BACKGROUND
Aircraft instrument panels are largely composed of instruments dedicated to a single purpose, such as displaying a single piece of information or receiving a specific type of control input from a user. These instruments typically include gauges, dials, buttons, switches, text or graphic display monitors, and other similar components. As a result of their single purpose and physical arrangement, the instrument panel has limited flexibility and customizability. The instruments are in fixed locations and are limited in what information they can display or input they can receive from the user.
Also, since typically an aircraft must provide functionality for both a pilot and a co-pilot, the instrument panel includes duplicate instruments to provide for two users. This reduces the effective area of the instrument panel available for the display of information.
A flexible, customizable instrument panel, utilizing touch screen technology and providing a user friendly, intuitive interface for receiving information and controlling the aircraft are described. A user interface that provides a synoptic, summary overview of the aircraft configuration and operation is also described.

DETAILED DESCRIPTION
Embodiments of the present invention provide a touch-screen interface panel (TSIP) in a cockpit of an aircraft.
Referring to FIG. 1, a representation 100 of a touch-screen instrument panel (TSIP) is illustrated. The TSIP replaces the plurality of instruments, dials, gauges, and screens typically utilized on the console of an aircraft. The TSIP is configured for at least a touch screen implementation. In some embodiments, the TSIP may span the width of a cockpit of an aircraft. As illustrated in FIG. 1, the TSIP is the width of the cockpit and may be accessed by both a pilot, co-pilot, and the like.
The TSIP is a digital information panel and may include a plurality of digital layers. The digital layers may overlay one another to create multiple views. For instance, and as will be described in further detail below, one layer may be a real-time view while another layer may be a three-dimensional representation of, for example, weather while another layer may include flight instruments and may not be obstructed with any other layers or representations. A processor, similar to that onboard computer 201 of FIG. 2, for example, may stack the plurality of digital images to provide a complete real-time image including the real-time view and any other additional information stacked on top of it as deemed appropriate by the user. Additional information may include synthetic vision, three-dimensional weather, information regarding traffic or airports, etc. Furthermore, the TSIP may be configured such that, in the event of a failure or malfunction of the TSIP, each digital layer is cleared so that the flight instruments are accessible/viewable to users.

In an embodiment, computer 201 includes a first computer and a second computer located on-board the aircraft, where the second computer mirrors the first computer, thereby providing redundancy in the event of a computer failure. It should be recognized that where a single computing device (e.g., computer 201) is represented graphically, the component might be represented by multiple computing units in a networked system or have some other equivalent arrangement which will be evident to one skilled in the art.
TSIP 210 provides a user interface for visualizing and controlling subsystems of system environment 200 through computer 201. TSIP 210 includes a substrate that supports a display and a touch membrane. Substrate is a transparent material such as glass, acrylic, polycarbonate or other approved for flight materials on which display and touch membrane are overlaid. In an embodiment, substrate is made of flexible material for conforming to aircraft cockpit dimensions, including complex shapes such as corners. In an embodiment, substrate has a large aspect ratio for providing images. Display is for example an organic light-emitting diode (OLED) display, which is thin and flexible for layering onto substrate. When unpowered, the display is, in embodiments, transparent. Touch membrane is a thin, transparent and flexible material that is layered onto display and capable of sensing touch. Touch membrane is for example a resistive, capacitive, optical, or infrared touch screen. Together, touch membrane and display provide TSIP 210 with a visual display that a user may control by touching with one or more fingers or a stylus.
Local digital network 220 provides a digital connection between computer 201 and on-board subsystems, such as cabin management subsystem (CMS) and in-flight entertainment (IFE). CMS includes for example cabin lighting, heating, air conditioning, water temperature, and movement of shades. IFE includes for example audio and video content. TSIP 210 provides an interface for monitoring and controlling CMS and IFE over local digital network 220.
Databases 230 are digital databases stored in memory of computer 201 on-board the aircraft. Databases 230 include charts, manuals, historical aircraft component data, and checklists. Databases 230 allow pilots to quickly access and search information via computer 201. TSIP 210 displays the information such that pilots maintain a heads-up view while piloting an aircraft. Historical aircraft component data is for example updated during flight with data from aircraft flight equipment 250 (e.g., sensors) via computer 201.
Flight controller 240 provides navigation, avionics, and autopilot functions. In an embodiment, flight controller 240 is a standalone unit supplied by an independent manufacturer (e.g., Garmin, Honeywell, Rockwell Collins). TSIP 210 displays aircraft information from flight controller 240 via computer 201 such as airspeed, altitude, heading, yaw, and attitude (i.e., pitch and bank).
Aircraft flight equipment 250 includes flight control surfaces, engines, deicing equipment, lights, and sensors (e.g., temperature, pressure, electrical). Aircraft flight equipment 250 is monitored and controlled by pilots using TSIP 210 through computer 201 for flying aircraft.
Communications equipment 260 allows pilots to communicate with one another, with passengers, and with airports and other aircraft. Communications equipment 260 includes radios, phones, and internal and external digital networks (e.g., Internet and Intranet). Different frequency bands are used for example to transmit and receive data with multiple recipients. TSIP 210 allows pilots to communicate with others by using communications equipment 260 via computer 201.
Communications equipment 260 includes a transceiver configured to communicate with external communication sources 265, which include for example terrestrial based communication towers, satellites, and other aircraft. External communication sources 265 also provide communications with for example radio, global positioning system (GPS), and Internet. TSIP 210 provides a user interface for communicating with external communication sources 265, enabling a pilot or co-pilot to communicate with air traffic control, terrestrial communication towers (e.g., navigation towers, waypoints), satellites, and directly with other aircraft for example. TSIP 210 allows pilots to receive and transmit external communications through communications equipment 260 and computer 201.
Satellites provide network links for phone and Internet communications, and GPS information. Aircraft interact with satellites using communications equipment 260 to transmit and receive radio frequency signals. TSIP 210 allows pilots to communicate via satellites through computer 201 and communications equipment 260.
Other aircraft within view of camera 290 are displayed in real-time on a panoramic view provided by TSIP 210. Information about other aircraft, which may be retrieved from radar 270 or radio communication, is displayed for improved pilot awareness and ease of contact.
Radar 270 includes equipment for determining a location and speed of objects from radio waves. Equipment for radar 270 includes a radio transmitter for producing pulses of radio waves and an antenna for receiving a reflected portion of the radio waves from nearby objects. TSIP 210 receives information from radar 270 via computer 201 and uses the information to display the location of nearby objects, such as weather, terrain and other aircraft.
Anti-collision and terrain awareness 280 includes a traffic collision avoidance subsystem (TCAS) and a terrain awareness and warning subsystem (TAWS). Anti-collision and terrain awareness 280 includes radar 270 and transponder information to determine aircraft position relative to other aircraft and Earth terrain, and to provide appropriate warning signals. TSIP 210 displays these warnings and allows pilots to respond to them by, for example, silencing an audible warning signal.
Camera 290 provides forward looking images to TSIP 210 through computer 201. Camera 290 is mounted for example under the aircraft nose. In alternative embodiments, camera 290 is located on the tail or on aircraft wings. Camera 290, in embodiments, receives one or both of visible light as well as infrared (IR) light. Further, in embodiments, camera 290 provides high-definition (HD) quality images (e.g., using an HD capable camera). In a preferred embodiment, camera 290 provides HD quality and IR functionality. Alternatively, camera 290 might include two separate cameras, one for HD quality and a second camera for IR imaging.
Camera 290 provides images to computer 201, which renders the images for real-time projection on TSIP 210. TSIP 210 projects HD panoramic views looking forward and below from the front of the aircraft. The forward view spans an angle of about 120° to about 180° for example. In an embodiment, TSIP 210 uses IR imaging to project a synthetic view, which is for example useful at night or when flying through clouds or fog that obscure visible light.
Various components of the user interface displayed on TSIP 210 are designed to provide a synoptic view of the condition of the aircraft, meaning that the user interface components provide an intuitive, broad view of the aircraft, its various components and subsystems, and their condition. The user interface utilizes the touch screen functionality of the TSIP 210 to present views of the aircraft to intuitively communicate information and accept input from the pilot. The views of the aircraft incorporate graphical, textual, and numerical elements to simultaneously convey multiple pieces of information to the pilot. The graphical, textual, and numerical elements of the user interface may flash, change color, change content, appear, disappear, move or change location, or otherwise change in response to user input or the state of the aircraft systems.
The computer 201 monitors the aircraft's data busses to determine the positions, temperatures, pressures, and states of various equipment and systems of the aircraft. TSIP 210 graphically displays the data gleaned from the busses and stored in computer 201 in the appropriate synoptic panels or windows for flight crew interaction. The inventive user interface provides a thorough, easily understood, intuitive and user-friendly interaction with each synoptic user interface. The touch screen functionality of TSIP 210 also allows the user to activate aircraft systems and change configuration settings through user interface displayed on TSIP 210.
