Embodiments of the present disclosure relate generally to the display of information onboard an air vehicle and, more particularly, to the display of forecast weather onboard an air vehicle.
Prior to and during flight, it is desirable for the crew of an air vehicle to have information regarding the weather conditions along the planned flight path. Based upon the weather forecast, the crew may take appropriate actions, such as by altering the planned flight path to avoid or minimize the effects of the weather conditions or by altering the manner in which the aircraft is a operated, such as by changing speed and/or altitude, to counter the effects of the weather conditions.
The crew of an aircraft generally receives information regarding a weather forecast prior to a departure of the flight. The crew can examine the forecasted weather conditions and then take into account those forecast weather conditions during the subsequent flight. The information regarding the weather forecast may be provided in various forms, such as textual information coupled, in some instances, with a visual or other graphical representation of the forecasted weather conditions.
Once the aircraft is en route, the weather forecast may be updated so as to take into account changes in the weather forecast and to otherwise provide updated weather information. Since weather forecasts are generally only reliable and therefore valid for some period of time following their generation as a result of the changes in the weather conditions that may occur over time, the time period for which a weather forecast will remain valid is also generally provided, such as in text that accompanies the weather forecast. However, managing the forecast data and integrating that data into situational awareness of the predicted flight impact may disadvantageously increase the workload on the crew.
It would therefore be desirable to provide an improved technique for providing weather forecasts to the crew of an air vehicle. In this regard, it would be desirable to provide an improved technique for providing weather information in a manner that is intuitive and that does not meaningfully increase the workload upon the crew. Additionally, it would be desirable to provide an improved technique for providing weather information to the crew of an air vehicle such that the crew is advised, not only of the current weather conditions, but also future weather conditions.
A method, apparatus and computer program product for displaying forecast weather products with respect to a predicted position of an air vehicle are therefore provided according to embodiments of the present disclosure. in this regard, the method, apparatus and computer program product may display a representation of future weather conditions along with a representation of the anticipated location of the air vehicle during the time period during which the future weather forecast is valid in order to provide context for the future weather information. Additionally, the method, apparatus and computer program product of embodiments of the present disclosure may display the weather information as well as information regarding the time period during which the weather information is valid in a graphical manner that is intuitive to the crew of the air vehicle so as not to distract or otherwise increase the workload upon the crew.
In one embodiment, a method of displaying forecast weather products is provided. The method of this embodiment receives a plurality of weather products with each weather product being associated with a different time period. The method of this embodiment also provides for the display of a representation of the different periods associated with the plurality of weather products and then receives a selection of a time period associated with a respective weather product. The method of this embodiment then provides for a display of a representation of the respective weather product as well as a representation of the anticipated location of the air vehicle relative to the planned flight path during the time period that has been selected. In some embodiments, the method may also provide for the display of a representation of the current location of the air vehicle relative to the planned flight path. By providing for the display of both a weather product and the anticipated location of the air vehicle during a selected time period, the crew of the air vehicle can quickly gather information about the potential impact of the weather conditions upon the flight, not only at the current time, but at future times along the planned flight path. Indeed, the representation of the air vehicle may provide contextual information regarding the anticipated location of the air vehicle to the weather product during each of a number of different time periods.
In another embodiment, an apparatus for displaying forecast weather products is provided. The apparatus includes a memory configured to store a plurality of weather products associated with different time periods. The apparatus also includes a processor, responsive to the memory, configured to provide for the display of a representation of the different time periods associated with the plurality of weather products. The processor is also configured to receive a selection of a time period associated with a respective weather product and to provide for the display of a representation of the respective weather product. In order to provide context to the representation of the respective weather product, the processor may also provide for the display of the representation of an anticipated location of the air vehicle relative to the planned flight path during the time period that has been selected. The processor of one embodiment may also be further configured to provide for the display of a representation of the current location of the air vehicle relative to the planned flight path.
In a further embodiment, a computer program product for displaying forecast weather products is provided. The computer program product includes at least one computer-readable storage unit having computer-readable program code portions stored therein that in response to execution by a processor, cause an apparatus to receive a plurality of weather products associated with different time periods. The computer readable program code portions are also configured, in response to execution by a processor, to cause the apparatus to provide for the display of a representation of the different time periods associated with the plurality of weather products and to receive a selection of a time period associated with a respective weather product. Further, the computer-readable program code portions, in response to execution by a processor, further cause the apparatus to provide for the display of a representation of a respective weather product and a representation of an anticipated location of the air vehicle relative to the planned flight path during the time period that has been selected.
