1. Computer-assisted method for identifying parameter values for a pre-determined set of equations forming aerodynamic models of an aircraft, wherein the identification of the parameter values comprises the following steps: 000 ) storing reference aerodynamic data relating to the aircraft, 100 ) choosing a neural network method; 200 ) separating the identification of the parameter values into a plurality of partial identifications by separating linear and non-linear parts of the pre-determined set of equations forming the aerodynamic models; selecting a mode for representing the non-linear parts of the predetermined equations from one of tabulation or representation as a neural network 300 ) carrying out the partial identifications successively, 400 ) calculating a variance between the parameter values and the reference aerodynamic data, and validating parameter values for which the variance is below a pre-defined threshold, and for those parameter values for which the variance is above the pre-defined threshold, repeating steps 100 ) through 400 ) while: in step 100 ), choosing an optimization method: and in step 200 ), separating the identification of the parameter values into a plurality of partial identifications by: determining a portion of the reference aerodynamic data to be used for each partial identification.
