## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention pertains generally to the field of aircraft display units that present information of aircraft position and flight plan information to a viewer.
2. Description of the Related Art
Visual displays units are employed in passenger cabins of an aircraft to provide passengers with flight information about the current flight. While in flight, the passenger may look at the screen of the display unit to determine the progress of the flight and the current position of the aircraft in relation to, for example, geographic boundaries, the departure airport, and the destination airport. Depending on the presentation, the passenger may observe the initial flight plan, the actual ground track of the aircraft, and the position of the aircraft along the flight plan. Cabin display units provide for a convenient way in which passengers are presented with flight information instead of having to ask others.
For the owners or operators of a fleet of aircraft, knowledge about the location of one or more aircraft in the fleet may be considered essential knowledge when, for example, planning for the future utilization of the fleet aircraft. Moreover, if he or she is on board the aircraft or spends any considerable time flying in aircraft, information about the location(s) of the fleet may be limited to the flight information of the current flight of the aircraft he or she is on.

The display unit 110 could be comprised of a unit on which passengers in the cabin may view and/or track their flight's progress such as, but not limited to, seatback display units, display units stowed in the armrests of passenger seats, and/or display units attached to a cabin wall and/or ceiling and viewable to multiple passengers.
In addition to the display units found installed in an aircraft, the disclosures herein may apply to both portable or non-portable devices such as, but not limited to, tablet devices (e.g., an iPad developed by Apple, Inc., devices in which an Android operating system developed by Google Inc. is installed, etc. . . . ), electronic flight bags, smartphones, laptop computers, and/or desktop computers irrespective of location (i.e., internal or external to the aircraft) with which the IG 160 is in communication. As embodied herein, the display unit 110 may receive an image data set generated by the IG 160 using the methods disclosed herein; moreover, as discussed in the following paragraph, the display unit 110 may provide input to the IG 160 if it is integrated with the manual input device 120.
In an embodiment of FIG. 1, the manual input device 120 could comprise any source for facilitating a viewer's interaction with graphical user interfaces (singularly, “GUI”) referred to as interactive widgets that are displayed on the surface of the display unit 110; as embodied herein, the terms “user” and “viewer” are synonymous. The manual input device 120 may include any device that allows for the manual selection of widgets and/or entry of data. Such devices could include, but are not limited to, a tactile device (e.g., keyboard, cursor control device, etc. . . . ) and/or speech recognition systems. Also, the manual input device 120 could be integrated with the display unit 110 if it is, for example, configured to receive pilot input (e.g., touch screen display); tablet devices and smartphones integrate the manual input device 120 with the display unit 110. As embodied herein, the manual input device 120 may provide input representative of a viewer's selection to the IG 160.
In an embodiment of FIG. 1, the terrain data source 130 could comprise any source of terrain data, obstacle data, or both. As embodied herein, a terrain data source 130 may include, but is not limited to, a terrain database configured to store terrain data contained in digital elevation models (“DEM”). Generally, the terrain data of a DEM is stored as grids, and each grid represents an area of terrain and is commonly referred to as a terrain cell. The terrain data source 130 is a data source known to those skilled in the art. As embodied herein, the IG 160 may retrieve terrain data representative of a spherical surface of the Earth from the terrain data source 130.
In an embodiment of FIG. 1, the VAFIDS 140 could be any source(s) from which flight information such as, but not limited to, flight plan and/or aircraft position information of a viewer aircraft may be stored and provided to or retrieved by the IG 160. One VAFIDS 140 is commonly known as a flight management system (“FMS”). The FMS may perform a variety of functions performed to help the crew in the management of the flight, and such functions are known to those skilled in the art. In the performance of its many functions, the FMS may receive navigation data from one or more navigation systems containing information regarding the current state of the aircraft. The navigation system could be comprised of, but is not limited to, an air/data system, an attitude heading reference system, an inertial guidance system (or inertial reference system), a global navigation satellite system (“GNSS”) (or satellite navigation system such as the global positioning system (“GPS”)), and a radio altimeter system, all of which are known to those skilled in the art. As embodied herein, the navigation system could provide navigation information including, but not limited to, geographic position, altitude, attitude, speed, vertical speed, and heading. As embodied herein, aircraft position could be comprised of geographic position (e.g., latitude and longitude coordinates) and altitude, and direction may be derived from either geographic position, aircraft position, or both.
