First of all, the article gives a general introduction to the aircraft air data system, and then discusses the design of the air data system of the aircraft. It is hoped that this study can help improve the overall level of aircraft air data system. Air data system is an important airborne electronic equipment, its performance, accuracy is directly related to the flight safety of the aircraft. On the basis of introducing the hardware and software architecture of a certain type of aircraft air data system, the ways to improve the precision of air data system are deeply studied from three aspects: the calculation model of air data; the temperature error compensation method of pressure measurement based on BP neural network; Computational static pressure source error compensation method. Its atmospheric data system has stable performance, compact structure, fast speed, high precision and simple hardware and software upgrade. Test proved that its atmospheric data system can well meet the requirements of a model aircraft.
