All airports in Qinghai Province are high plateau airports except Xining Airport, with an altitude of 3950 meters in Yushu Airport, 3787 meters in Guoluo Airport, 3163 meters in Qilian Airport, 2842 meters in Golmud Airport, 2862 meters in Delingha Airport and 2906 meters in Huatugou Airport. The airport for geographical environment, the temperature difference in the year round, in November, December, January, February, easy to appear extreme low temperature, and Germany, Yushu, luo, qilian airport every year in winter and summer, flight check, therefore, this paper to check in different seasons is affected by extreme temperature, flight altitude of instrument landing system calibration results difference are discussed, and puts forward the solution.
