Digital avionics has been a standard for modern aircraft. It simplifies avionics system configuration and enhances performance in efficient and reliable environment. For most commercial jet aircraft, digital avionics system is integrated through data bus protocol for information exchange and operation control. However, the general aviation aircraft seems lack of such function to break away from the conventional analog avionics. There is a simplified demand to study and design adaptable and useful interface technology for general aviation aircraft. Considering concept of the integrated modular avionics (IMA) architecture, definition of hybrid data transfer interface (HDTI) for small aircraft is proposed with a capable standard that is enhanced from the advantages of controller area network (CAN) bus and time triggered protocol class C (TTP/C) bus. This paper brings general surveys on the technical perspectives of IMA requirements, comparisons of ARINC 629 bus, CAN bus and TTP/C bus, and a new HDTI definition to fulfill general aviation demand, performance, reliability and safety to support further design and implementation.
