Introduction
Standard Background and Scope of Application
This document was implemented by the Civil Aviation Administration of China in April 2022, and specifies the technical requirements for light and small logistics drones in urban environments. The standard was drafted by seven institutions including Ant Networks and the Civil Aviation Research Institute, and is mainly applicable to the system safety assessment of multi-rotor logistics drones with a maximum take-off weight of ≤25kg.
Core term definition
| Term | Definition | Technical parameters |
|---|---|---|
| Light UAV | Empty ≤4kg, maximum take-off ≤7kg | Speed ≤100km/h |
| Small UAV | Empty ≤15kg, maximum take-off ≤25kg | - |
| Multi-UAV coordination | Multiple UAVs commanded by the same control system | Sharing the same route/take-off and landing point |
Key technical requirements
4.1 Flight performance
- Wind resistance: 5.4m/s during take-off and landing, 7.9m/s during flight>
- Climb rate ≥2m/s, attitude control accuracy ±5°
- Satellite navigation accuracy: horizontal ±10m, vertical ±5m
4.2 Design features
Structural strength case: The cargo structure needs to pass the vertical direction verification with a safety factor of 3 times, which is significantly higher than the 1.5 times requirement of traditional UAVs.
| Environmental test | Standard requirements | Test duration |
|---|---|---|
| Operating temperature | -10℃~40℃ | - |
| Rain test | Moderate rain intensity (24.9mm/24h) | ≥maximum no-load sailing time |
System equipment requirements
4.3 Key subsystems
- Power unit: It needs to remain controllable when the dual motors fail, and monitor the speed/current and other parameters in real time (delay <1s)
- Navigation system: at least 2 independent subsystems with cross-check function
- Communication link: dual network backup, delay ≤1s
4.4 Safety design
Typical safety measures include: anti-loosening fasteners, mechanical blocking devices, navigation lights (visible at 300m at night), 70dB alarm sound, etc.
Implementation Recommendations
Enterprise Application Recommendations: When developing urban logistics drone systems, special attention should be paid to:
- Prioritize verification of the 3-fold safety factor of the cargo structure
- Adopt modular design to meet the requirements of multi-machine collaboration
- Establish a complete emergency response plan database
Standard Evolution Analysis
Compared with early drone standards, this document clarifies for the first time:
- Wind resistance classification requirements in complex urban environments
- Technical framework for multi-machine collaborative operation
- Special strength standards for cargo structures
