AIRCRAFT SYSTEM OPERATIONAL TESTING

A method (300) includes obtaining a first test matrix for a first aircraft system and a second test matrix for a second aircraft system (302). The method also includes, during a first operational test of the first test matrix, obtaining sensor data that includes second sensor data that is not specified by the first test matrix (304). The method includes evaluating a second operational test of the second test matrix by processing the second sensor data using a second analytic model of the second aircraft system (310). The method also includes generating second predicted sensor data based on the evaluation of the second operational test (312). The method includes generating a second error measure by comparing a second subset of the sensor data to the second predicted sensor data (316). The method includes determining, based at least in part on a range of the second sensor data, a test coverage metric of the second test matrix (318).
