We are pleased to announce the publication of ED-336 “Guidelines for SAIL II application of SORA”.

ED-336 defines Guidelines for SAIL II application of SORA. The Specific Operations Risk Assessment (SORA) methodology stands as a robust framework to evaluate the risk associated with Unmanned Aircraft Systems (UAS) operations within the Specific category. Built upon a proportionate approach, SORA mandates that the robustness of an operation be commensurate with the assessed level of risk.

Within this framework, operations are classified into different risk levels, ranging from Specific Assurance and Integrity Levels (SAIL) I to VI, each demanding tailored safety measures and regulatory adherence. For low-risk operations (SAIL I and SAIL II), safety is predominantly ensured during the planning phase and through the implementation of adequate operational procedures. The primary goal of this document is to provide guidelines for all Operational Safety Objectives (OSO) in SAIL II operations, that will assist applicants in enhancing the quality of their submissions to National Aviation Authorities (NAA), therefore streamlining the UAS authorization process and alleviating the burden on regulatory divisions.

A huge thank you to the dedicated members of WG-105 for their invaluable work!
