CO2 PARACHUTE RECOVERY SYSTEMS

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 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 are Dronavia Parachute Recovery Systems activated?

To reduce activation time and increase the chances of avoiding a crash and accident, Dronavia parachute systems 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.

To ensure total safety, the Kronos and Zephyr parachute systems 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 enables drone operators to ensure the safety of your flights, thanks to fast, controlled activation.

How does the autonomous deployment of the 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 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 Kronos Parachute Recovery Systems?

Resetting your Kronos parachute takes just a few minutes. All you have to do is replace your triggered POD 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.

The CO2 cartridge is the only consumable to be changed on the system after deployment, and a cartridge costs just a few euros. You can either buy a new POD or exchange your deployed POD for a new one at a special price.

How do I carry out maintenance on Zephyr systems?

There are two types of maintenance: preventive and post-trigger. In both cases, replacing your CO2 cartridge, rearming your parachute, checking your parachute’s firing pin and spring, repacking your canopy… are complex or dangerous operations to carry out. We recommend that you have your maintenance carried out by the Dronavia experts.

What regulations do Dronavia's Parachute Recovery Systems comply with ?

The Parachute Recovery Systems (PRS) 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.

Dronavia Parachute Recovery Systems (PRS), can be used to approve drones weighing between 2 and 8 kilograms for scenario 3 (S3) of the French Civil Aviation Authority (DGAC). The aim of this requirement is 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 Systems (PRS) and your Flight Termination Systems (FTS), you can obtain an accessories kit enabling you to classify your drone C5 (for all C3 class drones). This EASA-certified accessories kit allows you to fly in the specific category for the STS-01 scenario.

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

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. This flight scenario is virtually the same as the DGAC’s current S3 scenario.

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 drone operator installs an accessories kit on his C3 class drone (DJI Matrice 350 / DJI Inspire 3 ), enabling his drone to be certified as C5 class.

Dronavia is proud to be the first manufacturer to offer accessories kits (consisting of a parachute recovery system (PRS) and a flight termination system (FTS)) compliant EASA regulation, enabling your drone to obtain the C5 class label.

How can I get class C5 marking for my DJI Matrice 350 / DJI Inspire 3 ?

To obtain Class C5 marking for your DJI Matrice 350 and DJI Inspire 3 drone, simply install the accessories kit (PRS & FTS) offered by Dronavia. If you decide you want to revert to the original C3 drone branding, simply remove the accessories kit (PRS & FTS).

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

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

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 Parachute Recovery Systems deploy?

Dronavia uses a patented CO2 ejection system for its parachute systems. 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 taken this system to levels of reliability never before achieved in a drone parachute recovery systems.

A pressurized gas (60 bars) is released in a fraction of a second to propel the parachute canopy out of its container. The excess gas released (each cartridge contains several litres) is used to accelerate the deployment of the canopy and minimise the loss of altitude when the parachute is triggered.

How do I install a Dronavia Parachute Recovery Systems ?

Dronavia parachutes are designed to be easily integrated, 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 simply and quickly.

Our systems have been designed and developed to be easily transportable and allow drone operators to take off 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 Parachute Recovery Systems require a power supply?

Dronavia rescue parachute systems are equipped with an independent 5-hour battery that can be recharged via USB-C. Dronavia also supplies a USB-C cable (connectable to the drone or the Flight Termination Systems) to give the parachute unlimited autonomy.

Can you travel by plane with a Parachute Recovery Systems?

There are no constraints for drone operators travelling by plane. Most airlines offer the possibility to put your parachute system in the hold or in the cabin with the gas cartridge (16G / 12G / 8G / 4G)

How do I carry out maintenance on Kronos systems?

There are two types of maintenance: preventive or post-trigger, but the only operation required on Kronos 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.

How do I reset the Zephyr Parachute Recovery Systems?

Replacing your CO2 cartridge, rearming your parachute, checking the firing pin and spring on your parachute, repacking your canopy… are all operations that can be complex or dangerous.

What is the MOC2511 published by EASA?

EASA has published a consultation document on means of compliance (MoC.2511) for light UAVs, focusing on the adoption of an autonomous Flight Termination System (FTS), defined as an emergency measure (not a contingency measure). This new certification came into force on 1 January 2023.

Dronavia is proud to be the first manufacturer to provide a system that is compliant with the MoC Light-UAS.25 published by EASA, an essential compliance in the development of a SORA.

This essential compliance in the development of a SORA (Special Operations Risk Assessment) ensures that our customers have the best risk management and safety measures for their special operations, while staying ahead of future European standards. The MOC 2511 is sufficient to meet the requirements of Part 9.

How did Dronavia achieve MOC2511 compliance?

To obtain this compliance, Dronavia had to carry out numerous tests elaborated according to precise specifications provided by the EASA: repeated triggering on the ground, at distance, in a real situation and determination of the maximum operating distance established at up to 3 km.

In parallel to these hundreds of tests, to go even further and push the reliability of our Flight Termination Systems (FTS) to the maximum, we decided to perform more than 1000 flight termination triggering in order to guarantee the proper functioning of the drone with the flight termination system for many years. A way to ensure that no matter what your special operation is, you will perform it safely.

What regulations do Dronavia's Flight Termination Systems comply with?

Dronavia’s autonomous Flight Termination Systems (FTS) modules comply with MOC 2511 published by the EASA. They make it quick and easy to obtain a specific permit to fly (SORA). Coupled with a Parachute Recovery System that complies with MOC M2 published by EASA, the safety of your flights is enhanced and obtaining a SORA is made even simpler.

Dronavia’s Flight Termination Systems are approved for DGAC Scenario 2 (S2) (French Civil Aviation Authority). Coupled with a Parachute Recovery System, the drone becomes S2 approved by the DGAC.

By combining your Parachute Recovery Systems (PRS) and your Flight Termination Systems (FTS), you can obtain an accessory kit enabling you to classify your drone C5 (for all C3 class drones). This EASA-certified accessory kit allows you to fly in the specific category for the STS-01 scenario.

What is a MOC (Means of compliance)?

An 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.

How does the MOC2511 make it quicker and easier to obtain a SORA?

Step 9 of the SORA addresses the risk of loss of control of the aircraft and flight into adjacent areas where the risk to third parties (ground or air) may be higher. If the aircraft is not adequately designed, there may be probable reasons that could lead to an exit from the area of operation.

The operator should consider the criteria for adjacent areas and determine the level of containment (standard or enhanced) for the aircraft in question. For any enhanced containment system, the operator must : « declare compliance with the provisions of the document “Means of compliance with Light UAS.2511 – Enhanced containment”, or provide evidence of such compliance (technical description, test reports, etc.) when applying for a permit. »

How do I install a Flight Termination Systems ?

Dronavia’s Flight Termination Systems are designed to be easily integrated, with an installation time of around 5 to 10 minutes (for the first installation) and then just a few seconds. Our systems are plug and play, enabling drone operators to take off quickly.
