GB42590 Safety Requirements for Civil Unmanned Aerial Vehicle Systems

3.1.2

Micro unmanned aerial vehicle

An unmanned aerial vehicle with an empty weight of less than 0.25kg, a maximum flight altitude of no more than 50m, a maximum level flight speed of no more than 40km/h, wireless transmission equipment that meets the requirements of low-power short-range technology, and can be manually controlled at any time throughout the entire process.

3.1.3

Light unmanned aircraft

An unmanned aerial vehicle with an empty weight not exceeding 4kg, a maximum takeoff weight not exceeding 7kg, a maximum level flight speed not exceeding 100 km/h, and the ability to maintain airspace and be reliably monitored in accordance with airspace management requirements. It can be manually operated at any time throughout the entire process.

4.1electronic fence

Light and small unmanned aerial vehicles should provide notifications, warnings, or automatically execute flight plans to unmanned aerial vehicle operators when they detect potential or ongoing conflicts with specific geographic areas. Flight plans can choose to prevent takeoff, limit flight altitude, hover, land, return, or more.

4.2 Remote Identification

Light and small unmanned aerial vehicles conducting flight activities should actively report identification information to the comprehensive supervision service platform through the network. Unmanned aerial vehicles should automatically broadcast identification information through wireless local area network (Wi Fi) or Bluetooth during flight. The remote identification of unmanned aerial vehicles shall comply with the provisions of Appendix A.

4.3 3 Emergency Response

When light and small unmanned aerial vehicles encounter sudden situations such as data link interruption or loss, insufficient power/fuel, etc. during flight, they should have one or more handling capabilities such as hovering/hovering in the air, returning, landing, parachute opening, etc. In the event of navigation failure, notifications or warnings should be provided to the unmanned aerial vehicle operator through the control software or other methods described in the product manual.

4.4 Structural Strength

The structural strength of unmanned aerial vehicles should meet the following requirements:

a) Having sufficient strength and stiffness under various specified load conditions, the structure of unmanned aerial vehicles does not produce harmful deformations; b) When subjected to a load of 1.33 times the maximum takeoff weight, the main load-bearing structure of the unmanned aerial vehicle is not damaged.

4.6Whole machine falling

For micro and light unmanned aerial vehicles powered by lithium-ion batteries, the overall drop should meet the following requirements:

a) Adjust the battery pack of the unmanned aerial vehicle to 30% ± 2% of full charge, and the unmanned aerial vehicle can freely fall vertically from a height of 10m

Falling (see Figure 2), no explosion or fire occurs;

b) If the unmanned aerial vehicle is equipped with parachute and other fall protection measures, record the maximum fall speed of the unmanned aerial vehicle in the open parachute state

Convert this speed to the free fall height of the unmanned aerial vehicle without protective measures (referred to as the equivalent height), and conduct a drop test based on the equivalent height.