In one embodiment, the display of a graphical representation of the current time in relation to the representation of the different time periods associated with the plurality of weather products may also be provided. In addition, the display of a graphical representation of a forecast time in relation to the representation of the different time periods associated with the plurality of weather products may also be provided with the forecast time being associated with the time period associated with the weather product being displayed. In this regard, an input moving the graphical representation of the forecast time relative to the representation of the different time periods associated with the plurality of weather products may be received. In response to this input, movement of the representation of the anticipated location of the air vehicle may be provided along the planned flight path based upon and in correspondence to the movement of the graphical representation of the forecast time.
In conjunction with the display of the representation of the different time periods, different graphical indicia may be associated with the representations of different time periods to provide different graphical representations of a time period for which a respective weather product is available and of another time period for which the respective weather product is unavailable. The time periods associated with the plurality of weather products may have different lengths. As such, the display of the representation of the different time periods may include a graphical representation of the different lengths of the time periods associated with the plurality of weather products.
In regard to the receipt of a plurality of weather products, at least two sets of weather products may be received at respective times. In this regard, the weather product of one set associated with a respective time period may be inserted into another subsequent set to serve as a weather product associated with the same respective time period in instances in which the subsequent set of weather products that is received fails to include a weather product associated with the respective time period.
Having thus described certain embodiments in general terms, reference will now be made to the accompanying drawings, which are not necessarily drawn to scale, and wherein:
Embodiments of the present disclosure now will be described more fully hereinafter with reference to the accompanying drawings, in which some, but not all embodiments of the disclosure are shown. Indeed, these embodiments may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements. Like numbers refer to like elements throughout.
Referring now to
A set of forecast weather products generally includes a plurality of weather products that provide information regarding the anticipated weather conditions associated with the planned flight path of the air vehicle 10. Each weather product of a set of weather products is generally associated with and valid for a different time period. In this regard, each weather product is generally valid for a predefined time period. As described below, each weather product of a set of weather products may be valid for a respective time period having the same length of time or may be valid for time periods that differ from one another. By way of example, for a flight that is scheduled to depart from Miami at 12:00 noon Eastern Time and to arrive in Seattle, Wash. at 5:30 p.m. Eastern Time, the set of weather products of one embodiment may include a first weather product that is valid from 11:00 a.m. Eastern Time until 1:00 p.m. Eastern Time, a second weather product that is valid from 1:00 p.m. Eastern Time until 3:00 p.m. Eastern Time, a third weather product that is valid from 3:00 p.m. Eastern Time until 5:00 p.m. Eastern Time and a fourth weather product that is valid from 5:00 p.m. Eastern Time until 7:00 p.m. Eastern Time. As such, the entire time period during which the air vehicle is anticipated to be en route from the origin to the destination is encompassed by the set of weather products.
The plurality of weather products generally provide weather information indicative of the anticipated weather conditions associated with the planned flight. The forecast weather products of one embodiment include weather information relevant to a region through which the planned flight path extends including, for example a region that extends a predefined distance on either side of the planned flight path. As such, the forecast weather products provide weather information to the crew of the air vehicle 10 regarding the weather conditions on the planned flight path as well as weather conditions in the near vicinity of the planned flight path such that the crew may take appropriate measures to accommodate the anticipated weather conditions. Various weather products are available with one example of a weather product being the Collaborative Convective Forecast Product (CCFP). In addition to the weather products, the air vehicle 10 may receive the current date and time and/or updated position information for the air vehicle from other systems onboard the air vehicle. See, for example, blocks 21 and 22 of
A graphical representation 34 of the current time may also be displayed in relation to the representation 32 of different time periods associated with the plurality of weather products. See block 25 of
Following the display of the representation 32 of the different time periods associated with the plurality of weather products, a check may be preformed to determine if a selection of a time period has been received and, when a selection of a time period associated with a respective weather product has been received, an appropriate display may be generated. See blocks 26 and 27 of
In addition to displaying the representation 36 of the respective weather product in relation to the planned flight path 30, a representation 38 of an anticipated location of the air vehicle 10 relative to the planned flight path during the time period that has been selected is also provided. See block 29 of
In addition to providing a representation 34 of the current time relative to the different time periods that are associated with the plurality of weather products, a representation 40 of the time that is associated with the weather product that is currently being displayed may also be provided in relation to the representations 32 of the different time periods in instances in which the selected time period is in advance of the current time, such as shown in
