Abstract

A system and method to assist a non-pilot in taking corrective action includes monitoring, in a health monitoring system, a state of health of an enabled aircraft autoland system to determine if a subsystem or component of the autoland system is in a fault condition that will inhibit operation of the autoland system. When the subsystem or component of the enabled autoland system is inoperable, The health monitoring system determines if the fault condition can be corrected by the non-pilot, by comparing the fault condition to a set of fault conditions in a fault condition database. When the fault condition can be corrected by the non-pilot, a display device is commanded, via the health monitoring system, to render a three-dimensional (3D) cockpit view of instructions for correcting the fault.

Description

    CROSS-REFERENCE TO RELATED APPLICATION
  • This application claims priority to India Provisional Patent Application No. 202211032222, filed June 6, 2022 , the entire content of which is incorporated by reference herein.
  • TECHNICAL FIELD
  • The present invention generally relates to a system for assisting a non-pilot in taking corrective action, and more particularly relates to a system for assisting a non-pilot in taking corrective action when an aircraft autoland system is enabled.
  • BACKGROUND
  • Many aircraft include an autoland system. As is generally known, an autoland system can take complete control of, and land, the aircraft in an emergency, such as in the unlikely event the pilot is unable to fly. The autoland system can be enabled automatically or manually. For example, some autoland systems are configured to be automatically enabled when, via a decision algorithm, it is determined that the pilot is unable to fly. Some autoland systems are also configured such that any flight crew member or any alert passenger can manually engage the system by pushing a button in the cockpit.
  • Regardless of how the autoland system is enabled, when it is, the autoland system automatically lands the aircraft without user intervention. To do so, the autoland system calculates a flight plan to the most suitable airport, broadcasts intent to air traffic control (ATC), initiates an approach to the runway, and automatically lands the aircraft. The autoland system also automatically applies the aircraft brakes, stops the aircraft, and shuts down the engine(s). As may thus be appreciated, the autoland system comprises numerous avionic systems and components including, for example, the flight management system (FMS), the flight control system (FCS), numerous sensors and system monitors, and generates and supplies commands to manipulate various mechanical systems, such as various flight control system, aircraft landing gear, the aircraft brakes, and the engine(s).
  • Although unlikely, it is postulated that a subsystem or component of the autoland system could fail or otherwise become inoperable when the autoland system is enabled. Should such unlikely event occur, it is possible that manual intervention could potentially assist in correcting the fault and reengaging the autoland system. However, if the autoland system has been enabled because the pilot has become incapacitated, such manual intervention would need to be performed by a non-pilot. This can be very difficult during a critical phase of flight. Furthermore, a non-pilot will likely be unfamiliar with the cockpit layout, further increasing the difficulty to manually intervene in a timely manner.
  • Hence, there is a need for a system and method that can assist a non-pilot in manually intervening, in a timely manner, to take corrective action in the unlikely event one or more subsystems or components of an enabled autoland system fail or otherwise become inoperable. The instant disclosure addresses at least this need.

  • In one embodiment, a system for assisting a non-pilot in taking corrective action includes an aircraft autoland system and a health monitoring system.