The user interface may provide a variety of user interface elements grouped into a variety of “windows”, which may also be referred to as “panels” or “pages. Some user interface elements are common to a plurality of the synoptic user interface panels. For example, each user interface panel may comprise a border surrounding the information displayed in the user interface and defining a “panel”. A title for each user interface may be displayed within the panel or on the border of the panel area. In some embodiments, the title is displayed in the top or the bottom left or right corner of the panel. The title may optionally be displayed as an abbreviation. Similar to other known graphical user interfaces, each “window” or “panel” may be provided with controls for closing or minimizing the panel to remove it from active display on TSIP 210. Various embodiments of the panels that are presented in TSIP 210 are described in relation to FIGS. 4A through 4E and FIGS. 4G through 4K.
In some embodiments of the user interface, a silhouette, cross-section, or other diagram of an aircraft is utilized to illustrate the state of the aircraft and convey relevant information to the pilot. The diagram of an aircraft may be a top, bottom, side, front, back, or perspective view of an aircraft. The windows may incorporate both static elements and active controls. Static elements comprise elements that are fixed or are updated automatically by the system to display the current aircraft configuration. Active controls may be updated automatically by the system to display the current aircraft configuration, but are also capable of interacting with the user via TSIP 210 to receive pilot input.

FIG. 3K depicts an embodiment of a synoptic user interface panel for aircraft cabin window shades. In some embodiments of this user interface, a top view 377 of an aircraft is depicted. The top view 377 allows a user to select which side of the aircraft cabin will be displayed in the user interface by touching the appropriate side of top view 377. Additionally, the color of a portion of the top view 377 may change to indicate which side of the cabin is currently depicted below. In other embodiments of this user interface, top view 377 may not be present and both sides of the aircraft cabin may be depicted simultaneously. The side view 378 of a portion of the aircraft cabin depicts each window 379 in the cabin and may also show other features of the cabin interior such as seats 380. The color of each window 379 may be modified to show the state of the shade at each window. For example, an open shade may be represented by a white window 379, while a closed shade may be represented by a black window 379. In some embodiments, an interface panel may be provided for raising, lowering, activating, and deactivating cabin video and audio displays, and selecting and displaying video and audio content on such cabin displays.
In some embodiments, an additional status ring 381 may be provided around each window 379. The color of the status ring 381 may provide additional information regarding the status of the window. A user may individually raise and lower a window shade by touching the window 379. In some embodiments, additional buttons 382 and 383 may be provided to allow a user to open or close, respectively, all shades simultaneously.
In other embodiments, the TSIP 210 may provide access to control additional types of cabin or aircraft functions, or provide additional information to the users. The user interfaces described herein are not limiting but exemplary of the types of synoptic user interfaces contemplated within the inventive system.
In some embodiments of the system, the various windows may be opened, closed, and moved around the TSIP 210. A user may “drag” or move the window by touching the window in a certain area and moving a finger across the TSIP 210 while maintaining contact with the TSIP 210. In some embodiments, once the finger is lifted from the TSIP 210 the window stops moving, though in other embodiments the window may have emulated momentum to continue moving for some additional distance if the finger is moving when lifted from the TSIP 210. In various embodiments, the areas that a user may touch to drag the window or page may include the title bar (if present), the border (if present), or any portion of the window that does not comprise an active control such as a button.
In some embodiments, the windows may overlap or overlay one another to allow the user to maximize the use and efficiency of the TSIP 210. A user may bring a window to the foreground by touching the window, and may move it in front of another window by dragging it to a location that wholly or partially overlaps another window shown on the TSIP 210. In some embodiments, a user must bring a window to the foreground position on the TSIP 210 before activating an active control located in the window.
In some embodiments the system does not allow a user to move windows into certain areas of the TSIP 210, such as areas that display primary flight controls or other information that must be visible for the safe operation of the aircraft. In some embodiments for a single pilot application, the pilot could open multiple synoptic pages or windows and arrange them on the co-pilot Multi-Function Display (MFD) area of the TSIP 210. The flight crew may open multiple synoptic pages or windows and arrange them by physically moving them on the TSIP 210 as they see fit to help maintain a higher state of situational awareness.
In some embodiments of the user interfaces, a user may need to fix a user interface panel in a certain place on the TSIP 210. This may be necessary to prevent accidental movement of user interface panels, or because some user interface panels may be completely covered with an active control such as a map that cannot be activated when the window is capable of being dragged across the TSIP 210. In those embodiments, the user is provided with a method of “pinning” a user interface panel in place on TSIP 210 such that the user interface panel is not movable from its current location on the screen until it has been “unpinned”.
Referring now to FIGS. 3L and 3M, a user interface panel is depicted with an embodiment of the pinning functionality. In this example, a mapping or weather function is displayed in the panel 390. At some times the user may want to move the panel 390 to a desired location on the TSIP 210, while at other times the user may want to alter the contents of the panel 390 to display different portions of a map within panel 390. The touch input required for both changes may be the same, for example, touching the TSIP 210 and dragging a finger across the panel 390. The panel 390 is provided with a pin icon 391 which may be touched by a user to toggle the pin function on and off.
In FIG. 3L, the pin icon 391 is not highlighted and the pin function is inactive. When the user touches the screen within the panel 390 and moves a finger, the entire panel 390 will move on the TSIP 210. The contents of the panel 390 will not change as the panel 390 moves across the TSIP 210 in response to the users touch input. When the user has moved the panel 390 to the desired location, the pin icon 391 is touched to activate the pin function and prevent further movement of the panel 390 on the TSIP 210.
In FIG. 3M, the pin icon is highlighted as a result of the users touch input. As the user touches the TSIP 210 within the area of panel 390, and drags a finger across the screen of the TSIP 210, the content of the panel 390 changes in response to that movement. For example, the user may pan a map within the panel 390 by dragging a finger within panel 390, or pinch two fingers together on the screen to zoom in on the content. When a user desires to move the panel 390 to a different location on the TSIP 210 they touch the pin icon 391 to deactivate the pin function, and then the panel 390 will move on TSIP 210.
FIGS. 4A-4E depict exemplary panels of a flight planning system for navigation of an aircraft. The flight planning system is displayed on TSIP 210, which uses on-board computer 201 for storing and executing instructions. Algorithms written with software calculate flight planning information, such as flight duration for example, using computer 201.
On-board computer 201 includes a manager for providing navigational views on TSIP 210. The navigational views on TSIP 210 include a mapping interface for displaying one or more maps (see FIGS. 4A-4E), a charts component for displaying one or more aeronautical charts (see FIGS. 4G-4J), a radio frequency component for receiving and displaying one or more radio frequencies (see FIG. 4K), a weather component for displaying one or more weather representations overlaid on the map (see FIGS. 4A-4E), and a virtual flight plan component for displaying one or more simulated flight plans.
FIG. 4A depicts an exemplary panel 400 of the flight planning system. Panel 400 is configured to show a mapping interface 429 based on high instrument flight rules (IFR). Mapping interface 429 includes a displayed image of a map, which may be manipulated by a user with touch gestures, such as zooming and dragging, to view maps of various areas of Earth. Panel 400 includes menus listed, for example, along the bottom, top and sides of the panel. The menus may include icons, names or abbreviations that may be activated by touch, thus serving as links or shortcuts to various features of the flight planning system. The menu along the bottom of panel 400 includes, for example, a title indicator 401, a proximity icon 402, a favorites icon 403, a weather link (WX) 404, a skytrack link 405, a waypoints link 406, a procedures link 407, a direct-to link 408, and a standby-plan link 409. Panel 400 may be configured to display greater or fewer menu items along the bottom or to arrange items differently without departing from the scope hereof.
Proximity icon 402 may be configured such that selection thereof activates a proximity component of the flight planning system for organizing information based on distances from the aircraft. For example, activating the proximity component by selecting proximity icon 402 displays a list of nearby airports and their corresponding radio frequencies on TSIP 210, wherein the list is organized by proximity to the aircraft. Information is updated real-time during aircraft flight, thereby re-organizing the list as needed to continually provide information for the nearest airports. Proximity icon 402 provides a convenient one-touch link to display information for flight planning based on proximity. Proximity may be defined as any distance relative to the aircraft within a predetermined maximum distance.
Favorites icon 403 is configured such that selection thereof activates a favorites component of the flight planning system for organizing information based on a custom list of favorite items. For example, activating the favorites component by selecting favorites icon 403 displays a list of frequently used or favorite items on TSIP 210, wherein the list may be tailored to individual pilot preference. The list of favorite items may include flight paths and airports with their corresponding radio frequencies, for example. Favorites icon 403 provides a convenient one-touch link to display information for flight planning based on a custom list.

Based on flight path 421 displayed in mapping interface 429, distance indicator 414 may display a value, for example, in nautical miles (NM) and duration indicator 415 may display a value, for example, in hours and minutes (hh:mm). Distance indicator 414 is 162.14 nautical miles and duration indicator 415 is 52 minutes, as shown in FIG. 4A. As alternate flight paths are considered, distance indicator 414 may display corresponding alternate distances and duration indicator 415 may display corresponding alternate times. During flight, as the distance and duration remaining to arrive at the destination decrease, the distance indicator 414 and duration indicator 415 update accordingly. For flight planning activities, distance indicator 414 and duration indicator 415 conveniently display the remaining estimated flight path distance and duration, respectively.
Altitude indicator 416 is configured such that selection thereof activates an altitude component of the flight planning system. Similarly, airspeed indicator 417 is configured such that selection thereof activates an airspeed component of the flight planning system.

