Converting the signals from analog into digital may increase its accuracy and elevate its access capability. This paper combines various software and hardware design for the multiple applications in ultralight avionics. According to this concept, each parameter is constrained by its normal and abnormal conditions to be monitored in the built-in test (BIT) functions. When any of the parameter overtakes the constraint, all monitored parameter data will be recorded and reported on-line to the ground center. These records can help the maintenance engineers to know what warring condition on the aircraft has happened, so also help them to repair the aircraft. To design this BIT, we utilize the embedded system and C language programming to handle parameter signals simultaneously for acquisition, identification and transmission. Only abnormal parameter data are recorded and sent to ground center through GSM/GPRS module for data communication. This research achieves the real-time data communication and monitoring for ultralights toward the goal of “Black-box on the Ground”.
