pitot-static tube

A combination tube used in a pitot-static system, located on the fuselage of the aircraft. It measures the total, or ram, pressure, as well as static pressure. The ram pressure is used for the ASI (air-speed indicator) and the Mach meter. The static system is used for the altimeter and the vertical speed indicator. It consists of a pitot head, which measures the total pressure of the airflow. Vents or small holes on the side of the tube are used to pick up static pressure. See pitot pressure.

Because of concerns about the disparity in the fabric duct/steel duct diameter at the terminal connections, it was suggested that additional pressure loss tests be performed on fabric ducts using Pitot-static tubes mounted at the duct centerline, at axial locations prescribed by ASHRAE Standard 120.
