SAFETY ASSESSMENT & CERTIFICATION FOR UAS

As part of the certification process to gain clearance to operate in unsegregated airspace, new UASs will require a robust Safety Assessment process. The authors have looked at the civil manned aircraft safety assessment process defined in ARP 4761 and the safety certification process in ARP4754, as used to demonstrate compliance with EASA / FAA safety target requirements, in order to develop a UAS-applicable process. The paper looks at the background to UAS safety assessment, in particular why UAS need a structured Safety Assessment process in order to gain access to unsegregated airspace. It then goes on to propose a ‘UAS-friendly ’ safety assessment process, and particularly, UAS hazard identification using a revised Functional Failure Analysis (FFA) method.
