Equilibrium polar as measured on model of complete airplane in wind tunnel and corrected with respect to Reynolds Number by flight tests, can not be replaced by any drag calculation; if designer of new airplane type wishes to balance desired aerodynamic advantage against generally avoidable structural difficulties and put them in correct economical relation to one another, measured equilibrium polar is only practical criterion. Translated from Luftwacht, Sept. 1929.
