对功能危险性进行评估是安全性评估中最重要的一步,并且还具有不容忽视的作用。文章对系统功能的实际危险性评估的步骤以及目的进行了介绍,然后把针对自动飞行这个控制系统的评估过程做了详细介绍,望民用飞机系统能够将此作为评估系统功能安全性的依据。
Assessing functional hazards is one of the most important steps in safety assessment and can not be ignored. This paper introduces the procedure and the purpose of the actual risk assessment of system functions, and then introduces the evaluation process of the control system for automatic flight in detail. It is expected that the civil aircraft system can serve as the basis for evaluating the functional safety of the system.
