GB/T 38924.4-2020 is part of the series of standards for environmental testing of civil light and small unmanned aircraft systems (with takeoff weights ranging from 0.25 kg to 150 kg). It specifically specifies the test methods for unmanned aircraft systems (including aircraft and ground stations) under combined temperature and altitude environmental conditions. The standard aims to evaluate the endurance of unmanned aircraft in complex environments such as high altitudes, extreme cold, or intense heat. It provides detailed requirements for test conditions, procedures, result evaluation, and reporting. The core testing relies on high-low temperature and low-pressure (temperature-altitude) test chambers capable of simulating combined environmental conditions. Such equipment can precisely control temperature, air pressure, and humidity simultaneously, and is equipped with sensors to monitor test parameters, making it a key instrument for verifying the environmental adaptability of unmanned aircraft.
