“…Previous studies have looked at DAA system requirements for larger UAS operating in en-route and terminal environments (Fern et al, 2018;Rorie et al, 2017;Rorie et al, 2019). More recently, DAA research has focused on developing Minimum Operational Performance Standards (MOPS) for a broader range of UAS types, including smaller UAS that will need onboard sensors classified as low in size, weight, and power (SWaP) (RTCA, 2019).…”

Currently, minimum operational performance standards (MOPS) are being developed for a broader rangeof unmanned aircraft system (UAS) platforms, including smaller UAS that will feature onboard sensors that are low in size, weight, and power, otherwise known as low SWaP. The low SWaP sensors used to detect non-cooperative traffic will have limited declaration ranges compared to those designed for medium-to-large UAS. A human-in-the-loop (HITL) study was conducted examining four possible radar declaration ranges (i.e., 1.5 NM, 2 NM, 2.5 NM, and 3 NM) for a potential low SWaP sensor with a detect and avoid (DAA) system encountering various non-cooperative encounters in Oakland Center airspace. Participants had lower workload, particularly workload associated with temporal demand and effort, in scenarios that featured larger detection ranges. Furthermore, participants reported better ability to remain DAA well clear within the larger declaration range conditions, specifically with the 2.5 NM and 3 NM conditions.
