Brazilian drone regulations reached their maturity point in 2026. With the issuance of Design Authorizations for autonomous systems, flying BVLOS (Beyond Visual Line of Sight) has evolved from a scientific experiment into an operational mandate for large Energy, Logistics, and Security companies.
However, when the Director of Operations presents an autonomous fleet project for approval, they hit the ultimate barrier: the Legal and Compliance Department.
Compliance’s questions are direct and relentless: “What happens if there is a communication failure with the drone 10 km away? What is the probability of hitting a person or a manned aircraft? Does our insurance policy cover this operation?”
The only way to answer these questions—and to secure approval from ANAC (National Civil Aviation Agency) and DECEA (Department of Airspace Control) to fly BVLOS—is through a structured risk analysis. This is where the SORA Methodology comes in.
In this article, Horus explains, in simplified terms, what SORA is and how our Regulatory Consulting delivers this intelligence fully prepared so that your legal department can approve the operation with absolute confidence.
What is the SORA Methodology?
SORA stands for Specific Operations Risk Assessment. Developed by JARUS (an international group of aviation authorities) and fully adopted by ANAC in Brazil, SORA is not a physical test the drone undergoes; it is a highly analytical safety and operations engineering process.
The methodology is based on a simple principle: instead of creating rigid, blanket rules for every drone in the world, the agency evaluates the risk of your specific operation. Flying a 10 kg drone over the ocean carries a vastly different risk profile than flying that exact same drone over a mining site.
SORA divides risk into two primary mathematical categories:
- GRC (Ground Risk Class): What is the probability of your drone crashing and hitting an uninvolved person on the ground? This calculation factors in the drone’s weight, wingspan, and the population density of the overflown area.
- ARC (Air Risk Class): What is the probability of your drone breaching the airspace of a manned airplane or helicopter? This calculation accounts for flight altitude, proximity to airports, and airspace utilization (controlled vs. uncontrolled).
The Operational Nightmare: Why Doing It In-House Doesn’t Work
To approve a BVLOS flight, the operator must submit an extensive dossier to ANAC proving that the operation’s GRC and ARC are acceptable, and that they have solid mitigation barriers in place (known as SAIL – Specific Assurance and Integrity Level).
The problem is that building a SORA dossier from scratch requires drafting a highly detailed ConOps (Concept of Operations), contingency manuals, redundancy tests, and airspace mapping.
When a company’s O&M (Operations & Maintenance) or Innovation department attempts to tackle SORA internally, the process can drag on for months or even years. Without the correct aeronautical jargon and a deep understanding of regulatory nuances, the application suffers dozens of kickbacks and demands from regulatory bodies. The hardware sits in the box, and the ROI evaporates.
How Horus Simplifies and Solves SORA
At Horus Smart Detections, we understand that your company doesn’t need to become an expert in aviation law. Your company needs data and efficiency.
Our Regulatory Consulting arm lifts the burden off your legal department by delivering the SORA package structured across three main pillars:
Pillar 1: The Authorized Hardware “Bypass”
The first major step of SORA is proving the aircraft is reliable. Because Horus is an Official DJI Enterprise Reseller, we work with equipment that already holds Design Authorization from ANAC (such as the Matrice 3D line and the DJI Dock 2). This means manufacturing safety and redundancies (dual IMUs, parachutes, anti-collision beacons) are already validated, cutting SORA bureaucracy in half.
Pillar 2: The “Ready-to-Wear” ConOps
Instead of having your team stare at blank pages, our consulting team delivers a Concept of Operations (ConOps) precisely tailored to your vertical. We map out:
- Exact flight routes and airspace classification (SARPAS/DECEA).
- Standard Operating Procedures (Checklists).
- Emergency Response Plan (ERP): We document exactly what the drone’s Artificial Intelligence will do in the event of a GPS signal loss, C2 (Command and Control) data link loss, or the approach of a manned aircraft.
Pillar 3: Tactical and Strategic Risk Mitigations
To reduce the GRC and ARC of your operation, we design and prove the mitigation barriers to ANAC. This includes:
- Strategic Mitigation: Restricting flights to times of low air traffic or designing buffer zones (geofencing) around the operational area.
- Tactical Mitigation: The use of onboard detect-and-avoid sensors (ADS-B receivers and omnidirectional obstacle radars) that ensure airspace safety far beyond the human visual line of sight.
The Result: Legal Certainty to Scale
By implementing the Horus ecosystem, your Compliance department doesn’t just receive a promise that “the drone is safe.” They receive documentary evidence, approved by federal aviation authorities (ANAC and DECEA), attesting to the operation’s robustness.
Approving BVLOS flights via the SORA methodology with Horus’s advisory acts as a governance shield. It protects the company’s C-suite against operational liabilities, enables the procurement of insurance policies with lower premiums, and unlocks the use of autonomous technology on a massive scale.
Leave regulatory complexity in the hands of experts.
