[0024] In order to more clearly illustrate the technical solutions provided by the present application, the following will briefly introduce the drawings. Obviously, the drawings described below are only some embodiments of the present application.
[0025] Figure 1 The display state of the upper front control panel in the automatic navigation state is shown in the schematic diagram.
[0026] Figure 2The figure shows the display state of the up front control panel in the given track and radio holding state in the present application.
[0027] Figure 3 The figure shows the up front control panel in the on state in the present application. DETAILED DESCRIPTION
[0028] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution in the present application will be described in more detail below in combination with the drawings in the present application.
[0029] The present application provides an automatic flight control system integrated with an avionics system, which cancels the traditional automatic flight control system control box, utilizes the control display resources of the avionics system of the aircraft, perfects the control display function of the automatic flight control system, and improves the manipulation of the pilot and meets the demand of real-time monitoring of the system state.
[0030] As shown in Figure 1 , the automatic flight control system provided by the present application utilizes the control display resources of the avionics system, mainly the up front control panel (UFCP) and the head up display (HUD), and there are several display modes for the automatic flight control picture peripheral key characters on the up front control panel: gray display, green display and high-light display. The gray display indicates that this mode is not allowed to be turned on, such as "radio holding" in Figure 1 ; the green display indicates that this mode is allowed to be turned on, and the pilot can select this automatic control mode, such as "altitude holding" in Figure 1 ; and the high-light display indicates that this automatic control mode is turned on, such as "automatic navigation" in Figure 1 .
[0031] In the automatic control mode arrangement of the up front control panel, the left side is the lateral control, the right side is the longitudinal control, the first row M1, M6 is the integrated control mode related to the avionics system, and the others are basic control modes. In the lateral control layout on the left side, the second row M2 is the track holding, and the third row M3 is the given track control (achieved by inputting a predetermined angle, for example, 120° in Figure 2 to achieve the given track flight), and the second row M2 and the third row M3 constitute the lateral control mode; the fourth row M4 is the indicated airspeed holding, and the fifth row M5 is the Mach number holding, and the fourth row M4 and the fifth row M5 constitute the automatic throttle control; in the longitudinal control layout on the right side, the second row M7 is the altitude holding, the third row M8 is the given altitude control (achieved by inputting a predetermined altitude, for example, 8.00km in Figure 1 to achieve the given g altitude flight), and the fourth row M9 is the radio altitude holding, and the second row M7 to the fourth row M9 constitute the longitudinal control mode.
[0032] The character content in the above layout does not change, and is called a basic control mode of automatic flight control, which is independent of the avionics mode.
[0033] The automatic control mode related to the avionics, such as automatic navigation, automatic return-to-field landing, automatic guidance, etc., is arranged in the first row of the upper front control panel. According to the avionics mode, the characters displayed in the first row also change, i.e., when the avionics is in the navigation mode, the automatic flight control system provides the function of automatic navigation, such as Figure 1 "automatic navigation" in the first row; when the avionics mode is return-to-field (APR), the automatic flight control system provides the function of automatic return-to-field landing, such as Figure 2 "azimuth hold", "glide slope hold" in the first row of the automatic return-to-field landing mode information; when the avionics mode is guidance, the automatic flight control system provides the function of automatic guidance, such as Figure 3 "manual guidance", "onboard guidance", "command guidance" in the first row of the automatic guidance mode information.
[0034] The middle and lower part of the upper front control panel has an automatic flight control system state display area for displaying the state of the automatic flight control system. The automatic flight control system state display area has basically the same display content as the surrounding keys, and has the same basic arrangement principle as the surrounding keys. The automatic flight control system state display area includes three display boxes, which are the horizontal control mode, the speed control mode, and the longitudinal control mode. The display of the three display boxes is not only displayed on the automatic flight control panel, but also displayed on the default screen of the upper front control panel.
[0035] The PFD displays the automatic flight state in real time to the pilot when the automatic flight control system enters the automatic control, such as the PFD displays the "AP" word in the center of the PFD, and the related information of the entered automatic control mode is displayed in the lower left corner.
[0036] The automatic flight control system of the present application has the following advantages:
[0037] 1) The traditional independent automatic flight control system control box is cancelled, and the space resource of the cockpit console is saved;
[0038] 2) The control display resource of the upper front control panel on the aircraft is used to arrange the selection screen of the automatic flight control function, and the state of the automatic flight control system mode is clearly displayed to the pilot, so as to complete the function mode selection and mode switching of the automatic flight control system;
[0039] 3) The function modes are displayed in partitions on the upper front control panel, which is convenient for the pilot to select and operate;
[0040] 4) Through the different display mode of the peripheral key, prompting the pilot in the current flight state, whether the function mode of each automatic flight control system is allowed to be turned on and whether it is turned on, etc.
[0041] 5) According to the state of the task system, providing the automatic flight control function based on the state of the avionics system;
[0042] 6) Using the display resources of the existing plane flat display to complete the state display of the automatic flight control system, facilitating the real-time monitoring of the pilot on the state of the automatic flight control system.
[0043] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can easily think of changes or replacements within the technical range disclosed in the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
