Integrating a Parachute Recovery System (PRS) into a drone significantly enhances operational safety in the event of a technical failure or critical in-flight incident, such as extreme weather conditions, loss of radio communication, propulsion system malfunction, or GPS signal failure.

Parachute Recovery Systems (PRS) reduce impact forces and help minimize damage to both the drone and its surrounding environment during an emergency landing. They also play a crucial role in protecting people and property on the ground by mitigating risks associated with uncontrolled descents.

Dronavia Parachute Recovery Systems (PRS) enable a controlled emergency descent in the event of an in-flight issue by significantly reducing impact energy when the drone reaches the ground.

To achieve this, Kronos PRS feature an autonomous deployment system that automatically deploys the parachute in less than 0.27 seconds in the event of a critical failure. This is considerably faster than manual activation, which typically takes around 3 seconds, and helps ensure rapid response even when the operator cannot react in time.

Kronos PRS use the new PARA² parachute canopies, developed over ten years of research and testing. Their ultra-light design and advanced materials provide enhanced stability and efficiency, minimizing the descent rate relative to canopy surface area. The system is designed to keep the drone as level as possible during descent, helping to reduce potential damage on impact.

However, while the PRS is designed to optimize descent behavior, Dronavia cannot guarantee that the drone will remain perfectly flat during its fall. Descent behavior may vary depending on deployment conditions, such as altitude, weather, and ground characteristics.

To ensure rapid and reliable activation, Dronavia Parachute Recovery Systems (PRS) feature autonomous deployment technology. In the event of a critical in-flight issue, the system automatically deploys the parachute in less than 0.27 seconds, significantly faster than manual activation, which typically takes around 3 seconds. This rapid response greatly increases the chances of mitigating a crash or serious accident.

For added safety and operational control, Kronos PRS can also be deployed manually using the Klick remote trigger. Designed to be ergonomic, lightweight, and intuitive, the Klick remote features LED status indicators and a secure wireless connection, allowing operators to trigger a fast and controlled parachute deployment whenever needed.

Dronavia Parachute Recovery Systems (PRS) use a patented CO₂ ejection system to ensure fast and reliable parachute deployment. This technology has been extensively tested and field-proven and has been used by a large number of French professional drone operators for more than ten years. Continuous testing and incremental improvements have brought this system to a very high level of reliability.

When activated, a pressurized CO₂ cartridge at 60 bar is released in a fraction of a second, ejecting the parachute canopy out of its container. The excess gas released, as each cartridge contains several liters of CO₂, helps accelerate canopy inflation and minimize altitude loss during deployment, improving overall safety during emergency descent.

Dronavia has been developing autonomous parachute deployment technology for several years to support effective risk management during professional drone operations. This technology is mandatory for MoC 2512 (M2) compliant systems and for C5 accessory kits, in line with EASA requirements.

In the event of a critical in-flight anomaly, the system automatically deploys the parachute in less than 0.27 seconds, compared with approximately 3 seconds for manual activation. This ultra-fast response helps minimize altitude loss and significantly reduces the consequences of a loss of control.

To ensure reliable detection of abnormal flight conditions, the autonomous system continuously analyzes data from multiple onboard sensors, including the gyroscope, accelerometer, magnetometer, barometer, temperature, and humidity sensors.

Dronavia’s autonomous deployment technology has been tested and validated in accordance with EASA standards, ensuring a high level of reliability and regulatory compliance.

Installation depends on the type of drone and PRS configuration.

For Class C3 drones, Dronavia offers plug-and-play PRS accessory kits. These kits are designed to be installed directly by the drone operator, without modifying the drone. Detailed installation instructions are provided, and no specialized tools are required.

For Class C2 drones converted to Class C5, installation is performed by Dronavia or an authorized reseller. In this case, the PRS is part of an internal PRS + FTS conversion kit, which requires professional installation to ensure full regulatory compliance.

In all cases, Dronavia systems are designed for safe, reliable installation and full compliance with EASA requirements.

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.

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.

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.

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.

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.

A Direct Remote Identification (DRI) system allows a drone to broadcast essential flight and identification information digitally via Bluetooth (2.4 GHz) to nearby receivers, such as smartphones or dedicated devices.

The information transmitted typically includes the drone’s serial number, take-off location, current latitude and longitude, altitude, speed, and direction of travel.

By improving airspace awareness and traceability, DRI contributes to safer drone operations and more effective flight mission management. It also provides a valuable means of locating a drone in the event of a lost link between the aircraft and the operator.

A Direct Remote Identification (DRI) system is intended for drones that are not equipped with remote identification by default, as well as for drone manufacturers wishing to integrate this functionality directly into their aircraft.

By equipping a drone with a DRI system, operators can ensure compliance with the latest EASA regulations, allowing their drones to operate legally within the European regulatory framework. In addition to regulatory compliance, DRI improves traceability and airspace safety, contributing to more secure and responsible drone operations.

You can connect to the Direct Remote Identification (DRI) system interface directly from a smartphone or tablet using a Bluetooth connection.

Once Bluetooth is enabled on your device, simply connect to the DRI system via the dedicated interface or compatible application, which allows you to view, configure, and verify the broadcast identification information. No additional equipment is required.

This quick and intuitive access ensures that operators can easily check system status and compliance before and during operations.

Log in to the Fly ID web interface of your Direct Remote Identification (DRI) system.
Go to “Settings”, then enter the aircraft type and your operator number.

Once this information is saved, your DRI system is correctly linked to your operator number and ready for compliant operation.
