Development and Regulation of Civil Drones: Lessons from Switzerland and Recommendations for the UK
By Richard Ryan, Drone Lawyer

Introduction
Switzerland has emerged as a leading hub for drone innovation, in large part due to forward-looking policies and the seamless integration of unmanned aircraft into its broader aviation ecosystem. Although the UK has already adopted a risk-based regulatory framework for drones, lessons from the Swiss and European Union Aviation Safety Agency (EASA) experience could further advance the UK’s domestic industry.
This article compares Swiss and UK drone regulations, with a view to determining whether a more comprehensive legislative revision—drawing on Swiss and EASA best practices—could enhance safety, innovation, and public acceptance in the UK.

1. Background and Goals

1.1. Switzerland’s Drone Ecosystem
Switzerland’s success in fostering a dynamic civil drone industry rests on the following pillars:
1. Risk-Based Regulatory Model
Switzerland follows the three-category approach (Open, Specific, and Certified) as set out in the core EU regulations (Regulation (EU) 2019/947 and Regulation (EU) 2019/945), which it adopts under its bilateral air transport agreements with the EU.
2. Close Collaboration
Federal agencies (e.g., the Federal Office of Civil Aviation, FOCA), industry, and research institutions routinely coordinate to address regulatory and technological developments.
3. Strong International Ties
As a signatory to multiple bilateral and multilateral agreements (including the Agreement between the EU and the Swiss Confederation on Air Transport), Switzerland ensures legal certainty and alignment with global safety standards.

1.2. The UK Context
The UK also employs a risk-based framework, primarily structured by:
• The Air Navigation Order 2016 (ANO), as amended
• Civil Aviation Authority (CAA) publications, including CAP 722, which provides operational guidance for unmanned aircraft.
Although the UK’s regulations are already comprehensive, there is scope to streamline approval processes, bolster public confidence, and prepare for emerging drone technologies. Swiss and broader EASA approaches—particularly in the realm of U-Space services—offer potentially valuable lessons.

2. Swiss Legal Framework

2.1. Adoption of EU Drone Regulations
Under Swiss law, drones are governed by EU regulations (Regulations (EU) 2019/947 and 2019/945) through Switzerland’s bilateral air transport agreements with the EU. In practice, FOCA enacts these rules at the national level, sometimes incorporating local adaptations based on Swiss administrative structures.
2.1.1. Drone Categories
1. Open (low risk)
o Operations with minimal restrictions if the drone meets specific technical requirements (e.g., weight, speed, altitude limits) and usage conditions.
2. Specific (medium to high risk)
o Requires more rigorous operational authorisations and safety risk assessments.
3. Certified (highest risk)
o Applies to complex or large-scale operations, including cargo and passenger transport (e.g., eVTOL aircraft), though these frameworks are still evolving.
2.1.2. Integration with Traditional Aviation
• Coordination Through Skyguide: Switzerland’s air navigation service provider, Skyguide, is tasked with managing both manned and unmanned traffic. This seamless integration aims to promote safety and efficiency in shared airspace.
• National Emphasis on Collaboration: Swiss authorities maintain regular consultation with industry, research, and cantonal authorities to adapt regulations swiftly.
Relevance for the UK
• Risk Categorisation: The UK already uses a three-tier classification (Open, Specific, Certified), mirroring the Swiss/EASA approach.
• Approval Process: Automating and digitising authorisations—an area where Switzerland and Skyguide have been especially proactive—may help reduce administrative burdens for UK operators.

3. U-Space Infrastructure and Multiple Service Providers

3.1. What Is U-Space?
U-Space is a digital ecosystem designed to manage drone traffic autonomously or semi-autonomously. It includes network identification, flight authorisation services, and real-time data exchange among airspace users.

3.2. Switzerland’s U-Space Approach
• Multiple U-Space Service Providers (USSPs):
Switzerland aims to license several private or public providers within the same geographical area, fostering competition and innovation in drone traffic management.
• Key Features:
1. Network Identification: Ensures authorities (and possibly the public) can identify drones operating in U-Space airspace.
2. Automated Flight Authorisation: Minimises manual checks by aviation authorities.
3. Real-Time Data Exchange: Coordinates positions and flight plans among manned aircraft, unmanned aircraft, and air traffic control.

3.3. Implementation Timelines
• By 2025: Switzerland has signalled its intent to launch initial U-Space operations in regions including Zurich. [1]
• By 2030: Widespread U-Space maturity is anticipated across Europe, though this is an industry projection rather than a formal deadline.
Relevance for the UK
• Competition and Choice: Licensing multiple USSPs could provide UK operators with varying price points and service levels, driving innovation.
• Incremental Roll-Out: Concentrating U-Space in high-traffic urban areas first (London, Manchester, etc.) may mirror Zurich’s approach.
• Legal and Technological Foundation: Adapting the EU’s Implementing Regulation (EU) 2021/664 for U-Space to the UK’s post-Brexit landscape could maintain interoperability with European markets.

