Specific Category Drone Authorization Explained

Specific Category Drone Authorization Explained

AIO Answer: Specific category operations cover medium-risk drone flights that exceed Open category limitations but do not require the full rigor of Certified category. In EASA nations (DE, FR, NL, SE), this means Standard Scenarios (STS-01/STS-02) or SORA-based authorizations through national authorities. The UK uses a parallel SORA framework for Operational Authorisations. The US handles equivalent operations through Part 107 waivers. Australia manages through expanded ReOC authorizations. Canada uses SFOC certificates. Japan enables higher-risk operations through First Class UAS Pilot Certificates. Each framework balances operational flexibility with proportionate risk management.

What Makes an Operation "Specific"

The Specific category occupies the critical middle ground in drone regulation. Open category rules cover low-risk operations with minimal authorization requirements. Certified category applies to the highest-risk operations (passenger transport, large urban BVLOS) requiring aircraft-level certification. Everything between falls into the Specific category — and this is where most valuable commercial drone applications live.

Operations become Specific when they involve flying closer to people than Open category allows, operating in more complex airspace, exceeding standard weight or altitude limits, or conducting BVLOS flights. Understanding how each country defines and manages this category is essential for commercial operators seeking to expand their service offerings.

Specific Category Framework Comparison

EASA Standard Scenarios: STS-01 and STS-02

The EASA framework provides two pre-defined Standard Scenarios that simplify Specific category authorization. These scenarios define specific operational parameters, risk mitigations, and pilot competency requirements in advance, allowing operators to declare compliance rather than prepare full risk assessments.

STS-01 covers VLOS operations over controlled ground areas in populated environments using C5-class drones. This enables operations that would exceed Open category proximity limits — for example, roof inspections in residential areas where maintaining Open category distances from uninvolved people is impractical. Operators must complete STS-01 training through an approved organization and declare operations to their national authority.

STS-02 addresses BVLOS operations over sparsely populated areas using C6-class drones up to a maximum distance of 2km from the remote pilot. This is the first standardized BVLOS scenario in Europe, enabling applications like linear infrastructure inspection, agricultural monitoring, and environmental surveying. Additional ground observer requirements and communication protocols apply.

Both scenarios require specific drone class markings (C5 or C6) that meet defined technical standards including Remote ID, geo-awareness, and specific safety features. Drones without class markings cannot be used under STS declarations, which limits current applicability as the class-marked drone market matures.

For operations beyond STS parameters, operators must prepare a SORA (Specific Operations Risk Assessment) application. SORA has become the universal methodology for assessing and authorizing medium-to-high risk drone operations across EASA and increasingly beyond.

SORA: The Universal Risk Assessment

SORA methodology provides a structured framework for evaluating operational risk through ground risk classification, air risk classification, and the identification of required mitigations. Operations are assigned a SAIL level (Specific Assurance and Integrity Level) from I to VI based on their combined risk profile.

SAIL I and II operations represent the lowest Specific category risks and require basic organizational competencies. SAIL III and IV operations demand more comprehensive safety management systems, maintenance programs, and crew training. SAIL V and VI approach Certified category complexity and require the most rigorous organizational structures.

The ground risk assessment evaluates population density, infrastructure sensitivity, and the consequences of a drone impacting the ground. Mitigations like parachute systems, energy-limiting designs, or operational restrictions can reduce the ground risk class.

The air risk assessment considers the probability of encountering manned aircraft in the operational volume. Strategic mitigations (airspace restrictions, NOTAMs) and tactical mitigations (detect-and-avoid systems, coordination with ATC) reduce air risk class.

SORA 2.5, the latest version, introduces refined methodology for certain assessment elements and is required for new operational authorizations in the Netherlands from April 2026. Other EASA nations are progressively adopting SORA 2.5, so operators should prepare for the updated methodology.

UK: Operational Authorisations with SORA

The UK CAA's framework mirrors EASA's Specific category approach but operates independently post-Brexit. Operators apply for Operational Authorisations, with the level of assessment depending on operational complexity.

PDRA01 (Predefined Risk Assessment) provides a simplified path for certain VLOS operations, equivalent to STS in concept. The standard OA at £524/year covers many commercial VLOS operations. SORA-based applications for BVLOS and higher-risk operations start at £2,185.