It should be noted that, as embodied herein for any unit, device, source, or system in an aircraft including the FMS and/or navigation system, data could be comprised of any analog or digital signal, either discrete or continuous, which could contain information. As embodied herein, aircraft could mean any vehicle which is able to fly through the air or atmosphere including, but not limited to, lighter than air vehicles and heavier than air vehicles, wherein the latter may include fixed-wing and rotary-wing vehicles.
In an embodiment of FIG. 1, the external flight information data source 150 could be any source that provides flight plan and/or aircraft position of target aircraft of the aircraft network that is sent to the IG 160 via a communications interface such as, but not limited to, a datalink. The external flight information data source 150 could be comprised of a target aircraft flight information data source (“TAFIDS”) 152 and/or a network database 154. The TAFIDS 152 could be comprised of a flight information data source such as an FMS that is installed in a target aircraft; the TAFIDS 152 could transmit flight information to the viewer aircraft and/or network database 154 via a datalink of the target aircraft. The network database 154 could be any database configured to receive and/or store flight information received real-time from one or more aircraft of the network. When requested by the viewer aircraft, the network database 154 may provide flight information of one or more aircraft in the network.
In an embodiment of FIG. 1, the IG 160 may be any electronic data processing unit which executes software or source code stored, permanently or temporarily, in a digital memory storage device as discussed above. The IG 160 may be driven by the execution of software or source code containing algorithms developed for the specific functions embodied herein. Common examples of electronic data processing units are microprocessors, Digital Signal Processors, Programmable Logic Devices, Programmable Gate Arrays, and signal generators; however, for the embodiments herein, the term generator is not limited to such processing units and its meaning is not intended to be construed narrowly. For instance, a processor could also consist of more than one electronic data processing units. As embodied herein, the IG 160 could be a processor(s) used by or in conjunction with any other system of the aircraft.
The IG 160 may be programmed or configured to receive as input data representative of information obtained from the display unit 110 (if integrated with an input device), the manual input device 120, the terrain data source 130, the VAFIDS 140, and through a datalink. A datalink could be comprised of those interface system(s) configured to receive and provide data and/or signals from source(s) external to the aircraft including, but not limited to, ground stations and satellites.
As embodied herein, the terms “programmed” and “configured” are synonymous with respect to the execution of software or source code developed for the specific functions and methods embodied herein. The IG 160 may be electronically coupled to systems and/or sources to facilitate the receipt of input data; as embodied herein, operatively coupled may be considered as interchangeable with electronically coupled. The IG 160 may be programmed to execute the methods embodied herein and discussed in detail below. The IG 160 may be programmed to provide output data and/or signal data to the display unit 110 and/or the VAFIDS 140. The IG 160 may be electronically coupled to systems and/or units to facilitate the providing of output data representative of a procedure. It is not necessary that a direct connection be made; instead, such receipt of input data and the providing of output data could be provided through a data bus or through a wireless network.
The advantages and benefits of the embodiments discussed herein may be illustrated by showing examples in FIGS. 2A through 2F of how flight information about network aircraft may be acquired and presented to the viewer of the display unit 110. In the following examples, it will be assumed that the viewer is onboard the viewer aircraft taking off from Los Angeles International Airport (“LAX”) in Los Angeles, Calif., United States and landing in Denver International Airport (“DEN”) located in Denver, Colo., United States. Also, it will be assumed that the viewer has access to a display unit integrated with a manual device located in the seatback of the seat in front of the viewer. Although the following examples will be drawn to an LAX-DEN flight, these examples are provided for the sole purpose of illustration and not limitation.
