Description

Technical Field

[0001] The present invention belongs to the field of aviation technology, and relates to a method and device for height indication in the vertical navigation display area of an aircraft. Background Art

[0002] The vertical navigation display area presents information diagrams such as the flight vertical path, airports, waypoints, etc. based on the instantaneous calculation of the current flight plan by the flight management system, and is used for flight guidance and performance reference. When the pilot is flying the aircraft, the pilot should be able to obtain the current flight altitude of the aircraft and the relevant reference altitudes of information diagrams such as the flight vertical path, airports, waypoints, etc. through the height indication in the vertical navigation display area.

[0003] When designing the height indication in the vertical navigation display area of traditional transport aircraft, a form with fixed scale indications from the minimum flight altitude to the maximum flight altitude is often adopted, and the height indication accuracy is fixed, with relatively low indication accuracy. With the development of aircraft design technology, the performance of aircraft has been significantly improved, and pilots pursue more refined flights. The height indication in the vertical navigation display area of traditional transport aircraft does not meet the current flight situation, and the indication accuracy is too low, which is likely to cause the pilot to misread altitude information such as the current flight altitude and the relevant reference altitudes of information diagrams such as the flight vertical path, airports, waypoints, etc. during flight. Summary of the Invention

[0004] The present invention provides a method and device for height indication in the vertical navigation display area of an aircraft. Compared with the traditional method for height indication in the vertical navigation display area of an aircraft, a more refined indication method is given from multiple aspects such as the design of the height indication scale band, the design of flight height indication, and the design of height indication for information diagrams such as the flight vertical path, airports, waypoints, etc., aiming to solve the problem that the traditional method for height indication in the vertical navigation display area of an aircraft does not meet the current display requirements of aircraft, enabling the pilot to obtain altitude information such as the current flight altitude and the relevant reference altitudes of information diagrams such as the flight vertical path, airports, waypoints, etc. more accurately during flight, and improving the reliability and safety of flight.

At the same time, obtain the flight altitude H1 at the current moment of the aircraft and the flight altitude H0 at the previous moment;

[0007] S1. Determine whether P1 = P0; if so, enter S2; if not, when P1 > P0, enter S3, and when P1 < P0, enter S4;

[0045] S31. The scale value of the height indication scale tape changes according to P1, and at the same time, determine whether H1 is greater than or equal to X1; if yes, the aircraft symbol remains stationary, and the height indication scale tape scrolls to the position where the aircraft symbol indicates H1 while the precision value changes; if no, when H0 > X0, the height indication scale tape first scrolls to the position where the aircraft symbol indicates X1 while the precision value changes, and then the aircraft symbol moves vertically downward to the position indicating H1; when H0 <= X0, the aircraft symbol moves vertically downward to the position indicating H1 while the height indication scale tape changes with the precision value;

[0046] S32. The altitude indicator scale value changes according to P1. When H1 is greater than or equal to X1 and H0 is greater than or equal to X0, the aircraft symbol remains stationary, and the altitude indicator scale rolls to the position indicated by the aircraft symbol H1 as the accuracy value changes. When H1 is less than X1 and H0 is less than X0, the aircraft symbol moves vertically to the position indicated by H1 as the altitude indicator scale changes with the accuracy value. When H1 is greater than or equal to X1 and H0 is less than X0, the aircraft symbol first moves vertically upward to the position indicated by X1 as the altitude indicator scale changes with the accuracy value, and then rolls to the position indicated by H1. When H1 is less than X1 and H0 is greater than or equal to X0, the altitude indicator scale first rolls to the position indicated by X1 as the altitude indicator scale changes with the accuracy value, and then moves vertically downward to the position indicated by H1.

[0047] S33. The altitude indicator scale value changes according to P1. It is determined whether H1 is greater than or equal to X1. If so, the aircraft symbol remains fixed, and the altitude indicator scale rolls to the position indicated by the aircraft symbol H1 as the accuracy value changes. If not, when H0 is less than or equal to X0, the aircraft symbol moves vertically to the position indicated by H1 as the altitude indicator scale changes with the accuracy value. When H0 is greater than X0, the altitude indicator scale first rolls to the position indicated by the aircraft symbol X1 as the accuracy value changes, and then the aircraft symbol moves vertically downwards to the position indicated by H1.

[0048] S41. The altitude indicator scale value changes according to P1. At the same time, it is determined whether H1 is less than or equal to X1. If so, the altitude indicator scale remains fixed, and the aircraft symbol moves to the position indicating H1 as the accuracy value changes. If not, when H0 is less than X0, the aircraft symbol first moves vertically upward to the position indicating X1 as the accuracy value changes, and then the altitude indicator scale rolls to the position indicating H1. When H0 is greater than or equal to X0, the aircraft symbol remains fixed, and the altitude indicator scale rolls to the position indicating H1 as the altitude indicator scale changes with the accuracy value.