Embodiments of the present invention are directed to providing navigational aids. Navigational aids have been used in aircraft to assist users in navigation and to improve situational awareness. However, the aids are typically separate components and sometimes multiple sources need to be referenced to gain access to necessary information. Additionally, the displays of previous navigational aid systems were limited and not able to display detailed information related to the navigational aid. For example, the previous displays were typically very small so including detailed information was not feasible since there was no room on the screen to display the information.
A navigational aid, as used herein, refers generally to a tool utilized to aid in the navigation of a vehicle whether it is the physical navigation of the vehicle, additional information aiding in the physical navigation of the vehicle, or the like. A vehicle may be any mode of transportation including, but not limited to, aircraft, watercrafts, etc. In preferred embodiments, the present invention is implemented within an aircraft. While navigational aids currently exist that help “guide” a vehicle, or aircraft in embodiments, that is the extent of the aid. A mere “guide” showing where the aircraft is traveling is provided. The present invention offers integration of multiple informational sources as well as detailed navigational information.
The navigational aids of the present invention may be displayed via the TSIP 210. Additionally, the use of a camera, such as camera 290, may facilitate the capture of the real-time image displayed on the TSIP 210. The navigations aids described herein may be displayed on the TSIP 210 overlaying the real-time image. In embodiments, navigational aids are displayed overlaying a three-dimensional real-time panoramic view. The navigational aids may include, for instance, a flight guide, an airport guide, and a traffic guide, to name a few. Any other application that aids in the navigation of a vehicle (e.g., aircraft) may be included in the navigational aids displayed via TSIP 210.
Initially, a flight guide navigational aid will be discussed. The flight guide may be displayed overlaying the three-dimensional real-time image of the TSIP 210. The flight guide itself may be displayed in a three-dimensional representation. The flight guide, with the use of a plurality of planes, or path indicators, creates a graphical representation of a flight plan and/or flight path. Flight plan, as used herein, refers generally to a planned path identified at the onset of the flight an aircraft should follow to arrive at a destination. A flight path, as used herein, refers generally to an actual path of an aircraft. The flight path may or may not be the same as the flight plan. User configurations may determine whether a flight plan or flight path is displayed. Alternatively, a setting could be selected that provides both the flight plan and the flight path such that a user is able to quickly view if there are any differences between the current flight plan and the planned flight plan.
The flight guide may interact with various systems of an aircraft including, but not limited to, aircraft avionics, autopilot and flight plan systems to determine location, speed, altitude, attitude, and the like, to display the appropriate flight track the aircraft will/should follow. The information necessary to the flight guide application may be acquired from the ARINC Data Bus of any avionics manufacturer system. In embodiments, the flight guide application may be a stand-alone component in communication with the avionics manufacturer's system. In additional embodiments, the flight guide application may be incorporated into an avionics manufacturer's system.
FIG. 5A provides an exemplary graphical user interface (GUI) 501 illustrating a flight guide application. A real-time image 502 is provided via the TSIP 210 and the flight guide application is provided such that it is overlaying the real-time image 502. The flight guide application is embodied in GUI 300 as a flight path 503 comprising a plurality of planes, or path indicators. The plurality of planes/path indicators may be used to highlight the flight path 503 of an aircraft. The plurality of planes may each be associated with various coordinates (e.g., physical locations in space), glide slopes, and the like. In an embodiment, the information associated with each plane/path indicator (e.g., glide slope, etc.) is displayed to a user upon an indication such as selection of the plane, hovering over the plane/path indicator, etc.
The flight guide application may be a feature that is controlled directly from the TSIP 210. FIG. 5B provides an exemplary GUI 505 illustrating the selection features of the flight guide application. The flight guide 506 may be displayed in combination with a menu including a flight guide activation icon 507 and a user interface panel 508 including flight path details. The flight guide activation icon 507 may be configured such that selection thereof provides a detailed flight plan user interface panel 508. The user interface panel 508 may include the flight plan from origin to destination, weather, a current flight path to destination, and the like. Within the user interface panel 508 a flight guide activation icon 509 may be included that is configured such that selection thereof activates (i.e., turns on) or deactivates (i.e., turns off) the flight guide application. If deactivated, the flight guide 506 may no longer be presented on the TSIP 210. Upon reactivation, the flight guide 506 may reappear via the GUI 505. This allows users the ability to dynamically control activation of the flight guide 506.
Turning now to FIG. 5C, an exemplary GUI 510 is provided that illustrates a flight guide 511. As previously mentioned, the flight guide 511 illustrates a flight path including one or more path indicators to provide a graphical representation of the flight path. The one or more path indicators may each be associated with spatial coordinates. For instance, a first path indicator 512 is associated with different spatial coordinates than a second path indicator 513. Additionally, each of the path indicators may be represented in a different manner as the vehicle is approaching a path indicator. For example, the representation may be based on distance such that a first path indicator within X distance may be represented one way (e.g., a specific color, a visual representation, etc.) while a second path indicator within Y distance (further than X distance) may be represented another way, different from the first path indicator (e.g., a specific color different than that used for the first path indicator, a visual representation different from that used for the first path indicator, etc.). Alternatively, path indicators may be displayed the same way when they are each greater than a predetermined distance from the aircraft. This may be helpful so that only path indicators that are proximate (within a predetermined distance from an aircraft) are displayed differently and attract attention while the remaining path indicators that are not proximate indicate the flight path without distinguishing representations.
A plurality of path indicators is provided in FIG. 5C and may be seen as a first path indicator 512 and a second path indicator 513. As is shown, first path indicator 512 is on top of, or before, second path indicator 513 in the flight guide 511. This alerts users that the first path indicator 512 and coordinates associated therewith will be encountered prior to the second path indicator 513 and its respective coordinates.
The flight guide 511 may include one or more waypoints. A waypoint, as used herein, refers generally to coordinate in physical space. FIG. 5C provides a first waypoint 5314 and a second waypoint 515. By of example, a waypoint may be a destination airport, radio beacon, or VOR (VHF Omni-Directional Radio) stations along the flight guide, etc. The flight guide 511 may be configured so that path indicators are associated with waypoints. In embodiments, path indicators are displayed differently when approaching a waypoint. For example, when an aircraft is proximate to a waypoint (i.e., within a predetermined distance from a waypoint), the path indicators leading to the waypoint may be displayed differently to signal an approach. The path indicators may, for example, flash when the aircraft is approaching the path indicator. The path indicators may, alternatively, change colors to signal a relative distance from the aircraft, the waypoint, etc. The information necessary to integrate the flight guide, waypoints, etc., may be acquired from any aircraft system previously mentioned that typically supplies the data (e.g., GPS, charts, etc.).
This example is further described with respect to FIG. 5D. FIG. 5D provides an exemplary GUI 516 that is a front-view of a flight guide 517 including one or more path indicators, a first path indicator 518 and a second path indicator 519. As with FIG. 5C, the first path indicator 508 and second path indicator 519 are arranged such that the path of the aircraft is apparent to one or more users.
FIG. 5E provides an exemplary GUI 520 of an exemplary descent screen. As in FIG. 5C, a flight guide 521 is provided with one or more path indicators illustrated. The concept described with reference to FIG. 5C is applicable in this example as well but is directed to a descent, specifically. As previously described, the one or more path indicators may be configured to convey information based on a distance to or from a waypoint, the aircraft, or the like. In a descent situation, the one or more path indicators proximate to the destination will indicate a descent is approaching and may be proximate to a waypoint 522 (e.g., destination airport). Similar to previous examples, this may be illustrated by displaying the path indicators differently to draw attention to them by, for example, using different colors, flashing the path indicators, etc. It is noted that the flight guides provided in FIGS. 5A-5E are overlaying a three-dimensional real-time image on the TSIP.
One or more airports, as previously described, may be provided in a flight guide as a waypoint, a destination, an origin, or the like. When navigating, it may be useful to have access to airport information associated with said airports, whether it is the destination airport or not, for a variety of reasons. FIG. 5F provides an exemplary GUI 523 illustrating an embodiment where detailed information regarding an airport is provided. As with the previous GUI's described, FIG. 5F depicts a flight guide overlaying a real-time image. FIG. 5F provides a destination airport indicator 524 along with a user interface panel 525. The destination airport indicator 524 may be configured such that selection thereof results in the display of the user interface panel 525. A selection may be hovering over the indicator 525, touching the indicator 525 with a finger, a stylus, or any other input device, or any other method used for selection of an item on a touch-screen interface. The user interface panel 525 may include detailed information associated with the indicator 524. In this case, the destination airport indicator 810 is associated with a destination airport so information related to the particular destination is provided such as, for example, the airport code of the airport, an elevation, a distance of the destination airport from the aircraft, a frequency with which to contact the airport, and the like. Any information may be provided in the user interface panel 525 as determined by a user.
Airports may be presented within the TSIP when it is determined they are within a predetermined distance from the aircraft. The predetermined distance may be any distance desired by a user and is configurable such that it may be dynamically changed. An exemplary predetermined distance is 150 nautical miles. A current location of the aircraft may be continuously monitored such that the predetermined distance evaluated is constantly changing. For instance 150 nautical miles from the aircraft at Point A is different when the aircraft travels 5 miles east to Point B. Thus, the TSIP may be in constant communication with other aircraft systems to provide updated, real-time data including a current location of the aircraft and any updates to airport information based on changes in the aircraft's current location.
