MoC → OSO Index
Means of Compliance documents mapped to SORA Operation Safety Objectives (OSOs) for the EASA UAS specific category, SAIL III. All six MoCs in this corpus are Final, issued 19 December 2024 (OSO#19/#20 dated 21 July 2024) by the UAS TeB Airworthiness Task Force (EASA + AESA + Austro Control + DAC Luxembourg + DGAC + ENAC + FOCA + HCAA + Irish Aviation Authority + LBA + CAA Latvia/Norway/Romania/Estonia/Slovenia/Netherlands).
The MoCs target UAS designers (the "applicant"), who issue a signed declaration of compliance to operators applying for operational authorisation.

| 05 | System Safety and Reliability | Low | MOC OSO #05-01 | OSO-05 — System Safety and Reliability |
| 06 | C2 Link (C3 characteristics) | SAIL III | MOC to OSO#06-01 | OSO-06 — C2 Link |
| 18 | Auto-protection of flight envelope from human errors | Low | MOC OSO #18-01 | OSO-18 — Automatic Protection of Flight Envelope from Human Errors |
| 19 / 20 | Safe Recovery from Human Error & HMI | Low | MOC to OSO#19/#20-01 | OSO-19-20 — Safe Recovery from Human Error & HMI |

Cross-OSO dependencies (as called out by these MoCs)
- OSO#01 → recurrent malfunction methodologies referenced from OSO#03
- OSO#05 ← input to OSO#06 (C2 HW/SW), OSO#18 (auto function safety), OSO#24 (which systems need env qualification)
- OSO#08 → operational procedures incl. pre-/post-flight inspections (out of scope of OSO#03)
- OSO#09 → remote crew training (input to OSO#19/20)
- OSO#13 → external comm services SLA (referenced from OSO#06 and OSO#05)
- OSO#16 → multi-crew coordination (input to OSO#19/20)
- OSO#17 → remote crew fitness (input to OSO#19/20)
- OSO#18 ↔ OSO#19/20 — envelope protection assessed in #18; other human-error recovery and HMI in #19/20
- OSO#23 → operator must stay within env envelope set by OSO#24
- OSO#24 ← uses OSO#05 output for system selection; feeds OSO#06 functional performance