Referring to FIG. 2A, flight information is presented as an image displayed on the display unit 110. As illustrated, the image is comprised of the sky, a spherical surface of Earth, a curved flight path, and a symbol of an aircraft. The sky and spherical surface form a background that is overlaid by the curved flight path and aircraft symbol. The view, selectable by a pilot using a user-interactive menu via the manual input device 120, is forward-facing (i.e., looking towards the front of the aircraft) and pointed in the direction of the aircraft's heading; the view looking in the direction of the aircraft's heading will be considered herein as the default view.
In the example of FIG. 2A, assume that the viewer aircraft is located above Los Angeles (i.e., the aircraft has just departed LAX), and that the flight plan initially approved by air traffic control is still the active flight plan. As embodied herein, the IG 160 may receive data from the VAFIDS 140 representative of flight information comprised of the active flight plan and aircraft position. Based upon the data and the direction of the view, the IG 160 may retrieve the terrain data corresponding to the flight information, generate an image data set representative of the image shown in FIG. 2A, and provide it to the display unit 110; here, the curved flight path may be representative of and coincide with the active flight plan, and the aircraft symbol may be representative of and coincide with the aircraft position.
In the example of FIG. 2B, assume that there has been a change in the active flight plan of the viewer aircraft due to inclement weather ahead; that is, the viewer flight plan is no longer the active flight plan. Because the VAFIDS 140 may be configured to provide flight information data representative of the active flight plan to the IG 160, a change in the active flight plan with cause a change in the appearance of the curved flight path. A comparison of FIGS. 2A and 2B indicates the change in the appearance of the curved flight path.
In the example of FIG. 2C, assume that the viewer aircraft has flown to a location somewhere in between LAX and DEN, and that there has been no change in the active flight plan; however, the viewer has selected a rearward-facing view in an approximately opposite direction of the aircraft's heading through the use of the manual input device 120. Because the position of the aircraft has changed from FIG. 2B and because the view had changed, the three-dimensional scene has changed. A comparison of FIGS. 2B and 2C indicates the change in the aircraft position and the change in the three-dimensional scene.
For the example of FIG. 2D, assume that the viewer wants to view flight information of a target aircraft of the network aircraft. Here, through the use of a user-interactive menu, he or she may request a target aircraft by selecting an aircraft-specific identifier through the use of the manual input device 120. In this example, it will be assumed that the target aircraft is taking off from Salt Lake City International Airport (“SLC”) in Salt Lake City, Utah, United States and landing in Phoenix Sky Harbor International Airport (“PHX”) located in Phoenix, Ariz., United States.
In the example of FIG. 2D, assume that the target aircraft is located above Salt Lake City (i.e., the aircraft has just departed SLC), and that the flight plan initially approved by air traffic control is still the active flight plan. As embodied herein, the IG 160 of the viewer aircraft may receive via its datalink flight information data from the external flight information data source 150, where such data could be representative of flight information comprised of the active flight plan and aircraft position of the target aircraft. After receiving this data and the direction of the view, the IG 160 may retrieve the terrain data corresponding to the target aircraft flight information, generate an image data set representative of the image shown in FIG. 2D, and provide it to the display unit 110; here, the curved flight path may be representative of and coincide with the active flight plan of the target aircraft, and the aircraft symbol may be representative of and coincide with the aircraft position of the target aircraft.
In the example of FIG. 2E, assume that the target aircraft has flown to a location somewhere in between SLC and PHX, and that there has been no change in the active flight plan; however, the viewer has selected a rearward-facing view. Because the position of the aircraft has changed from FIG. 2D and because the view had changed, the three-dimensional scene has changed. A comparison of FIGS. 2D and 2E indicates the change in the aircraft position and the change in the three-dimensional scene.
In the example of FIG. 2F, assume that the target aircraft is approaching PHX, and that there has been no change in the active flight plan; however, the viewer has selected a forward-facing view (or a default view). Because the position of the aircraft has changed from FIG. 2E and because the view had changed, the three-dimensional scene has changed. A comparison of FIGS. 2E and 2F indicates the change in the aircraft position and the change in the three-dimensional scene.
In the preceding examples of FIGS. 2A through 2F, flight information of only one aircraft was provided. As embodied herein, flight information of a second or more aircraft of the network may be provided for each aircraft appearing in the selectable view.
