).

When the non-working item in the non-working item list is selected, the warning message associated with the non-working item can be displayed in a page for the unit to refer.

As shown in fig. 4, when the "Autopilot inop" non-working item is selected, the associated alert messages "NAV INERTIAL SYS" and "FD FAULT" may be displayed in the blank area to the right of the non-working item.

It should be noted that the layout of the interaction diagram 400 of the list of inactive items shown in FIG. 4 is merely exemplary. In different implementations, different layouts may be used by those skilled in the art. For example, the non-workitems may be displayed centrally, on the right side of the page, and so on.

FIG. 5 illustrates a block diagram of a system 500 for non-operational item alerting of an aircraft of the present invention.

Referring to fig. 5, system 500 may include a list generation unit 502, a sorting unit 504, a display unit 506, and an update unit 508. Each of these units may be connected to or communicate with each other, directly or indirectly, over one or more buses 510.

In embodiments of the present invention, the list generation unit 502 may be configured to: receiving one or more alert messages; generating a list of non-working items based on the one or more alert messages, wherein non-working items in the list of non-working items indicate airplane modules that cannot work properly.

The update unit 508 may be configured to: and when the alarm message or the airplane operation state changes, updating the non-working item list and displaying the updated non-working item list.

In some embodiments of the invention, the update unit 508 may be further configured to: when a new alarm message is received, adding a new non-working item associated with the new alarm message to a non-working item list; deleting an inoperative item from the list of inoperative items when all alert messages associated with the inoperative item in the list of inoperative items have been dismissed; and when a new alarm message is received or the operation state of the airplane is changed, merging and sequencing the non-working items in the non-working item list again.

While specific elements of system 500 are shown in FIG. 5, it should be understood that these elements are exemplary only and not limiting. In different implementations, one or more of the units may be combined, divided, removed, or additional units may be added. For example, in some implementations, ordering unit 504 may be split into a merge subunit for merging duplicate non-working items and an ordering subunit for ordering non-working items. In some implementations, the display unit 506 and the update unit 508 may be combined into a single unit.
