摘　　要：阻力伞是飞机安全着陆的重要保障。阻力伞警示灯出现空中误报会造成飞行员误判,后果严重。为减少阻力伞警示灯出现误报故障,基于故障树法对飞机阻力伞警示灯误报故障进行研究,分析阻力伞总装和调试过程中存在的不足,采取控制措施,提高总装和调试的准确性,多架次验证项目有效性,直至杜绝该类故障的发生。Drag parachute is an important guarantee for the safe landing of aircraft.The occurrence of air false alarm of drag parachute warning light will cause pilot misjudgment,with serious consequences.In order to reduce the false alarm of the resistance parachute warning light,the false alarm of the aircraft resistance parachute warning light is studied based on the fault tree,and the deficiencies in the process of resistance parachute assembly and commissioning are analyzed.The control measures are increased to improve the accuracy of the final assembly and commissioning.The effectiveness of multiple sorties is verified until the occurrence of such faults is eliminated.
