Abstract

In the document of the Radio Technical Commission for Aeronautics (RTCA) [1], a methodology has been developed for the flight safety level assessment when using a promising automatic dependent surveillance system in broadcast mode (ADS-B) intended for certification of an air traffic control system. As the analysis presented in the article has shown, this technique is based on an erroneous hypothesis, the use of which leads to underestimated requirements for the ADS-B certified system. The example considered in the article shows that the rejection of this erroneous hypothesis can lead to tightening the requirements by an order of magnitude. To obtain correct results, the article proposes an easy-to-compute modification of the technique that is devoid of this, generally speaking, serious drawback. The use of the proposed technique is illustrated by an example.

使用 ADS-B 修改空中交通服务中的安全等级评估方法

摘要

在航空无线电技术委员会 (RTCA) [1] 的文件中，已经开发了一种飞行安全水平评估方法，该方法使用有前途的广播模式自动相关监视系统 (ADS-B)交通管制系统。正如文章中的分析所示，这种技术基于错误的假设，使用该假设会导致对 ADS-B 认证系统的要求被低估。文章中考虑的例子表明，拒绝这个错误的假设会导致要求严格一个数量级。为了获得正确的结果，该文章提出了一种易于计算的技术修改方案，该修改方案没有这个一般来说的严重缺陷。