    DETAILED DESCRIPTION
  • The following detailed description is merely exemplary in nature and is not intended to limit the invention or the application and uses of the invention. As used herein, the word "exemplary" means "serving as an example, instance, or illustration." Thus, any embodiment described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments. All of the embodiments described herein are exemplary embodiments provided to enable persons skilled in the art to make or use the invention and not to limit the scope of the invention which is defined by the claims. Furthermore, there is no intention to be bound by any expressed or implied theory presented in the preceding technical field, background, brief summary, or the following detailed description.
  • Referring to FIG. 1, one embodiment of a functional block diagram of a system 100 for assisting a non-pilot in taking corrective action is depicted. The system 100, which is preferably installed in an aircraft 102, includes an aircraft autoland system 104, a fault condition database 106, a display device 108, and a health monitoring system 112. As FIG. 1 further depicts, the system 100 may, in some embodiments, additionally include a transmitter 114.
  • The aircraft autoland system 104 is configured, when enabled, to automatically land the aircraft 102 without user intervention. The aircraft autoland system 104 may be enabled either automatically or manually. For example, the aircraft autoland system 104 may be configured to continuously monitor whether a pilot has interacted with the cockpit and to be automatically enabled when the pilot has not interacted with the cockpit for a predetermined amount of time. The aircraft autoland system 104 may be manually enabled by, for example, a user (pilot or non-pilot) manipulating a switch or button 105.
  • Regardless of how the aircraft autoland system 104 becomes enabled, when it is enabled, the various avionic systems and subsystems that comprise the autoland system (e.g., flight management system (FMS), flight control system (FCS) autopilot system, flight director, auto throttle system, braking system, engine controller, etc.) are engaged and controlled, via one or more suitably configured and programmed processors 116, to automatically land the aircraft 102.
  • The fault condition database 106 has a set of fault conditions stored therein. The fault conditions stored in the fault condition database 106 include fault conditions that have been previously determined, and each has been categorized as a fault condition that can be corrected by a non-pilot or a fault condition that cannot be corrected by a pilot. The fault condition database 106 may also include data regarding the location of where, in the cockpit, corrective action may be taken for each fault condition that can be corrected by a non-pilot. The criterion/criteria used to categorize a fault condition as correctable or not correctable by a pilot may vary from aircraft-type to aircraft-type, from cockpit to cockpit, etc., and is based on experience and judgement.
  • The display device 108 is configured, in response to display commands, to render one or more images. To do so, the display device 108 may include any number and type of image generating devices on which one or more avionic displays 118 may be generated. The display device 108 may be fixed or portable. For example, the display device may be affixed to the static structure of the aircraft cockpit as, for example, a Head Down Display (HDD) or Head Up Display (HUD) unit. In some embodiments, the display device 108 may assume the form of a portable device such as a pilot-worn display device, an Electronic Flight Bag (EFB), a laptop, or a tablet computer carried into the aircraft cockpit by a pilot. The display device 108 may be implemented separate from or, as depicted using the dotted lines in FIG. 1, a part of the aircraft autoland system 104.
  • As noted above, at least one avionic display 118 is generated on the display device 108 during operation of the system 100. As used herein, the term "avionic display" is synonymous with the term "aircraft-related display" and "cockpit display" and encompasses displays generated in textual, graphical, cartographical, and other formats. The system 100 can simultaneously generate various types of lateral and vertical avionic displays 118 on which three-dimensional (3D) graphics, text, and other graphics are rendered.
  • The health monitoring system 112 is in operable communication with the aircraft autoland system 104, the fault condition database 106, and the display device 108. The health monitoring system 112, via one or more suitably programmed processors 122, is configured to determine when the aircraft autoland system 104 is enabled. The health monitoring system 112 is additionally configured, when the aircraft autoland system 104 is enabled, to monitor the state of health of the aircraft autoland system 104 to determine if a subsystem or component of the aircraft autoland system 104 is in a fault condition that will inhibit (or prevent) operation of the aircraft autoland system 104. It will be appreciated that the health monitoring system 112 may be any one of numerous health monitoring systems 112 known in the art, either presently or in the future, that have the capability of monitoring the health state of a system.
  • No matter the specific health monitoring system 112 that is implemented, the health monitoring system 112 is additionally configured, upon determining that a subsystem or component of the enabled aircraft autoland system 104 is in a fault condition, to determine if the fault condition can be corrected by a non-pilot. To do so, the health monitoring system 112 compares the fault condition to the set of fault conditions in the fault condition database 106. If, based on this comparison, the health monitoring system 112 determines that the fault condition can be corrected by the non-pilot, the health monitoring system 112 retrieves data regarding the location of where, in the cockpit, corrective action may be taken, and commands the display device 108 to render a 3D cockpit view of instructions for correcting the fault. Preferably, the 3D cockpit view includes at least graphics depicting where, in the cockpit, the corrective action for eliminating the fault is to occur and textual instructions for implementing the corrective action.
  • One simplified example of a suitable 3D cockpit view, for the hypothetical case in which a fault condition can be corrected by pressing and releasing a specific button in the cockpit, is depicted in FIG. 2. As illustrated therein, the 3D cockpit view 202 that is rendered on the display device 108, includes a graphic 204 depicting where in the cockpit the specific switch 206 is located, and the textual instructions for implementing the corrective action - in this case, the corrective action is "PRESS AND RELEASE THIS BUTTON."
  • In addition to the textual instructions, the health monitoring system 112 may, at least in some embodiments, be further configured to generate audible instructions for implementing the corrective actions. In such embodiments, the audible instructions preferably match the textual instructions. Thus, for the simplified example depicted in FIG. 2, the audible instructions would be, "Press and release this button."
  • The health monitoring system 112 is further configured to whether or not the corrective action provided to the non-pilot eliminated the fault and to selectively generate an appropriate alert. Specifically, if the health monitoring system 112 determines that the corrective action did eliminate the fault, the health monitoring system 112 generates an alert indicating that the aircraft autoland system 104 is no longer in the fault condition. Conversely, if the health monitoring system 112 determines that the corrective action did not eliminate the fault, the health monitoring system 112 generates an alert indicating that the aircraft autoland system 104 is still in the fault condition and is inoperable. These generated alerts may be visual, audible, or a combination of both.
  • Referring again to FIG. 1, it was previously mentioned that the system 100, at least in some embodiments, may additionally include a transmitter 114. The transmitter 114, when included, is in operable communication with the health monitoring system 112. The transmitter 114 is coupled to receive, and is configured to transmit, the generated alert(s) to a ground station (not illustrated).
  • Having described the overall functionality of the system 100, a description of a method to assist a non-pilot in taking corrective action that is implemented in the system 100 will be described. The method 300, which is depicted in flowchart form in FIG. 3, represents various embodiments of a method for assisting a non-pilot in taking corrective action. For illustrative purposes, the following description of method 300 may refer to elements mentioned above in connection with FIG. 1. In practice, portions of method 300 may be performed by different components of the described system 100. It should be appreciated that method 300 may include any number of additional or alternative tasks, the tasks shown in FIG. 3 need not be performed in the illustrated order, and method 300 may be incorporated into a more comprehensive procedure or method having additional functionality not described in detail herein. Moreover, one or more of the tasks shown in FIG. 3 could be omitted from an embodiment of the method 300 if the intended overall functionality remains intact.
  • The method 300 starts and the health monitoring system 112 determines if the aircraft autoland system 104 is enabled (302). If it is, then the health monitoring system 112 monitors the state of health of aircraft autoland system 104 (304) and determines if a subsystem or component of the aircraft autoland system 104 is in a fault condition that will inhibit or prevent operation of the aircraft autoland system 104 (306).
  • When the subsystem or component of the enabled aircraft autoland system 104 is in a fault condition that will inhibit or prevent operation of the aircraft autoland system 104, the health monitoring system 112 determines if the fault condition can be corrected by a non-pilot (308). As noted above, this is done by comparing the fault condition to the set of fault conditions in a fault condition database. When the fault condition can be corrected by the non-pilot, the health monitoring system 112 retrieves data regarding the location of where, in the cockpit, corrective action may be taken and commands the display device 108 to render the three-dimensional (3D) cockpit view of instructions for correcting the fault (312). Conversely, when the fault condition cannot be corrected by a non-pilot, the health monitoring system 112 generates an alert indicating that the aircraft autoland system 104 is inoperable (314). This alert may be transmitted to a ground station.
  • As FIG. 3 also depicts, the health monitoring system also determines if the corrective action eliminated the fault (316). If so, an alert is generated indicating that the aircraft autoland system 104 is no longer in the fault condition (318). If not, an alert is generated indicating that the autoland system is still in the fault condition (322). In both instances, the generated alert is transmitted to a ground station.

