介绍了功能共振理论,说明了事故发生机理,描述了功能单位,介绍了一般性能条件和功能性能波动状态,以及功能共振事故模型分析步骤。利用功能共振事故模型对可控飞行撞地事故进行了分析,识别描述了功能单位,建立了功能网络;根据一般性能条件评价了各个功能单位性能波动状态,在评价结果基础上分析了各个功能单位性能波动状态,确定了“管制员发出下降指令”和“输入导航点信息”两个随机状态功能单位;进一步分析了功能共振和失效功能连接,以及影响功能共振的功能因素,建立了功能共振失效网络,确定了“管制员发出下降指令”、“输入导航点信息”、“保持下降航路”、“到达指定导航点”四个功能共振单位;最后识别出了波动障碍,并制定了“调整飞行管理系统导航点信息显示方式”等多个性能监测措施管理可控飞行撞地功能性能波动。
The theory of functional resonance is introduced, the mechanism of accident is described, the functional unit is described, the general performance conditions and the fluctuation state of functional performance are introduced, and the analysis steps of functional resonance model are introduced. The functional resonance accident model was used to analyze the accident of controllable flight collision. The functional units were identified and the functional networks were established. The performance status of each functional unit was evaluated based on the general performance conditions. Based on the evaluation results, the functional units Performance fluctuation state, two “stochastic state function units” such as “controller sends down instruction” and “input navigation point information” are determined; functional resonance and failure function connection are further analyzed, and functional factors that affect resonance of function are established; Function resonance failure network, identified the “controller issued a descent command ”, “input navigation point information ”, “keep the descent route ”, “to reach the designated navigation point ” four functional resonance units; finally Identified the fluctuation obstacle, and formulated “the performance of the flight management system navigation point information display” and other performance monitoring measures to control the performance of controlled flight hit the ground.
