Abstract
The airworthiness certification for civil airliner VHF communication radio requires device-level safety assessment . This paper briefly outlines the airborne systems and equipment safety assessment guidelines,meth-ods and process . Then it describes the failure modes for each module to compose a VHF communication radioand modular failure rate,and figures out the failure probability of single-channel architecture VHF communica-tion radio with the fault tree method recommended by SAE ARP 4761 . The estimation result indicates that itdoes not meet the fail probability requirements allocated by aircraft grade PSSA (Preliminary System Safety As-sessment). Finally,the non-similar multi-channel architecture of VHF communication radio is proposed in order to reduce the failure probability of the radio . Analysis shows that VHF communication radio with this implemen-tation architecture can achieve lower failure probability than ordinary single-channel implementation architecture VHF communication radio.关键词
