Abstract: This paper deals with the digital simulantion methods of dynamic response of analog air data computer.A simple mathematical model is derived and a computing block diagram is given.The computation is done on a SHARP PC-1500 pocket computer with using of BASIC language.The results given here show that this method is both convenient and efficient.The digital simulation method is applied to analyse the dynamic response of the analog air data computer.It is shown by the results that by using this method the dynamic response range of the system and the correct design parameters can be determined very quickly .This method is more simple, more convenient and more accurate than the analog computer simulation method.The mathematical methods adopted in the programs can widely be used in control systems.
