Method and system for merging measurements of flight parameters of an aircraft

A method for merging measurements of flight parameters of an aircraft, the measurements of flight parameters being linked to one another by at least one equation, comprising:

• an acquisition step, implemented by at least one acquisition module, comprising acquiring at least one measurement of at least one flight parameter;
• a first scoring step, implemented by a first scoring module, comprising attributing respectively a first validity score to the equation or to each of 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 a solution or solutions of the equation or equations;
• a second scoring step, implemented by a second scoring module, comprising attributing 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 attributed 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, comprising determining 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, comprising consolidating the measurements of the flight parameter or parameters as a function of the validity of the measurements determined in the determination step;
• and
• a transmission step, implemented by a transmission module, comprising transmitting the consolidated measurement or measurements of the flight parameter or parameters to a user device.
