Kronos MVC4 for DJI Mavic 4 Pro

The Kronos MVC4 is an advanced safety system specifically designed for professionals using the DJI Mavic 4 Pro drone, enabling them to achieve unrivalled regulatory compliance and operational peace of mind. This essential DJI Mavic 4 Pro accessory transforms your device into an even safer and more versatile tool, especially for missions requiring Class C5 certification. By integrating both a parachute recovery system (PRS) and a flight termination system (FTS), the Kronos MVC4 is positioned as a leading solution for in-flight risk mitigation. Its main objective is to ensure the safety of airspace, property and people on the ground in the event of an incident, while paving the way for more complex flight operations in higher-risk scenarios, in line with EASA requirements.

Ingenious operation and optimum safety for Kronos MVC4

The ingenious operation of the Kronos MVC4 is based on perfect synergy between its components. In critical situations, the flight termination system (FTS drone) instantly cuts the power supply to the DJI Mavic 4 Pro’s motors, preventing any uncontrolled maneuvers. Simultaneously, the parachute recovery system (parachute drone) autonomously and almost instantaneously deploys a robust reserve parachute. This rapid deployment, in just 0.27 seconds, drastically reduces the drone’s sink rate, minimizing impact energy and protecting the aircraft and its environment. The unlimited autonomy of the detection and release system, coupled with automatic start-up and an intelligent safety lock that activates above 20 meters altitude, guarantees constant protection without pilot intervention, even in the most unforeseen situations. Landing detection is also integrated for optimum safety.

Class C5 Drone Compliance and Expanded Operations

Obtaining Class C5 drone compliance is a major challenge for operators wishing to exploit the full potential of their DJI Mavic 4 Pro within the framework of European regulations. The Kronos MVC4 conversion kit enables the drone to be upgraded from its original C2 class to C5 class. This is evidenced by compliance with MoC2511 for the Flight Termination System (FTS) and MoC2512-M2 for the Parachute Recovery System (PRS), two standards published by EASA and essential for SORA/PDRA authorization applications for high-risk flight missions. So the Kronos MVC4 is not just a safety accessory, but a passport to extensive professional operations.

Ease of use and simplified maintenance

Ease of use is at the heart of the Kronos MVC4 design. Its “Plug & Play” nature enables initial installation in just two minutes, minimizing drone downtime.

Innovative POD Replacement System

What’s more, the parachute resetting system is greatly simplified by the innovative concept of a replacement POD. After deployment, or during preventive maintenance (each POD has an expiry date), the operator can replace the old POD with a new one in just a few minutes, performing simple maintenance operations himself. This modularity ensures maximum equipment availability. The system is designed to operate in a temperature range from -5°C to 40°C, making it reliable in a variety of operating conditions.

Flexibility with Manual Activation via Klick Remote Control

For situations where human intervention is preferred or necessary, the Kronos MVC4 also offers a manual activation option with the Klick trigger remote control. Ergonomic, lightweight and featuring clear LED status indicators, this remote control features an internal battery offering up to 30 hours of autonomy. Its secure wireless connection ensures reliable communication with the parachute system, with a range of up to 1.5 kilometers in optimal conditions, offering greater flexibility and control to the remote pilot.

Conversion Process and Preservation of the DJI Manufacturer Warranty

To convert your DJI Mavic 4 Pro into a Kronos AD Mavic 4 Class C5 drone, you need to install the internal circuit-breaking system (FTS). This operation must be carried out in a workshop approved by our experts or those of a certified reseller, thus guaranteeing perfect and secure integration. It’s important to note that the DJI manufacturer’s warranty is preserved: in the event of a need for DJI after-sales service, simply dismantle the entire C5 conversion kit (PRS + FTS) before sending the drone for repair. With a total weight of just 133 grams for the PRS and FTS kit, the impact on the flight performance of the DJI Mavic 4 Pro is minimized.