As with airports, there may be situations where detailed information related to traffic may be needed. Traffic, as used herein, refers generally to any vehicle proximate to, or within a predetermined distance of, the aircraft. FIG. 5G provides an exemplary GUI 526 illustrating a traffic embodiment of the present invention. FIG. 5G illustrates this embodiment where traffic is indicated with a flight instrument display (similar to flight instrument display 120 of FIG. 1) but traffic could be displayed in any part of the TSIP. Here, an item of traffic is detected and represented as traffic icon 527. Traffic icon 527 may be associated with a traffic information panel 528. The traffic information panel 528 may include a tail number as a traffic identifier or any other identifying means to identify traffic associated with the traffic icon 527. In this case, a tail number of the aircraft associated with the traffic icon 527 is provided in the traffic information panel 528.
Traffic icon 527 may be configured such that selection thereof may result in a display of detailed traffic information. The detailed information may be provided in a detailed traffic panel as illustrated in FIG. 5H. FIG. 5H provides an exemplary GUI 529 illustrating a traffic icon 530 and a detailed traffic panel 531. The detailed traffic panel 531 in this case provides a tail number as a traffic identifier or other identifying means (that may have been displayed in a traffic information panel similar to traffic information panel 528 of FIG. 5G prior to selection of the traffic icon 530) as well as an elevation of the traffic associated with the traffic icon 530, a distance away from the aircraft, a speed, and the like. Information displayed may be configured by users to achieve a customized interface.
The ability to make a selection of, for example, a traffic icon or a destination airport indicator allows users to obtain a real-time detailed view via the TSIP where users may have otherwise been required to reference several sources to compile information and still would not have the compilation viewable on a touch screen interface with a single selection. Each embodiment of this application (e.g., traffic and airport details, flight guides, etc.) may be provided overlaying a real-time image.
Additionally, with each of the airport and traffic embodiments, information may have been previously displayed such as a simple identifier but detailed information including distance, elevation, speed, etc. was not previously displayed.
Furthermore, with each of the airport and traffic embodiments, a current location of the aircraft is continuously monitored and updated (via, for example, GPS) such that the airport information, traffic information, waypoint information, etc. is accurate. For example, the flight guide discussed herein is configured to indicate a proximate waypoint. A current location of an aircraft is continuously monitored and updated so that it is known when a waypoint is within a predetermined distance of the aircraft. Similarly, a current location of an aircraft should be known at all times in order to ascertain traffic that is within a predetermined distance of the current location. This real-time monitoring provides up-to-date information. Furthermore, detailed information provided (e.g., detailed airport information, detailed traffic information) may include information that requires updating based on updates to a current location of an aircraft. For instance, in FIG. 5H, a distance from the aircraft is provided as 4.1. As the aircraft moves, and as the traffic moves, this distance between the two changes and may be updated as updated locations and speeds are identified of both the aircraft and the traffic.
Traffic information may be provided to users based on distance levels. A distance level, as used herein, refers generally to distance ranges to organize data. Aircraft users (e.g., pilots, co-pilots) would like to be alerted to traffic but, in some cases, may not need an urgent alert. For example, traffic may be detected that is X distance away from aircraft, where X is a completely normal, safe distance. On the other hand, traffic may be detected that is Y distance from the aircraft, where Y is not necessarily a risk yet but is something that should be monitored or may require action. Lastly, there may situations where traffic is detected at Z distance, where Z is an emergent situation that is a risk and requires action to avoid danger. It makes sense to provide these varying levels of traffic notifications to a user in a different manner. Thus, distance levels may be utilized to organize traffic. Distance levels may be configured by a user and exemplary figures are only used herein for example purposes only. Assume that a predetermined distance from an aircraft to monitor is 100 nautical miles. A first distance level may be 50-75 nautical miles, while a second distance may be 25-50 nautical miles, and further more a third distance may be less than 25 nautical miles. Again, these distances are merely exemplary and may be configured and customized for each user's preferences. Additionally, the system may be configured to include as many distance levels as desired by users.
Thus, when traffic is detected within the first distance level, it may simply be displayed via the TSIP with some identifying information. Alternatively, traffic at other distance levels designated by a user to accompany a notification may be provided via the TSIP along with an alert. The alert may be a separate notification (e.g., a pop-up alert panel) or may be included in or with the traffic icon (e.g., an exclamation point on the traffic icon, the traffic icon appearing in an alert color (e.g., red), and the like). Additionally, the TSIP may be equipped with a master alert system that results in the TSIP (the entire TSIP) indicating an alert is present. In the example of nearby traffic, if an alert is warranted based on the distance level, the TSIP master alert system may initiate and generate an alert by, for example, making a border of the TSIP flash with an alert (e.g., the border may flash a color (red)), switch to an alert state (e.g., the border may switch to an alert color designated by a user), or the like.
With reference to FIG. 5I, a flow diagram is provided showing an exemplary method 532 for providing navigational aids. Initially, at block 533, an indication of a flight path that includes one or more waypoints is received. A graphical representation of the flight path is generated at block 534. The graphical representation includes a plurality of planes (path indicators) along the flight path, wherein each plane is associated with a slope and an angle for an orientation of a vehicle navigating the flight path. At block 535 the graphical representation is dynamically updated relative to an updated location of the vehicle.
With reference to FIG. 5J, a flow diagram is provided showing another exemplary method 536 for providing navigational aids. Initially, at block 537, one or more airports proximate to a location of an aircraft is identified. Information associated with the one or more airports is identified at block 538 and includes, at least, an airport identifier and a distance from the aircraft. An airport icon is generated for each of the one or more airports at block 539 and is provided at block 540. At block 541, the one or more airports and airport icons are updated based on an updated location of the aircraft.
With reference to FIG. 5K, a flow diagram is provided showing yet another exemplary method 542 for providing navigational aids. Initially, at block 543, a location of a first aircraft is identified. At block 544, any traffic within a predetermined distance of the first aircraft is identified, wherein traffic includes other aircraft. It is then determined that a second aircraft is within the predetermined distance of the first aircraft at block 545. A traffic user interface panel that includes information associated with the second aircraft including airspeed of the second aircraft is generated at block 546. The predetermine distance from the first aircraft is monitored and updated according to an updated location of the first aircraft at block 547.
Additional embodiments of the present invention are directed to providing a synthetic vision display in combination with the TSIP. SVS have been used in aircraft for quite some time to improve situational awareness. However, the synthetic vision enhancements were either applied entirely or not at all. SVS are not currently available in a gradient-type application. In other words, synthetic vision enhancements have not been applied to a real-time image to achieve an image that is a combination of a real-time image and a synthetic vision enhancement. For example, rather than turning the SVS on and viewing a 100% synthetic image, a user could, utilizing the present invention, indicate that a synthetic vision enhancement should be applied according to a synthetic vision application value. A synthetic vision application value, as used herein, refers generally to a numerical value with which to apply a synthetic vision enhancement. In embodiments, the synthetic vision application value is a percentage value. In additional embodiments, the synthetic vision application value is a percentage value less than 100% to achieve a combination of a synthetically enhanced image and the real-time original image.
In application, a real-time image is captured by, for example, the camera 290 of FIG. 2, and displayed via the TSIP 210. The real-time, unenhanced, image may be referred to as an original image herein. FIG. 6A illustrates an exemplary graphical user interface (GUI) 601 in which a real-time image is displayed. The GUI includes, as previously identified, one or more flight instrument displays 602, one or more navigational displays 603 and the underlying real-time image 604. As is shown in FIG. 6A, the real-time image 604 does not include much detail as visibility is low in this example. Thus, one could imagine the view of the real-time image 604 as it is displayed is merely fog, clouds, etc.
The original image may be modified to include synthetic vision enhancements upon receiving an indication to apply a synthetic vision application or enhancement to the original image. The indication may be a user selection from a menu of the TSIP or any other means available to activate or apply a synthetic vision enhancement.
Once indicated, a synthetic vision application value is identified and applied to an original image. The synthetic vision application value may be user input. Alternatively, a default value may be set in the system to be automatically applied such as, for example, 50%. Any desired value may be set as the default value.
The indicated synthetic vision enhancement may be overlaid on the original image to generate a modified image. FIG. 6B illustrates an exemplary GUI 605 in which an original image is modified, or overlaid, with a synthetic vision enhancement according to a synthetic vision application value. FIG. 6B includes a modified image including a synthetic vision enhancement at a 50% application value. As is clear in FIG. 6B, the GUI 605 includes a view area 606 that is much clearer and more detailed than that in FIG. 6A. Note that the images in FIG. 6A and FIG. 6B are identical and are only different in the amount of synthetic vision applied to illustrate the clarity achieved with the gradient functionality of the synthetic vision application of the present invention. FIG. 6B clearly identifies various parts of a landscape including terrain 607, water 608, and clouds 609. The markers identified in FIG. 6B (i.e., terrain, water, clouds) are merely exemplary in nature and any identifying markers could be included in a view.
