Boundary layer transition fixing for the prediction of Airbus performance is discussed. Comparative measurements were conducted on competing aircraft. The effects of strip position and grain size on transition fixing are presented. The Delta method is used to determine the difference between wind tunnel tests and flight tests. The method to predict aircraft performances based on wind tunnel tests is explained. The presented fixing technique is very time consuming. Comparison between wing profiles is possible under certain conditions. The scaling by the Delta method provides usable results. Improvements of the fixing technique are desirable.
