Introduction: The Rise of UAS and SORA Compliance
The Unmanned Aircraft System (UAS) sector is soaring, with projections estimating a $63 billion contribution to the global economy by 2025, according to IATA.
From delivery drones to urban air mobility, UAS operations are reshaping aviation. However, advanced operations like Beyond Visual Line of Sight (BVLOS), Operations Over People (OOP), or fleet missions carry significant risks, necessitating rigorous safety frameworks.
The Specific Operations Risk Assessment (SORA), developed by JARUS and adopted by the European Union Aviation Safety Agency as an Acceptable Means of Compliance (AMC) for Regulation (EU) 2019/947, provides a structured 10-step methodology to assess and mitigate these risks, ensuring safety levels align with ICAO Annex 19 standards.
For aviation safety managers, professionals, and accountable executives, SORA compliance is essential to secure operational authorizations from National Aviation Authorities (NAAs) and maintain safety. SMS Pro’s aviation SMS software simplifies this complex process with tools like offline risk assessments, centralized data management, automated workflows, and training modules. This article offers a comprehensive guide to mastering SORA compliance, detailing each step, addressing challenges, and showcasing how SMS Pro enhances efficiency for UAS operators, including airlines, MROs, and eVTOL pioneers.
Understanding SORA: A Risk-Based Approach
SORA is a risk assessment framework for UAS operations in the Specific Category, covering missions too complex for the Open Category (low-risk) or requiring certification in the Certified Category (high-risk). It classifies risks into Ground Risk Class (GRC) and Air Risk Class (ARC), determining a Specific Assurance and Integrity Level (SAIL) from I (low risk) to VI (high risk). Higher SAILs demand robust mitigations, such as certified systems or design verification reports (DVRs). SORA’s 24 Operational Safety Objectives (OSOs) scale with SAIL, covering training, maintenance, and procedures.
Key SORA components include: - **Ground Risk Class (GRC)**: Risk of striking people or property, based on drone size, energy, and environment (e.g., urban vs. rural). - **Air Risk Class (ARC)**: Risk of mid-air collisions, ranging from ARC-A (remote airspace) to ARC-D (near airports). - **Concept of Operations (ConOps)**: A detailed plan outlining the UAS, mission, and mitigations. - **SAIL and OSOs**: Risk level and corresponding safety requirements.
SORA’s complexity can overwhelm operators, but SMS Pro’s Part 5 Fulfillment module streamlines compliance, as explored in hazard identification strategies.
Step 1: Develop a Detailed ConOps
The ConOps is SORA’s foundation, detailing the UAS, mission, operational environment, crew training, and emergency procedures. A robust ConOps ensures accurate risk assessment, but incomplete plans lead to 30% of NAA rejections (EASA data). SMS Pro’s Policy Manager and custom reporting forms facilitate ConOps development, capturing specifications like drone weight, flight paths, and contingency plans (e.g., lost link procedures).
For a BVLOS delivery operation, the ConOps might include airspace restrictions and crew qualifications. SMS Pro’s centralized database ensures all data is accessible, reducing documentation errors by 20%. Safety managers must align the ConOps with operational realities to avoid delays.
- Action: Document the ConOps in SMS Pro’s Policy Manager, integrating with reporting forms.
- Tip: Include detailed emergency procedures to lower SAIL, cutting approval time by 15%.
A thorough ConOps sets the stage for SORA compliance.
Step 2: Assess Ground Risk (GRC)
GRC evaluates the risk of a drone striking people or property, determined by factors like drone size, kinetic energy, and operational area. Urban OOP missions yield higher GRC than rural operations. SMS Pro’s offline FRAT enables real-time GRC assessments, logging data like population density and flight altitude. Initial GRC is adjusted with mitigations, but inaccurate assessments inflate SAIL, increasing costs by 25% (EASA data).
For an eVTOL urban operation, SMS Pro’s Risk Management System captures ground risks, syncing with the Hazards Register. Safety managers must consider worst-case scenarios, such as drone failure over a crowd.
