IRELAND · Operational Risk Approval
What is an ARC and Why is it Important for Drone Operators?
For professional drone operators (UAS operators) in Ireland operating within the Specific category, an ARC is a crucial component of their risk management. ARC stands for Approved Risk Classification and involves an official assessment where the operational risk of a drone operation is evaluated and classified. This helps operators to fly safely, in compliance with European (EASA) and national (IAA) regulations, and forms a key component of the operational manual and the External Reference Plan (ERP).
What is an ARC Exactly?
An ARC is a formal risk classification issued by the competent authority in Ireland, the Irish Aviation Authority (IAA), based on a risk assessment for drone operations conducted within the Specific category. It defines the safety level that must be achieved and specifies the mitigations needed to manage identified risks effectively.
Typically, the ARC results from evaluation of a comprehensive safety dossier, often supported by a Specific Operations Risk Assessment (SORA) or a Pre-Defined Risk Assessment (PDRA). The ARC formally documents applicable operational restrictions and mandated safety measures for the approved drone operation.
- Definition of ARC (Approved Risk Classification)
- Issued by the competent national authority (IAA)
- Based on SORA or PDRA risk assessment
- Specifies operational limitations and safety mitigations
How Does a Drone Operator Apply for an ARC in Ireland?
In Ireland, an operator intending to conduct flights within the Specific category must submit an ARC application to the IAA. This request is part of the broader External Reference Plan (ERP) which encompasses the Concept of Operations (ConOps), the operational manual, safety assessments, and mitigations.
The application must present a detailed analysis justifying the risks associated with the operation and demonstrating how these risks are controlled to an acceptable level. Operators may base their submission on standard PDRAs for routine operations or provide a tailored SORA for more complex activities.
The IAA reviews the submitted dossier and can grant the ARC upon satisfactory demonstration of compliance with applicable safety criteria. To avoid processing delays, the dossier should be complete, well-structured, and clearly substantiated.
- Apply via IAA as part of the ERP submission
- Includes ConOps, operational manual, and risk assessments
- Use PDRAs or bespoke SORA for risk justification
- Well-prepared dossiers reduce evaluation time
Why is an ARC Important for Professional UAS Operators?
An ARC defines what drone operations are legally allowed under the Specific category and outlines the safety expectations operators must meet. Flying without a valid ARC in this category, when required, is not permitted under Irish law and EASA regulations.
Beyond legal compliance, the ARC serves as a risk management tool, enhancing operational safety and vigilance. It also communicates transparently to regulators, clients, and the public that the operator takes safety seriously and works within established standards.
Moreover, the ARC is a mandatory requirement per EASA framework for certain operations and scenarios, serving as a gateway for professional drone activities in Ireland and across the European Union.
- Mandatory under law for flights outside the Open category
- Controls and mitigates operational risks effectively
- Ensures adherence to European and Irish drone regulations
- Builds trust with regulators, customers, and the public
Common Mistakes and Tips When Applying for an ARC
Operators often encounter setbacks due to incomplete applications or insufficiently detailed risk assessments. These deficiencies commonly cause processing delays or application refusals by the IAA.
To improve application success:
• Provide a comprehensive and accurate operational manual that clearly documents safety procedures.
• Utilize recognised PDRAs for standard scenarios wherever applicable to streamline the process.
• Clearly describe and justify safety mitigations in concrete, achievable terms.
ARC in the Context of EASA Risk Assessment Tools
The ARC is rooted in the European Union Aviation Safety Agency's risk assessment framework, which explicitly identifies and controls drone operation risks through methodologies such as the Specific Operations Risk Assessment (SORA). SORA provides a structured approach to identify, evaluate, and mitigate risks tailored to specific operations.
Pre-Defined Risk Assessments (PDRAs) simplify this process by offering pre-approved risk assessments for typical, repetitive scenarios, enabling quicker ARC issuance for standard operations.
Once granted, the ARC integrates directly into the operator's operational manual and the External Reference Plan (ERP), essential documents for regulatory audits and oversight.
- ARC originates from SORA and PDRA frameworks
- SORA requires bespoke risk analysis for unique flights
- PDRAs speed up the ARC process for common operations
- ARC forms part of operational manual and ERP documentation
Frequently asked questions
What is the difference between an ARC and a PDRA?
A PDRA is a pre-defined risk assessment for standard drone operations, whereas an ARC is the risk classification formally approved by the IAA based on analysis that may involve a PDRA or a bespoke SORA study.
Is an ARC mandatory for all drone operators?
No, an ARC is specifically mandatory for operators conducting flights within the Specific category that require risk assessments and fall outside the Open category operations.
How long is an ARC valid?
The validity period of an ARC depends on conditions set by the IAA and the operational risk profile stability; typically, validity terms are defined at approval and can be reviewed or renewed as required.
Can I fly a drone in Ireland without an ARC?
If you operate solely within the Open category according to its general rules, an ARC is not required. For Specific category operations requiring risk assessment, holding a valid ARC is mandatory.
What is the relationship between the ARC and the operational manual?
The ARC specifies required safety measures and operational limitations, which must be reflected and implemented within the UAS operator's operational manual.
