1 Scope

This part of GB/T 38924 specifies the civil light and small unmanned aerial vehicle (take-off weight 0.25kg~150kg) system (including aircraft and

Ground station) vibration test requirements and methods, including test conditions, test equipment and instruments, test process, test interruption and recovery, test results

Evaluation and test reports, etc.

This part is applicable to light and small civilian use (maximum take-off weight greater than 0.25kg) that may experience a vibration environment during transportation and use.

And not more than 150kg) multi-rotor UAV system, fixed-wing UAV system, unmanned helicopter system and vehicle-mounted ground station to determine

Whether the civil light and small UAV system can withstand the impact of the vibration environment.
