The US Federal Aviation Administration (FAA) has officially approved AVSS’s PRS-M4S parachute recovery system for Category 2 “flight over people” operations on the Matrice 4E and Matrice 4T drones. In plain terms, if you operate a Matrice 4 with this parachute, you no longer need to beg the FAA for special waivers to fly over bystanders. That’s one less regulatory headache for you and a big win for drone safety.You can focus more on your project instead of paperwork.

FAA Green Light

In the past, you would have needed a Part 107.39 waiver (a hard-to-get FAA permission) to legally fly over anyone not directly involved in your operation. Those waivers were rare – between 2016 and 2020 the FAA granted only about 175 waivers for flights over people, with rejection rates once as high as 99%! 

Fortunately, the rules evolved. The FAA introduced “Categories” of drone operations over people, and Category 2 is the focus here. Under Category 2, a drone can routinely fly over people if it meets strict safety criteria – notably, limiting impact energy to under 11 foot-pounds (about 15 joules) and having no exposed sharp parts. So the drone must be designed so it can’t cause worse injury than a small falling object of that energy.

AVSS stepped up to the plate by engineering a parachute that makes the Matrice 4 meet those criteria. The FAA’s approval means the Matrice 4 with AVSS parachute is officially recognized as Category 2-compliant. No more time-consuming waiver applications are required. This is huge for public safety teams, infrastructure inspectors, delivery services – anyone who needs to fly in populated areas. You can now legally do jobs that were previously off-limits or bogged down in red tape.

Rigorous Testing and Compliance

The PRS-M4S parachute underwent the ASTM F3322-24a testing protocol – an industry standard torture-test for drone parachutes. This latest version of the standard requires 49 successful parachute deployments witnessed by a third-party testing organization. AVSS’s system passed with flying colors, deploying the chute dozens of times without a hitch. The company followed an FAA-approved Means of Compliance (a fancy term for the testing and safety process), dotting every i and crossing every t. The result was an FAA Declaration of Compliance officially listing the Matrice 4 + AVSS parachute combo as Category 2 approved (the FAA has even posted this compliance letter on its website: Matrice 4 Enterprise  & Matrice 4 Thermal). 

It’s worth noting that AVSS isn’t new to this. The Canadian-based drone safety company already secured FAA approvals for parachutes on other DJI models like the Mavic 3 series and drone dock variants. Adding the Matrice 4 series to that list widens access for more commercial operators.With the Matrice 4 now covered, operators of DJI’s latest enterprise drone can join the party. This approval fits into a broader push to integrate drones into everyday work while keeping safety front and center.

Meet the AVSS PRS-M4S Parachute System

So, what exactly is this parachute system that’s unlocking Category 2 flights for the Matrice 4? The AVSS PRS-M4S is a bolt-on Parachute Recovery System tailor-made for the DJI Matrice 4 Series. It’s a compact hardware kit that attaches securely to the drone without interfering with sensors or GPS. Despite weighing only about 149 grams (0.33 lbs), it’s packed with safety tech. Here’s what you get with the PRS-M4S:

  • Fast Automatic Deployment: The parachute can fire open in under 0.5 seconds of detecting a problem. That speedy deployment can make all the difference in a critical failure. If your drone malfunctions or free-falls, the parachute automatically launches before you even realize something’s wrong. (Of course, there’s also a manual trigger as backup, but automatic is key when split-seconds count.)
  • Flight Termination System: The kit integrates a plug-and-play flight termination system tied into DJI’s API (PSDK). The moment the parachute deploys, it cuts power to the drone’s rotors. Stopping the propellers prevents them from tangling in the chute or causing harm. It’s a crucial feature – you don’t want spinning blades under a billowing parachute.
  • Manual Trigger Device (MTD): Besides the automatic trigger, AVSS provides a handheld manual trigger so you have the option to deploy the parachute on command. This could be useful if, say, you spot an imminent collision or some hazard the auto system hasn’t detected. You’re in control when you need to be.

