本文介绍了一种方法，用于确定需要达到何种整体系统可靠性才能满足美国联邦航空管理局 (FAA) 的安全要求。国防部飞行试验场开发了一种偶然预期方法，用于计算伤亡概率。该方法利用人口密度、平台大小、系统可靠性等来计算在发生灾难性飞行故障时的预期伤亡率。这些信息用于规划无人机的飞行路径，以避免人员伤亡。通过将其与通用航空联邦航空要求 (FAR 23) 经验进行比较，并确定无人机的等效安全水平，该方法得到扩展，以确定 FAA 空域的等效安全性。该分析的结果用于确定所需的系统级安全要求，作为无人机 (UAV) 平台尺寸的函数。适航监管机构可以使用这些数据作为确定各类无人机安全认证级别的基础。
This paper describes a methodology for determining what overall system reliability is required to be equivalent to Federal Aviation Administration (FAA) safety requirements. Department of Defense flight test ranges have developed a casual expectation methodology used to calculate the probability of casualty. The methodology uses population density, platform size, system reliability, etc. to calculate the expected casualty rate given a catastrophic in-flight failure. This information is used to plan the flight paths of Unmanned Aerospace Vehicles to avoid casualties. This methodology was expanded to determine equivalent safety for FAA airspace by comparing it to general aviation Federal Aviation Requirements (FAR 23) experience and determining an equivalent level of safety for unmanned aircraft. The results of this analysis were used to determine the required system level safety requirements as a function of Unmanned Aerospace Vehicle (UAV) platform size. Airworthiness regulation authorities can use this data as a basis for determining certification levels of safety for various classes of UAVs.
