Research on the position accuracy of fuselage static pressure ports on civil aircraft

Modern civil aircraft heavily rely on air data sensors to precisely measure crucial parameters, including static pressure, total pressure, angle of attack, and total temperature of the airflow. These data are then processed by advanced air data computers to derive essential flight information such as altitude and speed. However, it is imperative to acknowledge that any slight inaccuracies in the installation position of the static pressure ports can directly impact the accuracy of flight altitude and speed measurements. Hence, this comprehensive research article focuses on calculating and analyzing the potential errors associated with the positioning of these pivotal static pressure ports. By providing a solid theoretical foundation, this study aims to facilitate the determination of an optimal positioning degree for static pressure ports on civil aircraft, thereby enhancing flight safety and performance.
