A small quadcopter lifts off from a balcony to film a birthday party. A heavy cargo drone hauls medical supplies across a bay. Under a 2024 Chinese regulation, these two machines now live under two very different rulebooks.
The difference is not the pilot's intent. It is the weight, the altitude, and whether the aircraft can be watched and controlled from the ground.
That distinction is the backbone of the country's first dedicated law for unmanned aircraft — a document that finally gave the fast-growing sector a single set of rules.
The law, and why it exists
The Interim Regulations on the Flight Management of Unmanned Aerial Vehicles (无人驾驶航空器飞行管理暂行条例) was published in late June 2023 by the State Council and the Central Military Commission, and it took effect on January 1, 2024. It runs to six chapters and sixty-three articles and is explicitly described as the first specialized administrative regulation in this field.
Before it, operators navigated a patchwork of local notices and scattered rules. The regulation's aim is to cover the full life cycle — design, production, repair, assembly, and flight — under one framework, while still leaving room for recreational users to fly without drowning in paperwork.
Five classes by weight
The core idea is classification. Drones are sorted by performance indicators — mainly weight, flight altitude, and speed — into five tiers:
- Micro (微型): empty weight under 0.25 kilograms, maximum true height no more than 50 meters, top speed no more than 40 kilometers per hour.
- Light (轻型): empty weight no more than 4 kilograms and maximum takeoff weight no more than 7 kilograms, speed capped at 100 kilometers per hour.
- Small (小型): empty weight no more than 15 kilograms and maximum takeoff weight no more than 25 kilograms.
- Medium (中型): maximum takeoff weight no more than 150 kilograms, excluding the lighter tiers.
- Large (大型): maximum takeoff weight above 150 kilograms.
The split is deliberate. The smallest machines keep their freedom; the heaviest face scrutiny closer to manned aviation.
Registration, everyone
One rule applies across the board. Every civil drone owner must complete real-name registration before flying. There is no weight exemption: the toy-class aircraft and the industrial heavy-lift model are both entered into the national system under their owner's identity.
Flying an unregistered drone draws a corrective order from public security, a fine of up to 200 yuan, and — for serious cases — a penalty between 2,000 and 20,000 yuan. The message is that anonymity in the sky is no longer tolerated.
Licenses for the bigger ones
Operating skill is treated differently by class. Pilots of small, medium, and large civil drones must obtain a corresponding operator license from the civil aviation authority. Micro and light drones do not require a license, but their operators still must know how to fly and understand the risk warnings and rules.
The effect is a graduated ladder: casual fliers stay light-touch, while anyone commanding a machine that can do real work or real damage is expected to be certified.
The 120-meter line
Airspace is divided into controlled airspace (管制空域) and flyable airspace (适飞空域). Outside controlled zones, micro, light, and small drones may fly without an application — a deliberate concession to everyday use.
Crossing into controlled airspace requires prior approval. Controlled zones include airspace above 120 meters true height, no-fly and restricted zones, areas around airports, military districts, and certain protected sites. The 120-meter ceiling is, in practice, the line between casual flight and formal coordination.
Who enforces, and the AI link
Oversight is shared. A national air-traffic-management leading organ holds unified leadership, while civil aviation, public security, industry and information technology, and market supervision act by division. Local governments handle their own jurisdictions.
The regulation also points forward. It explicitly encourages unmanned aircraft to fuse with big data and artificial intelligence, and it tasks authorities with supporting that innovation. In practice, the same autonomy stacks that interest AI researchers are exactly what these flight rules are learning to govern.
Honest limitations
This article summarizes the regulation's structure, not an enforcement audit. The weight and speed thresholds are taken from the published text, but how aggressively local authorities police the 120-meter line or the registration rule varies by place and is not uniformly documented. The license and registration obligations apply within China's territory; foreign operators should also consult their own and bilateral rules before any cross-border flight. We have not claimed the regulation resolves every safety or privacy question — it sets a framework, and implementation detail continues to evolve through local practice.
What readers can do now
- For operators: register every civil drone by its owner identity before the first flight, and confirm which weight class your aircraft falls in before planning any mission.
- For heavier-class pilots: obtain the proper operator license from civil aviation before flying small, medium, or large drones, and file for approval before entering controlled airspace.
- For researchers: treat the 120-meter ceiling and airspace map as hard constraints when designing autonomous flight tests in China.
