20180032073
The present subject matter relates generally to aerial vehicles.
One of the largest challenges to safety of flight is pilot automation and flight mode confusion. This is apparent in the systems used to automatically maneuver the aerial vehicle. In current aerial vehicles, the flight management system and the flight director are loosely coupled. Interactions with the flight management system are usually accomplished through a keyboard or cursor interface. Interactions with the flight director are controlled by the mode control panel. The mode control panel also has mechanisms to select which system, the flight management or the flight director, is in charge. The complexity of the current systems provides many opportunities for pilots to misinterpret data presented to them or understanding what the aerial vehicle is about to do. Further, pilots can enter incorrect input into various systems.
Aspects and advantages of embodiments of the present disclosure will be set forth in part in the following description, or may be learned from the description, or may be learned through practice of the embodiments.
One example aspect of the present disclosure is directed to a method for controlling an aerial vehicle. The method includes receiving a first signal from a first input device, wherein the first signal is related to a mode of a flight director. The method includes outputting a parameter on an output device, wherein the parameter is related to the mode. The method includes receiving a second signal from a second input device, wherein the second signal causes the parameter to change to a new parameter, and wherein the second input device is mechanically coupled to the first input device. The method includes outputting, by the one or more processors, the new parameter on the output device. The method includes receiving, by the one or more processors, a third signal from a third input device, wherein the aerial vehicle is controlled by the flight director based on the third signal, and wherein the second input device is mechanically coupled to the third input device.
Another example aspect of the present disclosure is directed to a system for controlling an aerial vehicle. The system includes a flight director that controls the aerial vehicle. The system includes a first input device that specifies one or more modes of the flight director. The system includes a second input device that specifies one or more parameters related to the one or more modes, wherein the second input device is mechanically coupled to the first input device. The system includes a third input device that confirms the one or more parameters, wherein the second input device is mechanically coupled to the third input device. The system includes an output device that displays the one or more parameters. The system includes one or more processors. The one or more processor are configured to transmit a signal to the flight director based on an engagement of the third input device, wherein the signal comprises the one or more parameters based on the second input device, and wherein the signal updates the flight director.
Other example aspects of the present disclosure are directed to systems, methods, aerial vehicles, avionics systems, devices, non-transitory computer-readable media for integrating a flight management system and a flight director of an aerial vehicle. Variations and modifications can be made to these example aspects of the present disclosure.
These and other features, aspects and advantages of various embodiments will become better understood with reference to the following description and appended claims. The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments of the present disclosure and, together with the description, serve to explain the related principles.
Detailed discussion of embodiments directed to one of ordinary skill in the art are set forth in the specification, which makes reference to the appended figures, in which:
Reference now will be made in detail to embodiments, one or more examples of which are illustrated in the drawings. Each example is provided by way of explanation of the embodiments, not limitation of the embodiments. In fact, it will be apparent to those skilled in the art that various modifications and variations can be made in the present disclosure without departing from the scope or spirit of the invention. For instance, features illustrated or described as part of one embodiment can be used with another embodiment to yield a still further embodiment. Thus, it is intended that the present disclosure covers such modifications and variations as come within the scope of the appended claims and their equivalents.
As used in the specification and the appended claims, the singular forms “a,” “an,” and “the” include plural referents unless the context clearly dictates otherwise. The use of the term “about” in conjunction with a numerical value refers to within 25% of the stated amount.
Example aspects of the present disclosure are directed to methods and systems that can allow integration of a flight management system of an aerial vehicle with a flight director of the aerial vehicle. The flight management system of the aerial vehicle can be similar to a global positioning system in a vehicle. The flight director can control the flight of the aerial vehicle. The flight director can operate in automatic modes. The flight director can operate in manual modes.
The aerial vehicle can utilize a single interface to control both the flight management system and the flight director. In a traditional system, a pilot can intend to make adjustments to an aerial vehicle which may not take effect if the aerial vehicle is in an automatic mode. The single interface can eliminate confusion regarding whether an aerial vehicle is in an automatic mode or a manual mode by using the single interface to make adjustments during all modes.
Methods and systems according to example embodiments of the present disclosure can integrate the single interface with the flight management system. The integrated single interface and flight management system can provide the input for the flight director. For instance, if the single interface indicates a manual mode, then the flight director can receive the manual instructions from the integrated single interface and flight management system. If the single interface indicates an automatic mode, then the flight director can receive a route (e.g., flight plan, flight path, etc.) from the flight management system.
