ОПИСАНИЕ




УРОВЕНЬ ТЕХНИКИ



Aircraft cockpits commonly include one or more primary flight displays ("PFD") and one or more multi-function displays ("MFD"). The PFD may be configured to display situational flight information. This information may include, for example, speed, attitude, vertical rate, altitude, flight progress, GPS location, plotted versus actual course, etc. The MFD may be configured to display navigation route, map, weather radar, ground proximity warning system information, traffic collision avoidance information, and more. In multi-pilot aircraft, it is common for each pilot to have their own PFD and MFD. It is important that each pilot has the ability to control their own displays. As such, the PFD and MFD controls may generally be incorporated directly into the frame surrounding the PFD or MFD, respectively, or they may be located in a separate control unit placed elsewhere in the cockpit within reach of the corresponding pilot. However, depending on workflow within the crew, it may occasionally be desirable for one pilot to adjust the other pilot's displays. As such, it may be desirable for the controls for all of the displays to be within reach of both pilots. The only location in a cockpit that is easily accessible to both pilots is the center stack. Given that all of the flight controls must be within reach of both pilots, space on the center stack is limited.

Aircraft may also include a mode control panel ("MCP"). The MCP includes controls to input automated flight behavior. For example, the MCP may be used to enter instructions for the aircraft to hold a specific altitude, speed, or heading, to change altitude or speed at a specific rate; or to input a new heading, etc. Accordingly, the flight controls included on the MCP should be within reach of both pilots, and therefore, the MCP should be located on the center stack.

ПОДРОБНОЕ ОПИСАНИЕ



In this disclosure, reference may be made to the spatial relationships between various components and to the spatial orientation of various aspects of components as the devices are depicted in the attached drawings. However, as will be recognized by those skilled in the art after a complete reading of this disclosure, the devices, members, apparatuses, etc. described herein may be positioned in any desired orientation. Thus, the use of terms such as "above," "below," "upper," "lower," or other like terms to describe a spatial relationship between various components or to describe the spatial orientation of aspects of such components should be understood to describe a relative relationship between the components or a spatial orientation of aspects of such components, respectively, as the device described herein may be oriented in any desired direction.

In furtherance of the goals of efficient controller design and weight savings, this disclosure provides a single controller unit that combines the input controls of an MCP with the input controls of at least one PFD. The disclosed combined controller unit may be used on any aircraft, including fixed wing aircraft as well as rotorcraft. The combined controller not only saves space but saves weight and enables the cockpit to include PFD controls on the crowded center stack. Moreover, the combination of control units allows for the elimination of some inputs, as some of the inputs on the combined unit may perform multiple functions. In addition, the combined unit enables some of the inputs to act as back-up inputs for other functions in the event the main inputs fail. For example, the PFD controls may serve as backup controls for the MFD.

Referring to FIG. 1, a cockpit 101 of a rotorcraft is illustrated. Cockpit 101 includes a first primary flight display 103 and a second primary flight display 105 for the display of flight information to a first pilot and a second pilot, respectively. The flight information may include, but is not limited to, airspeed, altitude, attitude, heading, course deviation indicator, and map. The screens of first primary flight display 103 and second primary flight display 105 may be LCD, LED, or any other suitable type of display screen. The first primary flight display 103 may include a plurality of inputs 107 located on the frame thereof. Similarly, second primary flight display 105 may include a plurality of inputs 109 located on the frame thereof. These inputs 107, 109 may be soft keys or hard keys for the control of first and second primary flight displays 103, 105, respectively. In between first primary flight display 103 and second primary flight display 105 are first multi-function display 111 and second multi-function display 113. First and second multi-function displays 111, 113 may display navigation route, map, weather radar, ground proximity warning system information, traffic collision avoidance information, and more to the first and second pilot, respectively. First multi-function display 111 may include a plurality of inputs 115 in the frame thereof. Similarly, second multi-function display 113 may include a plurality of inputs 117 in the frame thereof. These inputs 115, 117 may be soft keys or hard keys for the control of first and second multi-function displays 111, 113. Located on a center stack 119, between the pilots, is a first multi-function control unit 121. Adjacent to first multi-function control unit 121 is a second multi-function control unit 123. In the embodiment shown in FIG. 1, both first and second multi-function control units 121, 123 are customizable touch screens configured for the control of first and second multi-function displays 111, 113, respectively. However, first and second multi-function control units 121, 123 may utilize buttons, bezels, dials, joysticks, or any other type of physical inputs, rather than, or in addition to, touch screens. Below first and second multi-function control units 121, 123 is a combined controller 125. Combined controller 125 is used to control first primary flight display 103, second primary flight display 105, and to control automated flight behavior. Automated flight behavior may include, but is not limited to, holding a specific altitude, speed, or heading, and changing altitude or speed at a specific rate.

As shown in FIGS. 2-5, combined controller 125 includes a panel 127 having a face 129 and an opposite back 131. Back 131 is configured to attach to a case 133.

As such, combined controller 125 has a preferred maximum width of 14.25 inches and a preferred maximum height of 3.70 inches. It is also preferred that combined controller 125 be configured as a line replaceable unit, and therefore, combined controller 125 should be entirely self-contained and be easily installed and removed from center stack 119. To aid in the quick installation/removal, combined controller 125 includes four pawl latches 141 configured to engage center stack 119. Pawl latches 141 are engaged with a tool, e.g., a hex wrench or a screw driver, via openings 143 in face 129.
