STS-01 Explained: What It Is and How to Apply It as a Drone Operator
As a drone operator in Ireland, understanding STS-01 is essential for conducting low-risk operations. This article explains what STS-01 is, its requirements, and how to implement it in your operational procedures.
What Is STS-01?
STS-01, or Standard Scenario 1, is a streamlined framework developed by the European Union Aviation Safety Agency (EASA) to facilitate specific low-risk drone operations within the Specific category. It is designed for drones operating within the visual line of sight (VLOS) of the remote pilot over a controlled ground area in a populated environment, with an operational ceiling of 120 metres above ground level.
Drones must be CE marked with a class C5 label to meet the equipment standards required for STS-01 operations. This standard scenario aims to reduce the administrative and regulatory burden by providing a pre-defined operational risk model that operators can follow to obtain swift authorization from the competent authority.
- Standardised low-risk drone operation framework
- Developed by EASA for Specific category operations
- Requires CE class C5 drone equipment
- Maximum altitude of 120 metres over controlled ground area in populated environments
Requirements for STS-01
To operate under STS-01 in Ireland, drone operators must meet strict criteria ensuring safety and compliance. Key requirements include:
1. Equipment: The drone must have safety systems such as automatic return-to-home and advanced obstacle detection and avoidance technologies, consistent with EASA’s class C5 specifications.
2. Operational Procedures: Operators need documented operational procedures aligned with STS-01 standards, describing management of flight operations, emergency response, and safety measures.
3. Remote Pilot Training and Qualification: Remote pilots must hold a valid theoretical knowledge certificate and a practical skills accreditation, both obtained through IAA-recognised training organisations or examination centres.
4. Insurance: Adequate liability insurance must cover the operational risks for all STS-01 flights.
- Mandatory drone equipment safety features
- Documented and compliant operational procedures
- Certified remote pilots with theoretical and practical credentials
- Valid third-party liability insurance
- Notification to IAA via UAS Operations Declaration
Applying STS-01 in Ireland
The Irish Aviation Authority (IAA) serves as the aviation safety regulator responsible for enforcing drone operation rules in Ireland. Operators wishing to conduct STS-01 operations must submit a UAS Operations Declaration through the IAA's dedicated online portal.
This declaration confirms compliance with all technical, procedural, and personnel requirements set forth in Appendix 1 of Implementing Regulation (EU) 2019/947. It covers drone specifications, operational zones, and the pilot’s qualifications.
Operators must register with the IAA and obtain an operator registration number prior to submission. While the regulatory framework is harmonised under EASA, specific administrative steps or forms can be verified directly on the IAA website to ensure current compliance.
- IAA is the competent authority for drone operations
- Submit UAS Operations Declaration via IAA online portal
- IAA registration and operator number mandatory
- Ensure full compliance with EU Implementing Regulation 2019/947 Appendix 1
Frequently asked questions
What is the difference between STS-01 and other SORA scenarios?
STS-01 applies specifically to low-risk operations where the drone operates within visual line of sight over a controlled area in a populated environment, using standardised procedures and certified equipment. Other SORA scenarios address higher risk operations requiring tailored risk assessments (SORA), detailed Concept of Operations (ConOps), and may demand additional safety mitigations and approvals.
Do I have to use STS-01 for every drone operation?
No. STS-01 is applicable only for specific low-risk operations defined by EASA. For operations beyond the STS-01 scope, such as Beyond Visual Line of Sight (BVLOS) or operations over uninvolved people, operators must perform a full Specific Category risk assessment often following the SORA methodology and seek individual operational authorisation from the IAA.
Where can I find the official STS-01 requirements for Ireland?
The fundamental requirements come from EASA’s Implementing Regulation (EU) 2019/947, Appendix 1, supplemented by national procedures available from the Irish Aviation Authority. Operators should verify the latest process and document templates on the IAA’s official website.
Is pilot training mandatory for STS-01 operations?
Yes. Remote pilots must complete theoretical knowledge training and practical skills accreditation as prescribed by EASA standards and the IAA. These certifications ensure pilots are competent to safely conduct operations within the scope of STS-01.