  • Internal Rechargeable Battery: One of the PRS-M4S’s coolest innovations is its power system. It has an internal battery that recharges in-flight from the drone’s power. That means as long as your drone has juice, the parachute’s battery stays topped up. Unlimited flight time on the parachute – no more worrying that your safety device might run out of power mid-mission. This is a first for many drone parachute systems, which often only have a fixed runtime. With AVSS, you can fly all day and the parachute is always ready.
  • Complete Kit & Rugged Case: AVSS sells the PRS-M4S as a complete package. It includes the parachute pod, the electronic module, the flight termination tie-in, the triggering system, all necessary brackets and batteries, plus the compliance paperwork to satisfy regulators. Everything comes neatly packed in a tough Nanuk hard case (great for tossing in your truck on the way to job sites). Basically, you get everything needed to install and operate the parachute system out-of-the-box – no DIY tinkering required.

All these features come at a price of $1,700 USD (MSRP) For a commercial drone outfit, $1,700 is a reasonable investment to dramatically boost safety and open up new operational possibilities. The kit is already shipping to authorized resellers, and new orders are expected to deliver by August – so you won’t have to wait long to get your hands on one if you’re eager. Considering the potential cost of an accident (liability, damaged equipment, lost business opportunities), many would say this parachute pays for itself the first time it prevents a disaster.

Key Specs at a Glance

Let’s talk performance numbers – because at the end of the day, a drone parachute is only as good as its ability to slow its descent. According to AVSS’s data, the PRS-M4S brings down a Matrice 4 with an average descent rate of ~3.8 m/s (12.5 ft/s). To put that in perspective, that’s like dropping your drone about as slowly as a gentle parachute jump, rather than a stone. This reduced descent speed translates to a dramatically lower impact energy. 

The average impact energy with the parachute is only ~9.9 joules (≈7.3 ft‑lbs). That’s comfortably below the FAA’s 11 ft-lb injury threshold for Category 2. In fact, it provides a safety margin – even if the drone fell from a substantial height, the parachute keeps the impact energy in the single digits of joules. The PRS-M4S effectively cushions the Matrice 4’s fall to a level that bystanders can walk away from.

Another spec that stands out is the 0.5-second deployment time. This is the max time it takes for the parachute to fully unfurl once triggered. A fast-opening chute is critical – every tenth of a second of free-fall means more speed and harder impact. AVSS’s system uses a pyrotechnic “energetic” deployment mechanism (a tiny controlled explosive charge) to shoot the parachute out instantly. It’s a proven method that ensures the chute catches air right away. 

Additionally, the parachute itself is built into a Parachute Pod™ which is designed for quick re-packing and re-use after deployment. The whole system has been engineered to meet not just FAA standards, but also European safety standards (like EASA’s requirements) and the ASTM consensus standards recognized globally. So this isn’t a jerry-rigged hobbyist gadget – it’s a professional-grade safety device designed to satisfy aviation regulators and real-world conditions alike.

Why Drone Parachutes Matter

You might be thinking: “I’ve been flying drones for years without a parachute, do I really need one now?” The honest answer: if you’re flying over people, absolutely yes. No matter how skilled you are or how reliable your drone is, things can go wrong – and when drones fall, they fall hard

In the United States, between 2015 and 2020, roughly 4,250 drone-related injuries were treated in emergency rooms. Among those injured, 21% were kids under 18. Drones have struck bystanders in all sorts of incidents – a toddler on a playground swing was hit by a falling drone, a man downtown had a drone smack into his face, and a woman was knocked unconscious by a drone during a parade. Most of these incidents involved small consumer drones, and luckily almost all victims recovered (in fact, 95% of injured people were treated and released without hospitalization). But these examples show the risk: a drone is a flying object with spinning blades and a battery – if it drops on someone from above, it can cut skin, break bones, or worse.

Now scale that up to an enterprise drone like the DJI Matrice 4. The Matrice 4 is a serious piece of equipment used for public safety, inspections, and mapping. When falling it could pack enough punch to seriously injure someone if it hit them directly. This is why regulators are so strict about operations over people. The FAA’s 11 ft-lb energy limit for Category 2 was chosen as a level that greatly reduces the chance of severe injury. To meet that with a multi-kilogram drone, you need a mechanism to slow the drone’s descent – enter the parachute.

