PARACHUTE RECOVERY SYSTEM

The Kronos MVC3 parachute model is part of a new generation of innovative rescue parachutes, equipped with an autonomous deployement system capable of automatically detecting a crash, following a loss of altitude, a collision or an abrupt change of angle. Compatible with all DJI Mavic 3 drones (Pro/Air/Enterprise), it is the most reliable and easy-to-use system on the market to protect your drone.

be ready to fly fast

The parachute  is assembled in just a few minutes by the pilot himself, without the drone ever having to pass through our workshop. The Kronos MVC3 parachute system can be installed and uninstalled in less than 2 minute. Dronavia provides video installation tutorials as well as a user & instruction manual to make it easy to get started.

STAY FOCUS ON YOUR JOB

To reduce activation time and increase the chances of avoiding a crash and accident, Kronos parachute systems incorporate an autonomous deploiement technology. This module triggers the parachute in less than 0.27 seconds, compared with around 3 seconds for a human trigger. Stay one step ahead and fully focused on your flying missions.

Autonomous deployment system

Equipped with new autonomous deployment technology (mandatory for MOC M2 compliance), Kronos parachutes and FTS activate automatically in less than 0.27 seconds in the event of a problem. This is a significant reduction compared with the average human time of 3 seconds, and also enables a considerable reduction in the drone’s impact energy.

A soft & controlled landing

The new PARA² canopies used in Kronos parachute systems are the result of 3 years of development. Their innovative, ultra-light design and unique construction give PARA² canopies superior efficiency and stability.

The fall rate is minimised in relation to the canopy surface. Each Kronos parachute is designed so that the canopy(s) keep the drone as flat as possible during its fall in order to minimise damage on impact.

Long-range, secure transmission

The long-range communication system between the trigger remote control and the parachute/FTS is based on advanced technology and LoRa modulation. Its range can reach several kilometres in optimal conditions and a long range option allows to exceed 10 km.

The communication protocol is based on the 869 MHz frequencies, which are free of authorisation (433 and 915 MHz options available). A 128-bit encryption ensures that the data is not intercepted and the user is warned if the communication is disturbed.

Compliance with EASA MOC M2

EASA has published a new proposed means of compliance for systems installed on drones to reduce ground impact in the event of a crash. The document is aimed at drone operators who are considering fitting a drone with a parachute or demonstrating that the drone has a feature that reduces its impact energy in the event of a crash. The document is also intended for drone manufacturers and manufacturers of mitigation systems (parachute recovery systems).

The MOC M2 designates the level of robustness required for the safety system in the event of the drone losing control and falling to the ground.

Depending on the level of robustness, a correction value can reduce or increase the GRC. The more effective the measures, the higher the correction value and the lower the GRC. If the final GRC is greater than 7, it is not possible to request a SORA.

The assessment of the ground risk class (GRC) is covered by stages 2 and 3 of the SORA. The first step covers the definition of the intrinsic GRC, which is the initial level of ground risk, while the second covers the mitigation measures that can be applied to reduce the risk and achieve the final GRC.

Why equip your drone with a Parachute Recovery Systems?

Adding a Parachute Recovery Systems (PRS) to a drone can help ensure safety in the event of a technical failure or other critical problem during flight (extreme weather conditions, radio transmission failure, technical failure of the propulsion system, loss of GPS signal, etc).

The parachute recovery systems (PRS) can help cushion the impact and minimise damage to the drone and its environment during an emergency landing. It can also help protect people nearby in the event of a flight problem.

What is a MOC (Means of Compliance)?

A MoC is a way for professional drone operators to demonstrate that they comply with the regulations and standards that apply to their activities and to guarantee the quality and safety of the products they use. To obtain it, it is necessary to meet the current regulatory requirements published by the EASA, the European Union Aviation Safety Agency.

Beyond quality and safety, with a MOC compliant product, professional drone operators can obtain a SORA (Specific Operations Risk Assessment) or PDRA (Pre-Defined Risk Assessment), a flight authorization delivered for specific missions, in an easier and faster way.