In order to illustrate the different displays that may be provided as different time periods that are associated with different weather products are selected,
As noted above, the display that is provided may be changed by the selection of a different time period. However, the display may also be changed by selecting the icon 40 representative of the time associated with the predicted aircraft position 38 and then moving the icon, such as by dragging the icon, relative to the timeline set forth by the representations 32 of the different time periods. Relative to the display depicted in
Since the same weather product is generally valid during the entirety of the respective time period, the representation 36 of the weather product does not generally change while the icon 40 representative of the selected time is moved across a single time period. However, upon movement of the icon representative of the selected time from one time period to another time period, such as from the second time period extending between 1300 and 1500 UTC time to the third time period extending between 1500 and 1700 UTC time, the representation of the weather product would also change from that shown in
In the foregoing embodiments, each time period associated with the plurality of weather products has the same length, e.g., two hours. However, the time periods associated with the plurality of available weather products may have different lengths. For example, the time periods associated with the CCFP weather products may differ. In instances in which the time periods associated with the plurality of weather products have different lengths, the display of the representation 32 of the different time periods may include a graphical representation of the different lengths of the time periods associated with the plurality of weather products. By way of example,
In the embodiments described above, the plurality of weather products include weather products for each of a number of contiguous time periods. In some embodiments, however, a weather product may be unavailable for one of the time periods, even though weather products are available for the other time periods. In this instance, different graphical indicia may be associated with the representation 32 of the different time periods to provide different graphical representations of a time period for which a respective weather product is available and of another time period for which the respective weather product is unavailable. With reference to
As discussed above in conjunction with
The representation 32 of the time periods associated with the weather products may be provided in such a manner to alert a crew member that the weather product associated with one or more time periods has not been updated, but is instead dependent upon the weather product from a prior set of weather products. For example, the time period associated with the weather product that is being recycled from the prior set of weather products may be graphically represented in a variety of manners that differ from the representations of the other time periods, such as in terms of color, shading, labeling or the like. With respect to
The method of displaying forecast weather products in relation to a planned flight path 30 may be automated and, as such, may be implemented by a computer 50, such as depicted in
In an exemplary embodiment, the computer 50 of
The computer 50 can also include a display 56 for presenting the displays of
In one embodiment, the processing circuitry may include a processor 52. The processor may be embodied in a number of different ways. For example, the processor may be embodied as various processing means such as a microprocessor or other processing element, a coprocessor, a controller or various other computing or processing devices including integrated circuits such as, for example, an ASIC (application specific integrated circuit), an FPGA (field programmable gate array), a hardware accelerator, or the like. In an exemplary embodiment, the processor may be configured to execute instructions stored in the memory device 54 or otherwise accessible to the processor. As such, whether configured by hardware or software methods, or by a combination thereof, the processor may represent an entity (e.g., physically embodied in circuitry) capable of performing operations according to embodiments of the present invention while configured accordingly. Thus, for example, when the processor is embodied as an ASIC, FPGA or the like, the processor may be specifically configured hardware for conducting the operations described herein. Alternatively, as another example, when the processor is embodied as an executor of software instructions, the instructions may specifically configure the processor to perform the operations described herein.
Embodiments of method and apparatus of the present disclosure may therefore be practiced using a computer 50 such as depicted in
As will be appreciated, any such stored computer program instructions may be loaded onto a computer or other programmable apparatus (i.e., hardware) to produce a machine, such that the instructions which execute on the computer or other programmable apparatus implement the functions specified in the flowchart block(s) or step(s). These computer program instructions may also be stored in a computer-readable medium comprising memory that may direct a computer or other programmable apparatus to function in a particular manner, such that the instructions stored in the computer-readable memory produce an article of manufacture including instructions to implement the function specified in the flowchart block(s) or step(s). The computer program instructions may also be loaded onto a computer or other programmable apparatus to cause a series of operational steps to be performed on the computer or other programmable apparatus to produce a computer-implemented process such that the instructions which execute on the computer or other programmable apparatus provide steps for implementing the functions specified in the flowchart block(s) or step(s).
Many modifications and other embodiments of the disclosure set forth herein will come to mind to one skilled in the art to which this disclosure pertains having the benefit of the teachings presented in the foregoing descriptions and the associated drawings. Therefore, it is to be understood that the disclosure is not to be limited to the specific embodiments discussed above and that modifications and other embodiments are intended to be included within the scope of the appended claims. Although specific terms are employed herein, they are used in a generic and descriptive sense only and not for purposes of limitation.
