民机机组氧气面罩快速佩戴适航验证要求研究

CCAR25. 1447( c) (2) ( i)条款明确了机组氧气面罩快速佩戴的要求,满足该要求对于民用飞机氧气系统适航取证至关重要。 对民用飞机机组氧气面罩快速佩戴的适航验证要求进行了研究,从条款解读、机组氧气面罩设计和布置要求、适航验证要求和适航验证方法等方面进行了分析,条款中的机组氧气面罩快速佩戴要求本质上是为了保证飞行机组在各种可预期的应急情况下能够及时获得必要的缺氧保护,同时不影响对飞机的操作。 对于机组氧气面罩快速佩戴适航验证要求,试验方法既要能包容多变的人为因素,又能综合体现佩戴试验结果。 目前 FAA 有一份咨询通告指导了该条款的符合性验证要求和详细方法,在研究 FAA 相关咨询通告的基础上,提炼总结出了开展机组氧气面罩快速佩戴的适航验证方法,为国内民用飞机机组氧气面罩快速佩戴的适航验证工作提供参考。

Airworthiness certification requirements of quick donning for crew oxygen masks of civil aircraft

CCAR25. 1447( c) (2) ( i) specifies the requirement for the quick donning of crew oxygen masks. Meeting this requirement is very important for airworthiness certification of civil aircraft oxygen system. This paper studies the airworthiness certification requirements of quick donning for crew oxygen masks of civil airplanes. It is analyzed from the aspects of regulation explanation, design and location requirement of crew oxygen masks, airworthiness certification requirements and method of compliance. Requirement for quick donning of crew oxygen masks in regulation is to ensure that flight crew members have necessary anoxic protection in case of emergency and without disturbing the pilot duties of airplane. The certification test method for crew oxygen masks quick donning should show the performance of donning test involving the variable human performance. FAA has some detail requirements for the certification test. Based on this requirement of FAA, this paper summarized a method for compliance certification test of quick donning so as to provide the guidance for compliance certification test of quick donning for crew oxygen masks.
