For many years, safety for unmanned aircraft systems has been a central topic in discussions held by the industry’s stakeholders. The fact that the approach has to be different than the one applied for manned aircraft but still needs to guarantee a similar level of safety makes the situation particularly challenging and complex to address.
Certification authorities have a common objective to define rules that guarantee the safety of UAV operations without preventing the development of the industry sector by blocking new applications. In this context, JARUS (the Joint Authorities for Rulemaking on Unmanned Systems) developed a methodology called SORA which provides UAS operators with a solution to assess the risk of their operations and apply for authorization. SORA stands for Specific Operations Risk Assessment and allows for systematically identifying the risk of complex UAV operations within the specific category. The aim of this process is to guide the applicant and the competent authorities on their path to determine in detail the planned operation and the risks involved with it, all in the perspective of defining the required mitigation measures and conducting safe operations. The methodology is focused on assigning two classes of risk to a UAS operation (a ground risk class (GRC) and an air risk class (ARC)) and providing the operator with mitigation measures to potentially reduce them. These risk classes form the basis for the next steps which consist of determining the level of confidence that the UAS operation will stay within its boundaries. The efficiency of this methodology allowed the SORA to be endorsed by EASA, the European Union Aviation Safety Agency, as an Acceptable Means of Compliance (AMC) to fulfill the requirements of the European UAS Regulations.
The 10 steps of SORA
The SORA represents an iterative process of 10 steps that are the following:
Specific guidance material (GM) was created to carefully guide users through these steps. This guidance material aims to simplify the process but is not always sufficient to support the applicant depending on their knowledge and background. If further guidance is needed, applicants have the possibility to reach out to companies such as consulting firms, which specialize in helping them deal with their applications.