FIG. 6C goes on to include a detailed GUI 610 in which the original image is modified, or overlaid, with a synthetic vision enhancement according to a synthetic vision application value. FIG. 6C includes a modified image including a synthetic vision enhancement at a 90% application value. The application values illustrated in FIGS. 6A, 6B, and 6C are merely exemplary in nature and any value from 0-100% is possible. Ideally, a value less than 100% is utilized to achieve an image combining both a synthetic, digitally created view with a real-time, original view. Also, as with FIG. 6B, the image of FIG. 6C is identical to that of FIG. 6A, it is merely illustrating the original image of FIG. 6A overlaid with a synthetic enhancement. As is shown in FIG. 6C, the view area 606 includes the landscape shown in FIG. 6B, but with a higher degree of clarity. For instance, more details are visible in terrain 611 and clouds 613. Also present is water 612.
The gradient-type feature of the synthetic vision application provides users the ability to dynamically adjust images. This improves situational awareness by allowing users more power in controlling the image. For example, on a foggy/cloudy day, a user may need more synthetic vision to “see” through the weather but as the fog/clouds lift, the user could reduce the amount of synthetic vision enhancements to bring in real images to better identify landmarks (e.g., roads, rivers, houses, etc.) that the synthetic vision would not show.
The TSIP 210 may be further configured to display data in a three-dimensional view. Weather, for instance, may be displayed in a three-dimensional view in combination with the original image. Alternatively, data (e.g., weather) may be displayed in a three-dimensional view in combination with a modified image including the original image and a synthetic vision enhancement. This embodiment is illustrated in FIG. 6D where a GUI 614 is provided that illustrates a modified view with a synthetic vision enhancement (note distinction in the view from FIG. 6A) and also including a three-dimensional weather representation 615. Previously, this combination presentation was not achieved since SVS data was typically presented on such a small display and overlaying any information could render the synthetic vision image useless (e.g., too much information in the small screen could overload or confuse the user). In the present invention, the TSIP 110 provides such an expansive view that many data points can be overlaid, including weather and synthetic vision, without overloading or confusing an image or a user. Furthermore, the ability to control the synthetic vision application value allows users to scale back the synthetic vision application when appropriate so that other items such as weather, for instance, may be highlighted when necessary.
Furthermore, two-dimensional user interface panels may be provided at any view of the TSIP. For instance, user interface panels may be provided over an original image, a modified image including an original image and a synthetic vision enhancement, or a modified image including an original image, a synthetic vision enhancement, and a three-dimensional representation. FIG. 6E provides a GUI 616 illustrating an embodiment where a two-dimensional user interface panel 617 is provided over a modified image (e.g., an original image overlaid with a synthetic vision enhancement) including a three-dimensional representation 618 (e.g., weather). In the illustration of FIG. 6E, the three-dimensional representation 618 is weather. Additionally, the two-dimensional user interface panel 617 is a weather user interface panel but could be any other panel configured by the system. The two-dimensional user interface panel 617 may be moved to any portion of the TSIP 210 or may be closed by selection of indicator 619. Additionally, the user interface panel 617 may be pinned to the TSIP such that is may be manipulated with user gestures within the user interface panel 617. For instance, the user interface panel 617 itself may be pinned to the TSIP such that the user interface panel 617 is stationary. Then a user could manipulate the user interface panel 617 via one or more gestures such as, for example, scrolling within the user interface panel 617, zooming in or zooming out the user interface panel 617 view via gestures, and the like.
In application, a second modified image may be generated upon receiving an indication that weather information (whether two or three-dimensional) is to be included in an image. The second modified image may be a modified image that includes the original image and a synthetic vision enhancement combined with weather information. Alternatively, weather information may be overlaid with an original image. For instance, an original image could be modified to include three-dimensional weather representations without the addition of any synthetic vision enhancements.
While various data points (e.g., synthetic vision enhancements, weather, etc.) may overlay an original image (i.e., view) the data can, at any time, be removed from the view.
With reference now to FIG. 6F, a flow diagram is illustrated showing an exemplary method 620 for displaying a real-time view in an aircraft, in accordance with an embodiment of the present invention. As indicated at block 621, an indication of a synthetic vision application is received. The indication may enable the synthetic vision application for the real-time view. At block 622, a synthetic vision application value to apply to the real-time view is identified. A synthetic vision enhancement is applied to the real-time view according to the synthetic vision application value at block 623. A modified real-time view is generated where the modified real-time view is enhanced by synthetic vision as indicated by the synthetic vision application value at block 624.
With reference to FIG. 6G, a flow diagram is provided showing yet another exemplary method 625 for displaying a real-time view within an aircraft. Initially, at block 626, an indication to enable synthetic vision is received. Based on the indication to enable synthetic vision, a second image including a synthetic vision enhancement is generated and the second image overlays the real-time image at block 627. At block 628, an indication to include weather data in the second image is received. A modified second image that includes each of the synthetic vision enhancement and the weather data is generated and the modified second image overlays the real-time image at block 629.
FIGS. 7A through 7D depict exemplary aircraft flight-control systems for displaying aircraft surfaces and receiving selections to control aircraft surfaces via TSIP 210. FIGS. 7A through 7D illustrate an exemplary user interface that may be displayed over the real-time image provided by TSIP 210.
FIG. 7A depicts an exemplary aircraft flight-control system 700, which includes an abbreviated title (FLT CONT) 701, and is configured to continuously display numerically and graphically the instantaneous positions of the aircraft's flight-control surfaces via flight-control surface representations. A menu option displayed on TSIP 210, such as FLT CONT menu option 737 of FIG. 7E, for example, may be used to select aircraft flight-control system 700.
FIG. 7A depicts flight-control surface representations with silhouette images to represent large flight surfaces. For example, a tail image 702 depicts a silhouette of the aircraft tail with a perspective view from the rear of the aircraft. Tail image 702 may display large flight surfaces including a vertical stabilizer image 703 and a horizontal stabilizer image 705. Smaller flight-control surface representations may be overlaid on the silhouetted images. For example, vertical stabilizer image 703 includes an overlaid representation of a smaller flight-control surface, namely a rudder display 704. Similarly, horizontal stabilizer image 705 may include overlaid representations of smaller flight-control surfaces, such as a left elevator display 706 and a right elevator display 707.
FIG. 7A also includes a left wing image 714 and a right wing image 718, which depict a silhouette of each wing with a perspective view from the rear of the aircraft. Left wing image 714 may include representations of smaller flight-control surfaces, including but not limited to, flaps, ailerons, speed brakes, and slats. Aileron and speed brake graphical indicators are both shown in figures FIGS. 7C and 7D. Slats are located on the leading edge of the wing and thus are not shown in the perspective view from the rear provided by FIG. 7A. Slats are typically deployed automatically with flaps but may be controlled independently within an embodiment of aircraft flight-control system 700. Left wing image 714 includes a left-wing outboard flap display 715, a left-wing middle flap display 716, and a left-wing inboard flap display 717. Similarly, right wing image 718 includes a right-wing outboard flap display 719, a right-wing middle flap display 720, and a right-wing inboard flap display 721. In FIG. 7A, flap displays 715, 716, 717, 719, 720, 721 are configured to indicate that all flaps are located in a fully retracted position.
In addition to aircraft flight-control surface representations, aircraft flight-control system 700 continuously monitors aircraft data busses to determine positions and intended movement of the flight-control surfaces and illustrates instantaneous positions of flight-control surfaces with position indicators via TSIP 210. The aircraft's data busses continuously receive data from sensors configured to determine actual positions of flight-control surfaces. Position indicators may include graphical and numerical indicators. An exemplary graphical indicator is a rudder graphical indicator 710, which indicates the aircraft's rudder position to the left or right of the aircraft's vertical stabilizer. Specifically, FIG. 7A shows an equally balanced rudder graphical indicator 710 to indicate a straight (i.e., unturned) rudder position with respect to the aircraft's vertical stabilizer. Similarly, a horizontal stabilizer graphical indicator 712 may indicate nose-up or nose-down positions of the aircraft's horizontal stabilizer with respect to a nominal position. FIG. 7A shows horizontal stabilizer graphical indicator 712 indicating a nose-up position of the aircraft's horizontal stabilizer. Typically aircraft left and right elevators move simultaneously with each other and independently of the horizontal stabilizer. Accordingly, left and right elevator displays 706, 707 may represent left and right elevator positions simultaneously with each other and independently of horizontal stabilizer image 705.
Many aircraft flight-control surfaces, including rudders, horizontal stabilizers and elevators, typically receive input for control from a control stick and/or rudder pedals. Aircraft flight-control system 700 is configured to continuously display instantaneous positions regardless of how the flight-control surfaces are controlled. In an embodiment, aircraft flight-control system 700 is configured to receive inputs via TSIP 210 to control aircraft flight-control surfaces including rudders, horizontal stabilizers and elevators.
FIG. 7B depicts an exemplary aircraft flight-control system 726 for displaying aircraft surfaces and receiving selections to control aircraft surfaces via TSIP 210. Aircraft flight-control system 726 is an example of aircraft flight-control system 700 of FIG. 7A. Graphical displays may be integrated within silhouette images. For example, graphical displays for flap positions are overlaid on wing images. Specifically, FIG. 7B shows left wing image 714 and right wing image 715 with flap displays 715, 716, 717, 719, 720, 721 indicating fully deployed flap positions, whereas FIG. 7A shows flap displays 715, 716, 717, 719, 720, 721 for fully retracted flap positions. Note that the flap displays shown in FIG. 7B are larger than the flaps displays shown in FIG. 7A to provide a size perspective and an intuitive representation of flap deployment that may be quickly observed. In an embodiment, flap displays for intermediate flap angles (e.g., seven and fifteen degrees) are correspondingly sized to represent intermediate flap angles. In other words, a view of left wing image 714 and right wing image 718 mimics an actual view of the aircraft's flaps from behind the aircraft.