In particular implementations, the single interface can include a first input device for selecting a mode. For instance, the first input device can be an outer knob used to select a mode. The single interface can communicate with an output device to display parameters related to the mode selected. The parameter can be a parameter indicative of a flight plan. The parameter can be a numeric parameter when the selected mode uses numerical parameters. For example, the parameter can be a numeric parameter representing a degree when the selected mode uses the numeric parameter to determine at what degree the head of the aerial vehicle should be pointed. The parameter can be an alphabetic parameter when the selected mode uses alphabetic parameters. For example, the parameter can be an alphabetic parameter representing an airport code when the selected mode uses the airport code to determine a route. For example, the parameter can be an alphabetic parameter representing waypoint identifier when the selected mode uses the waypoint identifier to determine a route. The parameter can include a combination of numerical and alphabetic parameters, or any other symbols. The output device can display a numerical parameter when a manual mode is selected by the first input device and an airport code and/or waypoint identifier when an automatic mode is selected by the first input device. The single interface can include a second input device for changing a parameter associated with the mode. For instance, the second input device can be an inner knob used to change the parameter. As the parameter is changed, the output device can be updated to include the changed parameter. The single interface can include a third input device for selecting the parameter. For instance, the third input device can be a button for selecting the parameter. The parameter displayed on the output device can be sent to the flight director for controlling the aerial vehicle when the third input device is engaged. In this way, the systems and methods according to example aspects of the present disclosure have a technical effect of integrating a flight management system of an aerial vehicle with a flight director of the aerial vehicle.
The aerial vehicle 100 can include one or more input device(s) 112 (e.g., in the cockpit 102) that can be configured to provide input to one or more system(s) of the aerial vehicle 100. The input device(s) 112 can include any device suitable to accept input from a user for interaction with the systems of the aerial vehicle 100. For example, the input device(s) 112 can include a keyboard, joystick, multi-way rocker switches, mouse, trackball, touch screen, touch pad, data entry keys, a microphone suitable for voice recognition, and/or any other suitable device. The input device(s) 112 can include an outer knob, an inner knob, and a button. In some implementations, the outer knob can be used to select a mode, such as a flight mode, inner knob can be used to cycle through parameters associated with the selected mode, and the button can be used to select a parameter associated with the mode. In some implementations, the input device(s) 112 can be configured to allow the user to interact with a graphic and/or textual data element provided for display on the display device(s) 110A-B. For example, a display device (e.g., the first display device 110A) can be used to display parameters associated with the selected mode.
The aerial vehicle can include a flight management system 114. The flight management system 114 can include one or more of the input device(s) 112. The flight management system 114 can be configured to manage the flight control of the aerial vehicle 100. For instance, the flight management system 114 can be configured to implement, manage, and/or control a flight mode, flight path, flight plan, flight trajectory, etc. for the aerial vehicle 100. For example, the flight management system 114 can include and/or determine a route associated with an airport code and/or a waypoint identifier. The flight management system 114 can be configured to receive input from a user. In some implementations, the flight management system 114 can receive user input via the one or more input device(s) 112. Additionally, and/or alternatively, the flight management system 114 can be associated with a display device (e.g., the first display device 110A) that the user can interact with and/or that can be configured to display information associated to the flight management system 114. For example, the first display device 110A can include one or more user interfaces. The first display device 110A can be operably coupled with the input devices 112 such that a user can interact with the user interface (e.g., cursor interaction via trackball, mouse, etc.) and the textual and/or graphical elements included in the user interface. Additionally, and/or alternatively, the first display device 110A can include a touch display screen that can allow a user to visualize the user interface on the touch display screen and interact with the user interface (and the flight management system 114) through the touch display screen. The flight management system 114 can be configured to implement one or more flight mode(s), flight plans, etc. of the aerial vehicle 100 selected by user input and display information associated with the one or more flight mode(s) on a display device (e.g., first display device 110A).
