A method for merging measurements of a flight parameter of an aircraft, from measurements (y1, y2, y3, y4) of this parameter supplied respectively by a plurality of sensors (C1, C2, C3, C4), comprising: for each sensor (C1; C2; C3; C4), computing a deviation (T1; T2; T3; T4), proportional to the absolute value of a difference between a measurement (y1, y2, y3; y4) supplied by this sensor, and an estimation of the parameter computed from the measurements supplied by the other sensors; comparing each deviation to a corresponding threshold (Td1; Td2; Td3; Td4); based on the comparisons, determining the presence or not of an anomaly on one of the sensors with a determined total probability of false alarm; and merging measurements to provide a final estimation of the parameter ({circumflex over (x)}).