A general-purpose processor may be a microprocessor, but in the alternative, the processor may be any conventional processor, controller, microcontroller, or state machine. A processor may also be implemented as a combination of computing devices, e.g., 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.
  • The steps of a method or algorithm described in connection with the embodiments disclosed herein may be embodied directly in hardware, in a software module executed by a processor, or in a combination of the two. A software module may reside in RAM memory, flash memory, ROM memory, EPROM memory, EEPROM memory, registers, hard disk, a removable disk, a CD-ROM, or any other form of storage medium known in the art. An exemplary storage medium is coupled to the processor such that the processor can read information from, and write information to, the storage medium. In the alternative, the storage medium may be integral to the processor. The processor and the storage medium may reside in an ASIC.
  • Techniques and technologies may be described herein in terms of functional and/or logical block components, and with reference to symbolic representations of operations, processing tasks, and functions that may be performed by various computing components or devices. Such operations, tasks, and functions are sometimes referred to as being computer-executed, computerized, software-implemented, or computer-implemented. In practice, one or more processor devices can carry out the described operations, tasks, and functions by manipulating electrical signals representing data bits at memory locations in the system memory, as well as other processing of signals. The memory locations where data bits are maintained are physical locations that have particular electrical, magnetic, optical, or organic properties corresponding to the data bits. It should be appreciated that the various block components shown in the figures may be realized by any number of hardware, software, and/or firmware components configured to perform the specified functions. For example, an embodiment of a system or a component may employ various integrated circuit components, e.g., memory elements, digital signal processing elements, logic elements, look-up tables, or the like, which may carry out a variety of functions under the control of one or more microprocessors or other control devices.
  • When implemented in software or firmware, various elements of the systems described herein are essentially the code segments or instructions that perform the various tasks. The program or code segments can be stored in a processor-readable medium or transmitted by a computer data signal embodied in a carrier wave over a transmission medium or communication path.

