Embodiment 1

[0053] Example 1: Calculation example of maximum take-off weight

[0054] Assume that the initial state information of the aircraft input by the human-computer interaction module is shown in Table 1:

[0055] Form 1 Human-computer interaction input information

[0056]

[0057] According to the departure airport and runway identification input by the human-computer interaction module, the corresponding runway length, slope and airport altitude are queried in the navigation database, and the results are shown in Table 2:

[0058] Form 2 navigation database query information

[0059]

[0060]

[0061]Corrects the available runway length based on the slope and input wind component. In the performance database, relevant data are shown in Table 3:

[0062] Table 3 Slope, wind component correction runway length performance table

[0063]

[0064] The length of the runway is 3200m≈10499ft. Since the slope of the runway is 0%, the length of the runway corrected by the ...

Embodiment 2

[0076] Embodiment 2: Calculation of descending vertices:

[0077] In order to accurately land to the target airport, it is necessary to calculate in advance the coordinate position of the apex of descent when the aircraft finishes cruising and enters the descent phase according to the descent performance of the aircraft.

[0078] Assume that the information input by the human-computer interaction module is shown in Table 5:

[0079] Table 5 Human-computer interaction interface input-TOD

[0080]

[0081] First, query the descent distance in the descent performance data table according to the input cruising altitude, and the relevant performance data are shown in Table 6:

[0082]

[0083] According to the input APCH program, query the expected altitude of the final approach point in the navigation database is 1503m≈4931ft, the input cruise altitude is 9000m≈29528ft, the landing weight is the cruise weight of 60000kg, and the interpolation calculation from the table 6 de...

Abstract

The invention relates to a performance management system based on a fixed-wing aircraft. The system comprises a human-computer interaction module, a processing module, and a storage module; a performance database is pre-stored in the storage module; the processing module calculates or looks up the flight envelope and / or the optimized flight reference data according to the initial performance dataof the aircraft input by the human-computer interaction module. The invention builds an onboard performance database based on the aircraft performance manual; depending on the software to achieve automatic performance check of performance data, real-time performance data calculation is achieved; and by means of the database management tool, performance query service and the optimal trajectory reference are provided for the crew during the flight process, which can effectively reduce the pilot burden, reduce the operation error rate, improve flight efficiency and save flight cost.

Description

technical field [0001] The invention relates to a performance management system based on a fixed-wing aircraft. Background technique [0002] Performance management is one of the basic functions of the flight management system. The flight management system should be able to use the flight plan and performance database to calculate the relevant performance parameters displayed on the display device, and complete the aircraft performance calculation, so as to realize vertical track prediction and vertical guidance and other functions. Performance management plays an important role in improving the safety and economy of aircraft. [0003] At present, the performance management of civil aircraft and military aircraft mainly relies on pilots to manually consult the aircraft performance manual, which makes the preparation time before flight long, cumbersome and error-prone. The integrated performance calculation function in the flight management system is not perfect enough to p...