- Action: Conduct GRC assessments using SMS Pro’s FRAT, syncing to the Hazards Register.
- Tip: Document population data to reduce GRC misclassification by 10%.
Precise GRC assessment minimizes ground-related risks.
Step 3: Implement Ground Risk Mitigations
Mitigations reduce GRC by lowering impact probability or severity. Examples include parachutes, buffer zones, or enhanced crew training. SMS Pro’s LMS delivers competency-based training, a key OSO, while risk analysis charts visualize mitigation effectiveness. For a delivery drone, geofencing restricts flights over populated areas, lowering GRC. Weak mitigations risk 20% higher SAILs, per EASA data.
SMS Pro’s automated workflows track mitigation implementation, ensuring accountability. Safety managers must validate mitigations with real-world data, such as test flights, to meet NAA requirements.
- Action: Train crews on mitigations using SMS Pro’s LMS, logging completion for audits.
- Tip: Use M1 mitigations (e.g., emergency response plans) to lower GRC by one level.
Effective mitigations streamline SORA approvals.
Step 4: Determine Air Risk (ARC)
ARC assesses the risk of mid-air collisions, classified from ARC-A (low, remote airspace) to ARC-D (high, near airports). BVLOS operations near urban airports often yield ARC-D, requiring robust mitigations. SMS Pro’s hazard reporting tools capture airspace data, ensuring accurate ARC classification. Misclassification, as noted by the European Cockpit Association, delays approvals by 25%.
For a UAS surveying near an airport, SMS Pro’s Hazards Register logs air traffic risks, integrating with the ConOps. Safety managers must analyze airspace density and manned aircraft activity.
- Action: Log airspace risks in SMS Pro’s hazard reporting system, linking to ConOps.
- Tip: Coordinate with air traffic control to lower ARC, reducing SAIL by 10%.
Accurate ARC determination prevents operational delays.
Step 5: Apply Air Risk Mitigations
Air risk mitigations, such as detect-and-avoid systems, altitude limits, or transponders, reduce ARC. SMS Pro’s automated notifications alert operators to airspace changes, ensuring compliance with tactical mitigations. For BVLOS operations, M2 mitigations like collision avoidance systems are critical. Inadequate mitigations risk 20% higher SAILs, per EASA data.
SMS Pro’s risk analysis charts evaluate mitigation performance, ensuring NAA acceptance. Safety managers must document mitigation details, such as system specifications, in the ConOps.
- Action: Set SMS Pro’s notifications for airspace updates, supporting M2 mitigations.
- Tip: Test mitigation systems in simulations to reduce NAA revisions by 15%.
Robust air risk mitigations enhance compliance.
Step 6: Assign Specific Assurance and Integrity Level (SAIL)
SAIL combines mitigated GRC and ARC, ranging from I (low risk) to VI (high risk). Higher SAILs require stringent OSOs, such as EASA-certified systems or DVRs. SMS Pro’s risk analysis charts dynamically calculate SAIL, ensuring accuracy. Misjudging SAIL increases compliance costs by 30% (EASA data).
For an eVTOL operation, a high GRC and ARC-D might yield SAIL V, requiring certified sensors. SMS Pro’s tools align SAIL with operational data, reducing errors.
- Action: Compute SAIL using SMS Pro’s risk analysis charts, validating with data.
- Tip: Pre-submit SAIL calculations to the NAA to avoid 20% of rejections.
Accurate SAIL assignment accelerates approvals.
Step 7: Define Operational Safety Objectives (OSOs)
SORA’s 24 OSOs cover training, maintenance, procedures, and system integrity, scaled by SAIL. For SAIL V–VI, OSOs demand EASA oversight or certified components. SMS Pro’s LMS ensures training compliance, while maintenance tracking verifies system integrity. For a BVLOS operation, OSOs include pilot certification and regular sensor checks.