In addition to graphical indicators, aircraft flight-control system 700 includes numerical indicators to continuously display instantaneous positions of flight-control surfaces. For example, a rudder numerical indicator 708 displays a numeric position in degrees with respect to the aircraft's vertical stabilizer. Specifically, FIGS. 7A through 7D show a zero degree position of rudder numerical indicator 708, indicating that the rudder is straight (i.e., unturned) behind the aircraft's vertical stabilizer. Similarly, a horizontal stabilizer numerical indicator 711 may display a position in degrees from a nominal level position. Specifically, FIGS. 7A through 7D show a minus three degree position of horizontal stabilizer numerical indicator 711 to indicate the aircraft's horizontal stabilizer position is three degrees below nominal. In an embodiment, aircraft flight-control system 700 includes numerical indicators for left and right elevators 706, 707.
In addition to graphical and numerical position indicators used to display aircraft flight-control information, aircraft flight-control system 700 may be configured to receive selections for controlling aircraft surfaces. For example, a series of displayed flap angle options are configured to receive selections of flap angles. FIGS. 7A through 7D show exemplary flap angle options including a zero degree flap option 722, a seven degree flap option 723, a fifteen degree flap option 724, and a thirty-five degree flap option 725. FIGS. 7A and 7C show zero degree flap option 722 highlighted, indicating that selection of a zero degree position was received for fully retracted aircraft flaps. FIGS. 7B and 7D show thirty-five degree flap option 725 highlighted, indicating that selection of a thirty-five degree position was received for fully deployed aircraft flaps.
Controlling flap angles by receiving flap angle selections via TSIP 210 is an improvement over prior art methods that use a monument mounted in the pedestal. An aircraft flap controller is essentially a lever mounted to an electrical resolver, which reads the position of the flap handle lever and converts that position to a digital signal. The signal is interpreted as a command to the flap driver in the wing, which moves the flap surface. Aircraft flight-control system 700 replaces the monument and generates identical digital signals upon receiving selections via TSIP 210. One advantage of using TSIP 210 is to avoid the need for the pedestal, which removes potential for foot strikes on the flap controller.
Aircraft flight-control system 700 displays actual (measured) positions of flight-control surfaces. Thus, if selection is received to deploy the flaps, for example, but one or more flaps does not move, the actual state of each flap is displayed, not the intended position. This provides the flight crew with greater situational awareness in the event of a suspected malfunction with a flight-control surface.
During movement of a flight-control surface, corresponding graphical and numerical indicators may display the actual position accordingly. For example, if the aircraft's rudder moves to the right, rudder graphical indicator 710 indicates a rudder position to the right, and rudder numerical indicator 708 displays a numeric position in degrees, with respect to the aircraft's vertical stabilizer. In an embodiment, rudder display 704 also graphically indicates a rudder position to the right with respect to the aircraft's vertical stabilizer. In another embodiment, rudder display 704 is configured to blink to represent rudder movement.
When a desired position is not reached by a flight-control surface, one or more warning signals may be displayed via the graphical and numerical indicators. For example, if selection is received for thirty-five degree flap option 725 but one or more flaps does not reach thirty-five degrees below nominal (i.e., fully deployed), the corresponding graphical indicator for each faulty flap may be highlighted in a different shade or color. For example, a nominal graphical indicator may be green, whereas a caution is amber and a warning is red. In an embodiment, a warning includes a flashing graphical indicator to attract attention. In another embodiment, noises are made to attract attention to a warning. If a surface that is supposed to work in unison, such as the three flap panels, malfunctions, the system changes the flight-control surface color from green to amber or red. As an example, selection is received to deploy the flaps to thirty-five degrees, but middle flap panel on the right wing deploys to seven degrees, middle flap display 720 would produce a warning signal. Thus the graphical representation of aircraft flight-control system 700 provides the flight crew with a quick visual guide to the state of each flight-control surface for improved situational awareness.
FIG. 7C depicts an exemplary aircraft flight-control system 727 for displaying aircraft surfaces and receiving selections to control aircraft surfaces via TSIP 210. Aircraft flight-control system 727 is an example of aircraft flight-control system 700 of FIG. 7A. Aircraft flight-control system 727 includes a left wing aileron display 728 and a right wing aileron display 729. Ailerons are flight-control surfaces used to roll an aircraft for banking while turning. Ailerons are typically activated when a pilot makes an input with a control stick but may be controlled via TSIP 210 as an embodiment of aircraft flight-control system 727. The resulting position of the ailerons may be displayed on TSIP 210 via aircraft flight-control system 727. For example, when a right banking turn has been initiated, the aircraft's left wing aileron drops below the wing and the aircraft's right wing aileron lifts above the wing. Accordingly, aircraft flight-control system 727 displays left wing aileron display 728 below left wing image 714 and right wing aileron display 729 above right wing image 718, as shown in FIG. 7C. In certain situations both ailerons of an aircraft may be in a position above the wing for slowing the aircraft without rolling (see for example, FIG. 7D).
FIG. 7D depicts an exemplary aircraft flight-control system 730 for displaying aircraft surfaces and receiving selections to control aircraft surfaces via TSIP 210. Speed brakes are flight-control surfaces used to slow an airplane by creating drag. FIG. 7D illustrates exemplary locations of a left wing speed brake display 731 and a right wing speed brake display 732 above middle flap displays 716, 720 on top of left and right wing images 714, 718, respectively. Each aircraft speed brake may include one or more panels. For example, FIG. 7D shows two panels per left and right speed brake display, 731, 732, respectively. Speed brakes are deployed typically during landing but also during flight, by using a lever next to throttles on the pedestal, and aircraft flight-control system 730 is configured to display the resulting speed brake positions. Specifically, FIG. 7D illustrates fully deployed speed brakes with left and right wing speed brake displays 731, 732 shown above left and right wing images 714, 718, respectively. In an embodiment, left and right speed brake displays 731, 732 are configured to receive selections for controlling positions of the aircraft's speed brakes.
FIG. 7E depicts an exemplary TSIP 735, which is an example of TSIP 210 of FIG. 2. FIG. 7E illustrates a combined mode controller and engine indicator 736 located in the upper middle portion of TSIP 735. Combined mode controller and engine indicator 736 displays a mode controller for controlling aircraft autopilot options and for visualizing engine information. In an embodiment, combined mode controller and engine indicator 736 is configured to be displayed in a convenient location between the pilot and co-pilot, as shown in FIG. 7E, but it may be displayed in any location on TSIP 210 without departing from the scope hereof. Aircraft flight-control system 700 may be selected from a menu, such as menu 150 of FIG. 1. Specifically, a FLT CONT 737 menu option may be used to select aircraft flight-control system 700, as shown in FIG. 7E.
FIG. 7F depicts a combined mode controller and engine indicator 740, which is an example of combined mode controller and engine indicator 736 of FIG. 7E. Combined mode controller and engine indicator 740 is designed to represent the shape of an aircraft's fuselage and engine cowlings, wherein the fuselage portion includes a mode controller 741 and the engine cowlings include a left engine indicator 750 and a right engine indicator 755. Combined mode controller and engine indicator 736 receives data from the aircraft's data busses and processes data using onboard computer 201 to determine left and right engine performance and displays the performance data on TSIP 210.
Mode controller 741 includes options for selection of various autopilot control functions via TSIP 210 including, but not limited to, Flight Level Change (FLC) 742, Autopilot (AP) 743, Altitude (ALT) 744, Vertical Speed (VS) 745, Vertical Navigation (VNV) 746, and Flight Director (FD) 747. Once selection of an autopilot mode is made, the respective portion of mode controller 741 may be highlighted, with a different shade or color for example.
Left engine indicator 750 and a right engine indicator 755 provide the flight crew with a graphical and numerical representation of engine performance and status. FIG. 7F shows an exemplary combined mode controller and engine indicator 740 for a dual-engine aircraft, but combined mode controller and engine indicator 740 could be configured to display engine indicators for a single-engine or triple-engine aircraft, without departing from the scope hereof.
Left engine indicator 750 includes a fan speed numerical display 751 and a fan speed graphical display 752. Similarly, right engine indicator 755 includes a fan speed numerical display 756 and a fan speed graphical display 757. Fan speed numerical displays 751 and 756 include numerical indicators of fan speed, for example, as a percentage of a pre-determined maximum fan speed, corresponding to the aircraft's left and right engine fan speeds, respectively. Fan speed graphical displays 752 and 757 include graphical indicators of fan speed, such as a graphical dial for example, corresponding to fan speed of the aircraft's left and right engines, respectively. Graphical displays 752 and 757 may include various shading or coloring to convey fan speed information. For example, fan speeds less than eighty percent may be colored green, while fan speeds between eighty and eighty-nine percent may be colored amber to indicate caution, and fans speeds of ninety percent or greater may be colored red to provide a warning signal. In an embodiment, fan speed graphical displays 752 and 757 include gradients of shading or coloring between different shades or colors, respectively. In an embodiment, fan speed numerical displays 751 and 756 include coloring or shading that matches fan speed graphical displays 752 and 757, respectively.
