Drone Law | UK SORA | CAA Regulation | AI Governance

Summary: CAA Decision No. 60 marks a significant development in the regulation of Specific category drone operations in the UK. Coming into force on 1 October 2026, it updates the UK SORA framework and introduces clearer expectations around compliance evidence, ground-risk mitigation, containment, kinetic energy analysis and evidence retention. For operators, the message is clear: compliance is no longer just a narrative safety case. It must be evidenced, retained and auditable.

1. Why Decision No. 60 Matters

The UK’s lower airspace is becoming increasingly complex. Beyond Visual Line of Sight operations, drone delivery, infrastructure inspection, emergency services use, autonomous routing and higher-risk commercial UAS activity all require a more mature regulatory framework.

CAA Decision No. 60 updates the Acceptable Means of Compliance and Guidance Material for UK Regulation (EU) 2019/947. In practical terms, it strengthens the UK Specific Operation Risk Assessment, or UK SORA, for operators seeking authorisation in the Specific category.

The legal significance is that UK SORA is becoming a structured assurance methodology. Operators must not merely state that an operation is safe. They must demonstrate that the aircraft, procedures, people, operational volume, ground environment, airspace risks, mitigations and emergency arrangements meet the required level of safety.

2. UK SORA Is Not a Box-Ticking Exercise

UK SORA exists to support the operational risk assessment required for Specific category operations. It considers both ground risk and air risk, then applies mitigations and operational safety objectives according to the Specific Assurance and Integrity Level, or SAIL.

The updated framework is particularly important because it clarifies how operators must gather, present and retain compliance evidence. This is a move away from generalised operational assertions and towards aviation-grade documentation.

3. The Three Compliance Pathways

Decision No. 60 identifies three broad routes for demonstrating compliance.

Operators must also retain compliance evidence for the duration of the operational authorisation and for three years after operations under that authorisation cease. That evidence may become critical in a CAA audit, incident investigation, insurance dispute or civil claim.

4. Ground Risk: What Happens If the Drone Falls?

Ground risk is central to UK SORA. The law is concerned not only with whether the drone can fly, but with what happens if it fails. Decision No. 60 provides more detailed guidance on how operators may reduce ground risk.

5. Kinetic Energy and Penetration Risk

Decision No. 60 gives particular importance to kinetic energy. This matters because it converts safety claims into measurable injury-risk analysis.

Operators should not rely on generic manufacturer statements. They need platform-specific evidence: mass, velocity, terminal impact behaviour, parachute performance, battery fire risk and representative structural analysis.

6. Containment and Fly-Away Risk

Containment is a central pillar of the updated UK SORA framework. It asks whether the unmanned aircraft can be kept within its operational volume and ground risk buffer, even after failure or loss of control.

For lower-risk operations, containment may be assessed qualitatively through design appraisal and procedural evidence. For higher-risk operations, the CAA may expect quantitative probability targets, such as demonstrating that the probability of exiting the relevant volume or buffer is below specified thresholds per flight hour.

Containment evidence may include geo-caging, tethering, independent flight termination systems, lost-link logic, command-and-control resilience, navigation integrity, power-system independence and emergency procedures.

7. EU AI Act and UK AI Standards

Decision No. 60 is not an AI regulation. However, many modern drone operations increasingly rely on AI-enabled functions, including detect-and-avoid, automated route planning, computer vision, landing assistance, ground-person detection, predictive maintenance and autonomous contingency management.

The EU AI Act is relevant as a benchmark for risk management, technical documentation, record-keeping, transparency, human oversight, robustness and cybersecurity. The UK does not currently have a single equivalent UK AI Act. Instead, it follows a sector-led, principles-based model based on safety, security and robustness; transparency and explainability; fairness; accountability and governance; and contestability and redress.

8. Data Protection and Surveillance Risk

Many Specific category operations involve cameras, thermal imaging, mapping payloads or AI-enabled object recognition. UK SORA primarily addresses safety, but operators must also consider privacy, data protection and surveillance risk.

If cameras or AI systems detect uninvolved persons, personal data may be captured, stored or analysed. Operators may need a data protection impact assessment, retention limits, access controls, privacy notices and clear rules on secondary use.

9. What Operators Should Do Before 1 October 2026

Operators should review their safety cases and evidence packs now. In particular, they should check:

• Aircraft mass, speed, kinetic energy and terminal velocity;
• Ground-risk assumptions and population-density evidence;
• Sheltering, operational restriction and observation claims;
• Parachute, flight termination and impact mitigation evidence;
• Containment evidence, including geo-caging and lost-link logic;
• AI-enabled functions, including detect-and-avoid and automated decision-support tools;
• Evidence retention systems;
• Supplier contracts for access to technical data.