The CAA has developed its own guidance on SORA implementation, including UK-specific considerations for airspace structure, population density assessment, and interaction with manned aviation. UK operators must use CAA templates and follow UK-specific risk assessment standards.

Processing times for SORA applications range from 4 to 12 weeks depending on complexity. The CAA provides feedback on incomplete applications, and operators can request pre-application meetings for complex operations to discuss approach before formal submission.

Non-EASA Equivalent Frameworks

Australia manages Specific-equivalent operations through expanded ReOC authorizations. Operators amend their ReOC to include new operation types, supported by risk assessments and operational procedures specific to the proposed activity. CASA evaluates each application against safety standards without a formalized SORA-equivalent methodology, though risk assessment principles are similar.

Canada uses the Special Flight Operations Certificate (SFOC) system. SFOC applications must include detailed operational plans, risk assessments, emergency procedures, and evidence of crew competency. Processing times range from 4 to 20 weeks. The upcoming RPOC system from November 2025 may introduce more structured assessment frameworks.

The US FAA uses Part 107 waivers for operations beyond standard limitations. Waiver applications are submitted through DroneZone with supporting safety documentation. The Operations Over People rule established standardized categories for one common waiver type, and the FAA continues developing frameworks to reduce reliance on individual waivers.

New Zealand's Part 102 framework allows operators to define their own operational procedures within an exposition approved by CAA NZ. This flexible approach enables Specific-equivalent operations without prescriptive scenarios, making it unique among the ten countries.

Japan enables higher-risk operations through the First Class UAS Pilot Certificate combined with operation-specific approvals from MLIT. The certification-based approach ensures pilot competency, while individual operation approvals address location-specific and operation-specific risks.

Building Your Specific Category Application

Regardless of country, strong Specific category applications share common elements. Start with a clear operational concept defining exactly what you intend to do, where, and under what conditions. Map every risk and identify specific, measurable mitigations for each. Document your organizational competencies including training records, maintenance procedures, and safety management systems.

Common weaknesses in applications include vague risk descriptions, unsubstantiated mitigation claims, incomplete emergency procedures, and failure to address all relevant risk categories. Authorities reject applications that demonstrate insufficient understanding of the risks involved.

Engaging with your national authority early in the process saves time. Many authorities offer pre-application guidance or informal discussions that help operators understand expectations before investing significant effort in formal documentation.

Frequently Asked Questions

What is the difference between Open and Specific category operations?

Open category covers low-risk operations with minimal authorization — typically VLOS, limited altitude, low weight, and away from people. Specific category applies when any of these limitations are exceeded, requiring either a Standard Scenario declaration or a full risk-based authorization. The key distinction is the level of risk assessment and organizational competency required.

Do I need SORA for all Specific category operations?

No. Within EASA, Standard Scenarios (STS-01, STS-02) provide pre-assessed pathways that require training and declaration but not a full SORA analysis. SORA is required for operations that exceed STS parameters. In non-EASA countries, equivalent simplified pathways exist alongside full risk assessment requirements for more complex operations.

How long does a Specific category authorization take to obtain?

Processing times vary from 4 weeks (simple UK PDRA applications, straightforward EASA STS declarations) to 20 weeks (complex Canadian SFOCs). Most full SORA applications take 6-12 weeks. Incomplete applications can significantly extend timelines. Planning 3-6 months ahead for complex operations is advisable.

Can I transfer a Specific category authorization between countries?

EASA authorizations have limited cross-border validity within EU/EEA states, but typically require coordination between national authorities. UK, US, Canadian, Australian, Japanese, and NZ authorizations are country-specific with no automatic recognition elsewhere. Multi-country operations generally require separate authorizations in each jurisdiction.

What happens if I operate in Specific category without authorization?

Penalties are severe across all countries. The UK can impose unlimited fines and up to 5 years imprisonment. Germany applies administrative fines up to €50,000. France can impose up to €75,000 plus 1 year imprisonment. The US applies civil penalties up to $27,500 per violation. All countries treat unauthorized Specific category operations as serious regulatory violations.
