Drone Open Category A2 Rules in the UK

What Is Open Category A2?

The UK Civil Aviation Authority divides Open Category drone operations into three subcategories: A1, A2, and A3. Each subcategory sets different rules about how close you can fly to people and what qualifications you need. A2 sits in the middle ground, designed for operators who need to fly reasonably close to people but not directly over crowds or assemblies.

A2 exists because many practical drone operations, such as property surveys, construction monitoring, and media work, require flying in areas where uninvolved people may be present. The A1 subcategory allows flights over people but only with very small, lightweight drones. A3 keeps drones far from populated areas entirely. A2 bridges that gap by permitting closer operations with appropriate qualifications and equipment.

The legal foundation for A2 operations sits within the Air Navigation Order 2016 as amended, specifically the provisions implementing the UK's retained version of the EU drone regulations following the Retained EU Law (Revocation and Reform) Act 2023. The CAA has published detailed guidance in CAP 722, which remains the primary reference document for all drone operators in the United Kingdom.

Which Drones Can Fly in A2?

Only drones carrying a C2 class marking or the UK equivalent UK2 marking are eligible for A2 operations. The class marking system was introduced to categorise drones by their risk profile, with each marking corresponding to specific technical requirements covering maximum take-off mass, speed limitations, and safety features.

C2 and UK2 drones must weigh less than 4 kilograms at take-off and must include a low-speed mode function. This low-speed mode is a critical feature because it directly affects how close you can fly to uninvolved people. When the drone operates in low-speed mode, the minimum distance from uninvolved people reduces from 30 metres to just 5 metres.

If your drone does not carry a C2 or UK2 class marking, you cannot fly it under A2 rules. Legacy drones without class markings are restricted to A1 (if under 250 grams) or A3 (if over 250 grams). This distinction matters because many popular consumer drones sold before the class marking system took effect have no mark at all.

The A2 CofC: What It Takes

To fly in subcategory A2, you need two qualifications: the Flyer ID and the A2 Certificate of Competency. The Flyer ID is the baseline qualification that all Open Category drone pilots must hold. It involves an online theory test of 40 multiple-choice questions covering basic airspace rules, safety procedures, and privacy obligations. The pass mark is 30 out of 40.

The A2 CofC is an additional, more demanding qualification. It requires self-study of the A2 syllabus followed by a proctored examination. The exam consists of 30 multiple-choice questions with a pass mark of 24 out of 30. Topics covered include:

• Meteorology and its effects on drone operations, including wind shear, turbulence, and visibility
• UAS flight performance and how factors like battery capacity, payload, and temperature affect your drone
• Technical risk mitigation, covering emergency procedures, system failures, and contingency planning
• Ground risk mitigation, focusing on assessing hazards to people and property on the surface
• Operating procedures specific to A2 operations near uninvolved people

You can take the A2 CofC exam at a CAA-approved examination centre or through an authorised online proctored session. There is no mandatory training course, though self-study materials and optional training courses are widely available. The CAA publishes recommended study material on its website.

Distance Rules in A2

The distance requirements in A2 are the defining feature of this subcategory. At standard operating speed, you must maintain a minimum horizontal distance of 30 metres from any uninvolved person. An uninvolved person is anyone who is not participating in the drone operation and has not given consent to be part of it.

When you activate your drone's low-speed mode, the minimum distance reduces to 5 metres. Low-speed mode limits the maximum speed of the drone and ensures that, in the event of a collision, the kinetic energy transferred to a person is reduced to acceptable levels. The exact speed threshold depends on the drone's class marking specification.

Regardless of speed mode, you must never fly directly over assemblies of people. An assembly is defined by the CAA as a gathering where the density of people prevents individuals from easily moving away. Markets, concerts, sports events, and queues all qualify as assemblies. Flying over an assembly, even at low speed, takes the operation outside of A2 and into the Specific Category, which requires an Operational Authorisation.

Practical Scenarios for A2

A2 operations suit a range of professional and semi-professional tasks. Typical A2 scenarios include roof inspections where the property is in a residential area, construction site surveys where workers or the public may be nearby, real estate photography requiring close approaches to buildings adjacent to roads, and media production work in semi-urban settings.

In each case, the operator must conduct a pre-flight risk assessment considering the number of uninvolved people in the area, their proximity to the planned flight path, weather conditions, and potential failure scenarios. While A2 does not require a formal Operational Authorisation, the CAA expects operators to document their risk assessments and demonstrate due diligence.

Insurance and Registration

All A2 drone operations require the operator to be registered with the CAA and to hold a valid Operator ID displayed on the drone. If the operation is commercial or any element of the flight creates third-party risk, adequate insurance is essential. While the Air Navigation Order does not explicitly mandate insurance for all recreational flights, the CAA strongly recommends it, and many landowners require proof of insurance before granting permission to fly.

For commercial A2 operations, public liability insurance with a minimum cover of one million pounds is standard industry practice. Many professional organisations and membership bodies offer insurance as part of their membership packages.

Common Mistakes in A2

Several errors frequently arise among A2 operators. Flying a drone without a C2 or UK2 class marking under A2 rules is the most common, often because operators assume that holding the A2 CofC alone is sufficient regardless of the drone used. The qualification and the equipment are both required.

Another frequent mistake is misjudging the 30-metre distance from uninvolved people. In urban and suburban environments, pedestrians can enter the area unexpectedly. The responsibility to maintain the required separation distance rests entirely with the pilot. If someone walks within 30 metres during a standard-speed flight, the pilot must increase distance or land.

Confusing assemblies with groups is also problematic. A handful of people standing on a pavement is not an assembly. A crowd gathered at a bus stop during rush hour may be. The test is whether the density prevents people from easily moving away, and this requires on-the-ground judgement from the pilot.

Moving Beyond A2

If your intended operation cannot stay within the 30-metre or 5-metre limits, or if you need to fly over assemblies, in controlled airspace, or beyond visual line of sight, you move into the Specific Category. This requires an Operational Authorisation from the CAA, which involves a more detailed risk assessment process. For many professional operators, starting with A2 and progressing to Specific Category operations as their work demands is a natural career path.
