The design and development of analog Air Data Computer based on ARM

Air Data Computer, referred to ADC, is an important on-board electronic equipment of Aircraft, and the performance of ADC directly affects the safety and efficiency of an Aircraft´s flight. In this paper, we let ARM as the core of Air Data Computer, and use some real objects, such as airspeed tube and the related sensor, etc. And then adopt the design ideas of modular to give the overall scheme of designing Analog Air Data Computer. This paper clearly illustrates the constitutes of Analog Air Data Computer systems and the realization process of software and hardware. And then realizing the acquisition, processing and display function of air data parameters of Air Data Computer, and providing good ideas for the design and development of Air Data Computer on small aircraft and Unmanned Aerial Vehicle (UAV).
