Zusammenfassung:	The invention provides a method for determining a position error correction on a static pressure measurement at an aircraft flying through a flow field by means of a Taylor expansion series. The method comprises determining the constants of such a Taylor expansion series by the successive steps of an initial determination using computational fluid dynamics and a 3D scan of the aircraft, a validation of the results by low altitude flyby's at a ground station and an extrapolation of the results to altitude by performing flight tests at constant altitude and conditions of constant atmospheric pressure.