10. Bottom Line

CAA Decision No. 60 marks a shift from descriptive drone safety cases to structured assurance. Operators must now be able to prove their safety claims through coherent, retained and auditable evidence.

The most important development is the convergence between aviation safety and AI governance. UK SORA asks whether the drone operation is safe. The EU AI Act and UK AI principles ask whether automated systems are risk-managed, documented, robust, explainable, secure and subject to human oversight. For modern drone operations, those are increasingly the same question.

Compliance is not what the operator says it does. Compliance is what the operator can prove.

The post Navigating UK SORA: A Drone Lawyer’s Guide to CAA Decision No. 60 appeared first on Blakistons.

From 1 January 2026, the UK drone regulatory framework enters a new phase. While the underlying legal structure remains based on the Air Navigation Order 2016 and UK UAS Regulations, several operational changes are being introduced. Understanding the distinction between legislation, Civil Aviation Authority guidance, and industry practice is now essential.

This article provides a practical legal overview of the key changes affecting recreational and commercial drone operators flying within the Open Category in the United Kingdom.

Law and Guidance Are Not the Same Thing

One of the most common misunderstandings among drone operators is the assumption that everything in the Drone Code or CAA guidance is itself law.

The legal framework consists primarily of legislation, including the Air Navigation Order 2016 and UK UAS Regulations. These are the provisions under which enforcement action and prosecutions may occur.

The CAA also publishes guidance, including CAP 722, Acceptable Means of Compliance and the Drone Code. These materials are highly important, but they are generally guidance rather than legislation. Compliance with them will usually be persuasive evidence of safe and responsible operation.

A useful way to think about compliance is:

• Green: operating within CAA guidance and published best practice.
• Amber: operating within the law but outside guidance.
• Red: operating outside the legal framework.

Flying outside guidance may sometimes remain lawful, but operators must be ready to justify their decisions if challenged by the police, the CAA or a court.

Registration Requirements

Most drones with a camera and weighing more than 100 grams require registration under the Drone and Model Aircraft Registration and Education Scheme.

Operators will generally need both an Operator ID and a Flyer ID.

The Operator ID identifies the person responsible for the aircraft and must be displayed on the drone. The Flyer ID confirms that the pilot has passed the required competency test and remains valid for five years.

Importantly, it is the operator who is registered rather than the drone itself.

Universal Rules for All Drone Flights

Maximum Altitude

The maximum operating height remains 120 metres, or 400 feet, above the closest point of the earth’s surface. This matters particularly when flying near cliffs, hills, mountains or other changing terrain.

Visual Line of Sight

Visual Line of Sight remains a central requirement of UK drone regulation.

The pilot must be able to see the aircraft sufficiently to avoid collisions in the air and manage risks on the ground. Seeing only a small dot or relying solely on navigation lights is unlikely to be defensible if an incident occurs.

First Person View Flying

Where FPV goggles are used, a competent observer or spotter is generally required. The spotter should remain beside the pilot and maintain awareness of air and ground hazards while the pilot is focused on the video feed.

Airspace Restrictions

Many drone prosecutions arise from breaches of airspace restrictions rather than from technical flying errors.

Airspace should be checked before every flight using a reliable and current source of aeronautical information. The information should be refreshed immediately before launch.

Key restriction types include:

• Flight Restriction Zones: permanent restricted areas around airports, prisons and protected sites.
• Temporary Restrictions: restrictions created for events, security operations and public safety purposes.
• NOTAMs: aviation notices which may affect drone operations.

Operators should use modern airspace mapping tools and should not assume that yesterday’s airspace position remains correct today.

A1, A2 and A3 Operational Categories

A1: Flying Over People

The A1 category provides the greatest flexibility. Certain drones under 250 grams may be flown over uninvolved persons, although flight over crowds remains prohibited.

This category generally includes legacy drones under 250g, UK0 and UK1 aircraft, C0 aircraft and C1 aircraft subject to transitional provisions.

A2: Flying Close to People

A2 operations allow flight near uninvolved persons but generally prohibit flight directly over them. Operators normally require an A2 Certificate of Competency.

Certain UK2 and C2 aircraft may operate with reduced separation distances where the applicable requirements are met.

A3: Flying Far from People

A3 operations are intended for open areas away from uninvolved persons and built-up environments.

