A system for analyzing aircraft data includes the steps of identifying a domain comprising sets of data, calculating ranges of typical values for components of the sets of data within the domain, and determining atypical components for each set of data within the sets of data based on the range of typical values calculated in the calculating step. A pre-cursor pattern to an exceedance event is determined by (a) identifying exceedance sets of data within the domain corresponding to an exceedance event, and (b) identifying common atypicalities of the exceedance sets of data. Mitigating factors for an exceedance event are determined by (a) identifying non-event sets of data within the domain in which atypicalities resembling the pre-cursor pattern exist but in which the exceedance event does not occur, and (b) identifying common atypicalities of the non-event sets of data as the mitigating factors. The consequences of an event are determined by (a) identifying event sets of data corresponding to the event, and (b) comparing the atypicalities of the event sets of data with the typical values, where the consequences are the common atypicalities of the event sets of data. Mitigating factors for the consequences of the event are determined by (a) chronologically sorting the common atypicalities of the event sets of data, and (b) identifying pairings of atypicalities comprising a mitigation and a consequence, where a mitigating factor is a mitigation that occurred when a later consequence usually did not occur or is a mitigation that did not occur when a later consequence usually did occur.
