Problems solved by technology

[0003] In order to evaluate the quality of the pilot's landing operation, most airlines in my country currently monitor flights and evaluate pilot performance through the level and frequency of QAR overrun events, but this evaluation method can only be used for a specific technology in the landing process. Points for analysis and visualization, which have not been evaluated by quantitative judgment methods, which make it impossible to use the results of data analysis for further production management

Embodiment

[0050] The method of utilizing QAR data in the present embodiment to quantitatively analyze the landing operation quality of a fixed-wing aircraft comprises the following steps:

[0051] Step 1: Establish a landing operation quality evaluation model; that is, set the reference value of the landing operation quality scoring dimension. The reference values ​​of the set landing operation quality scoring dimensions include: key height data, throttle data, attitude data, slope and direction data, touchdown effect data, and consistency data. Specifically, the key altitude data include: landing start altitude, pulling start altitude, approaching leveling altitude; throttle data include: descent rate at closing throttle timing and reverse thrust action time; attitude data include: landing attitude, maximum value of landing attitude change rate, Tail strike risk value, attitude increase value after touchdown, nose wheel down time; slope and direction data include: touchdown slope, maxi...

Abstract

The invention discloses a method for quantitatively analyzing landing operation quality of a fixed-wing aircraft by using QAR data. The method is characterized by comprising the following steps: 1, establishing a landing operation quality evaluation model; 2, acquiring data of actual landing operation quality scoring dimensions in the landing process of the fixed-wing aircraft; 3, performing comparative analysis on the acquired data of the landing operation quality scoring dimension and a set reference value of the landing operation quality scoring dimension; and 4, obtaining a landing operation quality evaluation result according to the analysis result. According to the method, the problem of quantitative judgment through the model is solved, judgment based on the data model is carried out on multiple dimensions of aircraft landing, the error between the judgment standard and the actual situation can be clearly explained, the problem of non-uniform standards is effectively solved, andpilots can continuously improve their own skills according to the feedback of standardized data.

Description

technical field [0001] The invention relates to the technical field of flight quality monitoring, and specifically provides a method for quantitatively analyzing the landing operation quality of a fixed-wing aircraft by using QAR data. Background technique [0002] Flight accident statistics show that landing is the most dangerous stage of civil aircraft flight, and the incidence of accidents and unsafe incidents is significantly higher than other flight stages, because during the landing process, pilots need to face more operational tasks and the resulting Therefore, an accurate evaluation of the pilot's landing operation quality can provide a direct basis for evaluating the operational risk and overall safety level of the flight team, and provide an important reference for improving flight operation and training. [0003] In order to evaluate the quality of the pilot's landing operation, most airlines in my country currently monitor flights and evaluate pilot performance t...
