A method is described by which concentration distortion of particulates of arbitrary sizes caused by airflow around airplane fuselages can be calculated. The method accounts for effects of: three-dimensional details of the fuselage shape on airflow, angle-of-attack on airflow, altitude, interaction of the particles with the airflow, and particle settling. It has been applied to hydrometeor sampling instruments on three cloud physics airplanes: Lockheed C130A and C130E transports, and a Cessna Citation jet. Detailed results for water drops and ice columns are presented.
