Dronavia Parachute Moc M2 with Internal Flight Termination System MOC 2511 Kronos for Mavic 4 / C5

Kronos MVC3, MVC4, M4, and M4D Parachute Recovery Systems (PRS) use a powerful pre-stressed spring deployment mechanism to eject the parachute canopy rapidly and reliably.

This deployment system has undergone extensive testing and continuous refinement, resulting in an exceptional level of reliability and consistent performance. The spring-based mechanism ensures fast, repeatable deployment, contributing to effective impact energy reduction during emergency situations.

Rearming the Kronos Parachute Recovery System (PRS) takes just a few minutes. Simply replace the old POD with a new one, then carry out a few simple maintenance operations yourself.

These operations are explained in detail in the PRS user manual and in tutorial videos available on our YouTube channel. You can either buy a new POD, or exchange your used POD for a new one at a preferential price.

There are two types of maintenance: preventive and post-deployment. In both cases, the only operation required on Kronos Parachute Recovery Systems (PRS) is replacement of the POD. This is a quick and easy operation, which means that the drone operator never has to immobilize his drone.

A use-by date is indicated on each POD. Dronavia declines all responsibility and voids the warranty on your system if your POD has exceeded this use-by date.

Whether your POD has been used after a deployment or has reached its annual maintenance deadline, you can exchange it for a new POD at a preferential price. Simply purchase a POD exchange and send us your POD. Once we receive it, we will ship your replacement POD.

For this POD model, only the parachute canopy must be returned. Please keep the parachute module and send only the used canopy.

Exception: for the Kronos M4D system, the entire POD must be returned, including both the parachute canopy and the carbon fiber tube.

Kronos MVC3, MVC4, M4 and M4D Parachute Recovery Systems (PRS) are designed for quick and straightforward installation, allowing them to be installed or removed in less than one minute.

Installation consists of attaching the dedicated mounting bracket to the drone, clipping the parachute module onto the bracket, routing the suspension lines around the airframe, and powering on the PRS.

Dronavia provides a comprehensive user manual and step-by-step tutorial videos to guide operators through the installation process, ensuring a simple, safe, and reliable setup without the need for specialized tools.

There are no constraints for drone operators traveling by air. Most airlines offer the option of putting the Kronos Parachute Recovery System (PRS) in the hold or in the cabin.

Equipping a drone with a Flight Termination System (FTS) significantly enhances operational safety in the event of a technical failure or critical in-flight situation, such as extreme weather conditions, loss of radio link, propulsion system malfunction, or loss of GPS signal.

Dronavia’s Flight Termination Systems (FTS) are designed to immediately cut power to the drone’s propulsion system by shutting down the Electronic Speed Controllers (ESCs). This prevents the drone from leaving its authorized flight envelope and enables a safe and controlled emergency response, particularly when combined with a Parachute Recovery System (PRS).

MoC 2511 is a Means of Compliance published by EASA for light unmanned aircraft systems (UAS). It defines the requirements for the implementation of an autonomous Flight Termination System (FTS), considered an emergency measure rather than a contingency measure. This Means of Compliance entered into force on 1 January 2023.

MoC 2511, also referred to as Light-UAS.25, specifies how a drone can demonstrate compliance with the requirement to safely terminate a flight in the event of a critical failure. It is a key building block for the development of a SORA, as it supports effective risk mitigation in the specific category.

Dronavia is proud to be the first manufacturer to offer a Flight Termination System compliant with EASA MoC 2511. This compliance provides operators with a robust and recognized safety solution, facilitates SORA approval, and ensures alignment with current and future European regulatory standards.

Compliance with MoC 2511 is sufficient to meet the applicable requirements of Part 9, contributing to a high level of operational safety for complex drone missions.

To achieve MoC 2511 compliance, Dronavia conducted an extensive test and validation campaign based on the technical specifications defined by EASA. These tests included repeated activation of the Flight Termination System (FTS) in multiple conditions, such as ground tests, long-distance activation, and real operational scenarios, as well as the determination of a maximum validated operating range of up to 3 km.

In parallel with these required tests, and to further enhance the reliability and durability of our systems, Dronavia carried out more than 1,000 flight termination activations. This rigorous testing program ensures the long-term performance of the Flight Termination System and guarantees that drones equipped with Dronavia FTS can operate safely and reliably, whatever the complexity of the mission.

Communication between the Klick remote trigger and the PRS / FTS is based on advanced wireless technology using LoRa modulation, ensuring a robust and reliable link.

The system operates on the 869 MHz frequency band, which is license-free, with additional options available on 433 MHz and 915 MHz depending on regional requirements. To guarantee secure communication, 128-bit encryption is used to protect data against interception.

The system continuously monitors the quality of the radio link and alerts the operator in case of communication disturbances, ensuring full awareness and operational safety throughout the flight.

No. Communication between the Klick remote trigger and the PRS / FTS uses a secure wireless link based on advanced technology and LoRa modulation. All data is protected by 128-bit encryption, preventing interception or unauthorized commands.

