DJI Matrice 4D Series Now Flies C6 Compliant Without A Dock

DJI has confirmed that the Matrice 4D Series C6 marking now extends to standalone operations, not just flights from the DJI Dock 3. With the right firmware and documentation, operators can fly the aircraft on a C6 compliant basis using the DJI RC Plus 2 Enterprise controller. Here is what the update means, what C6 unlocks, and what you still need to put in place.

What Changed With Matrice 4D Series C6 Compliance

The DJI Matrice 4D Series already carried the C6 class label when DJI first achieved certification in conjunction with the DJI Dock 3. That was a milestone for automated drone operations in Europe, but it left an open question for pilots who fly manually rather than from a docking station. That question now has a clear answer.

The C6 marking covers the standalone configuration when the aircraft is operated with the DJI RC Plus 2 Enterprise, subject to the required firmware and official documentation. The hardware has not changed and the label has not changed. What has changed is that the same compliance now covers both deployment methods, the dock and the standalone controller. There is one firmware condition to note. The aircraft must be running version 17.1.5 or later, so updating is the first step for anyone planning to rely on this.

What C6 Compliance Actually Means

C6 is a UAS class marking defined under EU Delegated Regulation 2019/945. It supports certain Specific Category standard scenarios, including STS-02, when the operator also meets the operational requirements under Regulation 2019/947. To carry the label, an aircraft has to meet a strict set of technical requirements built into the drone itself.

• Maximum take off mass below 25 kg, including all payloads.
• A maximum characteristic dimension no greater than 3 metres.
• A maximum horizontal speed not exceeding 50 m/s.
• A flight termination system, independent of the flight controller, that activates automatically on permanent control link loss and cannot be switched off.
• Continuous command and control link monitoring, with four signal strength levels shown to the pilot.
• Flight volume enforcement using pre programmed operational boundaries.
• Active onboard geocaging that stops the aircraft breaching its defined flight geography.

The Matrice 4D Series was engineered to satisfy all of these from the outset, which is why the label reflects hardware compliance. The standalone firmware simply extends that verified framework to controller based flights as well as dock based ones.

STS-01 And STS-02 Explained

To see why this matters, it helps to understand the difference between the two standard scenarios. STS-01 is designed for controlled urban environments using C5 class drones. It requires visual line of sight at all times, caps horizontal speed at 5 m/s, and keeps the pilot within a defined ground zone. It suits many commercial jobs, but it is fundamentally limited to visual line of sight.

STS-02 is a different class of operation. It is designed for sparsely populated areas using C6 class drones, and it permits Beyond Visual Line of Sight flight during the mission, provided the aircraft follows a pre programmed trajectory. Under STS-02, flights can reach up to 120 metres above ground level, and up to 1 km from the pilot without observers, extending to 2 km with an observer stationed within 1 km of the pilot. Visual line of sight is still mandatory for take off and landing, and dangerous goods are not permitted. This is exactly the kind of operation the M4D geocaging and flight volume systems were designed to support.

What Standalone C6 Unlocks In Practice

Standalone C6 compliance opens up professional work that was previously either impractical without a dock or out of reach under STS-01. Linear infrastructure inspection along power lines, pipelines, railways, and road corridors is classic STS-02 territory. An operator can pre programme the route, deploy the DJI Matrice 4D with its RC Plus 2 controller, and run a compliant BVLOS inspection without the logistics of installing a dock. Search and rescue work also benefits, since teams can cover vast areas or dense vegetation within the BVLOS allowance instead of repositioning pilots as the aircraft moves.

It is important to be clear about what compliance does not replace. The aircraft meeting the C6 standard satisfies the aircraft side of STS-02. The operator side remains your responsibility. That includes an STS-02 declaration or operational authorisation to your national competent authority, the relevant theoretical knowledge and practical skills certificates, an operations manual aligned with STS-02, a maintenance manual and logbook, an emergency response plan, and an observer coordination plan if you fly beyond 1 km. None of these are waived by the drone's C6 status.

FAQs

Is the DJI Matrice 4D C6 certified?

The DJI Matrice 4D Series carries the C6 class label, and that compliance now covers both DJI Dock 3 operations and standalone flights with the DJI RC Plus 2 Enterprise controller. The aircraft must be running firmware version 17.1.5 or later for the standalone configuration.

What firmware does the Matrice 4D need for standalone C6 compliance?

The aircraft must be running firmware version 17.1.5 or later. Updating to this version is the first step for any operator who wants to rely on standalone C6 compliance.

What is the difference between STS-01 and STS-02?

STS-01 covers controlled urban areas with C5 class drones, requires visual line of sight throughout, and caps speed at 5 m/s. STS-02 covers sparsely populated areas with C6 class drones and permits Beyond Visual Line of Sight flight on a pre programmed trajectory, with visual line of sight required only for take off and landing.

Does C6 compliance mean I can fly BVLOS straight away?

No. C6 compliance satisfies the aircraft side of STS-02, but you still need your own operational authorisation or declaration, pilot certificates, operations manual, and emergency planning from your national competent authority before flying BVLOS.

Final Thoughts

The Matrice 4D Series was built for C6 operations from the start, and this update confirms that the full capability is now available in both dock and standalone deployments. For operators, that means the freedom to choose the right configuration for each mission without giving up regulatory standing. As always, the aircraft is only one half of the equation, so pair the update with the correct authorisations and certificates before flying STS-02.
