The air to ground or air to air communication for the civil aircraft is important for flight safety. The very high frequency (VHF) communication system is the most extensive aviation communication at present. VHF communication system is related to the audio system and realize the exterior audio communication. VHF communication system realizes the data link communication between the aircraft and the ground through cross-linking with the on-board data link system. VHF communication system is closely related to the flight safety of civil aircraft, and is also the content of airworthiness requirements. Combined with the functional requirements and design architecture of civil aircraft VHF communication system, this paper analyzes and gives the acceptable compliance method of VHF communication system according to the requirements of CCAR-25 regulations applicable to VHF communication system: airworthiness standard for transport aircraft (CCAR-25-R4-2011), and gives the approval elements of VHF communication system in airworthiness review according to model work experience. According to the terms involved in VHF communication system, CAAC has provided the approval elements and review requirements that need to be paid attention to in airworthiness review. The research is helpful to the safety design and airworthiness verification of civil aircraft VHF communication system.
