The air to ground or air to air communication for the civil aircraft is important to the 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. The VHF communication system which is related to the data link system realizes the aircraft to ground data link communication. In order to ensure the civil aircraft VHF communication system reliably and stably work, the design of VHF communication system is always concerned by the type design and airworthiness department. Furthermore, the VHF communication system design of civil aircraft is always difficult to the type design. Firstly, the VHF communization system functions were defined and a design project of the VHF communication system is proposed. Then the performance requirements of the system were proposed. Finally, the system integration requirements on board and the system function validation process were expatiated. The paper has certain guidance meaning for the type design and trouble shooting.