[0049] S42. The altitude indicator scale value changes according to P1. When H1 is greater than or equal to X1 and H0 is greater than or equal to X0, the aircraft symbol remains stationary, and the altitude indicator scale scrolls to the position indicated by the aircraft symbol H1 as the accuracy value changes.

When H1 is less than X1 and H0 is greater than or equal to X0, the altitude indicator scale first scrolls to the position indicated by the aircraft symbol X1 as the accuracy value changes, and then moves vertically downward to the position indicated by the aircraft symbol H1.

[0050] The first value is determined based on the minimum scale value of the display area and the scale precision value set by the pilot at the current time.

[0051] For example, when the height indicated by the height indicator icon is within the current display area of ​​the height indicator scale, the height indicator icon indicates the corresponding scale.

[0052] When the height indicated by the altitude indicator is outside the current display area of ​​the altitude indicator scale, the altitude indicator will remain at the top or bottom of the altitude indicator scale in half the size of the image.

[0053] The altitude indication information includes: preset altitude pointer and minimum air pressure altitude pointer.

[0054] For example, when the pilot is detected adjusting the compass range, the accuracy value P1 of the altitude indicator scale is determined based on the adjusted compass range. In this embodiment, the accuracy value P1 of the altitude indicator scale is proportional to the compass range.

[0055] For example, the first value is the sum of the smallest scale value and three times the precision value.

[0056] For example, when the altitude and horizontal distance of the indicator icon containing horizontal distance information are within the current display area of ​​the vertical navigation display area, it is displayed. The indicator icon containing horizontal distance information includes: flight vertical path, airport, and waypoint.

[0057] In one specific embodiment of the present invention:

[0058] 1. Altitude indicator scale design

[0059] like Figure 1As shown, the height indicator scale range is equal to the accuracy value * 4, with a minimum scale value of -1000m and a maximum scale value of 12000m.

[0060] The accuracy of the altitude indicator scale can be adjusted according to the compass range, specifically:

[0061] When the full range of the compass is less than or equal to 10km, the accuracy of the altitude indicator scale is 100m.

[0062] When the full range of the compass is 20km, the accuracy of the altitude indicator scale is 200m;

[0063] When the full range of the compass is 40km, the accuracy of the altitude indicator scale is 500m;

[0064] When the full range of the compass is 80km, the accuracy of the altitude indicator scale is 1000m;

[0065] When the full range of the compass is greater than or equal to 160km, the accuracy of the altitude indicator scale is 2000m.

[0066] like Figure 2 As shown, the height indicator scale can change dynamically, and the specific display format is as follows:

[0067] When the current aircraft altitude is less than the minimum scale value (-1000m) + the current scale precision value * 3, the altitude indicator scale remains fixed, and the scale value starts from -1000. The aircraft symbol moves vertically up and down to indicate the current aircraft altitude. When the current aircraft altitude is greater than or equal to the minimum scale value (-1000m) + the current scale division value * 3, the aircraft symbol is fixed at 3 / 4 of the length of the altitude indicator scale, and the altitude indicator scale scrolls to indicate the current aircraft altitude in real time.

[0068] 2. Flight Altitude Indication Design

[0069] like Figure 2 As shown, the triangle symbol represents an airplane, indicating the airplane's current position.

[0070] The airplane symbol is fixed horizontally, with the right triangle vertex located at 0km on the horizontal scale. The airplane symbol can move vertically up and down, and the altitude indicator scale corresponding to the right-angled base is the airplane's current altitude.

[0071] The aircraft symbol can move vertically upwards to a position up to 3 / 4 of the altitude indicator scale length. As altitude increases, the aircraft symbol remains fixed while the altitude indicator scale moves.

[0072] 3. Design of altitude indication diagrams for flight vertical flight path, airports, waypoints, etc.

[0073] like Figure 3 As shown, information diagrams containing horizontal distance information, such as flight vertical path, airports, and waypoints, are displayed in the information diagram display area of ​​the map. The information diagram display changes with the accuracy value of the altitude indicator scale. Content outside the information diagram display area is not displayed.

[0074] like Figure 4 As shown, altitude indication information such as the preset altitude pointer and the minimum barometric altitude pointer are displayed on the altitude indication scale. When the indicated altitude is within the altitude indication scale area, the information icon is displayed on the corresponding scale; when the indicated altitude is outside the altitude indication scale area, the information icon remains at the top or bottom of the altitude indication scale in a 1 / 2 format.

[0075] For example, the 1 / 2 form can be changed from a solid line to a dashed line.