Operators must generally maintain 50 metres from uninvolved persons and 150 metres from residential, commercial, industrial and recreational areas.

Article 16 Authorisations

Members of recognised model aircraft and drone associations may benefit from Article 16 Authorisations. These permissions can provide greater operational flexibility, including reduced separation distances and access to some locations that would otherwise be more restricted under the Open Category framework.

Ground Hazards and Article 241

Even where all technical drone requirements are satisfied, operators remain subject to wider safety duties.

Article 241 of the Air Navigation Order provides that a person must not recklessly or negligently cause or permit an aircraft to endanger any person or property.

Ground hazards may include members of the public, vehicles, buildings, infrastructure, wildlife and protected environmental sites.

Particular care should be taken when operating near Sites of Special Scientific Interest and other environmentally protected areas.

Remote ID Arrives in 2026

One of the most significant developments is the introduction of Remote ID.

Remote ID creates an electronic identification system allowing drone operations to be identified through information transmitted by the aircraft.

Implementation is being phased in. New UK1, UK2 and UK3 drones released from 2026 will require Remote ID functionality. Existing aircraft will transition over a longer implementation period extending towards 2028.

Operators should monitor CAA updates closely as implementation progresses.

Night Flying Requirements

Night flying remains permissible within the Open Category.

From 2026, operators will generally require a green flashing light attached to the aircraft.

The purpose of the light is to assist people on the ground in recognising the aircraft as a drone. It should not be treated as a substitute for maintaining Visual Line of Sight.

Insurance and Operational Responsibility

Recreational operators are generally not legally required to carry insurance, although doing so is strongly recommended.

Commercial operators typically require specialist aviation insurance compliant with applicable regulatory requirements.

Pilots should also ensure they are fit to fly, avoid operating under the influence of alcohol or drugs, and remain alert to low-flying manned aircraft at all times.

Conclusion

The 2026 changes represent an evolution rather than a revolution in UK drone regulation.

The key principles remain unchanged: understand the law, check airspace before every flight, maintain Visual Line of Sight, operate safely and proportionately, and keep abreast of developments concerning Remote ID and future airspace integration.

For most operators, compliance remains straightforward. Those who understand the distinction between legislation and guidance, conduct appropriate pre-flight planning and adopt a risk-based approach should continue to fly safely and lawfully throughout 2026 and beyond.

Soaring Ahead or Stuck in the Past? What the CAP 3040 Second Edition Means for Your Drone Operations

By Richard Ryan, Drone Lawyer

As a UK drone lawyer, I’ve seen firsthand how tricky it can be to navigate the ever-changing skies of unmanned aviation regulation. The Civil Aviation Authority’s (CAA) “Unmanned Aircraft Operations in an Atypical Air Environment (AAE): Policy Concept” (CAP 3040) is no exception. After the initial excitement of the First Edition, many in the drone community were eagerly awaiting the Second Edition, hoping for clarifications, improvements, and a more future-focused framework.

What’s New?
At a glance, the changes between the First and Second Editions might seem minimal—just a tweak to the reference for ADS-B (Automatic Dependent Surveillance-Broadcast) equipment, rolling back from RTCA DO-282C to the older DO-282B standard. But that’s not a small footnote. If you’ve been prepping your drone gear to meet DO-282C standards, you may now be left wondering why the rug’s been pulled from under you.

The Tech Twist:
DO-282B is an earlier standard for ADS-B performance, while DO-282C was supposed to reflect newer technology and real-world lessons learned. Reverting to an older standard could mean extra work or unexpected costs if you’ve already made purchases or adapted your systems for DO-282C. It also raises questions about whether the policy is truly forward-looking, or inadvertently stifling progress at a critical time in UK drone innovation.

Still Flying Through Foggy Regulations:
The Second Edition still leaves operators wrestling with a few nagging uncertainties:
1. Defining ‘Atypical Air Environment’: The document still lacks a crystal-clear definition of AAE. Without a firm legal baseline, you might struggle to know if your flight qualifies—adding confusion to your operations and potentially slowing down approvals.
2. Single Site Limitations: The CAA’s recommended approach of applying for just one site per Operational Authorisation (OA) remains. This can create unnecessary hurdles for those looking to scale up and serve multiple clients or routes.
3. Extra Admin, Less Innovation: Requirements like routine NOTAM submissions or intricate Electronic Conspicuity (EC) licensing haven’t been simplified. For many operators, these processes feel more bureaucratic than beneficial, potentially discouraging new entrants and curbing the industry’s growth.

