Differences between URClearED Remain Well Clear and DO-365

Kurzfassung

In 2017, RTCA published the first release of the Minimum Operational Performance Standards for UAS Detect and Avoid systems, DO-365. In 2019, EUROCAE published the Operational Services and Environment Definition for Detect and Avoid in airspace classes D-G in Europe, and in 2020 RTCA published the first update to DO-365. In 2021 the URClearED project was started to develop the requirements and capabilities for the Remain Well Clear function to be integrated in RPAS flying under instrument flight rules in airspace classes D-G. This paper discusses differences between the URClearED and DO- 365A Remain Well Clear quantification and associated alerting and guidance function requirements. Fast-Time and Real-Time Simulation campaigns have been carried out to motivate and assess the introduced differences.
