This paper presents a digital avionics system implementation for small aircraft. Avionics system is one of the most important systems to all kinds of aircraft. For digital avionics system integration, a hybrid data bus technology for small aircraft is developed in Avionics Laboratory. The proposed hybrid data transfer interface (HDTI) adopts some characteristics from time trigger protocol (TTP) in conjunction with the controller area node (CAN) to simplify the data bus structure and enhance system reliability in the applications. The proposed hybrid data transfer interface system is designed and fabricated for test as a preliminary solution. In addition to data bus system, a virtual flight instrument with geodetic information system (GIS) is integrated into cockpit display together with mobile communication surveillance for low altitude flight. The overall system design will bring in new era of digital avionics for small aircrafts.
