Abstract
The article considers the algorithm of estimation of systematic measurements of aircraft air parameters in flight, based on the application of methods of the theory of identification of dynamic systems. The main complexity of the problem under consideration is caused by the dependence of airspeed, angles of attack and slide on wind speed, since these signals, that is, airspeed, angles of attack and slide, are related to the speed of the aircraft relative to air. The main idea of the algorithm is that three projections of wind speed at the point of location of the aircraft are evaluated simultaneously with parameters characterizing the systematic errors in measuring airspeed and aerodynamic angles. The estimation is obtained through parametric identification. The simulation results, obtained on the flight simulator and confirming the efficiency of the algorithm and high accuracy of the estimates of systematic errors, are presented.