Referring to FIG. 3A (FIG. 2B with the SLC-PHX flight path and aircraft symbol in the background), assume that the scenario provided in FIG. 2B applies in which the selectable view is pointed in the direction of the aircraft's heading. In addition, the viewer has selected to view the target aircraft determined to be within the selectable view. Assume that only the target aircraft that will be determined to be within the selectable view is the target aircraft of FIGS. 2D through 2F flying the SLC-PHX leg. As embodied herein, the IG 160 may receive data from both the VAFIDS 140 representative of flight information comprised of the active flight plan and aircraft position of the viewer aircraft and the external flight information data source 150, where such data could be representative of flight information comprised of the active flight plan and aircraft position of each target aircraft. Because the viewer is interested in more than one aircraft in the fleet, a focal aircraft may be selected.
In the example of FIG. 3A, the viewer has selected the viewer aircraft to be the focal aircraft as shown by its predominance in the scene. Based upon the data and the direction of the view, the IG 160 may retrieve the terrain data corresponding to the flight information of the focal aircraft (here, the viewer aircraft flying the LAX-DEN leg), determine that the non-focal aircraft appears within the selectable view, generate an image data set representative of the image shown in FIG. 3A, and provide it to the display unit 110; here, the curved flight paths may be representative of and coincide with the active flight plans of both the focal aircraft and each non-focal aircraft determined to be within the selectable view, and the aircraft symbol may be representative of and coincide with the aircraft positions of the focal and non-focal aircraft.
Referring to FIG. 3B, (FIG. 2D with the LAX-DEN and aircraft symbol in the background) assume that the scenario provided in FIG. 2D applies; that is, assume that the viewer selects that focal aircraft to be the target aircraft of the network which happens to be the aircraft flying the SLC-PHX leg of FIGS. 2D through 2F. Also, assume that the viewer wants to view the viewer aircraft flying the LAX-DEN leg from the perspective of the focal aircraft if it appears in the view selectable by the viewer. As embodied herein, the IG 160 may receive data from both the VAFIDS 140 representative of flight information comprised of the active flight plan and aircraft position of the viewer aircraft and the external flight information data source 150, where such data could be representative of flight information comprised of the active flight plan and aircraft position of the target aircraft.
In this example, the viewer has selected the target aircraft to be the focal aircraft as shown by its predominance in the scene. Based upon the data and the direction of the view, the IG 160 may retrieve the terrain data corresponding to the flight information of the focal aircraft (here, the target aircraft flying the SLC-PHX leg), determine that the non-focal aircraft appears within the selectable view, generate an image data set representative of the image shown in FIG. 3B, and provide it to the display unit 110; here, the curved flight paths may be representative of and coincide with the active flight plans of both the focal aircraft and each non-focal aircraft determined to be within the selectable view, and the aircraft symbol may be representative of and coincide with the aircraft positions of the focal and each non-focal aircraft.
The drawings of FIG. 4 depict flowchart 200 disclosing an example of a method for presenting flight information of a plurality of aircraft, where the IG 160 may be programmed or configured with instructions corresponding to the following modules embodied in the flowchart. Also, the IG 160 may be a processor of a module such as, but not limited to, a printed circuit board having one or more input interfaces to facilitate the two-way data communications of the IG 160, i.e., to facilitate the receiving and providing of data. As necessary for the accomplishment of the following modules embodied in the flowchart, the receiving of data is synonymous and/or interchangeable with the retrieving of data, and the providing of data is synonymous and/or interchangeable with the making available or supplying of data.
Flowchart 200 begins in FIG. 4 with module 202 with the receiving of request data corresponding to a selection, where the selection may be made from a user-interactive menu via the manual input device 120. As embodied herein, the manual input device 120 could be the display unit with an integrated manual input device. The request could include a request for flight information of the viewer aircraft, flight information of one or more target aircraft, or both. If the user wishes to see flight information of one or more target aircraft, an aircraft-specific identifier of the each target aircraft could be included in the request. This first request could also include information corresponding to a view that the viewer has selected; if no view has been selected, the viewer could be making an implied selection of a view corresponding to a default view.
