How to Register an Autel EVO Max 4T in the UK

Enterprise Drone, Same Registration Rules

The Autel EVO Max 4T is designed for professional and enterprise applications — thermal imaging, search and rescue, infrastructure inspections, and precision surveying with centimetre-level RTK positioning. Despite its advanced capabilities, the registration process is identical to any other drone above 250 g in the UK.

Under the Air Navigation Order 2016 (as amended), you need:

• Flyer ID: Free online test at register-drones.caa.co.uk. 20 questions, 16/20 to pass, valid for 5 years.
• Operator ID: £10.33/year, renewed annually. Must be physically displayed on the drone.

For the individual pilot, the Flyer ID is personal. For organisations operating the EVO Max 4T as part of a fleet, a single Operator ID covers all aircraft owned by that organisation — but each pilot must hold their own Flyer ID.

Registration Process: Step by Step

1. Visit register-drones.caa.co.uk and create an account. You must be at least 18 years old to register as an operator.
2. Complete the Flyer ID test. The 20-question assessment covers UK airspace rules, privacy law, weather awareness, emergency procedures, and the Drone Code. Pass mark is 16/20. Free, untimed, retakeable immediately.
3. Register as an operator. Pay £10.33 to obtain your Operator ID (OP- followed by a unique alphanumeric code). This must be renewed every 12 months.
4. Label the EVO Max 4T. Attach your OP- label in a visible and accessible location. For the Max 4T, the underside panel or the inside of the battery compartment are common placement points. Use a durable label that can withstand outdoor conditions.

A3 Open Category Limitations

The EVO Max 4T lacks a CAA-recognised C-class marking, placing it in the A3 subcategory of the Open category. This is the most restrictive Open subcategory:

• 150 m minimum distance from residential, commercial, industrial, and recreational areas
• 120 m (400 ft) maximum altitude above ground level
• Visual line of sight (VLOS) must be maintained at all times
• No flight over uninvolved people
• Pre-flight site assessment required before every flight

For an enterprise drone like the Max 4T, the A3 restrictions are particularly problematic. Most professional use cases — building inspections, search and rescue in populated areas, infrastructure surveys near roads and railways — require operations closer than 150 m to built-up areas.

Moving Beyond A3: Specific Category Operations

Given the professional nature of most EVO Max 4T use cases, pilots will typically need to operate under the Specific category rather than the Open category. This involves obtaining an Operational Authorisation (OA) from the CAA.

Operational Authorisation Routes

• PDRA (Pre-Defined Risk Assessment): Standardised risk assessments for common operations. The CAA has published several PDRAs that allow operations in populated areas under defined conditions.
• SORA (Specific Operations Risk Assessment): A detailed, bespoke risk assessment for operations that do not fit a PDRA. This is the most flexible route but requires the most documentation.
• GVC route: Holding a General VLOS Certificate (GVC) from a CAA-approved training provider simplifies the OA application process for VLOS commercial operations.

An OA application typically requires an operations manual, a risk assessment, proof of competence (GVC or equivalent), and adequate insurance. Processing times vary but plan for several weeks.

EVO Max 4T Key Specifications for Compliance

• Maximum take-off mass: ~1,670 g (heaviest in Autel consumer/enterprise range)
• Sensor payload: Wide-angle + zoom + thermal (640x512 IR) + laser rangefinder
• RTK positioning: Centimetre-level accuracy for surveying and mapping
• Maximum flight time: ~42 minutes
• Maximum range: ~20 km (VLOS rules apply regardless)
• Class marking: None (legacy/transitional)
• UK category: A3 Open (without class marking); most operations will need Specific category OA

The thermal camera and RTK module make the Max 4T uniquely capable for inspection and surveying work, but they do not change its regulatory classification. Weight and class marking — not sensor capability — determine which category rules apply.

Insurance Requirements for Enterprise Operations

Commercial drone operations in the UK require third-party liability insurance under EC785/2004 (as retained in UK law). For an enterprise platform like the EVO Max 4T, insurance considerations go beyond basic cover:

• Minimum cover: Most commercial policies provide £1 million to £10 million third-party liability. For infrastructure inspection work near critical assets, higher limits may be required by your client.
• Equipment cover: The EVO Max 4T represents a significant investment. Hull insurance covering damage, theft, and loss is advisable in addition to liability cover.
• Professional indemnity: If you provide surveying data, thermal reports, or inspection assessments to clients, professional indemnity insurance protects against claims arising from errors in your deliverables.
• Multi-aircraft policies: If the Max 4T is part of a drone fleet, fleet policies typically offer better rates than insuring each aircraft individually.

Expect to pay £200-£500+ per year for comprehensive commercial drone insurance covering an enterprise platform like the Max 4T, depending on your operational scope and cover limits.

Thermal and RTK Operations: Additional Considerations

The EVO Max 4T's thermal imaging and RTK capabilities introduce considerations that go beyond standard registration:

• Privacy and thermal imaging: Thermal cameras can detect heat signatures from people inside buildings. This raises specific privacy concerns under the Data Protection Act 2018 and UK GDPR. Ensure your privacy impact assessment addresses thermal data capture.
• Data handling: RTK survey data and thermal imagery may contain sensitive information about infrastructure, property, or individuals. Store and transmit data securely, and ensure clients understand your data retention policies.
• Export controls: Thermal imaging equipment may be subject to export control regulations depending on the sensor specifications. This is primarily relevant if you transport the drone internationally.
• Site-specific permissions: Many infrastructure sites (power stations, railways, telecommunications masts) require operator agreements with the asset owner in addition to CAA authorisation. Confirm site access permissions before planning flights.
