SYSTEM AND METHOD FOR AIRCRAFT FAULT DETECTION

An aircraft fault detection system including at least one aircraft data logging device that captures a collection of time-series flight data, from at least one aircraft subsystem, for at least one flight leg of an aircraft flight, and an aircraft controller coupled to the at least one aircraft data logging device. The aircraft controller groups the collections of time-series flight data into a plurality of test states, the plurality of test states being determined from a plurality of training states and one or more of the test states is different from other test states in the plurality of test states, generates at least one test transition matrix based on the plurality of test states and determine anomalous behavior of the at least one aircraft subsystem based on the at least one test transition matrix, and forecasts a fault within the at least one aircraft subsystem based on the anomalous behavior.