Drone parachutes have proven to be an effective last line of defense. By deploying a canopy, they slash the drone’s fall speed and energy on impact exponentially. Over 90% of drone pilots who applied for FAA waivers to fly over people (pre-Category rules) used parachute systems to mitigate ground risk. I\The physics are straightforward: without a parachute, a drone that loses power or has a critical failure becomes a free-falling projectile. With a parachute, it becomes a gentle descender. Instead of a high-velocity crash, you get a controlled drop with much less force.

Think of the parachute as an insurance policy – one that protects both the people below and your expensive drone. It might not deploy often (and you hope it never has to), but if the worst happens, you’ll be incredibly thankful it’s there. Modern drone parachutes like the AVSS PRS-M4S are also designed to minimize any added risk. For instance, they trigger a flight termination so the rotors won’t keep spinning, and they deploy even if the drone loses power completely (thanks to their independent battery and sensors). In other words, they’ve got your back when all other systems fail. Using a parachute demonstrates to regulators, clients, and the public that you take safety seriously and you’re prepared for the unexpected.

Expanding What You Can Do with Your Drone (Deliveries, Inspections & More)

With the AVSS parachute on a Matrice 4, operations get more value, such as:

  • Emergency Response and Public Safety: Police, fire departments, and search-and-rescue teams often need to fly drones over crowds or responders during emergencies. Whether it’s monitoring a large public event, tracking a suspect through city streets, or surveying a disaster scene, time is of the essence. Before, even public safety agencies had to be cautious about flying over bystanders without a waiver. Now, a Matrice 4 with a parachute can legally hover over a crowd to give eyes in the sky during, say, a festival or a fire scene. This means quicker deployment and more effective responses. You can fly directly over the action to drop a radio to a lost hiker or to assess a hazardous situation, with confidence that you won’t cause harm if the drone fails. It makes drones a more reliable tool for saving lives when every second counts.
  • Infrastructure Inspection and Construction: If you’re inspecting cell towers, bridges, power lines, or high-rise buildings, you know the challenge – these structures are often near or over places where people live and work. A routine bridge inspection drone flight might inadvertently be over moving traffic or pedestrians below. With the parachute-approved Matrice 4, you can perform inspections over active roads or populated sites without shutting them down. Utilities and engineering firms can survey critical infrastructure in busy areas without the huge logistical hassle of clearing people away. This improves efficiency dramatically. Imagine being able to inspect a city skyscraper’s facade on a weekday without cordoning off the sidewalk – now possible because your drone can legally overfly people below as long as it’s parachute-equipped. Fewer road closures and work stoppages mean quicker drone inspections and less cost. It’s a boon for industries maintaining our power grids, railways, and construction projects.
  • Media and Entertainment: Covering outdoor concerts, rallies, or sports events with drones is much easier now too. Broadcasters and filmmakers can capture aerial shots over crowds with an approved parachute system in place, rather than relying on ultra-zoom lenses from a distance. This means more dynamic footage for live events and creative projects – all while complying with regulations. Event organizers will likely start requiring parachute-equipped drones for any over-people flights, and now they have a concrete solution to point to.

In all these scenarios, the common theme is flexibility and peace of mind. You can take on missions that traverse populated areas without jumping through regulatory hoops each time. The FAA approval essentially gives you a blanket OK, as long as you stick to the Category 2 operating rules (which mostly boil down to “use the approved drone+parachute combo and don’t intentionally loiter over open-air assemblies of people”). This can translate to significant time and cost savings. No more months-long wait for a waiver, no more hiring special mitigation teams to secure a site – just do your standard risk assessment, ensure your parachute system is armed and functioning, and fly the job.

From a business perspective, this could be a competitive advantage. If you adopt parachute-equipped Matrice 4 drones, you might be able to offer services your competitors can’t, or deliver results faster. Clients in utilities, construction, or public safety will appreciate that you can get the job done without excessive red tape while still upholding the highest safety standards.