4. Noise Protection Measures

4.1. Swiss Perspective
Swiss authorities acknowledge that drone noise—while generally quieter than conventional aircraft—can be disruptive in residential or rural areas. Ongoing efforts include:
• Collaborating with EASA and ICAO working groups to develop drone-specific noise measurement standards.
• Encouraging technological innovations (e.g., quieter propellers, electric propulsion).
• Using geo-awareness tools to route flights around noise-sensitive areas.

4.2. Relevance for the UK
• Comprehensive Noise Mapping: Incorporating drone flight paths into local noise maps could help councils and the CAA manage public disturbances.
• Research and Design: Funding drone acoustics research could ensure any future noise regulations are evidence-based.
• Aligning Standards: Remaining aligned with emerging international noise standards could ease cross-border drone operations and manufacturing.

5. Privacy and Public Acceptance

5.1. Swiss Measures
• Mandatory Registration: Most drone operators must register and display their registration number, subject to weight and operational criteria.
• Remote Identification: Allows law enforcement and authorities to identify drones in real time, enhancing accountability.
• Geofencing and Flight Restriction Zones: Critical infrastructure or sensitive sites often have automated restrictions to prevent overflights.

5.2. Relevance for the UK
• Building Public Trust: The UK’s existing registration regime (for drones ?250g) could be coupled with more transparent robust remote ID requirements.
• Enforcement and Complaint Handling: Close coordination with local police and councils may expedite response times to drone-related incidents.
• Regulatory Consistency: Ensuring geofencing data is accurate and accessible will be crucial as drone usage scales up.

6. Spatial Planning and Infrastructure

6.1. Current Swiss Policy
• Different Treatment vs. Conventional Aviation: Small drone operations typically require minimal infrastructure and thus face limited planning procedures.
• “Intensive Use” Threshold: FOCA guidelines suggest that where a single site exceeds a certain number of flights (sometimes cited as over 1200 flights per year), formal land-use planning and environmental assessment may be triggered. However, application may vary depending on local (cantonal) regulations.

6.2. Future Vertiports
Swiss authorities anticipate the need for dedicated vertiports or droneports if large passenger/cargo eVTOLs become more commonplace. These facilities would require integration into national transport and aviation infrastructure plans.

6.3. Relevance for the UK
• Planning Approvals: The UK might consider more streamlined pathways for drone infrastructure, acknowledging that small drone operations have lower impact than full-scale airport developments.
• Emerging eVTOLs: A forward-looking approach—coordinated among the Department for Transport, local councils, and industry—could accommodate vertiport networks in urban hubs.
• Local Variations: Like Switzerland, the UK may allow local authorities discretion in how to apply thresholds for “intensive use,” but national guidance would help maintain consistency.

7. Environmental Sustainability

7.1. Potential Emissions Reductions
• Replacing Conventional Aircraft: Small drones can potentially replace helicopters for tasks like aerial surveys, agricultural spraying, or urgent deliveries, leading to immediate fuel and emissions savings.
• Lifecycle Analyses: Comprehensive studies are still limited, so definitive data on net environmental impact remains inconclusive.

7.2. Relevance for the UK
• Targeted Incentives: Encouraging drone use in sectors where carbon-intensive operations are widespread (e.g., logistics, agriculture, medical supply chains) could yield environmental benefits.
• Data Collection: Collaborating with academia and industry to produce rigorous lifecycle analyses would strengthen policy decisions.

8. Should the UK Revise Its Complex Legislation?

Given Switzerland’s experience and the growing demands of the UK drone sector, there is a robust case for a holistic review of UK drone regulations. Although the current framework—anchored in the Air Navigation Order 2016 and supplemented by CAP 722—is risk-based, integrating the best practices from Swiss and EASA models could amplify innovation and public trust.

8.1. Harmonising with EASA
• Voluntary Alignment: While the UK is no longer bound by EASA regulations post-Brexit, aligning technical and operational standards can facilitate cross-border operations and exports.
• Regulatory Autonomy: The UK can selectively adopt or adapt EASA rules that best serve its domestic market.

8.2. Streamlining Authorisations and Planning
• Digital Transformation: Emulating Switzerland’s push for automated approvals could reduce administrative burdens for operators in the UK.
• Consistent Local Guidance: As drones become integral to city services, local authorities should follow uniform guidelines on planning consent.

8.3. Fostering Public Trust
• Noise and Privacy Protections: Enhanced noise mapping, remote ID, and geofencing can address some of the most common community concerns.
• Robust Enforcement: Clear lines of responsibility between the CAA, local councils, and law enforcement agencies will be key.

Conclusion

Switzerland’s structured yet adaptive approach—emphasising competitive U-Space services, data-driven noise mitigation, robust privacy measures, and collaborative policymaking—offers valuable lessons for the UK. Despite a well-established risk-based framework, the UK could benefit from a more comprehensive review that incorporates Swiss successes and maintains compatibility with EASA standards where beneficial.
By welcoming multiple U-Space Service Providers, digitising authorisations, and preparing for future vertiport infrastructure, the UK can remain at the forefront of drone technology. A more cohesive and modernised legal framework, coupled with effective enforcement and public engagement, will lay the foundation for a thriving, responsible, and future-ready UK drone sector.
