The Influence of the Wind Shears and Sensor Errors upon Aircrafts Landing Process

摘要

The paper presents a new system (automatic pilot) for the automatic control of the aircrafts flight altitude in the landing process. The system has two subsystems: the first one controls the altitude of the aircrafts in the glide slope phase of the landing process, while the second subsystem controls the altitude too, but in the flare phase (the second phase of the landing process). The paper author validated the obtained automatic pilot by numerical simulations in Matlab neglecting or taking into consideration the wind shears and sensor errors. He obtained complex Matlab/Simulink models and time characteristics (time variations of the variables involved in the landing process). The wind shears and the sensor errors do not affect the landing process. The most important graphic characteristic is the dependence between the flight altitude and the horizontal displacement.