The code segments may be downloaded via computer networks such as the Internet, an intranet, a LAN, or the like.
  • Some of the functional units described in this specification have been referred to as "modules" in order to more particularly emphasize their implementation independence. For example, functionality referred to herein as a module may be implemented wholly, or partially, as a hardware circuit comprising custom VLSI circuits or gate arrays, off-the-shelf semiconductors such as logic chips, transistors, or other discrete components. A module may also be implemented in programmable hardware devices such as field programmable gate arrays, programmable array logic, programmable logic devices, or the like. Modules may also be implemented in software for execution by various types of processors. An identified module of executable code may, for instance, comprise one or more physical or logical modules of computer instructions that may, for instance, be organized as an object, procedure, or function. Nevertheless, the executables of an identified module need not be physically located together, but may comprise disparate instructions stored in different locations that, when joined logically together, comprise the module and achieve the stated purpose for the module. Indeed, a module of executable code may be a single instruction, or many instructions, and may even be distributed over several different code segments, among different programs, and across several memory devices. Similarly, operational data may be embodied in any suitable form and organized within any suitable type of data structure. The operational data may be collected as a single data set, or may be distributed over different locations including over different storage devices, and may exist, at least partially, merely as electronic signals on a system or network.
  • In this document, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Numerical ordinals such as "first," "second," "third," etc. simply denote different singles of a plurality and do not imply any order or sequence unless specifically defined by the claim language. The sequence of the text in any of the claims does not imply that process steps must be performed in a temporal or logical order according to such sequence unless it is specifically defined by the language of the claim. The process steps may be interchanged in any order without departing from the scope of the invention as long as such an interchange does not contradict the claim language and is not logically nonsensical.
  • Furthermore, depending on the context, words such as "connect" or "coupled to" used in describing a relationship between different elements do not imply that a direct physical connection must be made between these elements. For example, two elements may be connected to each other physically, electronically, logically, or in any other manner, through one or more additional elements.
