Deviation Analysis of Pitot Static Probe Airflow Receiving for Civil Aircraft

Abstract The pitot static probe provides the atmospheric pitot pressure and static pressure information for the Air Data system for calculating flight parameters for flight. The installation angle of the f pitot static probe directly affects the accuracy of its airflow receiving, and directly affects the judgment of the aircraft and the crew. In this paper, we have conducted an in-depth analysis of the airflow receiving deviation of the pitot static probe, and simulated the large changes in flight parameters of a certain type of aircraft under different installation deviation angles. Finally, commonly used deviation treatment suggestions are given for the installation deviation of the full static pressure probe of a certain type of aircraft.
