Abstract
An aircraft fault detection system including at least one aircraft data logging device configured to capture parametric flight data from at least one aircraft subsystem, and an aircraft controller coupled to the data logging device. The controller being configured to group the parametric flight data from the at least one aircraft subsystem into a plurality of test states, one or more of the test states being different from other test states in the plurality of states, generate 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 forecast faults within the at least one aircraft subsystem based on the anomalous behavior of the at least one aircraft subsystem determined from the at least one test transition matrix.