What is the Ground Risk Class (GRC)?

The Ground Risk Class (GRC) assessment is covered by the steps #2 and #3 of the SORA. The first step covers the definition of the Intrinsic GRC which is the initial level of ground risk, while the second one covers the mitigations that can be applied to reduce the risk and obtain the Final GRC.

How does the Kronos MVC3 Parachute Recovery Systems protect my drone?

All our parachute recovery systems (PRS) enable an emergency landing following a problem during a flight, by drastically limiting the energy on impact.

To limit this impact energy, the new Kronos Parachute Recovery Systems (PRS) incorporate an autonomous deployment technology. This module triggers the parachute in less than 0.27 seconds, compared with around 3 seconds for a human trigger.

The new PARA² canopies used in Kronos & Zephyr parachute systems are the result of 3 years of development. Their innovative, ultra-light design and unique construction give PARA² canopies superior efficiency and stability. The sink rate is minimized in relation to the surface area of the canopy. Dronavia’s parachute systems is designed so that the canopy keep the drone as flat as possible during its fall to minimize impact damage.

However, Dronavia cannot guarantee that your drone will remain flat. This depends on the weather conditions and the triggering conditions (height, type of ground, etc.).

How is the Kronos MVC3 Parachute Recovery Systems activated?

To reduce activation time and increase the chances of avoiding a crash and accident, Kronos MVC3 incorporate an autonomous deployment technology. This module triggers the parachute in less than 0.27 seconds, compared with around 3 seconds for a human trigger.

For total safety, the Kronos MVC3 Parachute Recovery System can also be activated manually using a Klick trigger remote control.

Ergonomic, lightweight, with LED status indicators and a secure wireless connection, the Klick range of trigger remote controls lets you ensure the safety of your flights, thanks to fast, controlled activation.

How does the autonomous deployment of the Kronos MVC3 parachute work?

For several years now, Dronavia has been developing autonomous deployment technology (mandatory for MOC M2 certified systems) to help remote pilots obtain the best risk management for their flight missions. Here are some of the elements taken into account by our autonomous module: gyro, accelerometer, magnetometer, barometer, temperature, humidity, etc.

Autonomous parachute deployment technology has been tested in accordance with EASA standards.

 

What communication system is used to communicate between the Kronos MVC3 Parachute Recovery Systems and the Klick trigger remote control ?

The long-range communication system between the Klick trigger remote control and the Parachute Recovery Systems (PRS) is based on advanced technology and LoRa modulation. It has a range of up to 5 km under optimum conditions, and a long-range option can exceed 10 km.

The communication protocol is based on 869 MHz frequencies, free of authorisation (433 and 915 MHz options available). A 128-bit encryption ensures that the data is not intercepted and the user is warned if the communication is disturbed.

Can the Klick trigger system be interfered with and/or intercepted? Is there a risk of unwanted triggering?

No, all data is encrypted using a secure wireless link based on advanced technology and LoRa modulation.

128-bit encryption ensures that data is not intercepted and the user is warned if communication is disrupted.

How do I reset the MVC3 Kronos Parachute Recovery Systems?

Resetting your Kronos parachute takes just a few minutes. All you have to do is replace your triggered canopy with a new one, and then carry out a few simple maintenance operations yourself, as explained and detailed in the parachute user manual and tutorial videos.

For changing the canopy you can either buy a new POD or exchange your deployed one for a new POD at a special price.

What regulations do Dronavia's Kronos MVC3 Parachute Recovery System comply with ?

The Parachute Recovery Systems Kronos MVC3 (PRS) for DJI Mavic 3 complies with the MoC for mitigation means M2 published by the EASA. It facilitates the implementation of the Specific Operations Risk Assessment (SORA). The M2 MoC demonstrates that the drone has a feature that reduces its impact energy in the event of a crash.

By combining your Parachute Recovery Systems (PRS) and Flight Termination Systems (FTS), Dronvia is able to convert your DJI Mavic 3 enterprise drone from Class C2 to Class C5 to allow you to fly in the specific category in the STS-01 scenario.