The aerial vehicle 100 can include a flight director 116. The flight director 116 can include one or more of the input device(s) 112. The flight director 116 can control an autopilot system. The flight director 116 can be configured to assist in the control of the trajectory of the aerial vehicle 100 with and/or without user (e.g., pilot) interaction. For instance, the flight director 116 can be configured to assist the aerial vehicle 100 to operate in various control modes. For example, the flight director 116 can be configured to assist the aerial vehicle 100 to operate in an “autonomous” control mode (e.g., no user control) and/or a “shared” control mode (e.g., some user control, some autopilot system automated control). In some implementations, the aerial vehicle 100 can operate in a “manual” control mode by which, for example, there is limited-to-no autopilot system automated control of the aerial vehicle 100. The flight director 116 can include a panel 118 that can be configured to, for example, display information related to the flight director 116 (e.g., flight paths, flight plans, routes, selected flight modes, control modes, parameters associated with selected flight modes, etc.).
In some implementations, the flight director 116 can be associated with a display device (e.g., the first display device 110A), such that the display device can display information associated with the flight director 116 (e.g., flight paths, flight plans, routes, selected flight modes, control modes, parameters associated with selected flight modes, etc.). In some implementations, the associated display device (e.g., first display device 110A) can include one or more user interface(s). For example, the first display device 110A can be operably coupled with the input devices 112 such that a user can interact with the user interface (e.g., cursor interaction via trackball, mouse, etc.) and the textual and/or graphical elements included in the user interface. Additionally, and/or alternatively, the first display device 110A can include a touch display screen that can allow a user to visualize the user interface on the touch display screen and interact with the user interface (and the autopilot system 116) through the touch display screen. In some implementations, the panel 118 can include the first display device 110A and/or a display device that can perform similar operations and/or functions, as described herein.
The aerial vehicle 100 can include a flight mode annunciator 120 that can be configured to inform the flight crew of a past, current, and/or future status of the aerial vehicle 100. For instance, the second display device 110B can be associated with the flight mode annunciator 120. The flight mode annunciator 120 can be configured to display (e.g., via the second display device 110B) one or more past, current, and/or future flight mode(s) associated with the aerial vehicle 100, as well as other information associated with the status of the aerial vehicle 100.
The input devices 112 in accordance with one or more embodiments of the present disclosure will be described in more detail in reference to
The numbers, locations, and/or orientations of the components of example aerial vehicle 100 are for purposes of illustration and discussion and are not intended to be limiting.

The output device 206 can be updated with a current parameter as the second input device 208 is engaged. The interface 200 can include a third input device 210. The third input device 210 can be used to select a parameter associated with the mode shown on the output device 206. The third input device 210 can be a button. Engaging the third input device 210 can cause the parameter associated with the selected mode on the third input device 210 and an indication of the selected mode to be transmitted to the flight director. In another embodiment, the indication of the selected mode can be transmitted to the flight director in response to engagement of the first input device 202. A flight plan output device 220 can display entries in a flight plan. The entries in a flight plan can include airport codes, waypoint identifiers, etc.
At (304), a parameter related to the mode can be outputted on an output device. The parameter can be a numeric parameter when the selected mode uses numerical parameters. For example, the parameter can be a numeric parameter representing a degree when the selected mode uses the numeric parameter to determine at what degree heading the nose of the aerial vehicle should be pointed. The parameter can be an alphabetic parameter when the selected mode uses alphabetic parameters. For example, the parameter can be an alphabetic parameter representing an airport code when the selected mode uses the airport code to determine a route. For example, the parameter can be an alphabetic parameter representing waypoint identifier when the selected mode uses the waypoint identifier to determine a route. The parameter can include a combination of numerical and alphabetic parameters, or any other symbols.

The second input device can surround the third input device. An outer circumference of the third input device can be in communication with an inner circumference of the second input device. The third input device can be on top of the second input device. Output of the flight management system can be input to the flight director. Input to the flight director can be output from the flight management system. In an aspect, the methods and systems described herein can eliminate direct user interaction with the flight director. In an embodiment, the new parameter can be entered as a top entry in a flight plan in response to the third signal. For example, if the new parameter is an entry in the flight plan, then the new parameter can be moved to the top of the flight plan. As another example, if the new parameter is a heading setting, then the heading of the aerial vehicle as specified by the new parameter can be entered as a top entry in the flight plan in response to the third signal. In an embodiment, input into the flight director can be the top entry in the flight plan.
