| 广播式自动相关空空监视(Automatic Dependent Surveillance-Broadcast IN,ADS-B IN应用能够在飞行活动中为飞行员提供诸多便利，而安全性是实现ADS-B IN应用优势的前提。针对ADS-B IN应用在实际飞行活动中可能存在的安全性问题，引入了一种基于Bow-tie模型的安全评估方法。该方法通过对预设危险进行分析，得出危险发生的最大可接受概率，进而推导出为实现这一概率所需的ADS-B设备失效率或通信数据链路完整性等安全要求。在对该方法进行阐述的基础上，给出了一个具体实施案例，对该方法做进一步说明。 |

| Abstract: |
| Automatic Dependent Surveillance-Broadcast IN(ADS-B IN applications can provide numerous conveniences for pilots during flight operations,with safety being the prerequisite for realizing the advantages of ADS-B IN applications.A Bow-tie model-based safety assessment method is introduced to address potential safety issues associated with ADS-B IN applications in actual flight activities.By analyzing pre-defined hazards,the maximum acceptable probability of hazard occurrence is determined,which in turn leads to the derivation of safety requirements such as the failure rate of ADS-B equipment or the integrity of communication data links necessary to achieve this probability.Based on the explanation of this method,a specific implementation case is presented to further illustrate its application. |
