How to Register a DJI Inspire 3 in the UK

Why Registration Is Mandatory

The DJI Inspire 3 has a maximum take-off mass (MTOM) of approximately 3,995 grams, depending on the battery configuration used. At nearly 4 kilograms, it is far above the 250g threshold that triggers CAA registration requirements. Every person who flies the Inspire 3 in UK airspace must hold a valid Flyer ID, and the organisation or individual responsible for the drone must have an Operator ID.

The Inspire 3 is a professional cinema drone built for high-end film and television production. It features the Zenmuse X9-8K Air gimbal camera, capable of recording 8K CinemaDNG RAW footage. The platform supports dual-operator mode, where one person pilots the aircraft while a second controls the camera independently. This level of capability places the Inspire 3 firmly in the professional category, where understanding both registration and operational rules is critical.

Registration Process

The basic CAA registration applies to all drones over 250g, including the Inspire 3:

1. Flyer ID: Each pilot must complete the free online theory test through the CAA drone registration service. The test covers airspace rules, privacy requirements, and safe operating practices. The Flyer ID is issued immediately upon passing.
2. Operator ID: The person or organisation responsible for the drone must register as an operator. The annual fee is £10.33. The Operator ID must be displayed on the aircraft.
3. Display your Operator ID: Attach the Operator ID to the Inspire 3 where it can be read without tools. An adhesive label on the fuselage or landing gear is common for professional drones of this size.

In a dual-operator setup, both the pilot and the camera operator should hold their own Flyer IDs, though only one Operator ID is needed per drone.

Open A3 vs Specific Category

As a legacy drone without a class mark, the Inspire 3 defaults to the Open A3 subcategory when flown under basic rules. The A3 restrictions are as follows:

• 150-metre distance: Maintain at least 150 metres from residential, commercial, industrial, and recreational areas.
• 50-metre distance from people: Never fly over uninvolved people, and keep at least 50 metres of horizontal distance.
• 120-metre altitude limit: Do not exceed 120 metres (400 feet) above ground level.
• Visual line of sight: You or an appointed observer must see the drone with the unaided eye at all times.

However, many professional filming operations require flying closer to buildings, people, or in controlled airspace. These scenarios typically exceed the limits of the Open A3 subcategory. When that happens, you need to apply for an Operational Authorisation (OA) from the CAA, which moves your operation into the Specific category.

When You Need an Operational Authorisation

An Operational Authorisation is required when your planned operation cannot meet Open category rules. Common scenarios for Inspire 3 operators include:

• Flying within 150 metres of built-up areas for film shoots, property videography, or event coverage.
• Flying closer than 50 metres to people involved in a production (actors, crew) or near uninvolved bystanders.
• Operating in controlled airspace around airports or in other restricted zones.
• Flying beyond visual line of sight for extended survey or mapping work.

To apply for an OA, you must submit a safety case to the CAA demonstrating that you have assessed the risks and put appropriate mitigations in place. This typically requires holding a GVC (General VLOS Certificate) or equivalent qualification, having an operations manual, and maintaining adequate insurance. The CAA processes OA applications on a case-by-case basis, and processing times can vary.

Insurance for Professional Operations

While recreational drone insurance is not legally mandated in the UK, the Inspire 3 is almost exclusively used for professional work. Commercial drone operators should carry third-party liability insurance as standard practice. At nearly 4 kilograms with large propellers and powerful motors, the Inspire 3 presents a significant risk in the event of a malfunction or collision.

Most professional drone operators carry a minimum of £1 million in public liability cover, with many clients and production companies requiring £5 million or more. Insurance providers who specialise in drone operations can tailor policies to cover specific filming scenarios, including work in urban environments, near structures, or over water.

If you are contracting for film, television, or commercial clients, they will almost certainly require proof of insurance before allowing you on set. Ensure your policy covers the Inspire 3 by name or by weight class and that it includes the specific types of operations you intend to perform.

Key Rules Summary

• MTOM: approximately 3,995g — registration required.
• Flyer ID (free) + Operator ID (£10.33/year) — both mandatory.
• Open A3 by default: 150m from built-up areas, 50m from people.
• Professional filming near buildings or people: Operational Authorisation likely needed.
• Maximum altitude: 120m (400 ft) above ground level under Open category.
• Dual-operator mode: both pilot and camera operator should hold Flyer IDs.
• Commercial insurance is essential for professional filming work.
• Never fly in a Flight Restriction Zone without explicit CAA authorisation.
