This paper describes the flight test technique for a certain model airplane＇s stall/spin motion according to the needs of the parameters test. This technique consists of measuring principles, methods, system composition, execution steps and methods ,data-processing flow and accuracy checking, etc. This technique is indeed practical, safe and the results are credible, precise, through more than ten sorties flight test. The results can fully meet the requirement of the plane＇s stall/spin flight test, and it is good to apply this technique for congener flight test tasks.
