运输类飞机防冰除冰适航取证分析

飞机的防冰除冰能力对飞机在恶劣天气下的飞行安全有重要影响,是适航审定中十分重要的一环。通过对运输类飞机防冰除冰系统有关适航标准、相关技术性文件、咨询通报及运输类飞机防冰除冰系统适航符合性验证方法的研究,介绍了CCAR25R4（草案）中对飞机不同部件、系统的除冰防冰要求,适航性验证时对大气结冰环境参数的要求;并对几类常规的飞机防冰系统试验进行综述,对大飞机防冰除冰系统的适航取证工作提供一定的指导意义。

Analysis on Airworthiness Certification of Anti/De-icing in Transport Category Airplanes

The ability of anti-icing and de-icing of aircraft has a major impact on flight safety in adverse weather conditions,and it is a very important part of airworthiness certification.Based on the research on the airworthiness standards,related technical documentation,advisory circular and compliance verification method of the transport aircraft anti-icing and de-icing system,the CCAR25R4（draft） is introduced,which presents anti-icing and de-icing requirements in different parts and systems of the aircraft,and the requirements of atmospheric icing parameters in airworthiness validation.Finally,several kinds of conventional aircraft anti-icing systems test are reviewed,which are of certain significance to the work of airworthiness certification for large aircraft anti-icing and de-icing system.
