Embodiment Construction
[0086] Below in conjunction with accompanying drawing, the present invention is described in further detail:
[0087] The characteristic parameters have great practical significance for the study of the degree of risk of heavy landing and the cause of risk. The present invention utilizes the characteristic parameters of certain time points or time periods of the Measurement data, and simultaneously considers the extent to which the characteristics deviate from the normal range to construct a heavy landing risk assessment model, which is convenient for airlines to understand the degree of flight heavy landing risk and explore its risk causes. On this basis, the present invention implements its system to facilitate the management and automatic evaluation of massive flight data, and can also display valuable information such as risk change trends through visualization.
[0088] The invention provides a method for monitoring and evaluating flight and landing quality, such as Fig...

The invention provides a flight landing quality monitoring and evaluating method and system, and belongs to the field of data mining, aviation safety and risk evaluation. According to the method, a Measurement index related to heavy landing is obtained by using original QAR data of an airplane, and a heavy landing risk value is obtained by using the Measurement index. The method comprises the following steps: (1) collecting original QAR data of an aircraft; (2) extracting a flight parameter measurement value, namely, Measurement data, from the original QAR data; (3) preprocessing the data; and (4) constructing a heavy landing risk assessment model to obtain a heavy landing risk value. By means of the flight re-landing risk assessment system and method, an airline company can know the flight re-landing risk degree and explore the risk reason of the flight re-landing risk degree, mass flight data management and automatic assessment can be achieved conveniently, and valuable information such as the risk change trend can be displayed visually.
Description
technical field [0001] The invention belongs to the fields of data mining, aviation safety and risk assessment, and in particular relates to a method and system for monitoring and evaluating flight and landing quality. Background technique [0002] In a modern society where the aviation industry is well developed, aviation safety has always been one of the most important topics in the aviation field. According to Boeing's statistics on major flight safety accident data from 2009 to 2019, the final landing stage is a stage that is very prone to flight safety accidents. The main reason is that the aircraft requires a large number of pilot operations and complex environmental changes at this stage. Misjudgment or improper operation of the pilot may lead to serious consequences, such as triggering safety incidents. Therefore, it is of great significance to the field of aviation safety to study and analyze the landing phase. [0003] Among landing safety events, hard landing is...
