Signal Decoding Realization of Air Data Dynamics Test System

Air data system is used to calculate and indicate the flight parameters. It has very important meaning to test and diagnosis the air data system. In air data dynamics test system, the measured pressure and temperature signal should be transferred to the air data computer. After analyzed, the decoding signal Arinc429 is used to output the signal. The principle of Arinc429 signal decoding in air data system is introduced. A high efficiency air data test decoding method, the diagram of the system and the software realization are provided also.
