The technical field relates generally to systems and methods for providing a checklist used in operation of a vehicle.
Pilots have traditionally utilized paper-based checklists in the operation of the aircraft. These checklists often require the pilot or other crew to analyze multiple components and/or systems before proceeding. Furthermore, the checklists may direct the pilot or other crew to take unnecessary actions or perform redundant tasks. Again, time is often wasted in performing these operations.
As such, it is desirable to present a checklist to an operator of a vehicle which will reduce the time and effort needed to perform the tasks of the checklist. In addition, other desirable features and characteristics will become apparent from the subsequent summary and detailed description, and the appended claims, taken in conjunction with the accompanying drawings and this background.
A method for providing a checklist to an operator of a vehicle includes the step of sensing operation of at least one component of the vehicle. The method further includes the step of generating a checklist based at least in part on the sensed operation of the at least one component of the vehicle. The method also includes the step of displaying the checklist on a display for use by the operator of the vehicle.
A system for providing a checklist to an operator of a vehicle includes a processor. The processor is configured to sense operation of at least one component of the vehicle and generate a checklist based on the sensed operation of the at least one component of the vehicle. The system also includes a display in communication with the processor and is configured to display the checklist for use by the operator of the vehicle.
Other advantages of the disclosed subject matter will be readily appreciated, as the same becomes better understood by reference to the following detailed description when considered in connection with the accompanying drawings wherein:
Referring to the Figures, wherein like numerals indicate like parts throughout the several views, a system 100 and methods 200 for providing a dynamic checklist to an operator of a vehicle 102 are shown and described herein.
The vehicle 102 of the illustrated embodiment is an aircraft (not separately numbered) such as an airplane (not separately numbered). However, the system 100 and methods 200 described herein may also be used with vehicles and fixed-systems other than an airplane, including, but certainly not limited to, a helicopter, a boat, a chemical plant, a factory, a power plant, or any other complex machinery.
The vehicle 102 includes at least one component 103 related to operation of the vehicle 102. In the illustrated embodiment, the vehicle 102 includes a plurality of components 103. For instance, when the vehicle 102 is an aircraft, the components 103 may include batteries, an auxiliary power unit (“APU”), landing gear, flaps, brakes, electrical loads, engines, a fuel tank, and/or external lights. Of course, the preceding list of components 103 of an aircraft is not intended to be exhaustive. Numerous other components 103 may be utilized in operation of the vehicle 102.

The system 100 of the illustrated embodiment further includes a display 106 in communication with controller 104. The display 106 presents visual information, data, and/or instructions to the operator. Particularly, the display 106 operates from instructions provided by the controller 104 and outputs information and data provided by the controller 104. Numerous suitable devices may be utilized as part the display 106, including, but not limited to, a cathode ray tube (“CRT”), light-emitting diodes (“LED”), a plasma panel, and a liquid crystal display (“LCD”). While the system 100 of the illustrated embodiment shows the display 106 as the only output device, other output devices, such as a speaker, may also or alternatively be utilized.
The system 100 of the illustrated embodiment may further include an input device 108 for receiving input from the operator or other user. The input device 108 is in communication with the controller 104 such that input received at the input device 108 may be transmitted to the controller 104. In the illustrated embodiment, the input device 108 is a touch screen panel overlayed with the display 106.
The controller 104 is in communication with the at least one component 103 of the vehicle 102. As such, the controller 104 may receive information, data, and/or commands from the at least one component 103, and vice-versa. Communication with the component 103 may be achieved via direct connection between the controller 104 and the component 103, wireless communications, or communications through one or more intermediary devices (not shown). Those skilled in the art realize any number of techniques to facilitate such communication.
The system 100 described above is capable of and may be configured to implement the steps of the method 200 described below. However, those skilled in the art realize that other systems and hardware may alternatively be used to implement the method 200. Furthermore, the system 100 described above may be configured to perform other items, besides the various steps of the method 200 described below.

Sensing the operation of the components 103 may be performed differently based on each individual component 103 and the “operation” of the component 103 that is being sensed. In one instance, the step of sensing operation of the component 103 may be further defined as whether or not the component is functional. For example, if the component 103 is a battery, sensing operation of the battery may include sensing whether the battery has a sufficient charge to provide current to various loads of the vehicle 102. In another example, if the component 103 is an engine, sensing operation of the engine may include analyzing one or more signals from the engine to see if the engine is operating properly. The sensing of the operation of each individual component 103 may include sensing the lack of communication with the component 103. For example, if the component 103 fails, is destroyed, and/or is otherwise removed, communication between the component 103 and the controller 104 may be interrupted.
In another instance, sensing the operation of the component 103 may also be defined as sensing the state of the component 103. For example, if the component 103 is landing gear, sensing the operation of the landing gear may be determining whether the landing gear is “up”, “down”, or between states. In another example, if the component 103 is aircraft flaps, sensing the operation of the flaps may be receiving and analyzing a signal which indicates whether the flaps are “set for landing” or “retracted”. Furthermore, sensing the state of the component 103 may involve analyzing signals from multiple sensors (not numbered) for that component 103.