In addition, the first request could also include information corresponding to a focal aircraft which may be the main aircraft in the view appearing approximately front and center in the three-dimensional scene of the image; if no focal aircraft has been selected, the viewer could be making an implied selection that the focal aircraft corresponds to the viewer aircraft.
The flowchart continues with module 204 with the receiving of flight information data of the viewer aircraft from the VAFIDS 140 when the first request includes the viewer aircraft. In another embodiment, a request including the viewer aircraft could be made by a viewer not located on the viewer aircraft and/or through the manual input device 120 that is a portable device (e.g., iPad). If so, in order for the IG 160 to receive flight information data from the VAFIDS 140, the IG 160 could be programmed to send a request to the VAFIDS 140 of the viewer aircraft, where a signal representative of this request is then transmitted the VAFIDS 140 via at least one datalink or communications interface of the viewer aircraft. In response to this request, the IG 160 could then receive the flight information data from the VAFIDS 140.
Alternatively, the IG 160 could be programmed to send a request to the network database 154, where a signal representative of this request is then transmitted to the network database 154. In response to this request, the IG 160 could then receive the flight information data of the viewer aircraft from the network database 154.
The flowchart continues with module 206 with the sending of request for flight information data of each target aircraft included in the first request. As embodied herein, a signal representative of this request could be transmitted via a datalink(s) to one or more external flight information data sources 150 comprised of at least one TAFIDS 152 and/or the network database 154 configured to receive and store real-time flight information from one or more aircraft of the network.
The flowchart continues with module 208 with the receiving of the second flight information data of each target aircraft in the request in response to the request sent in module 206. As embodied herein, the IG 160 could receive via a datalink(s) the flight information data of each target from one or more external flight information data sources 150.
The flowchart continues with module 210 with the retrieving of terrain data representative of a spherical surface of the Earth. The retrieval of terrain data could correspond to both the selectable view and the active flight plan of the focal aircraft.
The flowchart continues with module 212 with the generating of an image data set as a function of the terrain data, the flight information of the viewer aircraft if included in the first request, and the flight information of the target aircraft for each target aircraft included in the request. As embodied herein, the viewer aircraft or one target aircraft could be requested. Here, the image data set may be representative of a three-dimensional scene of the selectable view comprised of the sky, the spherical surface of the Earth, a first aircraft symbol, and a first curved flight path. The background of the scene may be comprised of the sky and the spherical surface of the Earth. The first curved flight path could overlay the background of the three-dimensional scene, where the path could be three-dimensional and representative of and coinciding with the active flight plan of the focal aircraft; similarly, the first aircraft symbol could overlay the background of the three-dimensional scene, where the symbol could be three-dimensional and representative of and coincide with the position of the focal aircraft.
In an additional embodiment, the image data set could be further representative of at least one second curved flight path of each non-focal aircraft determined by the IG 160 to be within the selectable view. Each second curved flight path could overlay the background of the three-dimensional scene, where each such path could be three-dimensional and representative of and coincide with active flight plan of its corresponding non-focal aircraft; similarly, each such second aircraft symbol could overlay the background of the three-dimensional scene, where each such symbol could be three-dimensional and representative of and coincide with the position of its corresponding non-focal aircraft.
The flowchart continues with module 214 with the providing of the image data set to the display unit, whereby the view of the three-dimensional scene represented in the image data set is presented on the screen of the display unit. Then, the flowchart proceeds to the end.
It should be noted that the method steps described above may be embodied in computer-readable media as computer instruction code. It shall be appreciated to those skilled in the art that not all method steps described must be performed, nor must they be performed in the order stated.
As used herein, the term “embodiment” means an embodiment that serves to illustrate by way of example but not limitation.
It will be appreciated to those skilled in the art that the preceding examples and embodiments are exemplary and not limiting to the scope of the present invention. It is intended that all permutations, enhancements, equivalents, and improvements thereto that are apparent to those skilled in the art upon a reading of the specification and a study of the drawings are included within the true spirit and scope of the present invention. It is therefore intended that the following appended claims include all such modifications, permutations and equivalents as fall within the true spirit and scope of the present invention.
