3 Terms and definitions
The terms and definitions defined in GB/T 38152 apply to this document.
4 General requirements
4.1 Test flight conditions
The test flight site conditions (altitude, size and surface material of the runway or landing area, etc.) and atmospheric conditions (atmospheric temperature, atmospheric pressure, etc.)
Atmospheric humidity and icing, etc.) should comply with the relevant provisions in the model technical requirements.
4.2 Test flight objects
4.2.1 General
The technical status of the test flight object (the unmanned helicopter system being tested) should comply with the model technical requirements. Unless there are special provisions, the test flight objects are still
Shall comply with the requirements of 4.2.2 and 4.2.3.
