摘要：	Remotely Piloted Aircraft (RPA) for cargo operations in the national airspace system willimpact safety due to, among other factors, the latency and reliability of command & control,and of communication. This paper investigates the safety impact with increasing mix of RPAamidst manned traffic in a generic arrival pattern with three merging flows. Latency wasmodelled as the response time between air traffic control’s determination of a resolution andthe RPAs’ initiation of the maneuver. Reliability was modelled as a message drop probability.The experiment was repeated with two different aircraft types having different performancecharacteristics as representatives of RPA for conducting automated cargo operations. Overallresponse time above thirty seconds and message drop probability over twenty percent causedlosses of separation. Specific results depended on the RPA aircraft type. The detailed impactsof latency and reliability with increasing mix of RPA traffic are provided. Applications of theapproach for further studies at increasing levels of automation are also discussed.
