Abstract:
A method of health management and assessment for an air data probe comprises performing a calibration process for the air data probe prior to installation of the air data probe on a vehicle; performing an operational process after the air data probe is installed on the vehicle; computing residuals for individual pressure channels of the air data probe and an aggregated response function, based on outputs from the calibration process and the operational process; storing and trending the residuals over time; evaluating a trendline for the residuals against one or more threshold values; and announcing a message when one or more of the threshold values is exceeded, indicating that the health of the air data probe is compromised.
