Claim One:
1. A method for fusing measurements of an aircraft flight parameter on a basis of a first set of main measurements taken by a first set of so-called main sensors, and of a plurality of second sets of so-called secondary measurements taken by second sets of secondary sensors, the main measurements exhibiting a greater degree of accuracy than the secondary measurements, wherein: a discrepancy between each main measurement and the secondary measurements is calculated; a score of consistency of each main measurement with the secondary measurements is determined by the discrepancy thus obtained; for each possible fault configuration of the main sensors, a first estimation, so-called conditional, of the parameter is performed on the basis of the main measurements taken by the sensors which are not faulty in the configuration; for each fault configuration, a weighting coefficient is determined on the basis of the consistency scores of the main measurements obtained previously; an estimation of the parameter is performed by weighting the conditional estimations relating to the various fault configurations by the weighting coefficients corresponding to these configurations.
