民用飞机在高空高速飞行过程中，若驾驶舱风挡玻璃出现孔洞，则驾驶舱门内压力急剧下降，此时驾驶舱和客舱压差迅速增大，必须通过快速卸压以平衡驾驶舱和客舱压力。如卸压不及时将会对机组人员身体造成严重伤害，同时对驾驶舱地板和结构等造成严重破坏。严重时将危及飞行员生命，使整个飞机失去控制，且有坠机发生。因此驾驶舱内必须设计有快速卸压装置。民机通常将卸压板设计在驾驶舱门上，目前有机械式卸压和电子卸压两种卸压方式，对这两种卸压方式进行了介绍分析。

If the cockpit windshields of civilian aircraft have holes in the process of high speed ,the pressure fall sharply and the differential pressure of cockpit and cabin increases quickly ,w hich must relieve pressure to balance the cockpit and cabin pressure . Such as pressure relief in a untimely manner will cause serious harm to the crew body as well as cockpit floor and structure and cause serious damage ,even to pilots’ lives to cause plane crash .So the cockpit has quick pressure relief device .The discharge pressure plate often designed on the cockpit doors .There are mechanical pressure relief and electronic pressure ,and this paper analyzes the two kinds of pressure reliefs .