In addition, the system continuously monitors the communication link and alerts the operator if any disturbance is detected, further reducing the risk of accidental or unintended deployment.

There are no constraints for drone operators traveling by air.

Yes. Dronavia Flight Termination Systems (FTS) are powered directly by the drone.

For external plug-and-play FTS, the system is installed between the drone’s batteries and the aircraft, allowing it to be powered directly by the drone’s power supply. This configuration provides the FTS with unlimited autonomy for the entire duration of the flight, without the need for an additional battery.

For internal FTS, installed as part of a C2 to C5 conversion, the system is fully integrated into the drone’s internal power architecture. The internal FTS is powered directly by the drone and permanently monitored, ensuring continuous availability and immediate response in the event of a flight termination command. This integrated design is required to meet EASA C5 and MoC 2511 compliance requirements.

In both configurations, the FTS does not rely on a separate battery, ensuring maximum reliability and operational simplicity.

Dronavia Flight Termination Systems (FTS) comply with EASA MoC 2511, which defines the requirements for flight termination functions. Compliance with this MoC helps simplify and accelerate the process of obtaining an operational authorization in the specific category, in accordance with the SORA methodology.

When a Flight Termination System (FTS) is combined with a Parachute Recovery System (PRS) compliant with EASA MoC 2512 (M2), the process of obtaining a SORA-based operational authorization is further streamlined, thanks to enhanced ground risk mitigation.

By combining a PRS and an FTS, operators can obtain an EASA-compliant accessory kit or conversion kit that enables C2 or C3-class drones to be classified as C5. This configuration allows operations in the specific category under the STS-01 scenario, in full compliance with European regulations.

A Means of Compliance (MoC) is a recognized method that allows professional drone operators and manufacturers to demonstrate compliance with EASA regulations and applicable technical standards. It provides evidence that a system or mitigation means meets the required safety and performance objectives, thereby ensuring a high level of operational safety and product reliability.
MoCs are defined and published by EASA, the European Union Aviation Safety Agency, and must be met to support regulatory compliance.

Beyond the safety and quality benefits of using systems compliant with EASA-approved MoCs, such compliance significantly facilitates the preparation of a SORA (Specific Operations Risk Assessment) or the use of a PDRA (Pre-Defined Risk Assessment). These risk assessments are required to obtain operational authorizations from the National Aviation Authority (NAA) for complex missions conducted in the specific category.

In the SORA methodology, Step 9 addresses the risk of loss of control of the aircraft and the possibility of the drone leaving the intended operational area, potentially entering adjacent areas where the risk to third parties on the ground or in the air may be higher.

At this stage, the operator must assess the characteristics of adjacent areas and determine the required level of containment, either standard or reinforced. If the aircraft is not adequately designed to prevent an uncontrolled fly-away, reinforced containment measures may be required.

For reinforced containment, the operator must either:

Declare compliance with the EASA document “Means of Compliance with Light UAS.2511 – Reinforced Containment”, or

Provide supporting evidence of compliance, such as technical descriptions, test reports, or analyses, when applying for an operational authorization.

By using a Flight Termination System (FTS) compliant with MoC 2511, operators can directly demonstrate compliance with the reinforced containment requirements of Step 9. This significantly reduces the amount of justification and documentation required in the SORA dossier, making the approval process faster and more straightforward.

Dronavia Flight Termination Systems (FTS) are designed for easy and rapid integration. For external plug-and-play FTS, the first installation typically takes 5 to 10 minutes, while subsequent installations require only a few seconds. The systems are ready to use, allowing operators to resume flight operations quickly.

To support installation, Dronavia provides a detailed user manual and step-by-step tutorial videos, enabling operators to install the system simply and safely, without specialized tools.

Dronavia also offers internal Flight Termination Systems (FTS), which are installed directly inside the drone by Dronavia experts or authorized partners. These internal systems are used for C2 to C5 conversions and ensure full regulatory compliance and optimal system integration.

The connection and synchronization between the Parachute Recovery System (PRS) and the Flight Termination System (FTS) are carried out exclusively by Dronavia experts in our workshop. The two systems are paired, coupled, and fully tested together before shipment to ensure correct and reliable operation.

Once paired, the PRS and FTS operate in a synchronized manner. When the PRS is deployed, whether through autonomous activation or manual triggering, the FTS is activated simultaneously, cutting power to the propulsion system. Conversely, activation of the FTS also automatically triggers parachute deployment.

For safety and compliance reasons, Dronavia Parachute Recovery Systems (PRS) are supplied together with a Flight Termination System (FTS). This ensures proper system integration, coordinated operation, and full compliance with applicable EASA requirements.

The communication range between the Klick remote trigger and the PRS / FTS, allowing manual activation, can reach up to 1.5 km under optimal conditions, in an unobstructed and interference-free environment.

For extended operational needs, Dronavia also offers the Klick Ultra option, which provides a range of up to 10 km under the same optimal conditions.
