The invention provides a test flight scene hazard source identification system, method and device and electronic equipment. Comprising the following steps: S101, classifying a test flight scene based on a shell model to obtain a plurality of factors; s102, analyzing the factor through a shell model, and determining a credible interval to which the factor belongs; and S103, performing assignment on each factor through the multivariate discrete model, and performing principal component regression analysis according to the credible interval to which the factor belongs so as to identify the hazard source. According to the identification method, the problem that the dangerous source in the test flight scene cannot be reliably identified in the prior art is solved.
Description
technical field [0001] The invention relates to the technical field of civil transport aircraft, in particular to a system, method, device and electronic equipment for identifying hazards in a flight test scene. Background technique [0002] According to the definition of ICAO standard, hazard refers to the situation or object that may cause an aircraft accident or incident (Doc9859). At present, the risk management in the civil aviation transportation industry mostly focuses on the risk assessment of hazards, mainly using two risk matrix models: the operating condition hazard evaluation method (LEC) and the risk matrix method (LS). The identification of hazards mainly relies on subjective methods such as brainstorming method or fault tree method. The applicable scenarios and scope of these methods are based on the results of reverse deduction. It is an active evaluation process, and most of the evaluation elements are impossible. Quantitative and subjective factors are inv...
