Dronavia Parachute Recovery Systems (PRS) comply with MoC2512 for M2 mitigating means published by EASA. It facilitates the implementation of the Specific Operations Risk Assessment (SORA). The MoC M2 (2512) demonstrates that the drone has a feature that reduces its impact energy in the event of a crash.

Dronavia Parachute Recovery Systems (PRS) can be used in France to approve drones weighing between 2 and 8 kilograms for DGAC (Direction Générale de l’Aviation Civile) Scenario 3 (S3). This requirement aims to guarantee the safety of people and property on the ground in the event of a critical problem during flights in urban areas or when flying over people, by limiting the impact on the ground to less than 69 joules.

By combining your Parachute Recovery System (PRS) with your Flight Termination system (FTS), you can obtain an accessories kit enabling you to classify your drone C5 (for all C3 class drones). This EASA-compliant accessories kit enables you to fly in the specific category in the STS-01 scenario.

By combining your Parachute Recovery System (PRS) and your Flight Termination system (FTS), the drone becomes S1/S2/S3 approved by the DGAC.

From January 1, 2024, a new drone class, Class C5 (for specific category flights (STS-01)), will come into force throughout Europe.

The STS-01 scenario concerns line-of-sight flights at an altitude of 120 meters, whether in a populated or unpopulated environment. This flight scenario is comparable to the DGAC’s current S3 scenario.

To fly in this scenario in Europe, you need to obtain a C5 marking for your drone. There are two ways of doing this: either the manufacturer develops his drone to meet the requirements of this class, or the drone operator installs an accessories kit (or conversion kit) on his C2 or C3 class drone (DJI Mavic 3 Enterprise/ DJI Matrice 350 / DJI Inspire 3), enabling his drone to become C5 class compliant and obtain this marking.

Dronavia is proud to be the first manufacturer to offer accessories kits or conversion kits (consisting of a parachute system (PRS) and a Flight Termination System (FTS)) compliant with EASA regulations, enabling your drone to obtain the C5 class label.

To obtain C5 class marking for your DJI Matrice 350 and/or DJI Inspire 3 drone, simply install the plug and play accessories kit (PRS + FTS) offered by Dronavia. If you decide to revert to the drone’s original Class C3 marking, simply remove the accessories kit (PRS + FTS).

You retain your DJI warranty when you upgrade your drone from class C3 to class C5. To do this, simply dismantle the FTS + PRS assembly before sending your drone to DJI under warranty.

EASA has published a new compliance proposal for systems installed on drones to reduce ground impact in the event of a crash. The document is aimed at drone operators planning to fit a drone with a parachute, or to demonstrate that the drone is equipped with a function that reduces its impact energy in the event of a collision. The document is also aimed at drone manufacturers and manufacturers of Parachute Recovery Systems (PRS).

MOC2512 (M2) designates the level of robustness required for the safety system in the event of a drone losing control and falling to the ground.The three key elements of an effective M2 mitigation system are as follows:

• Reduce the effect of ground impact
• Operate reliably in the event of loss of control
• Do not introduce any additional risk

Drone manufacturers must declare that they meet these three requirements and provide evidence, in the form of tests, analyses, simulations, inspections, design reviews or operational experience, to back up these declarations.

Mitigation measures are divided into three stages:

M1 – Strategic mitigation: this stage involves implementing strategies to reduce risks at source. For example, by choosing flight routes that avoid high-risk areas, or by using technologies that reduce the risk of accidents.

M2 – Reducing effects in the event of an impact: this stage aims to minimize the consequences of an accident should it occur. For example, by using containment devices to protect people and property on the ground, or by implementing evacuation plans in the event of an accident.

M3 – Contingency planning: this stage involves putting in place protocols to manage the consequences of an accident and ensure the safety of people and property on the ground. For example, by providing emergency communications or establishing working relationships with local authorities and emergency services.

Each of these steps has a corrective value, which can reduce or increase the GRC depending on the strength of the measures put in place. The more effective the measures, the higher the correction value and the lower the GRC. If the final GRC is higher than 7, it is not possible to apply for a SORA file.

Dronavia uses a patented CO2 ejection system for its parachute systems (PRS). This ejection system has been tried and tested and used by the majority of French drone operators for over 6 years. Numerous tests and successive improvements have brought this system to unprecedented levels of reliability.

A pressurized gas (60 bar) is liberated in a fraction of a second to propel the parachute canopy out of its container. The excess gas released (each cartridge contains several liters) is used to accelerate canopy deployment and minimize altitude loss during parachute deployment.

Dronavia’s Parachute Recovery Systems (PRS) are designed for easy integration, with an installation time of around 5 to 10 minutes (for the first installation) and then only a few seconds. Dronavia provides a user manual and tutorial videos to help drone operators carry out the installation quickly and easily.

Our systems have also been designed and developed to be quick and easy to transport.

Dronavia markets Flight Termination systems (FTS) compatible with its Parachute Recovery Systems (PRS), enabling the drone’s power supply to be cut off in less than a second. The two systems are paired and coupled in our workshop by our experts. If the Flight Termination System (FTS) is activated, the Parachute Recovery System (PRS) is also automatically deployed (and vice versa).

Dronavia parachute systems (PRS) are equipped with an independent 5-hour battery that can be recharged via USB-C. Dronavia also supplies a USB-C cable (which can be connected to the drone or to a FTS) to give the PRS unlimited autonomy.

There are no constraints for drone operators traveling by air. Most airlines offer the possibility of putting your Parachute Recovery System (PRS) in the hold or in the cabin with the gas cartridge (16G / 12G / 8G / 4G).

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.

In both cases, you can either buy a new POD, or exchange your used POD for a new one at a preferential price.

Replacing your CO2 cartridge, resetting your parachute, checking your parachute’s firing pin and spring, folding your canopy… these are all operations that can be complex or dangerous. We recommend that you opt for the manufacturer’s maintenance service offered by Dronavia.

If you choose to rearm your Zephyr or IDRsys parachute system (PRS) yourself, Dronavia will void the warranty on your system.

Send us your Zephyr & IDRsys PRS systems, and our experts will carry out all maintenance work with their unique know-how. You’ll receive your system as good as new, with the warranty intact. Shipping costs are your responsibility.