Left engine indicator 750 includes an Interstage Turbine Temperature (ITT) numerical display 753 and an ITT graphical display 754. Similarly, right engine indicator 755 includes an ITT numerical display 758 and an ITT graphical display 759. ITT numerical displays 753 and 758 include numerical indicators of temperature, for example in degrees Celsius, corresponding to measured temperature of the aircraft's left and right engines, respectively. ITT graphical displays 754 and 759 include graphical status indicators that change shade or color, for example, corresponding to temperature changes for the aircraft's left and right engines, respectively, and to provide warnings of anomalous performance. In an embodiment, ITT numerical displays 753 and 758 change shade or color to match the shade or color of ITT graphical displays 754 and 759, respectively
Each of the numerical and graphical displays for the engine indicators, shown in FIG. 7F and described above, may be configured to receive selections for responding to warning signals. For example, selection of a numerical or graphical display provides a list of options displayed on TSIP 210, which may include standard operating procedures and checklists from databases 230 for alleviating anomalous performance.
FIG. 7G depicts an exemplary aircraft flight-control method 770 for controlling aircraft flight-control surfaces via TSIP 210. In step 771, a list of menu options is presented. In an example of step 771, a list of menu options, including a flight-control option 737, is presented on TSIP 210, as shown in FIG. 7E.
In step 772, a selection of an aircraft flight-control function is received. In an example of step 772, selection of aircraft flight-control system 700 (of FIG. 7A) is received via flight-control option 737 of TSIP 210, as shown in FIG. 7E.
In step 773, an indication is received to identify a flight-control surface to control. In an example of step 773, an indication is received to control flaps via flap angle options including zero degree flap option 722, seven degree flap option 723, fifteen degree flap option 724, and thirty-five degree flap option 725, as shown in FIGS. 7A through 7D. Note that aircraft flight control system 700 may be configured to continuously display instantaneous positions of flight-control surfaces, before, during and after an indication is received to control flight-control surfaces.
In step 774, a selection is enabled to initiate a position change for the selected flight-control surface. In an example of step 774, flap angle options are enabled for selection to change flap positions including zero degree flap option 722, seven degree flap option 723, fifteen degree flap option 724, and thirty-five degree flap option 725, as shown in FIGS. 7A through 7D. In an embodiment, zero degree flap option 722 is selected, as shown in FIGS. 7A and 7C. In another embodiment, thirty-five degree flap option 725 is selected, as shown in FIGS. 7B and 7D.
In step 775, a corresponding movement to a selected position is verified for the aircraft flight-control surface. Example flight-control surfaces include the aircraft's horizontal stabilizer, elevator, rudder, aileron, speed brake, and flap. Movement of flight-control surfaces may be controlled by aircraft flight-control system 700 or by other automatic or pilot initiated controls such as a control stick or rudder pedals. In an example of step 775, following selection of zero degree flap option 722, flap displays 715, 716, 717, 719, 720, 721 are configured to indicate fully retracted flap positions and zero degree flap option 722 is highlighted, as shown in FIGS. 7A and 7C. Fully retracted flap positions are measured, for example, by sensors configured to detect each fully retracted flap and send a corresponding signal to TSIP 210 via onboard computer 201. In another example of step 775, following selection of thirty-five degree flap option 725, flap displays 715, 716, 717, 719, 720, 721 are configured to indicate fully deployed flap positions and thirty-five degree flap option 725 is highlighted, as shown in FIGS. 7B and 7D. Fully deployed flap positions are measured, for example, by sensors configured to detect each fully deployed flap and send a corresponding signal to TSIP 210 via onboard computer 201. Example sensors include contact switches, magnetic contact switches, resolvers, and non-contact interlock switches.
Step 776 is a decision to determine if the selected position deviates from an actual position. If in step 776, the selected and actual positions are determined to be the same (i.e., they essentially do not deviate from one another), then method 770 proceeds to step 777 to end. In an example of step 776, following selection of thirty-five degree flap option 725, fully deployed flap positions are measured, and method 770 proceeds to step 777 to end. Because aircraft flight-control system 700 is configured to continuously display actual flight-control surface positions, step 776 is both simple and intuitive to perform. For example, aircraft flight-control system 726 instantaneously displays the actual position of fully-deployed flaps by highlighting thirty-five degree flap option 725 and showing flap displays 715, 716, 717, 719, 720, 721 in their fully deployed configuration, as shown in FIG. 7B.
If in step 776, the selected and actual positions are determined to deviate from one another (i.e., they are not essentially the same position), then method 770 proceeds to step 778 to display a warning signal to indicate that the selected position deviates from the actual position of the control surface. Step 778 is followed by step 779 to present a list of selections for possible responses to the warning signal. Example responses include silencing an audible warning signal, stopping a warning signal from flashing, resetting a flight-control surface to its nominal position, and repeating selection for a desired position. In step 780, an indication is received of a selected response to the warning signal, after which method 770 returns to step 775 to verify movement of the selected position to the actual position.
In embodiments, awareness-enhancing indications are communicated by displaying them on the touch screen instrument panel. In order to provide a frame of reference, FIG. 8A shows the touch screen instrument panel 100 in a pre-alert status before any warnings have been triggered. As can be seen, no windows are shown being opened up on the display 800, and the terrain image and other normal in-flight content are plainly visible. Further, none of the menu buttons 150 are presented in a way that distinguishes them from the others, other than identifying markings.
This changes, however, when an alert is received from the aircraft systems. Referring now to FIG. 8B, a process flow diagram 801 is representative of alert processes which might be executed on the computer 201 to increase crew awareness. In a first step 802, alert information is received from an aircraft system. In one embodiment, this information might include either TCAS or TAWS information or alerts/warnings from component 280 (See FIG. 2). Alternatively, the message might be received from aircraft flight equipment 250 regarding, e.g. an issue regarding lighting, de-icing equipment, control surfaces, etc. The information could regard any of the aircraft systems shown in FIG. 2. Regardless of the source, the type of information, when received, is normally associated with a severity level. More specifically, a level of urgency in which some corrective measures should be taken. Thus, in a step 803, the level of severity of the information is identified. For example, four levels of severity might be employed. A first level of severity may be called “informational” and colored white for conditions that do not require flightcrew response, but are for informational purposes only. A second level of severity may be called “advisory” and colored cyan (or blue) for conditions that require flightcrew awareness and may require subsequent flightcrew response. A third level of severity may be called “caution” and colored amber (or yellow) for conditions that require immediate flightcrew awareness and subsequent flightcrew response. A fourth level of severity may be called “warning” and colored red for conditions that require immediate flightcrew awareness and immediate flightcrew response. These severity levels may be referred to as part of the aforementioned color coding scheme as will be discussed hereinafter.
In a Step 804, assuming the information regards an alert at a sufficient severity level, the computer 201 causes an awareness-enhancing indication, which, in an embodiment could be a peripheral display made to alert the crew of the existence of a warning. More specifically, in some embodiments, the display is made peripherally at one or more locations. In yet further other embodiments, the display is made substantially around the entire periphery of the touch screen as can be seen in the embodiment disclosed in FIG. 8C.
Referring to FIG. 8C, it can be seen that the state of the panel shown in FIG. 8A has changed to include the peripherally displayed graphic 813. In one embodiment, the awareness-enhancing indication is color-coded, for example, red for an extreme emergency or warning, and amber or yellow for a less extreme emergency or caution. With respect to alert information that is at lower severity levels, a process running on computer 201 may result in no peripheral graphic being displayed at all. In further embodiments, a peripheral warning graphic displayed will pulsate to draw additional extra attention. It should be evident to those skilled in the art that various colors and attraction inducing measures could be selected in order to meet this objective. It should also be evident that because of the peripheral location of the warning indication, that the crew is able to clearly see and maintain the use of most of the display area 813, while at the same time, the indication pulsing and colored at the margins is impossible to miss.
In other embodiments, or in addition to, or instead of the margin-displayed indication, the awareness-enhancing indication is provided in the form of highlighting menu options. “Highlighting” or “highlighted” as used herein means that an item is made to be differentiated from other items, or otherwise modified to increase awareness relative to that item. The use of the term should not be interpreted as requiring any particular color or other further restrictive constructions unless otherwise specified.
In terms of the process embodiment disclosed in FIG. 8B, it can be seen that a crew alert button 805 is subjected to highlighting. In terms of look-and-feel, FIG. 8C shows the crew alert button 814 as it might be highlighted on the menu 150 to enhance awareness (e.g., the crew will know that it is a menu item that should be selected to learn more about the problem, and also redress the problem).
Aside from the crew-alert button illumination (CAS) shown in 814 of FIG. 8C and shown as Step 805 in FIG. 8B, a Step 806 causes the illumination of one or more system buttons (e.g., menu buttons 815 and 817, also in FIG. 8C).
Each of these menu buttons 814, 815, and 817 can be highlighted in a number of different ways. In some embodiments, they are illuminated in a color that is the same of the particular warning level identified in Step 803. For example, for an extreme alert, a button might be illuminated in red—a color that those skilled in the art recognize as indicating a high level of seriousness. For less serious, but still important situations, the buttons might be illuminated in yellow. For moderately important situations the coloring might be blue, and for less serious items the coloring might be white.
