Abstract

All kinds of real-time atmospheric data parameters, such as angle of attack, total pressure, total temperature and static pressure, are needed for aircraft to operate in the air. The calculation of these basic parameters can support the work of other aircraft systems. These parameters are picked up by sensors mounted in specific areas outside the fuselage [1]. Because the aircraft operates in a special high altitude and low temperature environment, if the sensor is not heated and compensated, it will lead to ice blocking of the sensor, the error of atmospheric parameters measured becomes larger, and even lead to the tragedy of aircraft destruction. When to start heating and how to control the heating logic? This paper focuses on the working principle and control logic of probe heating in civil aircraft to ensure flight safety.