How to Navigate This Airspace Turbulence:
• Stay Agile: Keep tabs on CAA communications and industry forums. If the CAA shifts requirements again, you’ll want to pivot quickly.
• Ask for Clarity: Don’t hesitate to reach out to uavenquiries@caa.co.uk for guidance, especially if you’ve already invested in tech aligned with DO-282C.
• Industry Collaboration: Connect with fellow operators, manufacturers, and drone associations. Shared experiences help identify practical solutions and give your concerns more weight when approaching regulators.
• Professional Advice: A drone-focused legal expert can help you interpret the Second Edition’s nuances, reduce compliance guesswork, and ensure you’re not sinking costs into the wrong standards.

Charting a Better Flight Path: While the Second Edition’s updates may feel like a step back, there’s still hope. The CAA emphasizes that CAP 3040 is an evolving concept. By voicing concerns, sharing data, and staying engaged, the drone community can help steer policy revisions that balance safety, innovation, and economic growth.

The Bottom Line:
The CAP 3040 Second Edition is a reminder that regulatory frameworks are works in progress. This can be frustrating, yes—but it’s also an opportunity. Operators willing to adapt, learn, and advocate for sensible changes can help shape the UK’s drone landscape into one that truly welcomes innovation. Keep your engines running, your channels of communication open, and your ambitions high. Together, we can ensure that tomorrow’s regulations are as cutting-edge and future friendly as the drone technology they’re meant to guide.

Transforming UK Airspace: A New Era for Drones and Aviation with NATS OpenAir

By Richard Ryan, Drone Lawyer

The skies over the UK are on the verge of a transformative shift, thanks to the ambitious NATS OpenAir initiative. Designed to integrate drones and advanced air mobility (eVTOLs) into shared airspace alongside traditional aircraft, the proposal promises innovation, efficiency, and safety. But as with any grand vision, the devil is in the detail.
Here’s an in-depth look at what the OpenAir initiative is getting right, where there are gaps, and how it can evolve to meet the needs of all airspace users.
________________________________________
1. Prioritising Data Privacy and Ownership

One of the most valuable resources in aviation is data. For drone operators, who depend on real-time information about flight paths, weather, and airspace restrictions, access to reliable data is critical. However, the OpenAir proposal is light on specifics about who owns the data and how privacy will be protected.
Without clear protections, drone operators might worry about their data being exploited—whether commercially or in ways that jeopardise their competitive edge.

The Fix:
OpenAir must adopt a clear data privacy framework. Operators should retain ownership of their data, with mandatory anonymisation for any information shared beyond essential safety and operational use. Only the bare minimum of data required for regulatory compliance should be shared, and stringent safeguards must prevent its misuse.
________________________________________
2. Keeping the Playing Field Fair

OpenAir is envisioned as a centralised hub for managing UK airspace, which sounds great—until you consider the potential impact on smaller players. Consolidating services under one entity like OpenAir might inadvertently stifle competition among Uncrewed Traffic Management Service Providers (UTMSPs).

The Fix:
To level the playing field, OpenAir should adopt open standards that allow seamless third-party integration. Smaller UTMSPs must be supported, not sidelined. Clear rules around equitable access to data and services will ensure innovation thrives without creating monopolies.
________________________________________
3. Setting Realistic Timelines

Integrating drones and eVTOLs into shared airspace isn’t a simple task. OpenAir’s proposed rollout timeline—beginning pilots in 2025 and achieving full deployment by 2028—might be overly ambitious, especially given the complexity of regulatory approvals and the need for robust infrastructure.

The Fix:
A phased approach with realistic benchmarks is the way forward. OpenAir should focus on pilot projects in key areas where demand is highest (e.g., urban delivery drones or emergency medical services). This would provide valuable data to refine the system while reducing the risk of rushed implementation.
________________________________________
4. Managing Costs for Drone Operators

OpenAir’s “user pays” principle makes sense in theory—those who use the airspace services should cover the costs. But smaller operators, such as local delivery drone companies, could be disproportionately affected by high fees, potentially pricing them out of the market.

The Fix:
Introduce tiered pricing. Small operators should pay less, at least during the initial phases. Alternatively, subsidies or credits could be offered to early adopters, ensuring fair access while fostering adoption across the board.
________________________________________
5. Addressing Legal Grey Areas

OpenAir aligns with the UK’s Airspace Modernisation Strategy, but its relationship with existing regulations like CAP 722 (which governs drone operations) needs to be crystal clear. Ambiguities in compliance requirements could delay approvals or lead to legal disputes.
Similarly, liability concerns loom large. If there’s a system outage or data error, who’s responsible for the fallout? Drone operators? OpenAir? The CAA? NATS? DfT?

