Abstract
A device or system for prognostic health monitoring (PHM) of aircraft-based analog angle of attack (AoA) sensors includes a data coordinator for sampling AoA data collected by one or more AoA sensors. The data coordinator concurrently samples sensor health data from a suite of monitoring sensors within each AoA sensor (e.g., orientation, voltage, current, temperature). Based on the analog AoA data and sensor health data, the data coordinator determines a sensor responsiveness factor (RF) for each reporting analog AoA sensor. Current RF data is compared to historical RF data to determine a trending responsiveness factor for each analog AoA sensor. If the responsiveness factor for any AoA sensor trends beyond a threshold level, the data coordinator generates an alert for preventive maintenance personal on the ground, the alert indicative of one or more specific fault conditions in that AoA sensor depending on the responsiveness threshold breached.