What is the C5 class published by EASA?

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

The STS-01 scenario concerns direct-line-of-sight flights at an altitude of 120 metres, whether in a populated or unpopulated environment.

To be able 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 operator carries out a conversion through Dronavia, enabling the drone to comply with EASA label class C5.

Dronavia is proud to be the first manufacturer to offer a parachute recovery system (PRS) and a flight termination system (FTS) that comply with EASA regulations, enabling your drone to obtain the C5 class label for the DJI Mavic 3 Enterprise.

How can I get class C5 marking for my DJI Mavic 3 Enterprise (3T/3E)

To obtain a class C5 marking for your DJI Mavic 3 Enteprise (3T & 3E) drone, it’s not a question of the operator installing an accessory kit directly, but of a conversion from C2 to C5.

To carry out this conversion, the DJI Mavic 3 drone must pass through our workshop so that our experts can install an internet FTS and PRS.

So, fitted with our PRS and FTS (PRS-FTS-MOC Kronos AD Mavic 3) kit, the DJI Mavic 3E becomes a Kronos AD Mavic 3E and the DJI Mavic 3T a Kronos AD Mavic 3T.

In order to achieve C5 compliance, we started from scratch and checked all the requirements for class C5 for the drone + PRS + FTS package (unlike a kit, for which you only need to check the requirements for the kit alone).

You retain your DJI warranty, simply dismantle the FTS + PRS assembly before sending it in for warranty.

Do I keep the warranty on my DJI drone when I upgrade it to C5 class?

What is the MOC M2 published by EASA?

EASA has published a new proposed means of compliance for systems installed on drones to reduce ground impact in the event of a crash. The document is aimed at drone operators who are considering fitting a drone with a parachute or demonstrating that the drone has a feature that reduces its impact energy in the event of a crash. The document is also intended for drone manufacturers and manufacturers of mitigation systems (parachute recovery systems).

The MOC M2 designates the level of robustness required for the safety system in the event of the drone losing control and falling to the ground.

The three key elements of an effective M2 mitigation system are:

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

UAV 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 support these declarations.

How can you reduce your GRC with MOC M2 and obtain your SORA?

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 the effects in the event of an impact: this stage aims to minimise 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 – Emergency plan: 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 the local authorities and emergency services.

Each of these steps has a correction value that can reduce or increase the GRC depending on the robustness 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 greater than 7, it is not possible to request a SORA.

How does the Kronos MVC3 Parachute Recovery Systems deploy?

The Kronos MVC3 are triggered by a powerful system of pre-stressed springs. Numerous tests and successive improvements have taken this system to levels of reliability never before achieved in a parachute recovery systems.

How do I install a Dronavia Parachute Recovery Systems ?

The Kronos MVC3 Parachute Recovery System can be installed and uninstalled in less than a minute. Simply attach the adhesive bracket to the front of your drone, clip the parachute onto the bracket, pass the lines around the drone and switch on the parachute!

Dronavia provides a user manual and tutorial videos to help drone operators carry out the installation simply and quickly.

How do I stop the rotors while the parachute is deploying?

Dronavia sells Flight Termination Systems (FTS) with its Parachute Recovery Systems, enabling the engines to be switched off in less than a second. The two systems are paired and coupled in the workshop. If the FTS is triggered, the PRS is triggered automatically and conversely.

Does the Kronos MVC3 Parachute Recovery Systems require a power supply?

Dronavia rescue parachute systems are equipped with an independent 10-hour battery that can be recharged via USB-C.

Can you travel by plane with a Parachute Recovery Systems?

There are no constraints for drone operators travelling by plane.

How do I carry out maintenance on Kronos MVC3 system?

There are two types of maintenance: preventive or post-trigger, but the only operation required on Kronos MVC3 parachute systems is the replacement of the POD. This is a quick and easy operation, which means that the drone operator never has to bring his drone to a standstill.

An expiry date is indicated on each POD. Dronavia declines all responsibility and cancels the guarantee of your system if your POD has passed this expiry date. 

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