The Fix:
OpenAir must explicitly state how its services integrate with CAP 722, especially for critical areas like Beyond Visual Line of Sight (BVLOS) operations. As for liability, service agreements must clearly define responsibilities, ensuring all parties—operators, OpenAir, and regulators—understand their obligations.
________________________________________
6. Building Trust Through Transparency

For OpenAir to succeed, trust is key. Stakeholders—including drone operators, regulators, and public service agencies—must feel confident in the system’s fairness and security.

The Fix:
Establish an independent advisory board with representatives from all key groups, including Blakiston’s Chambers! This board would oversee the rollout of OpenAir, ensuring transparency and accountability. Regular public updates and feedback sessions would further build trust and address concerns early.
________________________________________
7. Looking to the Future

The potential of OpenAir is undeniable. By creating a unified platform for managing UK airspace, it could unlock opportunities ranging from efficient logistics to life-saving medical deliveries. But to truly succeed, OpenAir must:
1. Prioritise data privacy and ownership.
2. Ensure fair competition for all service providers.
3. Adopt a phased, realistic rollout plan.
4. Keep costs manageable for smaller operators.
5. Align with existing regulations like CAP 722.
6. Address liability concerns upfront.
7. Foster trust through transparency and stakeholder engagement.

The skies above us are changing, and with thoughtful planning, OpenAir could make the UK a global leader in integrated airspace management. But to get there, it must balance ambition with practicality, ensuring the system works for everyone—from global eVTOL operators to local delivery drones.

This case highlights the complexity of balancing Section 76 of the Civil Aviation Act 1982 with trespass laws. Section 76 offers protection when drones fly at a “reasonable height,” but this case found that using drones for unauthorised photography over a site nullified such protection. Additionally, the court ruled that the very act of flying drones for unlawful purposes could constitute trespass, even without exact evidence on flight height.

For drone operators, this ruling underlines the need for compliance with air navigation laws, obtaining property owner consent, and carefully considering the purpose and operation of drone flights. As the sector evolves, it’s crucial to stay updated with legal developments to avoid potential liability.

Key Takeaways:

• Section 76 protections may not apply if drones are used for improper purposes.
• The court is increasingly willing to view drone use in trespass contexts.

Drone operators should obtain permission for flights over private property and comply with regulations to mitigate legal risks.
A list of relevant questions for the Civil Aviation Authority (CAA) in light of the Anglo International Upholland Ltd v Wainwright [2023] case:

1. How does the CAA interpret “reasonable height” under Section 76 of the Civil Aviation Act 1982 for drone flights over private property?
2. Does the CAA plan to update its guidance on drone operations to address trespass concerns post- Wainwright*?
3. What steps should drone operators take to ensure compliance with both air navigation laws and property trespass rules
4. Will there be new regulations requiring landowner consent for drones flying over private property?
5. How does the CAA plan to enforce penalties for drones used unlawfully over private property?
6. Could the CAA clarify its position on privacy violations and trespass when drones capture images without consent?
7. What considerations are in place for determining unlawful drone use, even if the flight does not breach flight height limits?
8. Is there a possibility for the CAA to introduce more stringent guidelines for recreational versus commercial drone flights regarding private land?
9. How should drone operators document compliance to avoid liability under both CAA regulations and civil trespass claims?
10. Does the CAA foresee future collaborations with property law bodies to provide comprehensive guidance on airspace use above private land?

1.There is reference to the commanders flying experience in hours, which included the last 90 days and the last 28 days. Are your records up-to-date?

2. The operators Operating Safety Case (OSC) contained several statements that were shown to be untrue. What does your OSC state?

3. In this case the CAA did not meet the operator or inspect the UA before the accident flight. Why not invite the CAA to inspect your platform so that you have it on record?

4. The CAA were not present at the test flight. Why not invite the CAA to attend the test flight?

5. The UA sustained damage to its landing gear as a consequence of loss of power on a test flight the day before the accident. Under the regulations, the OSC and the exemption provided by the CAA, this was supposed to have been reported, but was not. If in doubt, report?

6. Observing on the day in question, were two members of the CAA’s UAS unit, who were involved in assessing the operator’s application for exemption.