Once a crew member identifies an alert exists as described wherein the peripheral area 812 is illuminated, in buttons 814, 815, and 817 are similarly highlighted by illumination, corrective measures can be taken. Button 815 “ELECT” provides, for example, electrical system schematic diagrams (see FIG. 8 and description below). Button 817 “MAINT” provides, for example, menu options for accessing maintenance issues (see FIG. 8G and description below). In order to assist the crew member in this regard, a step 807 provides that when a crew member selects the crew alert button 814, FIG. 8D shows that this will bring up a window 819 in a Step 807 where bars 821, 822, 823, and 824 are displayed. Each of bars 821, 822, 823, and 824 represents a system for which an alert exists.
Looking more closely at the crew alertness window 819, the window is initially presented in a collapsed format (as shown in FIG. 8D), but is expandable. More specifically, if the user clicks on any of bars 821, 822, 823, and 824, existing in FIG. 8D can be expanded as shown in the screen 826 shown in FIG. 8E. Note that sensed data is continuously displayed providing improved situational awareness for responding to a fault. For example, bar 823 includes a wingtip temperature reading and bar 824 includes battery voltage, current and temperature.
Referring to FIG. 8E, and moving from bottom to top, the “APU ON” bar 821, e.g., might be color coded white to represent a low priority state of alert. One bar up, the “APU FIRE BOTTLE LOW” Bar 822 might be colored blue to reflect a slightly more concerning alert level. Above that, a bar 823 for “RIGHT WING TIP COLD” is shown in expanded form, a user having selected it. Like with bars 821 and 822, bar 823, in the present embodiment, will be color coded with respect to severity level. For example, bar 823, in embodiments, could be colored yellow, reflecting a serious event, but not an emergency.
A crew member concerned about the warning is then able to click on, and thus expand bar 823, revealing means to correct the situation. Here, temperature sensors have detected a temperature, displayed in bar 823, that is below a predetermined setpoint. Thus, the expansion of bar 823 displays an appropriate solution, that being “TURN ON RIGHT WING ANTI-ICE” which is displayed next to a button 827 labeled with “RH WING”. In embodiments, action button 827 will also be highlighted in the same color of warning indication (yellow) as has been used to lead the user through the process. If the crew member selects action button 827, the anti-ice equipment will be activated with respect to the right wing, thus correcting the problem of potential ice buildup.
Bar 824, labelled as “LEFT BATTERY OFF”, would operate in much the same way. For example, it might also be displayed at its respective severity level, e.g. yellow here, indicating a serious situation needing to be dealt with, but not emergency situation. Note that bar 824 may include pertinent information, such as real-time data from sensor measurements for battery voltage, current and temperature, for example. When Bar 824 is expanded as shown in FIG. 8E, an appropriate solution is displayed. For example, the user is told to “TURN ON LEFT BATTERY”, and provided with a selectable field/button 828 (here “LH BATT”) which when selected will turn the left battery back on, thus correcting the problem.
Procedurally speaking, the crew-alert processes enable the reaching of a solution to the warning by increasing awareness (leading the user through menus using color-coded highlighting). In FIG. 8B, these processes are represented in a Step 807. Then, when the crew makes the corrective action, the process moves on to a Step 809 where the computer receives the remedial action due to the touch screen selection made (e.g., by activating either of buttons 827 or 828).
The crew is also offered an alternative approach to reaching the same solution. More specifically, given an alert, highlighting also directs the user to find a solution to the problem by looking at a particular system involved. As will be recalled, from the discussions involving FIG. 8C, and at the same time reviewing FIG. 8B, a step 806 causes the highlighting of one or more system items (e.g., menu buttons 814 and 816 also in FIG. 8C) as is expressed in the process diagram of FIG. 8B as a step 808.
Upon the selection of highlighted menu item 815 (labeled as “ELECT” in FIG. 8F), a window 825 will be called up (see FIG. 8D). This window is shown in more detail in FIG. 8. Looking to FIG. 8, it is shown that a schematic of the electrical system is displayed. When the system screen 829 is presented, the particular component of interest will be highlighted. Here, the left-hand-side battery, or “LH BATT” 830 will be highlighted. In some embodiments, the highlighting will be in the color reflective of the warning level. For example, here, yellow just like with the crew-alert processes. If the crew member touches the “LH BATT” button, the battery will be turned back on to correct the error. Thus, this is another, alternative to direct a crew member to an appropriate solution by enhancing awareness. In other words, the system-focused processes expressed in steps 806 and 808 give the crew an alternative guided solution to reaching remedial step 809 aside from the crew-alert processes offered by following steps 805 and 807.
A similar process would also be afforded to a crew member in addressing the problem with the anti-icing system reflected by the highlighting of system button 816 (entitled “ANTI ICE”). Assuming that all the remedial actions have been taken, the computer will then turn off the peripheral warning and remove the highlighting in a Step 810.
Another aspect of the touch-screen instrument panel enables the bringing up of a graphical representation of at least one system component (e.g., possibly a device that is a part of the aircraft flight equipment 250, see FIG. 2), and then displaying information regarding a real-time value for an aircraft-parameter proximate the device relevant. The terms “graphical” or “graphic” as used herein should not be construed as requiring any particular level of vividness or realism. These terms mean simply that the graphic is identifiable as being a resemblance of something.
Referring back to FIG. 8C, it can be seen that a maintenance “MAINT” button 817 is shown. When a crew member activates this button, a window like that shown in FIG. 8G is displayed. On initial opening up, all four of the bars (e.g., 832 and the three above it) would all be in a collapsed state (see discussions regarding screen 819 in FIG. 8D). FIG. 8G, however, shows two of the bars (the “PRESSURE” and “DIAGNOSTICS” bars) have been expanded by the user. It can be seen that the “PRESSURE” bar 832 has been expanded to reveal a graphic representation of a nose wheel landing gear arrangement symmetrically paired between left and right landing gear. Additionally, the real-time values for tire pressures are shown for each tire in each tire tandem. These graphical representations make it very convenient for the user in that they are able to graphically associate the real-time parameter values (e.g., PSI) with the actual physical components in the proper orientation. For example, it can be seen upon looking at the right wheel 833, that a value 834 in the right outboard tire 835 is abnormally low (25 PSI versus the normal 45 PSI). The combination of real time parameter values (e.g., tire pressures) along with the physical representations of the components makes it easy for the user to identify the problem.
It should also be understood that this maintenance window can also be brought up as a result of an alert issued. This might occur, e.g., when a parameter value (e.g., PSI) is identified as being abnormally low (e.g., the value of 25 PSI value in tire 835). Referring back to the process diagram 801 shown in FIG. 8B, an abnormal pressure level 834 detected in the left tire would trigger a warning from the aircraft systems. This warning would result in the highlighting of maintenance button 817 (according to step 806) and then, upon receipt of a selection of that button by a crew member, the maintenance window of FIG. 8G would be brought up. Bar 832 would, at that time, be collapsed, but would be highlighted in the relevant color (the same color, e.g., yellow, currently used in the highlighting of the menu item 817 and in the display of the margin warning 812). A click on the highlighted bar by a crew member, will expand the “PRESSURE” bar 832 revealing graphical representations of the wheel components as shown in FIG. 8G. This gives the crew member an additional level of awareness regarding the relative orientations of actual physical device having the problem.
Additionally, the warning-causing parameter value display 834 and/or the particular device (e.g., tire 835) in which the abnormality is occurring are (in embodiments) highlighted in a color indicating the severity level of the alarm (and consistent with the color currently used in the highlighting of the menu item 817 and margin warning 812). The result is that a user, in face of a system abnormality, is quickly navigated to the source of the problem, and can easily identify the real-time value relevant to that problem.
Expanding of the “DIAGNOSTICS” bar 836 (as shown) gives the user the ability to examine the states of the inputs and outputs of various PC cards by selecting (i.e. touch) any of the particular cards listed. Additional maintenance items may be retrieved from the maintenance window along with document look-ups stored on databases 230. This feature provides an aircraft maintenance crew with improved access to relevant maintenance information.
In another aspect which enhances crew awareness, processes are provided which give the crew a historical context for parameter values. Referring to FIG. 8C, selection of the “PROP” button brings up a screen 837 shown in FIG. 8H. Screen 837 shows one of many other possible arrangements where real time values are displayed in a historical context. These values will be recorded over time by computer 201 utilizing a database (e.g., in one of a number of databases 230 in FIG. 2). Recorded and time-stamped values for parameters (e.g., pressures, temperatures) are then called up and continually displayed as is depicted in an oil temperature chart 838 and an oil pressure chart 839. In the embodiment disclosed, chart 838 reflects two lines, a first plot 843 representative of an oil temperature for the left hand engine over time, and a second plot 844 representative of an oil temperature for the right hand engine over time. The real time current values 840 are displayed as shown for chart 838. Chart 838 includes time on an X axis 841, and includes the relevant parameter value (here, oil temperature) on a Y axis 845.
Similarly, oil pressure chart 839 enables the crew to see not only real-time values 842, but also to view them in a historical context. The historical nature of these charts is beneficial because the crew member is able to see abnormalities not only in the real time value 840, but also in the context of the past for those values.
