Key Restrictions for Drone Propeller Operations in Restricted Airspace

Understanding Restricted Airspace Categories

Definition and Scope of Restricted Zones

Restricted airspace refers to areas where drone flights are either prohibited or heavily regulated to protect public safety, national security, and critical infrastructure. These zones are defined by national aviation authorities and local governments, often based on the Civil Aviation Law and Regulations on the Administration of Unmanned Aerial Vehicle Flights. Common restricted areas include:

• Airport Surroundings: Typically extending 10 kilometers from runway centerlines and 20 kilometers from runway ends to prevent collisions with manned aircraft.

• Military and Government Facilities: Such as military bases, government buildings, and border regions, where unauthorized flights may pose security risks.

• Critical Infrastructure: Including power plants, nuclear facilities, oil refineries, and transportation hubs like railways and highways, where drone interference could disrupt operations or cause accidents.

• Crowded Public Areas: Stadiums, concert venues, and schools, where drone flights may endanger public safety during events or daily activities.

Dynamic Restrictions During Special Events

Temporary restricted zones may also be established during major events, such as political gatherings, sports competitions, or cultural festivals. For example, in 2025, a temporary no-fly zone was enforced over the Yangtze River during a dragon boat festival to ensure safety. These restrictions are often communicated through local government announcements or aviation authority platforms like the UOM (Unmanned Aerial Vehicle Operation Management) Platform.

Legal Requirements for Drone Operations in Restricted Zones

Mandatory Real-Name Registration

All drones weighing over 250 grams must be registered on the UOM Platform or via local government apps like Shanghai’s “Su Shen Ban.” Registration involves submitting drone details, including model, serial number, and owner information, and obtaining a unique identification code to be affixed to the aircraft. Failure to register may result in fines of up to 20,000 yuan or equipment confiscation.

Flight Plan Approval Process

Flying in restricted airspace requires prior approval from aviation authorities. Operators must submit flight plans at least 24 hours in advance, detailing:

• Flight time, route, and altitude.

• Purpose of the flight (e.g., aerial photography, inspection).

• Operator qualifications and drone registration details.

Approvals are typically granted within 9 hours for standard requests, though emergency missions (e.g., disaster response) may receive expedited processing. Unauthorized flights in restricted zones can lead to fines of 500–10,000 yuan and equipment seizure.

Age and Qualification Restrictions

• Minor Operators: Individuals under 18 years old may only fly micro drones (weighing less than 0.25 kg) under adult supervision. Those aged 14–18 can operate light drones (up to 4 kg) with adult guidance.

• License Requirements: Operators of small, medium, or large drones must hold valid Civil Unmanned Aerial Vehicle Operator Licenses issued by the CAAC. Training programs cover airspace regulations, emergency procedures, and technical skills, with exams assessing both theoretical knowledge and practical flight abilities.

Operational Safety Measures in Restricted Zones

Height and Distance Limitations

• Maximum Altitude: Drones must not exceed 120 meters above ground level in most restricted zones to avoid interfering with manned aircraft.

• Safe Distances: Maintain at least 50 meters from buildings and 100 meters from crowds. In forested or agricultural areas, keep a 10-meter vertical clearance from power lines to prevent electrical hazards.

Avoiding Sensitive Locations

• No-Fly Zones: Never fly near military installations, nuclear facilities, or government buildings, even if not explicitly marked as restricted. These areas are often subject to implicit restrictions under national security laws.

• Privacy Protections: Avoid capturing images of private residences, individuals, or sensitive facilities. Unauthorized surveillance may violate privacy laws and result in legal action.

Equipment and Environmental Checks

• Pre-Flight Inspections: Ensure drones are in good working condition, with functional propellers, stable GPS signals, and adequate battery levels. Install memory cards and remove cloud platform protective covers before flight.

• Weather Conditions: Avoid flying in strong winds (exceeding Beaufort Scale 6), rain, snow, or fog, as these conditions reduce control and increase accident risks. Additionally, clear flight paths of obstacles like trees and wires.

Penalties for Violating Restricted Zone Rules

Administrative Fines

• Unregistered Flights: Operators of unregistered drones may face fines of 200–20,000 yuan, depending on the severity of the violation.

• Unauthorized Flights in Restricted Zones: Fines range from 500–10,000 yuan, with equipment seizure for repeat offenders. In 2025, a drone operator in Yanji was fined 500 yuan for flying above 144 meters near an airport without approval.

Criminal Liability

• Endangering Public Safety: If a drone flight causes disruptions (e.g., delaying flights, triggering evacuations) or injuries, operators may face criminal charges under Article 114 of the Criminal Law, punishable by imprisonment of up to 10 years.

• National Security Violations: Flying drones over military bases or capturing images of sensitive facilities may constitute illegal acquisition of state secrets under Article 282 of the Criminal Law, with penalties including life imprisonment or the death penalty for severe cases.

Detention for Serious Offenses

In 2026, new amendments to the Public Security Administration Punishment Law introduced detention penalties for drone-related violations. Operators caught flying in restricted zones without approval may face 5–10 days of detention, while those causing accidents or endangering lives could receive longer sentences.

Case Studies Highlighting Restricted Zone Risks

Airport Disruptions

In 2024, a drone flying at 300 meters near Nanjing Lukou International Airport forced a passenger plane to abort its landing, causing a 25-minute delay and subsequent flight rescheduling. The operator, Li, was criminally charged with endangering public safety and faced potential imprisonment.

Military Zone Violations

In 2025, two individuals in Beijing were fined and detained for flying drones near a military airbase during rehearsals for a military parade. The drones were suspected of capturing images of military aircraft, posing a risk to national security. The operators were penalized under the Public Security Administration Punishment Law and faced additional scrutiny from national security agencies.

Critical Infrastructure Risks

In 2025, a drone operator in Xinjiang was fined and had their equipment confiscated for flying near high-voltage power lines. The drone’s propellers generated strong air currents, displacing dust and debris onto the lines and risking short circuits and power outages. The incident highlighted the physical dangers of drone operations near infrastructure, even without intentional harm.