7. At the CAA UAS unit the section lead was a signatory on the exemption and he joined the CAA in May 2018. There have been numerous questions on resources that pertain to the CAA UAS unit. This is further endorsed by report which states “the CAA stated that the level of resources available meant it was not possible for the UA sector team to follow up every exemption.”

8. The CAA asked the Australian Civil Aviation Authority for further information, which does not appear to have been provided. However, the AAIB did ask CASA, and some information was provided. Does this mean that regulators will only correspond in the event of a serious incident? This is certainly going to become much more relevant for those drone operators that are operating in EU jurisdictions and how the EU intends to harmonise information in the future in order to allow drone operators to fly in different jurisdictions when qualified in another. It will be interesting to see how the UK intends to accept drone operators from the EU based upon UK regulations as these regulations may diverged in the future;

9. If you have a number of transmitters as part of your OSC that relate to redundancy, don’t leave them in the workshop!

10. The AAIB will appoint experts to examine certain aspects of the UA. In this case, experts were used to examine the circuit boards for compliance and specialist video forensic examiners using photogrammetry (interestingly from video, the expert was able to determine the UA’s heading, ground speed and altitude);

11. The AAIB compared this UA’s manufacture to EASA’s Special Conditions that relate to gliders with electric propulsion units and associated high-voltage batteries. In the event that there is an absence of regulation, comparisons will be made to other similar regulatory standards;

12. When writing mitigation measures for single points of failure, be mindful that if there is a failure in radio link communication that the UA will continue flying using its last known command. Interestingly, in this case there was no consideration on the effect of a kill switch not operating and that the hazard of a “flyaway” was not considered;

13. As a drone operator, do not state that your system has a return to home function when no GPS is fitted to the UA!

14. From an operator’s perspective, the operator in this case appears to make the admission that there was insufficient time and resources to adequately test and stabilise their equipment in unfamiliar surroundings. Additionally they stated that the team were all relatively inexperienced with aviation systems, procedures, required documentation and the need to formally understand and adhere to these processes. These are significant statements that underline the culture of an organisation in its approach to safe use of equipment and its emphasis on providing necessary training. Do your teams understand the legal obligations that relate to your operational authorisation and/or OSC?

15. As of August 2020, there are over 106,000 registered UA operators in the UK and over 45,000 operators flying model aircraft. That is a significant number of operators that require relevant training and understanding of their legal obligations;

16. According to the drones reunited website, the CAA state that most flyaways occur due to battery loss, poor signal, or a technology failure and some of this is also down to pilot error. It is essential that these aspects are covered in your risk assessment;

17. There are a number of amendments with respect to safety recommendations to CAP 722, which are:

1. 1. detailed evaluation of any unmanned aircraft systems that use on-board systems to mitigate risks with risk severity classifications of “major, hazardous or catastrophic.”
   2. guidance on the planning, completion and documenting of radiofrequency surveys to reduce the risk of radio-frequency interference or signal loss when operating unmanned aircraft systems;
   3. unmanned aircraft system operators that use unmanned aircraft which rely on a radiolinks to operate safety systems are to provide radiofrequency survey reports to the CAA for review;
   4. guidance on how to define an unmanned aircraft systems operational and safety areas, using up-to-date maps, accurate trajectory analysis and human automated safety system reaction times to ensure a safe operation;
   5. the CAA are to provide examples of unmanned aircraft system safety systems;
   6. the report recommends that the CAA introduce requirements to define a minimum standard for safety systems to be installed in unmanned aircraft systems operating under an operational authorisation to ensure adequate mitigation in the event of a malfunction;
   7. data recording systems which are capable of demonstrating compliance with the authorisations conditions, safe operation and the logging of any failures which may affect the safe operation of the unmanned aircraft system are to be required;
   8. minimum requirements for the monitoring of high-voltage stored energy devices to ensure safety of operations are recommended;
   9. operators of unmanned aircraft systems should have an effective safety management system in place prior to issuing an operational authorisation;
   10. expect an inspection from the CAA when seeking an operational authorisation for an unmanned aircraft system that the CAA have not previously had experience with;
   11. expect the CAA to adopt appropriate design, production, maintenance and reliability standards for all unmanned aircraft systems with aircraft capable of imparting over 80 J of energy, the same recommendation is made to EASA. It will be interesting to see how this develops within the new CE marking regime that is to apply in the future;

This is a really useful case study for drone operators to consider. It certainly is a timely reminder to make sure that your operational safety cases and/or OSC’s are up-to-date and that all the staff that are involved in your operation are cognisant of their legal obligations with respect to the regulations, the OSC and the exemption provided by the Civil Aviation Authority.
