Method for fusing measurements of flight parameters of an aircraft, the flight parameter measurements being linked to one another by at least one equation, the method comprising the following steps: - an acquisition step, implemented by at least one acquisition module, consisting in acquiring at least one measurement of at least one flight parameter; - a first assignment step, implemented by a first assignment module, consisting in assigning respectively a first validity score to the equation or to each of the equations linking the measurements of the flight parameters to one another, the first validity score being determined by checking whether the measurement or measurements of the flight parameter or parameters are one or more solutions of the equation or equations; - a second assignment step, implemented by a second assignment module, consisting in assigning respectively a second validity score to one or more failure scenarios, each of the failure scenarios involving one or more acquisition modules, the second validity score for a failure scenario considered being determined from the first validity score or scores assigned to the equation or equations linking the measurements of the flight parameters acquired by the acquisition module or modules involved respectively in the failure scenario considered; - a determination step, implemented by a determination module, consisting in determining the validity of the measurement or measurements of the flight parameter or parameters from the second validity score or scores; - a consolidation step, implemented by a consolidation module, consisting in consolidating the measurements of the flight parameter or parameters as a function of the validity of the measurements determined in the determination step, characterized in that it further comprises a transmission step, implemented by a transmission module, consisting in transmitting the consolidated measurement or measurements of the flight parameter or parameters to a user device, and in that the second assignment step comprises the following substeps, each of the following substeps being implemented for each of the failure scenarios: - a first identification substep, implemented by a first identification submodule, consisting in identifying, from among the equation or equations, the equation or equations linking the flight parameter measurements acquired by the acquisition module or modules involved in the failure scenario, the identified acquisition module or modules further corresponding to the acquisition module or modules for which the failure scenario assumes that the acquisition module or modules provide measurements that are not wrong, - a third assignment substep, implemented by a third assignment submodule, consisting in assigning the second validity score as a function of the first validity score of the equation or equations identified in the first identification substep. - an acquisition step, implemented by at least one acquisition module, consisting in acquiring at least one measurement of at least one flight parameter;
