In order to verify the safe operation in the frigid environment, the civil aircraft needs to carry out an aircraft-level frigid environment special test. This article summarizes the environmental conditions of the test location for the frigid environment special test of civil aircraft, including domestic airport meteorological analysis, foreign airport meteorological analysis, and the climatic environment test facility environmental conditions. For the climatic environment test facility and the Hailar Dongshan Airport, the suggestions for the selection of the window period was demonstrated. The measurement contents and precautions related to the measurement of ambient temperature, on-board data reading, and system parameter measurement during the test were sorted out. This paper also studies the implementation methods and key points of the pre-cold soaking inspections, during cold soaking inspections, and post-cold soaking inspections of civil aircraft in the climatic environment test facility and at the Hailar Dongshan Airport, the pre-flight inspection, flight inspection and post-flight inspection of civil aircraft at the Hailar Dongshan Airport. The time suggestion for cold soaking inspection at Hailar Dongshan Airport was given. Thereby the test implementation methods of the frigid environment special test of civil aircraft was systematically demonstrated, which has certain guiding significance for planning and implementation of frigid environment special test of civil aircraft.