The method 200 also includes the step 204 of generating a checklist 300 for use by the operator of the vehicle. The checklist 300 presents various items for the operator to perform. Accordingly, the method 200 further includes the step 206 of displaying the checklist 300 on the display 106, as shown in
By generating the checklist 300 based in part on the actual, sensed status of vehicle 102 components 103, unnecessary and otherwise redundant actions, including the use of multiple checklists, are reduced. This saves crucial time and effort, especially in time sensitive circumstances, e.g., the failure of a critical component of the vehicle 102.
The checklists 300 may be divided into two types: (1) regularly scheduled checklists and (2) event-driven checklists. For example, a regularly scheduled checklist may be a pre-takeoff checklist or a pre-landing checklist. An event-driven checklist may be a checklist that is utilized in response to one or more events. For example, there may be an event-driven checklist for the loss of an engine of the aircraft. However, the checklist 300 may have properties of both a regularly scheduled checklist and an event-driven checklist, as described further below.
The checklist 300 generated by the method 200 is based, at least in part, on the sensed operation of the at least one component 103 of the vehicle 102. That is, in the illustrated embodiment, the sensed operation of the component 103 or components 103 are utilized in generating one or more items 302 of the checklist 300. Said yet another way, whether or not an item 302 appears on the checklist 300 may be dependent on the sensed operation of one or more components 103.
For example, in some aircraft, if a certain electrical bus is inoperative, then an automatic pressurization controller, to maintain cabin pressure, is not receiving electrical power. As such, pressurization may have to be set manually. As applied to the method 200, if the component 103 (i.e., the electrical bus) is sensed to be inoperative, then the checklist 300 may include the item 312 of “manually setting cabin pressurization”.
The method may further include the step 208 of changing the checklist 300 based at least in part on a change in the sensed operation of the at least one component 103 of the vehicle 102. The changing of the checklist 300 may include altering at least one of the items 302 based at least in part on a change in the sensed operation of the at least one component 103 of the vehicle 102. Altering at least one of the items 302 may include, but is not limited to, adding an item 302, deleting an item 302, and/or modifying an item 302. For example, with reference to
The items 302 of the checklist 300 may be ranked in a prioritized order. That is, the items may be arranged in an order of which item must be done first, second, and so on. Furthermore, ranking the items 302 in a prioritized order may be based at least in part on the sensed operation of the at least one component 103 of the vehicle 102. Moreover, the items 302 may be arranged and displayed on the display 106 in the prioritized order. In the illustrated embodiment, the highest prioritized item 302 (i.e., the first item) is listed at a top of the display 106, the next highest prioritized item 302 is immediately below the highest prioritized item 302, and so on.
For instance, in an emergency situation, the items 302 may be arranged such that the first item to be performed is critical to the preservation of the vehicle 102 and/or the health and safety of the user. As just one example, if it is sensed that cabin pressure of the aircraft is failing, the checklist 300 may be reprioritized such that first item 302 is for the user (and the rest of the crew) to don an oxygen mask (before they are incapacitated). As another example, if it is sensed that an autopilot mechanism of the aircraft has failed, the checklist 300 may be reprioritized such that first item 302 is to take manual control of the aircraft.
Other criteria for arranging the items 302 of the checklist 300 may also be utilized. In one example, the items 302 may be grouped by overall objective. In another example, the items 302 may be grouped by vehicle 100 “system” so that redundant and/or contradictory steps are avoided. In yet another example, the items 302 may be grouped by “cockpit flow”, such that the items are arranged intuitively based on where an action or analysis must take place in the cockpit of the vehicle 102. In addition, the items 302 of the checklist 300 may be re-ordered according to the required interactions of whatever components 103 are functional. For example, hydraulic systems may need to be energized before brakes are required.
As described above, the checklist 300 may be dynamically changed and/or reprioritized. As such, a regularly scheduled checklist may take on properties of an event-driven checklist. For example, if a pre-landing checklist was being utilized when it is sensed that an essential electrical bus has failed, the items of the checklist may be amended, deleted, changed, and/or reprioritized accordingly.
The method 200 may further include the step (not shown in
The input received may be an acknowledgement that an item 302 has been completed. This may be accomplished by touching a check-box 304 on the touch screen display 106. However, other suitable techniques of acknowledgement will be recognized by those skilled in the art. After acknowledgement is received, the displayed item 302 may be modified in some way to show that the item 302 has been completed and/or acknowledged. For example, a check-mark may be placed in the check-box 304, as shown in
The input received may be a command to be sent to a component 103 of the vehicle 102. As such, the method may also include the step of sending a command to at least one component 103 of the vehicle 102 in response to said receiving the input from the operator of the vehicle 102. In the illustrated embodiment, the command is received by the controller 104, processed, and then sent to the proper component 103.
