Abstract

Near Mid-Air Collision (NMAC) risk is an impediment to the integration of Unmanned Aircraft System (UAS) into non-segregated airspace. It is quantified by a NMAC rate per flight hour, and this rate has been used for risk assessment for manned aviation. To estimate similar statistics with the inclusion of UAS in a known airspace, MIT Lincoln Laboratory (MIT/LL) has built an UAS-centric encounter model of the US National Airspace System (NAS). This thesis builds upon the MIT/LL encounter model to estimate a Canadian NMAC rate using on a standard proposed by National Research Council of Canada. The reported assessment takes into the account of the variation of field of view, radar range used for detection and tracking of the Intruder and the UAS achievable horizontal turn rate. Depending on the traffic, a notional radar-based detect-and-avoidance system could be demonstrated to have a lower NMAC rate than the Canadian NMAC rate.
