A method of measuring pressure changes over an airfoil at varying angles of attack. Small holes in the airfoil surface are connected to a glass manometer tube containing fluid. The fluid level rises with negative pressure and is depressed when there is positive pressure, thus indicating the pressure pattern. Normally used in wind tunnel experiments.
