Claim One:
1. Tool for validation of a system ( 3 ) for monitoring at least one item of equipment on an aircraft engine ( 5 ), comprising test means ( 13 ) configured to evaluate a validation of said monitoring system ( 1 ) by applying a set of quality indicators to a volume of observation data ( 7 ) related to said equipment, characterised in that it comprises: processing means ( 11 ) configured to collect observation data related to said equipment, analysis means ( 12 ) configured to calculate a current value of at least one quality indicator on a current quantity of observation data collected by the processing means ( 11 ). analysis means ( 12 ) configured to estimate the probability that said current value of the quality indicator reaches a predetermined reliability criterion, thus forming a probabilistic reliability law estimated on a set of values of the quality indicator applicable to a corresponding set of quantities of observation data, and analysis means ( 12 ) configured to estimate a minimum quantity of observation data from said probabilistic reliability law, starting from which the value of the quality indicator reaches a predetermined reliability criterion with a probability exceeding a predetermined value, said minimum quantity of observation data corresponding to said volume of observation data that will be used to evaluate the validation of said monitoring equipment.
