1. A method of identifying a fault in an aircraft having at least one monitored system, the method comprising: receiving, at a controller, operational data from at least one sensor for the at least one monitored system during at least a portion of a flight; receiving, at the controller, user input data derived from aircrew behavior corresponding to the operation of the at least one monitored system; analyzing, at the controller, the operational data to identify a possible fault condition, wherein identifying the possible fault condition is based on comparing the operational data to at least one corresponding threshold related to the at least one sensor, and identifying the possible fault condition provides a data filter for the controller; analyzing, at the controller, the user input data corresponding to the possible fault condition to determine the user input data is symptomatic of the possible fault condition; in response to determining the user input data is symptomatic of the possible fault condition, identifying, by the controller, an actual fault condition; and providing an indication of the actual fault condition.
