Offset Calculation for Traffic Scenarios

Abstract

The integration of unmanned aerial systems (UAS) and remotely piloted aerial systems (RPAS) will play a key-role in the world-wide aviation for the next years. One of the major challenges is to carry out proper detect-and-avoid (DAA) with such vehicles, even in the presence of manned aircraft. To ensure a safe detection one possibility is to equip the vehicle with active sensors that can sense surrounding traffic. To evaluate the level of safety an understanding for minimal detection ranges of such systems has to be established. This paper presents a number of traffic scenarios that cover most cases encountered in practice. Thus, the simulation scenarios constructed from these principles can be used to determine minimal sensor detection ranges that a real-world system has to adhere to in order to be considered safe in mixed-traffic operations. Specifically, we address the problem of constructing scenarios that do not trigger TCAS alerts but can be used to evaluate DAA algorithms.
