About SORA (Specific Operations Risk Assessment for Drones)

This event covers the compliance, engineering, and verification requirements defined by SORA.

SORA is JARUS's risk assessment methodology for UAS specific-category operations, adopted by EASA: it derives ground and air risk classes for a concept of operations, applies mitigations, and yields a SAIL level dictating operational safety objectives (OSOs).

What it regulates

The ten-step process: ConOps definition, intrinsic ground/air risk (GRC/ARC), strategic and tactical mitigations, SAIL determination, OSO robustness levels, containment requirements, and adjacent-area considerations.

Who must comply

Drone operators seeking specific-category authorizations (BVLOS delivery, inspection) and NAAs assessing them.

Key requirements of SORA

  • GRC from operation footprint over people; ARC from airspace encounter risk
  • Mitigations: sheltering, parachutes, DAA, airspace measures with robustness evidence
  • SAIL I-VI mapping to OSO requirement sets
  • Containment (flight geography, contingency, buffer) design

Key concepts: SORA

Containment
Assurance the aircraft stays within approved volumes even under failure.
OSO
Operational Safety Objectives — the requirement checklist whose required robustness scales with SAIL.
SAIL
Specific Assurance and Integrity Level — the operation's overall demand level on people, procedures and tech.
Tactical vs strategic mitigation
Real-time (detect and avoid) versus pre-planned (airspace, timing) risk reductions.

Frequently asked questions: SORA

How does SORA connect to design standards?

Higher SAIL pushes OSOs toward certified-grade evidence for the aircraft and its functions (e.g., containment integrity), pulling in design assurance practices (DO-178C-style software rigor) proportionate to operational risk.
