Claim One:
1. A method for merging measurements of a flight parameter of an aircraft, from measurements of the flight parameter supplied respectively by a plurality of sensors, the method comprising: searching, by a data merging module implemented on at least one processor, for a possible anomaly on one out of the plurality of sensors, wherein searching comprises: for each sensor, computing a detection deviation, proportional to the absolute value of a difference between a measurement supplied by the sensor and an estimation of the flight parameter computed from the measurements supplied by the other sensors that excludes the measurement supplied by the sensor; for each sensor, comparing the respective detection deviation for the sensor to a corresponding predetermined threshold; based on the result of the comparisons, determining the presence or the absence of an anomaly on one of the sensors with a determined total probability of false alarm; and merging, by the data merging module, measurements supplied by the sensors to provide a final estimation of the flight parameter; and transmitting, by the data merging module, the final estimation of the flight parameter to an avionic system of the aircraft.
