Abstract

Digital avionics using line replaceable unit (LRU) and integrated module avionics (IMA) has been promoted into very simplified and flexible design supports in modern system. Digital data bus system using controller area network (CAN) for small aircrafts has improved the accidental event by adding time trigger [1]. However, the predictability on data transmission requires enforced. The arbitration mechanism in CAN has awarded higher priority to those high frequency data or important real time data. Some deficiency may cause unpredictable delays on lower priority message and data lose when high bus load situation. To integrate time trigger into Time Triggered CAN (TTCAN) chip can improve the time scheduling in periodic data transmission [2]. Consequently, the complexity in time sequence synchronization has brought in significant load in development. This research method classifies the data frequency and assigning the concept of time to integrate hybrid data bus System. The research goal uses concept of TTCAN on dual bus CAN system and improve disadvantage of CAN.
