If you’re in the drone world, you’ve likely heard the term SORA risk analysis mentioned in regulation and compliance circles. SORA stands for Specific Operations Risk Assessment.
It is a structured method developed by EASA (the European Union Aviation Safety Agency) for analyzing drone flight risks, especially for operations that fall outside the basic or “open” category.
Drone risk assessment is no longer a “nice to have.” As more UAVs operate in cities, near people, or close to restricted airspace, regulators demand greater accountability for every flight.
EASA SORA provides a standard, science-backed way for drone operators to prove they can mitigate hazards and protect the public, infrastructure, and airspace.
Without a robust SORA process for drones, operators would struggle with inconsistent rules, unclear responsibilities, and legal grey zones.
Implementing SORA builds confidence for clients, pilots, and the wider community that commercial drone activities take safety and compliance seriously, not as an afterthought.
For every drone operation, especially in EASA-regulated regions, SORA risk analysis shapes what’s possible before a drone ever lifts off. The process helps decide:
This means SORA risk analysis doesn’t just affect compliance paperwork. It actually steers how drones can be used in real commercial and public missions, from mapping to delivery or inspections.
While SORA drones rely on a formal EASA SORA process, its structure can be broken down into manageable parts:
First, the operator clearly defines the mission. This means mapping out what drone will be used, where it will fly, what it will do, and who will be in control. No details are skipped. The more exact the description, the smoother the later steps.
This part looks at what happens if something goes wrong and the drone comes down uncontrolled. The process considers who or what could be at risk people, property, moving vehicles and assigns a risk level. For higher-risk sites like cities, expect stricter controls.
SORA drills into aerial danger next. How likely is the drone to collide with manned aircraft or other drones? Are there airports, hospitals, or known aviation routes close by? Operators look at airspace class and possible conflicts and pick mitigation strategies.
SAIL is a score calculated as part of the SORA process for drones. It represents the risk level tied to an operation, combining both ground and air hazards. Higher SAIL values demand more safety features, redundancies, and operational safeguards.
Any proposed mitigation has to be justified. Regulators want evidence that safety steps are proven and dependable, not just nice ideas. This can mean referencing industry standards, conducting real-life demonstrations, or pulling from safety case studies.
Let’s look at a drone operator planning a medical delivery flight over a busy urban area.
Let’s look at a drone operator planning a medical delivery flight over a busy urban area.
1. Start with a detailed operation description: The operator defines the flight plan, the drone specs, pilot credentials, and the delivery drop-off and pickup zones.
2. Ground risk assessment: Since the city is full of people, the SORA ground risk scoring is high. Plans might include choosing less dense routes, scheduling at quieter times, or limiting cargo weight.
3. Air risk assessment: The airspace has low-flying helicopters and is near a hospital. The operator investigates where conflicts might arise and whether coordination with air traffic is needed.
4. Mitigation: Plans include extra pilot training, backup comms, flight path monitoring, and use of “return to home” tech if signal is lost.
5. SAIL calculation: Based on these risks, the SORA process for drones produces a SAIL number. Higher SAIL often requires more technical mitigations such as parachutes or automatic collision avoidance.
6. Implementation and review: Operator documents all mitigation steps with evidence, runs simulations, and addresses regulator feedback.
7. Approval: If the SORA risk analysis satisfies all criteria, the commercial drone delivery may get the green light.
In another example, a mapping company runs SORA for flight above farm fields. Lower population density means lower ground risk, simplifying mitigation and paperwork needed for regulatory approval.
As the global drone industry adopts stricter operational and safety standards, compliance with frameworks like SORA (Specific Operations Risk Assessment) has become essential for manufacturers, operators, and service providers.
BeyondSky, the world’s first B2B marketplace for the global drone industry, helps businesses align with these evolving regulations through:
SORA-Ready Equipment: Verified UAVs, payloads, and control systems that meet EASA and BVLOS safety standards.

As new commercial drone applications grow, so does the importance of mastering the SORA process for drones. The EASA SORA method isn’t just about ticking boxes. It’s about laying a strong foundation so that every flight, inspection, or delivery has safety built in from the start.
For operators, clients, and regulators, well-done specific operations risk assessment is the difference between grounded ambitions and drones earning their place as trusted tools in the modern world.
SORA stands for Specific Operations Risk Assessment. It’s a structured drone risk assessment method by EASA for analyzing hazards in commercial drone flights beyond basic operation categories.
As drones fly closer to people and sensitive sites, safety demands rise. SORA helps drone operators prove they can mitigate risks and protect the public, airspace, and infrastructure reliably.
The process includes defining the mission, assessing ground and air risks, calculating the Specific Assurance and Integrity Level (SAIL), verifying mitigation robustness, and securing approvals.
SAIL quantifies the risk level of an operation. Higher SAIL scores require stronger safety measures, like parachutes or automated collision avoidance systems.
SORA guides what approvals are needed, pilot qualifications, equipment specs, flight zones, and stakeholder involvement before drones can fly specific commercial or public missions.
A medical drone delivery over a city undergoes SORA by evaluating risks, selecting safe routes, pilot training, backup systems, and finally obtaining regulatory approval based on achieving safety objectives.
SORA 2.5 adds clearer ground risk assessment methods, supports autonomous drone risks, and streamlines procedures to enhance practical use across diverse operations.
